Question

Quizplus · Accepted Answer

Respiratory depression is the most significant adverse effect of morphine sulfate administration. Morphine can suppress the breathing center in the brainstem, leading to respiratory depression, and in severe cases, respiratory arrest. The nurse should monitor the patient's respiratory rate, depth, and effort frequently and assess oxygen saturation levels. If respiratory depression occurs, the nurse should immediately stop the infusion and administer naloxone, a narcotic antagonist, as ordered. Option A is incorrect because morphine sulfate can cause an initial increase in heart rate followed by bradycardia. Option B is incorrect as muscle weakness is not a frequent adverse effect of morphine sulfate. Option C is incorrect as morphine sulfate does not have a direct effect on urine output.
