Question 1 of 5
The patient's respirations dropped from 14 breaths/minute to 8 breaths/minute after receiving a large dose of morphine. Which term accurately describes the patient's reaction to the morphine?
Correct Answer: A
Rationale: The correct answer is A:
Toxic. The decrease in respirations from 14 to 8 breaths/minute after a large dose of morphine indicates an adverse reaction known as respiratory depression, which is a toxic effect of morphine. Morphine can depress the respiratory center in the brainstem, leading to a decrease in breathing rate.
Choice B, allergic reaction, involves the immune system and is not related to the respiratory depression caused by morphine.
Choice C, idiosyncratic reaction, refers to an individual's unique and unpredictable response to a medication, which does not specifically address the toxic effect seen here.
Choice D, therapeutic, would not be appropriate as the decreased respiratory rate is not a desired therapeutic outcome.
