MRCP2-3750
A 65-year-old man has been admitted to the urology department due to difficulty passing urine and back pain. A bladder scan revealed 980 mls of urine in his bladder, and he was catheterized by the admitting doctor, which resulted in haematuria. The patient has a medical history of metastatic prostate cancer, hypertension, hypercholesterolemia, hypothyroidism, atrial fibrillation, and a previous NSTEMI. He is currently taking warfarin and modified-release morphine 30 mg every 12 hours.
The urology consultant has recommended inserting a 3-way catheter if the haematuria persists and referring the patient to the palliative care team for pain management. The palliative care specialist has suggested increasing the modified-release morphine to 45 mg every 12 hours.
What is the appropriate dosage of immediate-release morphine for the patient’s breakthrough pain?
