Final answer:
Morphine is indeed to be used with caution among patients with UA/NSTEMI, due to a possible connection to increased mortality, stemming from its effects on antiplatelet agent absorption and potential for causing hypotension. (option a is the correct answer)
Step-by-step explanation:
Morphine should indeed be used with caution in patients with unstable angina (UA)/NSTEMI due to an association with increased mortality. Morphine has been a cornerstone treatment in acute coronary syndromes (ACS) for its pain-relieving properties and ability to reduce the workload of the heart.
Recent studies suggest that the use of morphine in this patient population may be associated with delayed absorption of oral antiplatelet agents, potential for hypotension, and adverse outcomes. Hence, while morphine can provide valuable symptomatic relief, its use must be weighed against these potential risks, especially in the context of unstable angina or non-ST-segment elevation myocardial infarction (NSTEMI).
The cautious use of morphine in unstable angina and NSTEMI is supported by considerations of potential adverse effects on hemodynamics and delayed initiation of essential antiplatelet therapy, emphasizing the need for individualized patient assessment in clinical decision-making.
