1. A client has a new prescription for Warfarin. Which of the following statements by the client indicates a need for further teaching?

Correct answer: C

Rationale: The correct answer is C because Warfarin interacts with vitamin K, not potassium. Therefore, the client needs to be cautious with foods high in vitamin K, such as green leafy vegetables, rather than foods high in potassium. Choices A, B, and D are correct statements regarding Warfarin therapy and do not indicate a need for further teaching.

2. A healthcare provider is caring for a group of clients who are not protected against Varicella. The healthcare provider should prepare to administer the Varicella vaccine at this time to which of the following clients?

Correct answer: D

Rationale: The correct answer is the 32-year-old man who has essential hypertension. Individuals who did not receive two doses of the varicella vaccine earlier in life should be immunized. Essential hypertension is not a contraindication for this vaccine, making it safe to administer to this client. Choice A is incorrect because administering the Varicella vaccine is contraindicated during pregnancy due to the risk of transmission to the fetus. Choice B is incorrect because a severe allergy to neomycin is a contraindication to the Varicella vaccine, which contains a trace amount of neomycin. Choice C is incorrect because the Varicella vaccine is not recommended for infants under 12 months of age.

3. A client has a new prescription for Omeprazole. Which of the following instructions should the nurse include?

Correct answer: A

Rationale: The correct answer is A: 'Take this medication before meals.' Omeprazole is a proton pump inhibitor that is most effective in reducing stomach acid production when taken before meals. This timing helps the medication work optimally by inhibiting acid secretion that occurs in response to food intake. Choice B ('Take this medication with food') is incorrect because Omeprazole should be taken before meals. Choice C ('Take this medication at bedtime') is incorrect as the optimal timing is before meals, not at bedtime. Choice D ('Take this medication with antacids') is incorrect because Omeprazole should not be taken with antacids as they can interfere with its absorption.

4. A client has a new prescription for Lovastatin. Which of the following instructions should be included?

Correct answer: C

Rationale: Lovastatin should be taken at bedtime because cholesterol production in the liver is highest at night, making the medication more effective in reducing cholesterol levels. By taking it at bedtime, the medication aligns with the body's natural rhythm of cholesterol synthesis, optimizing its therapeutic effects.

5. A client has a new prescription for Iron supplements. Which of the following instructions should be included in the teaching?

Correct answer: C

Rationale: The correct answer is to increase fiber intake to prevent constipation when taking iron supplements. Iron supplements can lead to constipation as a common side effect. Increasing fiber intake helps promote healthy bowel movements and counteracts the constipating effects of iron. Choice A is incorrect because iron absorption is hindered by calcium found in milk. Choice B is incorrect as orange juice enhances iron absorption due to its vitamin C content. Choice D is incorrect as iron supplements can cause stools to appear dark, not bright red.
