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 client has a new prescription for heparin. Which of the following laboratory results should be monitored to evaluate the effectiveness of the medication?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the laboratory result that should be monitored to evaluate the effectiveness of heparin. Heparin works by prolonging the aPTT, and monitoring this parameter helps ensure the medication's effectiveness and safety in preventing clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor the effectiveness of warfarin, another anticoagulant. Platelet count is essential to assess platelet function and clotting disorders, but it is not specifically used to monitor heparin therapy.

3. When teaching a client about the use of lisinopril, which of the following instructions should the nurse include?

• A. Monitor your blood pressure regularly.
• B. Take the medication with food.
• C. Increase your intake of potassium-rich foods.
• D. Avoid grapefruit juice.

Correct answer: A

Rationale: The correct answer is to instruct the client to monitor their blood pressure regularly when taking lisinopril. Lisinopril is known to cause hypotension, so monitoring blood pressure is crucial to ensure it stays within a safe range. This monitoring helps in early detection of any potential issues related to low blood pressure, allowing for timely intervention. Choices B, C, and D are incorrect because taking lisinopril with food, increasing potassium-rich foods intake, and avoiding grapefruit juice are not specific instructions related to the safe and effective use of lisinopril.

4. The client with myocardial infarction should reduce intake of saturated fat and cholesterol. Which food items from the dietary menu would assist the nurse in helping the client comply with diet therapy?

• A. Cheeseburger, pan-fried potatoes, whole kernel corn, sherbet
• B. Pork chop, baked potato, cauliflower in cheese sauce, ice cream
• C. Baked haddock, steamed broccoli, herbed rice, sliced strawberries
• D. Spaghetti and sweet sausage in tomato sauce, vanilla pudding (with 4% milk)

Correct answer: C

Rationale: Option C, which includes baked haddock, steamed broccoli, herbed rice, and sliced strawberries, is the most appropriate choice for a client with myocardial infarction looking to reduce saturated fat and cholesterol intake. This meal is low in saturated fats and cholesterol, making it a heart-healthy option that aligns with the dietary recommendations for such clients. Choices A, B, and D contain foods high in saturated fats and cholesterol, which are not suitable for a client with myocardial infarction trying to adhere to a diet therapy aimed at reducing these components.

5. The nurse is informed during shift report that a client is experiencing occasional ventricular dysrhythmias. The nurse reviews the client's laboratory results, recalling that which electrolyte imbalance could be responsible for this development?

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

Correct answer: A

Rationale: Hypokalemia, which is low potassium levels, can disrupt the normal electrical activity of the heart and lead to ventricular dysrhythmias. Potassium plays a crucial role in maintaining the heart's rhythm, and a deficiency can result in dangerous heart rhythm abnormalities. Hypernatremia (Choice B), which is high sodium levels, does not directly impact heart rhythm. Hypochloremia (Choice C), which is low chloride levels, is not typically associated with ventricular dysrhythmias. Hypercalcemia (Choice D), which is high calcium levels, is not a common cause of ventricular dysrhythmias.
