1. Which lab value is essential for a patient receiving warfarin therapy?

Correct answer: A

Rationale: The correct answer is to monitor the INR (International Normalized Ratio) for a patient receiving warfarin therapy. INR monitoring is crucial to assess the effectiveness of warfarin in preventing blood clots while minimizing the risk of bleeding. Monitoring sodium levels (choice B), potassium levels (choice C), or platelet count (choice D) is not specifically essential for patients on warfarin therapy and does not provide direct information on the drug's anticoagulant effects.

2. A nurse is reviewing the medical record of a client who has a new prescription for spironolactone. Which of the following findings should the nurse report to the provider?

Correct answer: D

Rationale: A serum creatinine level of 3.0 mg/dL indicates impaired kidney function, which is a concern when prescribing spironolactone as it can further affect renal function. Elevated serum creatinine levels may suggest decreased renal clearance of spironolactone, leading to potential toxicity. Potassium, calcium, and magnesium levels are within normal ranges and not directly related to spironolactone therapy. Therefore, the nurse should report the elevated serum creatinine level to the provider for further evaluation and possible dosage adjustment.

3. What is the appropriate action when a patient experiences an allergic reaction to a medication?

Correct answer: A

Rationale: The correct answer is to administer epinephrine. Epinephrine is the first-line treatment for a severe allergic reaction as it helps to constrict blood vessels, increase heart rate, and open airways, thereby improving breathing and circulation. Discontinuing the medication may not be sufficient to manage a severe allergic reaction as the allergen is already in the patient's system. Corticosteroids and antihistamines can be considered as complementary treatments but are not the primary immediate intervention required for a severe allergic reaction.

4. A nurse is teaching a client who has hypertension about managing blood pressure. Which of the following statements should the nurse make?

Correct answer: C

Rationale: The correct statement is C: 'Exercise for at least 30 minutes most days of the week.' Regular exercise is essential in managing blood pressure as it helps improve cardiovascular health. Choice A is incorrect as increasing red meat intake can be detrimental due to its high saturated fat content, which can negatively impact blood pressure. Choice B is not directly related to managing blood pressure unless the medication interacts negatively with alcohol. Choice D, limiting fluid intake to 3 liters per day, is not a general recommendation for managing blood pressure unless specifically advised by a healthcare provider.

5. A client with a new diagnosis of diabetes mellitus is being taught about foot care by a nurse. Which of the following instructions should the nurse include?

Correct answer: B

Rationale: The correct answer is B: 'Trim your toenails straight across to prevent injury.' In clients with diabetes, trimming toenails straight across is essential to prevent ingrown toenails and injury. Choice A is incorrect because soaking feet in warm water can lead to dryness, which is not recommended for diabetic foot care. Choice C is incorrect as applying lotion between the toes can create excess moisture, increasing the risk of fungal infections. Choice D is incorrect because although cotton socks are recommended, the primary purpose is to prevent moisture buildup, not specifically to keep the feet dry.
