LPN Pharmacology Practice Questions
1. What should be the nurse's priority action when a client diagnosed with angina pectoris complains of chest pain while taking a brisk walk?
- A. Administer nitroglycerin
- B. Have the client sit down
- C. Obtain an electrocardiogram
- D. Apply oxygen
Correct answer: B
Rationale: The nurse's priority action when a client diagnosed with angina pectoris complains of chest pain while taking a brisk walk is to have the client sit down. Sitting down reduces the workload on the heart and may alleviate pain by improving oxygen supply. This action aims to reduce the strain on the heart and improve oxygen delivery to the myocardium, which can help relieve the symptoms of angina pectoris. Administering nitroglycerin could be the next step after having the client sit down if the pain persists. Obtaining an electrocardiogram and applying oxygen are not the immediate priority actions when dealing with angina pectoris symptoms.
2. The LPN/LVN is assisting with the care of a client who has been diagnosed with a myocardial infarction (MI). Which laboratory test result would the nurse expect to see elevated within the first 24 hours of the client's admission?
- A. Serum troponin
- B. Serum creatinine
- C. Serum sodium
- D. Serum albumin
Correct answer: A
Rationale: Elevated serum troponin levels are indicative of myocardial damage and are commonly used as a diagnostic marker for myocardial infarction. Troponin levels typically rise within a few hours of an MI and remain elevated for several days, making it a crucial test for early detection and monitoring of cardiac injury. Serum creatinine is not typically elevated in the acute phase of a myocardial infarction. Serum sodium and serum albumin levels are not directly associated with myocardial infarction and are unlikely to be elevated in the first 24 hours following an MI.
3. A client admitted with coronary artery disease (CAD) reports dyspnea at rest. What intervention should the nurse prioritize?
- A. Providing a walker to aid in ambulation
- B. Elevating the head of the bed to at least 45 degrees
- C. Performing continuous monitoring of oxygen saturation
- D. Placing an oxygen cannula at the bedside for use if needed
Correct answer: B
Rationale: In a client with coronary artery disease (CAD) experiencing dyspnea at rest, the priority intervention should be to elevate the head of the bed to at least 45 degrees. This position helps reduce the work of breathing, optimizes lung expansion, and can alleviate symptoms of dyspnea by improving oxygenation and ventilation. Providing a walker for ambulation, monitoring oxygen saturation, and having an oxygen cannula at the bedside are important interventions but not the priority when the client is experiencing dyspnea at rest. Elevating the head of the bed is crucial to improve respiratory function and should be prioritized in this situation.
4. The client is receiving anticoagulant therapy for atrial fibrillation. Which laboratory test should be monitored to determine the effectiveness of the therapy?
- A. Prothrombin time (PT) and international normalized ratio (INR)
- B. Activated partial thromboplastin time (aPTT)
- C. Platelet count
- D. Erythrocyte sedimentation rate (ESR)
Correct answer: A
Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of anticoagulant therapy in clients with atrial fibrillation. These tests help ensure that the client is within the therapeutic range and are commonly used to assess the clotting ability of the blood. Monitoring PT and INR levels allows healthcare providers to adjust anticoagulant dosages as needed to prevent complications such as bleeding or thrombosis. Activated partial thromboplastin time (aPTT) is more commonly used to monitor heparin therapy, not anticoagulant therapy for atrial fibrillation. Platelet count assesses the number of platelets in the blood and is not a direct indicator of anticoagulant therapy effectiveness. Erythrocyte sedimentation rate (ESR) is a nonspecific marker of inflammation and is not used to monitor anticoagulant therapy.
5. The healthcare professional is assisting in the care of a client diagnosed with heart failure. The client is receiving furosemide (Lasix). Which laboratory value should the healthcare professional monitor most closely?
- A. Serum calcium
- B. Serum potassium
- C. Serum sodium
- D. Serum glucose
Correct answer: B
Rationale: Furosemide is a loop diuretic that can lead to significant potassium loss, making it crucial to monitor the client's serum potassium levels. Hypokalemia (low potassium levels) can result from furosemide use, potentially leading to adverse effects such as cardiac dysrhythmias. Therefore, close monitoring of serum potassium levels is essential to prevent complications in clients receiving furosemide. Monitoring serum calcium, sodium, or glucose levels is not the priority when administering furosemide.
