A nurse is administering naloxone to a client who has developed an adverse reaction to morphine.
The nurse should identify which of the following findings is a therapeutic effect of naloxone?
Decreased blood pressure.
Decreased nausea.
Increased respiratory rate.
Increased pain relief.
The Correct Answer is C
A therapeutic effect of naloxone is the reversal of opioid-induced respiratory depression, which is one of the most dangerous complications of opioid overdose. Naloxone works by binding to opioid receptors, displacing opioids, and restoring normal respiratory drive. An increase in respiratory rate after administration indicates that naloxone is effective.
Choice A is wrong because decreased blood pressure is not a therapeutic effect of naloxone.
In fact, naloxone can cause hypertension (high blood pressure) as a side effect due to opioid withdrawal.
Choice B is wrong because decreased nausea is not a therapeutic effect of naloxone. Nausea is a common side effect of morphine, but naloxone does not affect it directly.
Naloxone can actually cause nausea and vomiting as a side effect due to opioid withdrawal.
Choice D is wrong because increased pain relief is not a therapeutic effect of naloxone.
Pain relief is a desired effect of morphine, but naloxone antagonizes it by blocking the opioid receptors.
Naloxone can cause pain and discomfort as a side effect due to opioid withdrawal.

Correct Answer is B
Explanation
Hot flashes are a common side effect of tamoxifen, which is hormone therapy for breast cancer that blocks the action of estrogen.
Tamoxifen can cause menopause-like symptoms in women, such as irregular or missing periods, vaginal discharge or bleeding, and mood changes. Choice A is wrong because tinnitus (ringing in the ears) is not a known side effect of tamoxifen.
Choice C is wrong because urinary frequency (needing to urinate more often) is not a known side effect of tamoxifen.
Choice D is wrong because constipation (difficulty passing stools) is not a known side effect of tamoxifen.
