A client in the intensive care unit has a presentation of pinpoint pupils, respiratory depression, and coma after overdosing on morphine sulfate (Astramorph). Which of the following is the appropriate complication based on the client's presentation?

The correct answer is A: Opioid toxicity triad. Pinpoint pupils, respiratory depression, and coma are classic signs of opioid toxicity. Pinpoint pupils result from the inhibition of the parasympathetic response, leading to miosis. Respiratory depression is a common side effect of opioid overdose due to the suppression of the respiratory center in the brainstem. Coma may occur as a severe consequence of central nervous system depression. Therefore, the presentation of pinpoint pupils, respiratory depression, and coma align with the opioid toxicity triad.
Incorrect Choices: B: Orthostatic hypotension is not typically associated with morphine overdose. C: Hypertension is not a common complication of morphine overdose. D: Abstinence syndrome occurs when a person dependent on opioids suddenly stops or reduces their use, not as a complication of acute overdose.
