    Incorrect

    • A 12-year-old boy presents with double vision. He is holding his head tilted to the left-hand side. On examination of his eye movements, you note that both eyes can look normally to the right, but on looking to the left, his left eye cannot turn outwards past the midline. The right eye is unaffected when looking to the left.
      What is the SINGLE most likely nerve to be involved in this case?

      Your Answer: Left trochlear nerve

      Correct Answer: Right abducens nerve

      Explanation:

      This patient is experiencing a condition called right-sided abducens nerve palsy, which means that their sixth cranial nerve is paralyzed. As a result, the lateral rectus muscle, which is responsible for moving the eye outward, is also paralyzed. This means that the patient’s right eye is unable to turn outward. This can lead to a condition called convergent strabismus, where the eyes are not aligned properly, and diplopia, which is double vision. To compensate for the double vision, patients often tilt their head towards the side of the paralyzed muscle.

    Correct

    • A 35-year-old patient arrives at the emergency department with a 2-hour history of sporadic coffee ground vomiting. You determine that a formal risk assessment is necessary. Which tool would be the most suitable for the initial evaluation?

      Your Answer: Blatchford score

      Explanation:

      The Blatchford score, also known as the Glasgow-Blatchford Bleeding Score, is a commonly used tool to evaluate individuals who present with an acute upper gastrointestinal bleed. It is recommended by NICE (National Institute for Health and Care Excellence) that healthcare professionals use specific risk assessment scores for patients with this condition. The Blatchford score is used for initial assessment, while the full Rockall score is used after endoscopy.

      The Blatchford score consists of 9 criteria, including gender, urea levels, hemoglobin levels, systolic blood pressure, pulse rate, presence of melena (black, tarry stools) at presentation, syncope (fainting) at presentation, presence of hepatic disease, and presence of cardiac failure. These criteria are used to determine the patient’s risk level. A calculator for the Blatchford score can be found in the links section.

      Further Reading:

      Peptic ulcer disease (PUD) is a condition characterized by a break in the mucosal lining of the stomach or duodenum. It is caused by an imbalance between factors that promote mucosal damage, such as gastric acid, pepsin, Helicobacter pylori infection, and NSAID drug use, and factors that maintain mucosal integrity, such as prostaglandins, mucus lining, bicarbonate, and mucosal blood flow.

      The most common causes of peptic ulcers are H. pylori infection and NSAID use. Other factors that can contribute to the development of ulcers include smoking, alcohol consumption, certain medications (such as steroids), stress, autoimmune conditions, and tumors.

      Diagnosis of peptic ulcers involves screening for H. pylori infection through breath or stool antigen tests, as well as upper gastrointestinal endoscopy. Complications of PUD include bleeding, perforation, and obstruction. Acute massive hemorrhage has a case fatality rate of 5-10%, while perforation can lead to peritonitis with a mortality rate of up to 20%.

      The symptoms of peptic ulcers vary depending on their location. Duodenal ulcers typically cause pain that is relieved by eating, occurs 2-3 hours after eating and at night, and may be accompanied by nausea and vomiting. Gastric ulcers, on the other hand, cause pain that occurs 30 minutes after eating and may be associated with nausea and vomiting.

      Management of peptic ulcers depends on the underlying cause and presentation. Patients with active gastrointestinal bleeding require risk stratification, volume resuscitation, endoscopy, and proton pump inhibitor (PPI) therapy. Those with perforated ulcers require resuscitation, antibiotic treatment, analgesia, PPI therapy, and urgent surgical review.

      For stable patients with peptic ulcers, lifestyle modifications such as weight loss, avoiding trigger foods, eating smaller meals, quitting smoking, reducing alcohol consumption, and managing stress and anxiety are recommended. Medication review should be done to stop causative drugs if possible. PPI therapy, with or without H. pylori eradication therapy, is also prescribed. H. pylori testing is typically done using a carbon-13 urea breath test or stool antigen test, and eradication therapy involves a 7-day triple therapy regimen of antibiotics and PPI.

    Correct

    • You are resuscitating a trauma patient who is 42 years old and your consultant asks you to perform a central venous catheter insertion. During your discussion, you consider which approach carries the greatest risk of pneumothorax.

      Your Answer: Subclavian

      Explanation:

      The subclavian approach for central lines carries the highest risk of pneumothorax. However, it does have advantages such as being accessible during airway control and having easily identifiable landmarks for insertion, even in obese patients. It is important to note that the carotid is not used for CVC’s.

      Further Reading:

      A central venous catheter (CVC) is a type of catheter that is inserted into a large vein in the body, typically in the neck, chest, or groin. It has several important uses, including CVP monitoring, pulmonary artery pressure monitoring, repeated blood sampling, IV access for large volumes of fluids or drugs, TPN administration, dialysis, pacing, and other procedures such as placement of IVC filters or venous stents.

      When inserting a central line, it is ideal to use ultrasound guidance to ensure accurate placement. However, there are certain contraindications to central line insertion, including infection or injury to the planned access site, coagulopathy, thrombosis or stenosis of the intended vein, a combative patient, or raised intracranial pressure for jugular venous lines.

      The most common approaches for central line insertion are the internal jugular, subclavian, femoral, and PICC (peripherally inserted central catheter) veins. The internal jugular vein is often chosen due to its proximity to the carotid artery, but variations in anatomy can occur. Ultrasound can be used to identify the vessels and guide catheter placement, with the IJV typically lying superficial and lateral to the carotid artery. Compression and Valsalva maneuvers can help distinguish between arterial and venous structures, and doppler color flow can highlight the direction of flow.

      In terms of choosing a side for central line insertion, the right side is usually preferred to avoid the risk of injury to the thoracic duct and potential chylothorax. However, the left side can also be used depending on the clinical situation.

      Femoral central lines are another option for central venous access, with the catheter being inserted into the femoral vein in the groin. Local anesthesia is typically used to establish a field block, with lidocaine being the most commonly used agent. Lidocaine works by blocking sodium channels and preventing the propagation of action potentials.

      In summary, central venous catheters have various important uses and should ideally be inserted using ultrasound guidance. There are contraindications to their insertion, and different approaches can be used depending on the clinical situation. Local anesthesia is commonly used for central line insertion, with lidocaine being the preferred agent.

    Correct

    • While examining a 68-year-old man, you detect an ejection systolic murmur. The murmur does not radiate, and his pulse character is normal.
      What is the SINGLE most likely diagnosis?

      Your Answer: Aortic sclerosis

      Explanation:

      Aortic sclerosis is a condition that occurs when the aortic valve undergoes senile degeneration. Unlike aortic stenosis, it does not result in any obstruction of the left ventricular outflow tract. To differentiate between aortic stenosis and aortic sclerosis, the following can be used:

      Feature: Aortic stenosis
      – Symptoms: Can be asymptomatic, but may cause angina, breathlessness, and syncope if severe.
      – Pulse: Slow rising, low volume pulse.
      – Apex beat: Sustained, heaving apex beat.
      – Thrill: Palpable thrill in the aortic area can be felt.
      – Murmur: Ejection systolic murmur loudest in the aortic area.
      – Radiation: Radiates to carotids.

      Feature: Aortic sclerosis
      – Symptoms: Always asymptomatic.
      – Pulse: Normal pulse character.
      – Apex beat: Normal apex beat.
      – Thrill: No thrill.
      – Murmur: Ejection systolic murmur loudest in the aortic area.
      – Radiation: No radiation.

    Correct

    • A 12-year-old boy comes in with complaints of double vision. He is holding his head tilted to the left-hand side. During the examination of his eye movements, it is observed that both eyes can look normally to the right, but on looking to the left, his left eye cannot turn outwards past the midline. The right eye is unaffected when looking to the left.
      Which muscle is the MOST likely to be involved in this case?

      Your Answer: Lateral rectus

      Explanation:

      This patient is experiencing a condition called right-sided abducens nerve palsy, which means that their sixth cranial nerve is paralyzed. As a result, the lateral rectus muscle, which is responsible for moving the eye outward, is also paralyzed. This means that the patient’s right eye is unable to turn outward. This can lead to a condition called convergent strabismus, where the eyes are not aligned properly, and diplopia, which is double vision.

    Correct

    • A 60-year-old woman presents with intense pain in her left eye and sudden vision loss in the same eye. She has experienced multiple episodes of vomiting. After conducting a comprehensive examination and measuring the intraocular pressure, you diagnose her with acute closed-angle glaucoma. You provide analgesics and administer IV acetazolamide as the initial treatment.
      What other treatment option could potentially benefit this patient?

      Your Answer: Topical pilocarpine

      Explanation:

      This patient has presented with acute closed-angle glaucoma, which is a serious eye condition requiring immediate medical attention. It occurs when the iris pushes forward and blocks the fluid access to the trabecular meshwork, leading to increased pressure within the eye and damage to the optic nerve.

      The main symptoms of acute closed-angle glaucoma include severe eye pain, decreased vision, redness around the cornea, swelling of the cornea, a fixed semi-dilated pupil, nausea, vomiting, and episodes of blurred vision or seeing haloes.

      To confirm the diagnosis, tonometry is performed to measure the intraocular pressure. Normal pressure ranges from 10 to 21 mmHg, but in acute closed-angle glaucoma, it is often higher than 30 mmHg. Goldmann’s applanation tonometer is commonly used in hospitals for this purpose.

      Management of acute closed-angle glaucoma involves providing pain relief, such as morphine, and antiemetics if the patient is experiencing vomiting. Intravenous acetazolamide is administered to reduce intraocular pressure. Additionally, a topical miotic medication like pilocarpine is started about an hour after initiating other treatments to help constrict the pupil, as it may initially be paralyzed and unresponsive.

      Overall, acute closed-angle glaucoma is a medical emergency that requires prompt intervention to alleviate symptoms and prevent further damage to the eye.

    Correct

    • A 42-year-old woman presents with a painful swollen left big toe. The pain began this morning and is described as the most severe pain she has ever felt. It has progressively worsened over the past 8 hours. She is unable to wear socks or shoes and had to come to the appointment in open-toed sandals. The skin over the affected area appears red and shiny.

      What is the MOST likely diagnosis?

      Your Answer: Gout

      Explanation:

      The guidelines from the European League Against Rheumatism (EULAR) regarding the diagnosis of gout state that if a joint becomes swollen, tender, and red, and if acute pain develops in that joint over a period of 6-12 hours, it is highly likely to be a crystal arthropathy. Pseudogout is also a possibility, but it is much less likely. In this case, gout is the most probable diagnosis.

      The joint that is most commonly affected in acute gout is the first metatarsal-phalangeal joint, which accounts for 50-75% of cases.

      The main cause of gout is hyperuricaemia, and the clinical diagnosis can be confirmed by the presence of negatively birefringent crystals in the synovial fluid aspirate.

      For the treatment of acute gout attacks, NSAIDs or colchicine are generally used.

    • A 62 year old female presents to the emergency department with a three day history of nausea and upper abdominal pain. The patient is concerned as the nausea became severe enough to cause her to vomit today and she noticed dark blood in the vomitus. The patient takes simvastatin daily for high cholesterol and has recently been taking ibuprofen to treat knee pain. You are able to schedule her for an endoscopy today.

      Upon returning to the ED, you decide to conduct a risk assessment for upper gastrointestinal bleeding. Which of the following tools would be the most appropriate to use?

      Your Answer: Blatchford score

      Correct Answer: Full Rockall score

      Explanation:

      According to NICE guidelines, when evaluating patients with acute upper GI bleeding, it is recommended to use the Blatchford score during the initial assessment and the full Rockall score after endoscopy. The Rockall score is specifically designed to assess the risk of re-bleeding or death in these patients. If a patient’s post-endoscopic Rockall score is less than 3, they are considered to have a low risk of re-bleeding or death and may be eligible for early discharge.

      Further Reading:

      Upper gastrointestinal bleeding (UGIB) refers to the loss of blood from the gastrointestinal tract, occurring in the upper part of the digestive system. It can present as haematemesis (vomiting blood), coffee-ground emesis, bright red blood in the nasogastric tube, or melaena (black, tarry stools). UGIB can lead to significant hemodynamic compromise and is a major health burden, accounting for approximately 70,000 hospital admissions each year in the UK with a mortality rate of 10%.

      The causes of UGIB vary, with peptic ulcer disease being the most common cause, followed by gastritis/erosions, esophagitis, and other less common causes such as varices, Mallory Weiss tears, and malignancy. Swift assessment, hemodynamic resuscitation, and appropriate interventions are essential for the management of UGIB.

      Assessment of patients with UGIB should follow an ABCDE approach, and scoring systems such as the Glasgow-Blatchford bleeding score (GBS) and the Rockall score are recommended to risk stratify patients and determine the urgency of endoscopy. Transfusion may be necessary for patients with massive hemorrhage, and platelet transfusion, fresh frozen plasma (FFP), and prothrombin complex concentrate may be offered based on specific criteria.

      Endoscopy plays a crucial role in the management of UGIB. Unstable patients with severe acute UGIB should undergo endoscopy immediately after resuscitation, while all other patients should undergo endoscopy within 24 hours of admission. Endoscopic treatment of non-variceal bleeding may involve mechanical methods of hemostasis, thermal coagulation, or the use of fibrin or thrombin with adrenaline. Proton pump inhibitors should only be used after endoscopy.

      Variceal bleeding requires specific management, including the use of terlipressin and prophylactic antibiotics. Oesophageal varices can be treated with band ligation or transjugular intrahepatic portosystemic shunts (TIPS), while gastric varices may be treated with endoscopic injection of N-butyl-2-cyanoacrylate or TIPS if bleeding is not controlled.

      For patients taking NSAIDs, aspirin, or clopidogrel, low-dose aspirin can be continued once hemostasis is achieved, NSAIDs should be stopped in patients presenting with UGIB.

    • A 5-year-old boy presents with a rash. He has been complaining of a sore throat and headaches. His mother noticed the rash on his tummy this morning, and his skin feels a little like sandpaper to touch. The rash blanches to the touch. He has had high temperatures and a flushed face too. You suspect scarlet fever and offer them antibiotics. When they leave the hospital, you remember that this is a notifiable disease and that you should inform the Consultant in Communicable Disease Control.
      Within what time frame should you inform them about this case?

      Your Answer: Within 24 hours

      Correct Answer: Within 72 hours

      Explanation:

      If a case is not deemed urgent, it is necessary to inform the appropriate officer within a period of three days. However, if the case is suspected to be urgent, it is crucial to verbally notify the proper officer within a timeframe of 24 hours.

    Incorrect

    • You evaluate a 45-year-old male patient with a swollen and red right calf. His D-dimer levels are elevated, and you schedule an ultrasound scan which confirms the presence of a deep vein thrombosis (DVT) in his right calf. He has a history of a previous DVT and his INR today is 2.5.
      What is the MOST suitable course of action for management in this case?

      Your Answer: He should be started on a low molecular weight heparin

      Correct Answer: His target INR should be raised to 3.5

      Explanation:

      When managing a first episode of acute venous thromboembolism (VTE), it is recommended to start warfarin in combination with a parenteral anticoagulant, such as unfractionated heparin, low-molecular-weight heparin, or fondaparinux. The parental anticoagulant should be continued for a minimum of 5 days and ideally until the international normalized ratio (INR) is above 2 for at least 24 hours.

      To prevent the extension of the blood clot and recurrence in calf deep vein thrombosis (DVT), at least 6 weeks of anticoagulant therapy is necessary. For proximal DVT, a minimum of 3 months of anticoagulant therapy is required.

      For first episodes of VTE, the ideal target INR is 2.5. However, in cases where patients experience recurrent VTE while being anticoagulated within the therapeutic range, the target INR should be increased to 3.5.

    Correct

    • A 3 week old female is brought into the emergency department by concerned parents with intermittent vomiting. They inform you that for the past few days the baby has been projectile vomiting approximately 30 minutes after each feed. The parents are worried because the baby is not wetting her diaper as frequently as usual. Bowel movements are normal in consistency but less frequent. The baby has no fever, rashes, and her vital signs are normal. The parents inquire about the treatment plan for the most likely underlying diagnosis.

      What is the management approach for the most probable underlying condition?

      Your Answer: Advise the parents the child will likely require a pyloromyotomy

      Explanation:

      The most effective treatment for pyloric stenosis is pyloromyotomy, a surgical procedure. Before undergoing surgery, the patient should be rehydrated and any electrolyte imbalances should be corrected.

      Further Reading:

      Pyloric stenosis is a condition that primarily affects infants, characterized by the thickening of the muscles in the pylorus, leading to obstruction of the gastric outlet. It typically presents between the 3rd and 12th weeks of life, with recurrent projectile vomiting being the main symptom. The condition is more common in males, with a positive family history and being first-born being additional risk factors. Bottle-fed children and those delivered by c-section are also more likely to develop pyloric stenosis.

      Clinical features of pyloric stenosis include projectile vomiting, usually occurring about 30 minutes after a feed, as well as constipation and dehydration. A palpable mass in the upper abdomen, often described as like an olive, may also be present. The persistent vomiting can lead to electrolyte disturbances, such as hypochloremia, alkalosis, and mild hypokalemia.

      Ultrasound is the preferred diagnostic tool for confirming pyloric stenosis. It can reveal specific criteria, including a pyloric muscle thickness greater than 3 mm, a pylorus longitudinal length greater than 15-17 mm, a pyloric volume greater than 1.5 cm3, and a pyloric transverse diameter greater than 13 mm.

      The definitive treatment for pyloric stenosis is pyloromyotomy, a surgical procedure that involves making an incision in the thickened pyloric muscle to relieve the obstruction. Before surgery, it is important to correct any hypovolemia and electrolyte disturbances with intravenous fluids. Overall, pyloric stenosis is a relatively common condition in infants, but with prompt diagnosis and appropriate management, it can be effectively treated.

    • A 65-year-old patient presents with nausea and vomiting and decreased urine output. He has only passed a small amount of urine in the last day, and he has noticeable swelling in his ankles. His blood tests show a sudden increase in his creatinine levels in the last 2 days, leading to a diagnosis of acute kidney injury (AKI).
      Which of the following is NOT a cause of AKI that occurs after the kidneys?

      Your Answer:

      Correct Answer: Renal artery stenosis

      Explanation:

      Acute kidney injury (AKI), previously known as acute renal failure, is a sudden decline in kidney function. This results in the accumulation of urea and other waste products in the body and disrupts the balance of fluids and electrolytes. AKI can occur in individuals with previously normal kidney function or those with pre-existing kidney disease, known as acute-on-chronic kidney disease. It is a relatively common condition, with approximately 15% of adults admitted to hospitals in the UK developing AKI.

      The causes of AKI can be categorized into pre-renal, intrinsic renal, and post-renal factors. The majority of AKI cases that develop outside of healthcare settings are due to pre-renal causes, accounting for 90% of cases. These causes typically involve low blood pressure associated with conditions like sepsis and fluid depletion. Medications, particularly ACE inhibitors and NSAIDs, are also frequently implicated.

      Pre-renal:
      – Volume depletion (e.g., severe bleeding, excessive vomiting or diarrhea, burns)
      – Oedematous states (e.g., heart failure, liver cirrhosis, nephrotic syndrome)
      – Low blood pressure (e.g., cardiogenic shock, sepsis, anaphylaxis)
      – Cardiovascular conditions (e.g., severe heart failure, arrhythmias)
      – Renal hypoperfusion: NSAIDs, COX-2 inhibitors, ACE inhibitors or ARBs, abdominal aortic aneurysm
      – Renal artery stenosis
      – Hepatorenal syndrome

      Intrinsic renal:
      – Glomerular diseases (e.g., glomerulonephritis, thrombosis, hemolytic-uremic syndrome)
      – Tubular injury: acute tubular necrosis (ATN) following prolonged lack of blood supply
      – Acute interstitial nephritis due to drugs (e.g., NSAIDs), infection, or autoimmune diseases
      – Vascular diseases (e.g., vasculitis, polyarteritis nodosa, thrombotic microangiopathy, cholesterol emboli, renal vein thrombosis, malignant hypertension)
      – Eclampsia

      Post-renal:
      – Kidney stones
      – Blood clot
      – Papillary necrosis
      – Urethral stricture
      – Prostatic hypertrophy or malignancy
      – Bladder tumor

    Incorrect

    • You assess a 16 year old with an open fracture dislocation of the ankle after a motorcycle accident. The patient has been given nitrous oxide during transportation in the ambulance. The orthopedic surgeon on call is currently in the emergency department and recommends that the injury be promptly treated in the operating room. Which of the following statements about nitrous oxide is correct?

      Your Answer:

      Correct Answer: Nitrous oxide administration increases the fractional content of inhaled anaesthetic gases

      Explanation:

      The administration of nitrous oxide increases the amount of inhaled anaesthetic gases in the body through a phenomenon called the ‘second gas effect’. Nitrous oxide is much more soluble than nitrogen, with a solubility that is 20 to 30 times higher. When nitrous oxide is given, it causes a decrease in the volume of air in the alveoli. Additionally, nitrous oxide can enhance the absorption of other inhaled anaesthetic agents through the second gas effect. However, it is important to note that nitrous oxide alone cannot be used as the sole maintenance agent in anaesthesia.

      Further Reading:

      Entonox® is a mixture of 50% nitrous oxide and 50% oxygen that can be used for self-administration to reduce anxiety. It can also be used alongside other anesthesia agents. However, its mechanism of action for anxiety reduction is not fully understood. The Entonox bottles are typically identified by blue and white color-coded collars, but a new standard will replace these with dark blue shoulders in the future. It is important to note that Entonox alone cannot be used as the sole maintenance agent in anesthesia.

      One of the effects of nitrous oxide is the second-gas effect, where it speeds up the absorption of other inhaled anesthesia agents. Nitrous oxide enters the alveoli and diffuses into the blood, displacing nitrogen. This displacement causes the remaining alveolar gases to become more concentrated, increasing the fractional content of inhaled anesthesia gases and accelerating the uptake of volatile agents into the blood.

      However, when nitrous oxide administration is stopped, it can cause diffusion hypoxia. Nitrous oxide exits the blood and diffuses back into the alveoli, while nitrogen diffuses in the opposite direction. Nitrous oxide enters the alveoli much faster than nitrogen leaves, resulting in the dilution of oxygen within the alveoli. This can lead to diffusion hypoxia, where the oxygen concentration in the alveoli is diluted, potentially causing oxygen deprivation in patients breathing air.

      There are certain contraindications for using nitrous oxide, as it can expand in air-filled spaces. It should be avoided in conditions such as head injuries with intracranial air, pneumothorax, recent intraocular gas injection, and entrapped air following a recent underwater dive.

      Which SINGLE statement regarding this condition is true?

      Your Answer:

      Correct Answer: It is the third most common cause of dementia in the elderly

      Explanation:

      Dementia with Lewy bodies (DLB), also known as Lewy body dementia (LBD), is a progressive neurodegenerative condition that is closely linked to Parkinson’s disease (PD). It is the third most common cause of dementia in older individuals, following Alzheimer’s disease and vascular dementia.

      DLB is characterized by several clinical features, including the presence of Parkinsonism or co-existing PD, a gradual decline in cognitive function, fluctuations in cognition, alertness, and attention span, episodes of temporary loss of consciousness, recurrent falls, visual hallucinations, depression, and complex, systematized delusions. The level of cognitive impairment can vary from hour to hour and day to day.

      Pathologically, DLB is marked by the formation of abnormal protein collections called Lewy bodies within the cytoplasm of neurons. These intracellular protein collections share similar structural characteristics with the classic Lewy bodies observed in Parkinson’s disease.

      What is the MOST probable diagnosis in this case?

      Your Answer:

      Correct Answer: Testicular torsion

      Explanation:

      Testicular torsion is a condition where the spermatic cord twists, leading to a lack of blood flow to the testis. It is a surgical emergency and prompt action is necessary to save the testis. It is most commonly seen in individuals aged 15-30 years.

      Varicocele refers to the presence of varicose veins in the pampiniform plexus of the cord and scrotum. It is more frequently observed in the left testis and may be associated with infertility. This is believed to be due to the increased temperature caused by the varicose veins. Symptoms include a dull ache in the testis, which is often worse after exercise or at the end of the day. Standing examination can reveal the presence of Varicocele. Treatment is usually conservative, with surgery reserved for severe cases.

      Hydrocoele can occur at any age and is characterized by the accumulation of fluid in the tunica vaginalis. It presents as scrotal swelling, which can be palpated above. The surface of the hydrocoele is smooth and it can be transilluminated. The testis is contained within the swelling and cannot be felt separately. Primary or secondary causes can lead to hydrocoele, and in adults, an ultrasound is performed to rule out underlying pathology such as tumors. Conservative management is often sufficient unless the hydrocoele is large.

      Testicular cancer is the most common cancer in men aged 20-34 years. Awareness campaigns have emphasized the importance of self-examination for early detection. Risk factors include undescended testes, which increase the risk by 10-fold if bilateral. A previous history of testicular cancer carries a 4% risk of developing a second cancer. The usual presentation is a painless lump in the testis, which can also manifest as a secondary hydrocoele. Seminomas account for 60% of cases and are slow-growing, usually confined to the testis upon diagnosis. Stage 1 seminomas have a 98% 5-year survival rate. Teratomas, which can grow faster, make up 40% of cases and can occur within seminomas. Mixed type tumors are treated as teratomas due to their more aggressive nature. Surgical treatment, with or without chemotherapy and radiotherapy, is the primary approach.

      Epididymo-orchitis is inflammation of the testis and epididymis caused by infection.

    Incorrect

    • A 65-year-old patient with advanced metastatic bowel cancer is experiencing symptoms of bowel obstruction and is currently suffering from nausea and vomiting. The patient has been informed that she has only a few days left to live. Upon examination, her abdomen is found to be tender and distended.

      What is the most suitable course of action to address her nausea and vomiting in this situation?

      Your Answer:

      Correct Answer: Hyoscine butylbromide

      Explanation:

      According to NICE, hyoscine butylbromide is recommended as the initial medication for managing nausea and vomiting in individuals with obstructive bowel disorders who are in the last days of life. NICE provides guidance on how to handle these symptoms in the final days of life, which includes assessing the potential causes of nausea and vomiting in the dying person. This may involve considering factors such as certain medications, recent chemotherapy or radiotherapy, psychological causes, biochemical causes like hypercalcemia, raised intracranial pressure, gastrointestinal motility disorder, ileus, or bowel obstruction.

      It is important to discuss the available options for treating nausea and vomiting with the dying person and their loved ones. Non-pharmacological methods should also be considered when managing these symptoms in someone in the last days of life. When selecting medications for nausea and vomiting, factors such as the likely cause and reversibility of the symptoms, potential side effects (including sedation), other symptoms the person may be experiencing, and the desired balancing of effects when managing other symptoms should be taken into account. Additionally, compatibility and potential drug interactions with other medications the person is taking should be considered.

      For individuals in the last days of life with obstructive bowel disorders who have nausea or vomiting, hyoscine butylbromide is recommended as the first-line pharmacological treatment. If the symptoms do not improve within 24 hours of starting treatment with hyoscine butylbromide, octreotide may be considered as an alternative option.

    Incorrect

    • A 60-year-old woman comes in with intense pain and vision loss in her left eye. She has experienced multiple episodes of vomiting. Upon examination, there is noticeable redness around the left side of the cornea, and the left pupil is dilated and unresponsive to light.
      What is the most suitable initial treatment for this patient?

      Your Answer:

      Correct Answer: Intravenous acetazolamide

      Explanation:

      This patient has presented with acute closed-angle glaucoma, which is a serious eye condition requiring immediate medical attention. It occurs when the iris pushes forward and blocks the fluid access to the trabecular meshwork, leading to increased pressure within the eye and damage to the optic nerve.

      The main symptoms of acute closed-angle glaucoma include severe eye pain, decreased vision, redness around the cornea, swelling of the cornea, a fixed semi-dilated pupil, nausea, vomiting, and episodes of blurred vision or seeing haloes.

      To confirm the diagnosis, tonometry is performed to measure the intraocular pressure. Normal pressure ranges from 10 to 21 mmHg, but in acute closed-angle glaucoma, it is often higher than 30 mmHg. Goldmann’s applanation tonometer is commonly used in hospitals for this purpose.

      Management of acute closed-angle glaucoma involves providing pain relief, such as morphine, and antiemetics if the patient is experiencing vomiting. Intravenous acetazolamide is administered to reduce intraocular pressure. Additionally, a topical miotic medication like pilocarpine is started about an hour after initiating other treatments to help constrict the pupil, as it may initially be paralyzed and unresponsive.

      Overall, acute closed-angle glaucoma is a medical emergency that requires prompt intervention to alleviate symptoms and prevent further damage to the eye.

    Incorrect

    • A 65-year-old patient with advanced metastatic lung cancer is experiencing discomfort in his limbs and chest. Despite taking the maximum dosage of paracetamol, codeine phosphate, and ibuprofen regularly, his symptoms are no longer being adequately managed. You determine that it is necessary to discontinue the use of codeine phosphate and initiate stronger opioids.
      What would be the most suitable initial dosage regimen in this situation?

      Your Answer:

      Correct Answer: 20-30 mg oral morphine daily in divided doses

      Explanation:

      When starting treatment with strong opioids for pain relief in palliative care, it is recommended to offer patients regular oral sustained-release or oral immediate-release morphine, depending on their preference. In addition, provide rescue doses of oral immediate-release morphine for breakthrough pain. For patients without renal or hepatic comorbidities, a typical total daily starting dose schedule of 20-30 mg of oral morphine is suggested, along with 5 mg of oral immediate-release morphine for rescue doses during the titration phase. It is important to adjust the dose until a good balance is achieved between pain control and side effects. If this balance is not reached after a few dose adjustments, it is advisable to seek specialist advice. Patients should be reviewed frequently, especially during the titration phase. For patients with moderate to severe renal or hepatic impairment, it is recommended to consult a specialist before prescribing strong opioids.

      For maintenance therapy, oral sustained-release morphine is recommended as the first-line treatment for patients with advanced and progressive disease who require strong opioids. Transdermal patch formulations should not be routinely offered as first-line maintenance treatment unless oral opioids are not suitable. If pain remains inadequately controlled despite optimizing first-line maintenance treatment, it is important to review the analgesic strategy and consider seeking specialist advice.

      When it comes to breakthrough pain, oral immediate-release morphine should be offered as the first-line rescue medication for patients on maintenance oral morphine treatment. Fast-acting fentanyl should not be offered as the first-line rescue medication. If pain continues to be inadequately controlled despite optimizing treatment, it may be necessary to seek specialist advice.

      In cases where oral opioids are not suitable and analgesic requirements are stable, transdermal patches with the lowest acquisition cost can be considered. However, it is important to consult a specialist for guidance if needed. Similarly, for patients in whom oral opioids are not suitable and analgesic requirements are unstable, subcutaneous opioids with the lowest acquisition cost can be considered, with specialist advice if necessary.
