LPN Pharmacology Practice Test
1. A client has a new prescription for enalapril. Which of the following adverse effects should the client be instructed to monitor and report?
- A. Frequent urination
- B. Tremors
- C. Dry mouth
- D. Persistent cough
Correct answer: D
Rationale: The correct answer is D: Persistent cough. Enalapril, an ACE inhibitor, is known to commonly cause a persistent cough as an adverse effect due to its effect on bradykinin levels. Clients should be instructed to monitor for a persistent cough and report it promptly to their healthcare provider for further evaluation and possible medication adjustment. Choices A, B, and C are incorrect as they are not commonly associated with enalapril use and are not typical adverse effects of ACE inhibitors.
2. The client with a history of angina pectoris is being discharged after coronary artery bypass graft (CABG) surgery. Which statement by the client indicates a need for further teaching?
- A. I will avoid lifting heavy objects for at least 6 weeks.
- B. I will call the doctor if I develop a fever or drainage from my incisions.
- C. I will take my pain medication before doing any activities that might cause discomfort.
- D. I can resume my normal activities, including driving, as soon as I feel like it.
Correct answer: D
Rationale: The correct answer is D because after CABG surgery, patients need to follow specific guidelines for resuming activities, and driving is typically restricted for a certain period to ensure safety and proper recovery. Resuming normal activities too soon, including driving, can pose risks to the client's health and safety. It is essential to emphasize to the client the importance of following the healthcare provider's recommendations regarding activity restrictions post-surgery to prevent complications and promote optimal recovery. Choices A, B, and C are correct statements that align with post-CABG discharge instructions, emphasizing the importance of avoiding heavy lifting, monitoring for signs of infection, and managing pain effectively.
3. 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.
4. When teaching a client who 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 metallic taste in your mouth.
Correct answer: C
Rationale: The correct instruction for a client starting metformin is to increase fluid intake. This is crucial to prevent gastrointestinal discomfort, a common side effect of metformin. Adequate hydration helps reduce the risk of gastrointestinal upset and ensures the medication is well-tolerated. Option A is generally true for metformin but is not as essential as maintaining proper hydration. Option B is important but not directly related to starting metformin. Option D is incorrect as a metallic taste in the mouth is not typically associated with metformin.
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.
