LPN Pharmacology Practice Questions

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?

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. The healthcare provider is reinforcing dietary instructions to a client with coronary artery disease who has been prescribed a low-cholesterol diet. The healthcare provider should advise the client to choose which food item?

Correct answer: B

Rationale: Oatmeal with fresh fruit is the correct choice for a client with coronary artery disease on a low-cholesterol diet. Oatmeal is a heart-healthy option that is low in cholesterol and saturated fats. Fresh fruits are also a good source of essential nutrients and fiber. Choices A, C, and D are not suitable for a low-cholesterol diet. Whole milk, fried chicken, bacon, and eggs are high in cholesterol and saturated fats, which can be detrimental to individuals with coronary artery disease.

3. 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?

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.

4. The LPN/LVN is assisting in caring for a client in the telemetry unit who is receiving an intravenous infusion of 1000 mL of 5% dextrose with 40 mEq of potassium chloride. Which occurrence observed on the cardiac monitor indicates the presence of hyperkalemia?

Correct answer: A

Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications. ST segment depressions, shortened P-R intervals, and shortening of the QRS complex are not typically associated with hyperkalemia. ST segment depressions are more indicative of myocardial ischemia or infarction. Shortened P-R intervals may be seen in conditions like Wolff-Parkinson-White syndrome. Shortening of the QRS complex is associated with conditions affecting the conduction system of the heart, such as bundle branch blocks.

5. A client diagnosed with hypertension is prescribed atenolol (Tenormin). The nurse should monitor the client for which common side effect of this medication?

Correct answer: C

Rationale: Atenolol is a beta-blocker that works by lowering blood pressure. A common side effect of atenolol is hypotension, where blood pressure drops too low. Therefore, the nurse should monitor the client for signs and symptoms of hypotension to prevent any complications. Choices A, B, and D are incorrect because tachycardia (fast heart rate), dry mouth, and increased appetite are not common side effects of atenolol. Hypotension is the expected side effect due to the medication's mechanism of action.
