A nurse is caring for a client who is receiving morphine for pain. Which of the following findings indicates that the client is experiencing an adverse effect of the medication?

Choice A Reason: Hypertension (high blood pressure) is not a common adverse effect of morphine. Opioid medications are more likely to cause hypotension (low blood pressure). Choice B Reason: Lacrimation (excessive tearing) is not a typical adverse effect of morphine. Opioids can cause dry mouth and decreased tear production. Choice C Reason: Tachycardia (rapid heart rate) is not a common adverse effect of morphine. Morphine and other opioids are more likely to cause bradycardia (slow heart rate) or a decrease in heart rate. Choice D Reason: Urinary retention is an adverse effect associated with opioid medications like morphine. Opioids can cause relaxation of smooth muscles, including those in the urinary bladder, which can lead to difficulty or inability to urinate.
