Correct Answer is A

Explanation

The nurse should advise the client to avoid taking St. John’s Wort with sertraline because it can increase the risk of a rare but serious condition called serotonin syndrome. Serotonin syndrome can cause symptoms such as confusion, hallucination, seizure, extreme changes in blood pressure, increased heart rate, fever, excessive sweating, shivering or shaking, blurred vision, muscle spasm or stiffness, tremor, incoordination, stomach cramp, nausea, vomiting, and diarrhoea.

Choice B. Black cohosh is wrong because it is a herbal supplement that is used to treat menopausal symptoms and has no known interaction with sertraline.

Choice C. Coenzyme Q is wrong because it is a natural substance that is involved in energy production and has no known interaction with sertraline.

Choice D. Ginger root is wrong because it is a spice that is used to treat nausea and has no known interaction with sertraline.

A. Limit foods containing tyramine. B. Decrease your daily sodium intake. C. Take this medication 2 hours before a meal. D. Report swelling of the feet to your provider.

Correct Answer is D

Explanation

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.
