A nurse is caring for a client who has acute heart failure and received morphine IV 30 min ago. Which of the following findings should the nurse identify as an indication that the medication was effective?

Emesis of 250 mL

Increased respiratory rate to 26/min

Decreased anxiety

Decreased urinary output

Answer and Explanation

The Correct Answer is C

C. Morphine is a central nervous system depressant that can help decrease anxiety and relieve dyspnea in clients with acute heart failure. Therefore, a decrease in anxiety would indicate that the medication has been effective in achieving its intended outcome.
A. Emesis, or vomiting, is not an expected outcome of morphine administration in the context of acute heart failure.
B. While morphine can help alleviate dyspnea, an increased respiratory rate may indicate respiratory distress rather than effective symptom relief.
D. Morphine does not directly affect urinary output, and a decrease in urinary output may indicate other issues such as renal dysfunction or fluid overload.

Correct Answer is A

Explanation

A. Naloxone is a medication used as an opioid antagonist to reverse the effects of opioid overdose, including respiratory depression and hypotension. In this scenario, the client's symptoms suggest opioid-induced respiratory depression, making naloxone the appropriate choice to reverse the effects of morphine.
B. Protamine sulfate is used to reverse the anticoagulant effects of heparin, not for treating opioid-induced respiratory depression and hypotension.
C. Acetylcysteine is used as an antidote for acetaminophen (paracetamol) overdose, not for treating opioid-induced respiratory depression and hypotension.
D. Flumazenil is a medication used as a benzodiazepine antagonist to reverse the effects of benzodiazepine overdose or sedation.

A. Inability to smell B. Loss of peripheral vision C. Disequilibrium with movement D. Deviation of the tongue from midline

Correct Answer is C

Explanation

A. The olfactory nerve (cranial nerve I) is responsible for the sense of smell.
B. Loss of peripheral vision is typically associated with impairment of the optic nerve (cranial nerve II), which is responsible for vision.
