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.

Answer and Explanation

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 A

Explanation

Epinephrine (adrenaline) is the first-line treatment for anaphylaxis, a severe and potentially life-threatening allergic reaction. Epinephrine works by reducing the body’s allergic response and improving the breathing and circulation of the client. Epinephrine should be given as soon as possible after the onset of anaphylaxis symptoms, using an auto-injector device if available.

Choice B is wrong because replacing the infusion with 0.9% sodium chloride (normal saline) is not enough to treat anaphylaxis. Normal saline can help maintain the blood pressure and hydration of the client, but it does not reverse the allergic reaction or improve the breathing of the client. Normal saline can be given after epinephrine, but not before or instead of it.

Choice C is wrong because giving diphenhydramine IM is not enough to treat anaphylaxis. Diphenhydramine is an antihistamine that can help relieve some of the symptoms of anaphylaxis, such as itching and hives, but it works too slowly and does not address the more serious effects of anaphylaxis on the breathing and circulation of the client. Diphenhydramine can be given after epinephrine, but not before or instead of it.

Choice D is wrong because elevating the client's legs and feet is not enough to treat anaphylaxis. Elevating the legs and feet can help increase the blood flow to the vital organs, but it does not reverse the allergic reaction or improve the breathing of the client. Elevating the legs and feet can be done after epinephrine, but not before or instead of it.

A. The potassium infusion rate is too rapid. B. Another formulation of potassium should be given IV. C. Potassium chloride should be diluted in dextrose 5% in water. D. The client should be treated by giving potassium by IV bolus.

Correct Answer is A

Explanation

According to various guidelines12345, the recommended rate of intravenous potassium replacement is 10-20 mEq/h with continuous ECG monitoring. The maximum rate is 40 mEq/h in emergency situations. The prescription given by the provider exceeds this limit and could cause cardiac arrhythmias or hyperkalemia.

Choice B is wrong because potassium chloride is a common and appropriate formulation of potassium for intravenous administration.

Choice C is wrong because potassium chloride should not be diluted in dextrose 5% in water, as this could cause hyperglycemia or osmotic diuresis.

Choice D is wrong because potassium should never be given by IV bolus, as this could cause cardiac arrest or tissue necrosis.
