Question

a nurse should identify that dextromethorphan can have which of the following effects when combined with morphine? reduced antitussive effect of dextromethorphan potentiation of depression of cns actions increased renal reabsorption of the dextromethorphan delayed analgesic effect of the opioid

Explanation:

Dextromethorphan and morphine both have central nervous system (CNS) depressant properties. When combined, their depressive effects on the CNS (such as sedation, respiratory depression) are amplified, a phenomenon called potentiation. The other options are incorrect: dextromethorphan's antitussive effect is not reduced, renal reabsorption is not increased, and the opioid's analgesic effect is not delayed by this combination.

Answer:

Potentiation of depression of CNS actions
