The nurse is preparing to administer morphine IV to a client who has been diagnosed with multiple trauma. Before administering the morphine, what common adverse effect should the nurse inform the client about?

Rationale: A. Paresthesia in lower extremities: Paresthesia is not a typical adverse effect of morphine. If it occurs, it may be due to nerve damage or another underlying issue rather than the opioid itself. B. Occipital headache: Headache is not commonly associated with morphine administration. If a headache does occur, it may be due to other causes like trauma, dehydration, or positional changes rather than the opioid. C. Photophobia: Photophobia is more often linked to neurological or ophthalmologic conditions such as migraines or meningitis. It is not a recognized adverse effect of morphine. D. Drowsiness: Drowsiness or sedation is a common and expected side effect of morphine due to its central nervous system depressant effects. Clients should be warned about this to avoid injury and understand what to expect after administration.
