Nursing Elites

1. A client with atrial fibrillation is receiving warfarin (Coumadin). The nurse should monitor which laboratory test to determine the effectiveness of the therapy?

• A. Prothrombin time (PT) and international normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Complete blood count (CBC)
• D. Fibrinogen level

Correct answer: A

Rationale: To monitor the effectiveness of warfarin therapy in a client with atrial fibrillation, the nurse should assess the Prothrombin time (PT) and international normalized ratio (INR) levels. These tests help determine the clotting ability of the blood and ensure that the client's anticoagulation levels are within the therapeutic range, reducing the risk of bleeding or clotting complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy. Complete blood count (CBC) (Choice C) provides information about the cellular components of blood but does not directly assess the effectiveness of warfarin therapy. Fibrinogen level (Choice D) is not typically used to monitor warfarin therapy; it reflects the level of fibrinogen in the blood, which is involved in the clotting process.

2. The nurse is preparing to administer an intravenous dose of potassium chloride to a client with hypokalemia. The nurse should monitor for which potential complication?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hypernatremia
• D. Hypercalcemia

Correct answer: A

Rationale: When administering potassium chloride to a client with hypokalemia, the nurse should monitor for hyperkalemia. Potassium chloride supplementation aims to increase potassium levels in individuals with hypokalemia. However, excessive administration can lead to hyperkalemia, which can be a serious and potentially life-threatening complication. Monitoring potassium levels is crucial to prevent this adverse outcome. Hypokalemia (Choice B) is the condition being treated, so it is not a complication of treatment. Hypernatremia (Choice C) refers to high sodium levels and is not directly related to the administration of potassium chloride. Hypercalcemia (Choice D) is an elevated calcium level and is not a common complication associated with potassium chloride administration in hypokalemia.

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

• A. Take the medication with food.
• B. Monitor for signs of hyperglycemia.
• C. Increase your fluid intake.
• D. Expect a sweet taste in your mouth.

Correct answer: C

Rationale: The correct instruction for a client starting metformin is to increase fluid intake. Metformin commonly causes gastrointestinal discomfort, and increasing fluid intake can help alleviate this side effect. Instructing the client to take the medication with food (Choice A) rather than on an empty stomach is recommended to reduce gastrointestinal side effects. Monitoring for signs of hyperglycemia (Choice B) is not directly related to metformin but rather to low blood sugar. Expecting a sweet taste in the mouth (Choice D) is not a common side effect of metformin.

4. An ambulatory clinic nurse is interviewing a client who is complaining of flu-like symptoms. The client suddenly develops chest pain. Which question best assists the nurse in discriminating pain caused by a non-cardiac problem?

• A. Can you describe the pain to me?
• B. Have you ever experienced this pain before?
• C. Does the pain get worse when you breathe in?
• D. Can you rate the pain on a scale of 1 to 10, with 10 being the worst?

Correct answer: C

Rationale: The correct answer is C. Pain that worsens with breathing in can indicate pleuritic chest pain, which is non-cardiac in nature. This specific question helps in differentiating non-cardiac causes from cardiac causes of chest pain, as cardiac pain typically does not worsen with breathing. Choices A, B, and D are less specific in discriminating between cardiac and non-cardiac chest pain.

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

• A. Take the medication with food.
• B. Monitor heart rate daily.
• C. Increase intake of potassium-rich foods.
• D. Avoid consuming dairy products.

Correct answer: B

Rationale: The correct answer is to monitor heart rate daily. Propranolol is a beta-blocker that can lower heart rate and blood pressure, so it is essential to monitor heart rate regularly to detect any signs of bradycardia, a potential side effect of the medication. Choice A is incorrect because propranolol can be taken with or without food. Choice C is incorrect as increasing potassium-rich foods is not specifically required with propranolol. Choice D is also incorrect as there is no need to avoid consuming dairy products with propranolol.
