LPN Pharmacology Questions
1. A healthcare professional is assessing a client who has been taking digoxin. Which of the following findings should the healthcare professional report to the provider?
- A. Weight gain
- B. Dry cough
- C. Hypokalemia
- D. Bradycardia
Correct answer: D
Rationale: The correct answer is D: Bradycardia. Bradycardia is a significant finding associated with digoxin toxicity. Digoxin, a medication commonly used to treat heart conditions, can lead to bradycardia as a sign of toxicity. Bradycardia requires immediate attention and reporting to the healthcare provider for further evaluation and management to prevent serious complications. Choices A, B, and C are incorrect because weight gain, dry cough, and hypokalemia are not specific signs of digoxin toxicity. While weight gain can be a side effect of digoxin, it is not a classic sign of toxicity. Dry cough is more commonly associated with medications like ACE inhibitors, and hypokalemia can be a complication of digoxin therapy but is not a direct sign of toxicity.
2. A client has a new prescription for amitriptyline. Which of the following instructions should the nurse include?
- A. Take the medication in the morning.
- B. Avoid consuming grapefruit juice.
- C. Take the medication with a full glass of water.
- D. Monitor for signs of weight gain.
Correct answer: C
Rationale: When a client is prescribed amitriptyline, it is important to instruct them to take the medication with a full glass of water. This instruction helps prevent esophageal irritation, as amitriptyline can be harsh on the esophagus. Option C is the correct choice. Option A, taking the medication in the morning, is not specific to amitriptyline and can vary depending on the individual's condition. Option B, avoiding grapefruit juice, is a general precaution for many medications but not specifically related to amitriptyline. Option D, monitoring for signs of weight gain, is not a direct instruction for taking the medication itself and may not be a common side effect of amitriptyline.
3. The client with a history of coronary artery disease (CAD) is scheduled for a stress test. What instruction should the nurse provide to the client before the test?
- A. Continue taking your usual dose of beta-blockers
- B. Refrain from eating or drinking anything for 4 hours before the test
- C. Wear loose, comfortable clothing and walking shoes
- D. Avoid any physical activity for 24 hours before the test
Correct answer: C
Rationale: Before a stress test, the nurse should instruct the client to wear loose, comfortable clothing and walking shoes. This is essential as the stress test involves physical exercise, and the client should be ready for the activity involved. Continuing beta-blockers should be based on healthcare provider's instructions; adjustments may be needed. Fasting before the test is usually not necessary. Avoiding physical activity for 24 hours before the test is not recommended as it may affect the accuracy of the test results by not providing a true reflection of the client's exercise capacity.
4. The LPN/LVN is assisting in caring for a client in the telemetry unit and is monitoring the client for cardiac changes indicative of hypokalemia. Which occurrence noted on the cardiac monitor indicates the presence of hypokalemia?
- A. Tall, peaked T waves
- B. ST-segment depression
- C. Prolonged P-R interval
- D. Widening of the QRS complex
Correct answer: B
Rationale: ST-segment depression can indicate hypokalemia, affecting the heart's electrical conduction. Hypokalemia leads to alterations in the repolarization phase of the cardiac action potential, resulting in ST-segment depression on the ECG. Tall, peaked T waves are indicative of hyperkalemia, not hypokalemia. A prolonged P-R interval is more commonly associated with first-degree heart block. Widening of the QRS complex is typically seen in conditions like bundle branch blocks or ventricular tachycardia, not specifically in hypokalemia.
5. The healthcare provider is reviewing the medication orders for a client with angina pectoris. Which medication is typically prescribed to prevent angina attacks?
- A. Aspirin
- B. Nitroglycerin
- C. Atenolol
- D. Simvastatin
Correct answer: B
Rationale: Nitroglycerin is the medication typically prescribed to prevent angina attacks. It works by dilating blood vessels, increasing blood flow, and reducing the heart's workload, hence relieving angina symptoms. Aspirin is often used to prevent blood clots, not specifically to prevent angina attacks. Atenolol is a beta-blocker used to manage high blood pressure and chest pain but is not typically prescribed to prevent angina attacks. Simvastatin is a statin medication primarily used to lower cholesterol levels and is not indicated for preventing angina attacks.
