Nursing Elites

1. A client with active tuberculosis asks why he must take four different medications. Which of the following responses should the nurse make?

• A. Four medications decrease the risk of a severe allergic reaction.
• B. Four medications reduce the chance that the bacteria will become resistant.
• C. Four medications reduce the risk of adverse reactions.
• D. Four medications decrease the chance of having a positive tuberculin skin test.

Correct answer: B

Rationale: The correct answer is B. When treating tuberculosis, using a combination of medications is crucial to reduce the risk of bacteria developing resistance to any single drug. This approach helps prevent treatment failure and ensures successful treatment outcomes. Choice A is incorrect because the primary purpose of using multiple medications is not related to allergic reactions. Choice C is incorrect as the risk reduction is mainly focused on bacterial resistance rather than adverse reactions. Choice D is not relevant as the purpose of taking multiple medications is not to affect the tuberculin skin test results.

2. Which of the following drugs is associated with hepatitis as a reaction?

• A. Valproic acid
• B. Quinidine
• C. Isoniazid
• D. Ethosuximide

Correct answer: C

Rationale: Hepatitis is a known side effect of isoniazid. It is important to monitor patients on isoniazid for signs of liver damage, including hepatitis, as part of their treatment regimen for tuberculosis.

3. A client is starting a new prescription for levothyroxine. Which of the following instructions should the nurse include?

• A. Take the medication at bedtime.
• B. Take the medication with food.
• C. Take the medication first thing in the morning on an empty stomach.
• D. Take the medication with a full glass of milk.

Correct answer: C

Rationale: The correct instruction for taking levothyroxine is to take the medication first thing in the morning on an empty stomach. This timing is important for optimal absorption of the medication. Taking levothyroxine with food or at bedtime can interfere with its absorption. Milk and other foods, as well as certain medications, can reduce the effectiveness of levothyroxine by interfering with its absorption, so it should be taken separately from these items. Therefore, the correct choice is to take the medication first thing in the morning on an empty stomach.

4. A client has a new prescription for Warfarin. The nurse should identify that the concurrent use of which of the following medications increases the client's risk of bleeding?

• A. Vitamin K
• B. Calcium carbonate
• C. Acetaminophen
• D. Ranitidine

Correct answer: C

Rationale: The correct answer is Acetaminophen (Choice C). Acetaminophen, especially in high doses, can increase the risk of bleeding in clients taking Warfarin. It can potentiate the anticoagulant effect of Warfarin, leading to an increased risk of bleeding. Vitamin K (Choice A) is actually used to reverse the effects of Warfarin in case of over-anticoagulation, so it does not increase the risk of bleeding. Calcium carbonate (Choice B) and Ranitidine (Choice D) do not significantly interact with Warfarin to increase the risk of bleeding.

5. When teaching a client about a new prescription for Celecoxib, which of the following information should the nurse include?

• A. Increases the risk for a myocardial infarction
• B. Decreases the risk of stroke
• C. Inhibits COX-1
• D. Increases platelet aggregation

Correct answer: A

Rationale: The nurse should educate the client that taking Celecoxib increases the risk of a myocardial infarction due to its suppression of vasodilation. Celecoxib belongs to the class of NSAIDs known to have cardiovascular risks, including an increased risk of heart attacks. Choice B is incorrect because Celecoxib does not decrease the risk of stroke. Choice C is incorrect because Celecoxib selectively inhibits COX-2 rather than COX-1. Choice D is incorrect because Celecoxib does not increase platelet aggregation; in fact, it inhibits platelet aggregation.
