Which statement about morphine use is incorrect?

• A. It may cause dizziness due to lowered blood pressure
• B. It is safe to drive after taking morphine
• C. It should be avoided with alcohol or CNS depressants
• D. It can cause respiratory distress; report if it occurs

Answer: (B)

Morphine is a potent central nervous system depressant that can impair alertness, coordination, and reaction time. Because of its sedating effects, it can make activities like driving unsafe until you know how it affects you. In addition, morphine can cause dizziness, especially with blood pressure changes, and it can slow or shallow breathing (respiratory depression) in some people, which is why any signs of breathing difficulty should be reported promptly. It also interacts with alcohol and other CNS depressants, increasing the risk of sedation and overdose. Given these effects, the statement that it is safe to drive after taking morphine is not correct. The other statements reflect known, clinically relevant risks and cautions with morphine use.
