Question 5 of 5
The use of morphine is contraindicated in all the following conditions EXCEPT:
Correct Answer: C
Rationale: Morphine is contraindicated in conditions where its effects exacerbate risks. In head injuries (choice A), it masks neurological signs (e.g., pupil changes) and raises intracranial pressure via CO2 retention from respiratory depression. In bronchial asthma (choice B), respiratory depression worsens hypoxemia. In myxoedema (choice D), slowed metabolism increases sensitivity to CNS depression. However, in acute left ventricular failure (choice C), morphine is beneficial, reducing preload and anxiety in pulmonary edema, improving oxygenation. This exception reflects its therapeutic role in cardiac emergencies, contrasting with contraindications where CNS or respiratory depression is detrimental. Understanding these nuances guides safe morphine use.
