A female client with mild depression reports to the nurse recently starting St. John's wort. Which information provided by the client requires further instruction?
Hard candy can be used for a dry mouth.
Another form of contraception is not needed.
Insomnia may occur while taking the medication.
Sensitivity to the sun can develop.
The Correct Answer is B
Choice A reason: Hard candy can be used for a dry mouth, which is a common side effect of St. John's wort.
Choice B reason: Another form of contraception is needed, because St. John's wort can reduce the effectiveness of oral contraceptives and increase the risk of unplanned pregnancy. This information requires further instruction from the nurse.

Choice C reason: Insomnia may occur while taking the medication, which is another possible side effect of St. John's wort. The client should be advised to take the medication in the morning or afternoon, and avoid caffeine and alcohol.
Choice D reason: Sensitivity to the sun can develop, which is a rare but serious side effect of St. John's wort. The client should be instructed to wear sunscreen and protective clothing when exposed to sunlight.

Correct Answer is A
Explanation
Choice A reason: Eliminating use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, is an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that stabilizes mood and prevents manic episodes. NSAIDs can increase the blood levels of lithium and cause toxicity, which can manifest as nausea, vomiting, tremors, confusion, or seizures.
Choice B reason: Monitoring blood glucose levels daily is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not affect the blood sugar levels or the risk of diabetes. Blood glucose levels may be important for the general health of the client, but they are not related to lithium therapy.
Choice C reason: Notifying healthcare provider prior to dental procedures is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not interact with local anesthetics or antibiotics that may be used during dental procedures. However, the client should inform the dentist about their medical history and medications, as a precaution.
Choice D reason: Avoiding consuming all foods that contain iodine is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not interfere with the thyroid function or the metabolism of iodine. Iodine is an essential nutrient that is found in many foods, such as seafood, dairy products, eggs, and iodized salt. Avoiding iodine can cause deficiency and lead to goiter or hypothyroidism.
Correct Answer is D
Explanation
Choice A reason: Increasing intake of fluids and high protein foods is not an instruction that the nurse should provide to the client who is taking baclofen, which is a medication that relaxes skeletal muscles and reduces spasticity. Fluids and high protein foods do not affect the action or side effects of baclofen.
Choice B reason: Stopping taking the medication immediately is not an instruction that the nurse should provide to the client who is taking baclofen, which is a medication that should be tapered off gradually under medical supervision. Abrupt withdrawal of baclofen can cause serious complications, such as seizures, hallucinations, and increased spasticity.
Choice C reason: Obtaining transportation to the emergency department is not an instruction that the nurse should provide to the client who is taking baclofen, which is a medication that can cause mild and transient side effects, such as fatigue and dizziness. These side effects are not life-threatening and usually subside as the body adjusts to the medication.
Choice D reason: Avoiding hazardous activities until symptoms subside is an instruction that the nurse should provide to the client who is taking baclofen, which is a medication that can impair the ability to drive, operate machinery, or perform other tasks that require alertness and coordination. The client should be advised to exercise caution and avoid activities that could result in injury until they are no longer experiencing fatigue and dizziness.
