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?

This is because swelling of the feet can be a sign of lithium toxicity, which is a serious condition that can occur when the level of lithium in the blood is too high. Lithium toxicity can cause confusion, irregular heartbeat, muscle weakness, and kidney problems. Therefore, the client should report any signs of lithium toxicity to their provider as soon as possible.

Choice A is wrong because limiting foods containing tyramine is not necessary for clients taking lithium. Tyramine is a substance found in some foods that can interact with certain antidepressants called monoamine oxidase inhibitors (MAOIs), but not with lithium.

Choice B is wrong because decreasing the daily sodium intake can actually increase the risk of lithium toxicity.

Sodium helps to regulate the amount of lithium in the body, so if the sodium level is low, the lithium level can rise too high.

The client should maintain a normal sodium intake and drink enough fluids while taking lithium.

Choice C is wrong because taking this medication 2 hours before a meal is not required for clients taking lithium.

Lithium can be taken with or without food, but it should be taken at the same time each day to keep a steady level in the blood.

Taking lithium 2 hours before a meal may cause stomach upset, which is a common side effect of lithium.

Distended neck veins are a sign of increased central venous pressure, which can result from fluid volume excess. Fluid volume excess can also cause edema, crackles in the lungs, and increased blood pressure.

Choice A is wrong because decreased bowel sounds are not related to fluid volume excess.

Decreased bowel sounds can indicate ileus, obstruction, or peritonitis. Choice B is wrong because bilateral muscle weakness is not a sign of fluid volume excess.

Bilateral muscle weakness can be caused by electrolyte imbalances, neuromuscular disorders, or stroke.

Choice C is wrong because thready pulse is a sign of fluid volume deficit, not excess.

Thready pulse indicates poor perfusion and low cardiac output, which can result from dehydration, hemorrhage, or shock.
