Nursing Elites

1. The healthcare provider assesses a client who has been prescribed furosemide (Lasix) for cardiac disease. Which electrocardiographic change would be a concern for a client taking a diuretic?

• A. Tall, spiked T waves
• B. A prolonged QT interval
• C. A widening QRS complex
• D. Presence of a U wave

Correct answer: D

Rationale: The presence of a U wave is often associated with hypokalemia, a possible side effect of diuretic therapy like furosemide. Hypokalemia can lead to U wave formation on an electrocardiogram, making the presence of U waves a concerning finding in clients taking diuretics. Tall, spiked T waves are typically seen in hyperkalemia, not hypokalemia. A prolonged QT interval is more commonly associated with conditions like Long QT syndrome or certain medications, not specifically with diuretics. A widening QRS complex is usually seen in conditions affecting the conduction system of the heart, such as bundle branch blocks, rather than being directly related to diuretic use.

2. A healthcare provider is assessing a client who has been taking lisinopril. Which of the following findings should the provider report?

• A. Dry cough
• B. Hyperkalemia
• C. Elevated blood pressure
• D. Increased appetite

Correct answer: A

Rationale: The correct answer is A: Dry cough. A dry cough is a common side effect of lisinopril. It is essential to report this to the healthcare provider as it may indicate the need to discontinue the medication to prevent further complications such as angioedema or cough that can persist for weeks to months after stopping the medication. Choice B, hyperkalemia, is not typically associated with lisinopril use; instead, it is a possible side effect of medications like potassium-sparing diuretics. Choice C, elevated blood pressure, would not be a concerning finding as lisinopril is often prescribed to lower blood pressure. Choice D, increased appetite, is not a common side effect of lisinopril and would not typically warrant immediate reporting.

3. A client with known coronary artery disease (CAD) begins to experience chest pain while getting out of bed. What action should the nurse take?

• A. Obtain a prescription for pain medication.
• B. Have the client stop and lie back down in bed.
• C. Report the complaint to the healthcare provider.
• D. Instruct the client to continue getting out of bed and into a chair.

Correct answer: B

Rationale: When a client with CAD experiences chest pain, it indicates myocardial ischemia. The nurse should have the client stop the activity and lie back down in bed to reduce the heart's oxygen demand, decrease myocardial workload, and prevent further ischemia. This action helps in improving blood flow to the heart and can potentially alleviate the chest pain. Option A is incorrect as pain medication should not be the initial action for chest pain in CAD. Option C is incorrect because the nurse should first intervene directly to address the chest pain. Option D is incorrect as continuing the activity can worsen the myocardial ischemia and chest pain.

4. A client's serum calcium level is 7.9 mg/dL. The nurse is immediately concerned, knowing that this level could lead to which complication?

• A. Stroke
• B. Cardiac arrest
• C. High blood pressure
• D. Urinary stone formation

Correct answer: B

Rationale: A serum calcium level below normal (hypocalcemia) can lead to cardiac arrhythmias and potentially cardiac arrest. Calcium plays a crucial role in cardiac muscle contractility, and low levels can disrupt normal heart function, potentially leading to fatal arrhythmias and cardiac arrest. Choices A, C, and D are incorrect as hypocalcemia is not directly associated with stroke, high blood pressure, or urinary stone formation. The immediate concern with low serum calcium levels is the risk of cardiac complications.

5. A client with atrial fibrillation is receiving warfarin (Coumadin). The nurse should reinforce which instruction?

• A. Avoid foods high in vitamin K.
• B. Increase intake of dairy products.
• C. Limit intake of high-fiber foods.
• D. Avoid protein-rich foods.

Correct answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Clients taking warfarin need to be cautious with their vitamin K intake because vitamin K can counteract the effects of the medication. Therefore, it is essential to avoid foods high in vitamin K to maintain the therapeutic effects of warfarin. Choice B is incorrect because increasing dairy product intake is not specifically related to warfarin therapy. Choice C is incorrect as high-fiber foods do not interfere with warfarin therapy. Choice D is incorrect as protein-rich foods are not contraindicated with warfarin therapy.
