LPN Pharmacology Practice Test
1. 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.
2. A client with coronary artery disease is prescribed a low-cholesterol diet. The nurse should reinforce which dietary selection made by the client?
- A. Eggs and bacon
- B. Oatmeal with fresh fruit
- C. Cream of chicken soup
- D. Grilled cheese sandwich
Correct answer: B
Rationale: Oatmeal with fresh fruit is a suitable choice for a client with coronary artery disease prescribed a low-cholesterol diet. This option is high in fiber and nutrients, making it a heart-healthy selection. Oatmeal and fresh fruits are low in cholesterol and saturated fats, which helps in managing coronary artery disease. Choices A, C, and D are higher in cholesterol and saturated fats, which can be detrimental for individuals with this condition.
3. The client is reinforcing instructions for a low-sodium diet. Which statement by the client indicates a need for further teaching?
- A. I will avoid adding salt to my food while cooking.
- B. I will use salt substitutes instead of regular salt.
- C. I can eat as much processed food as I like since it's usually low in sodium.
- D. I will read food labels to check for sodium content.
Correct answer: C
Rationale: The correct answer is C. Processed foods often contain high amounts of sodium, so they should be limited or avoided on a low-sodium diet. Choosing processed foods can lead to increased sodium intake, counteracting the purpose of following a low-sodium diet. Option A shows an understanding of avoiding added salt, Option B suggests using alternatives to regular salt, and Option D indicates a willingness to check food labels for sodium content, all of which are appropriate for a low-sodium diet. Therefore, the client's statement about eating processed foods freely is incorrect and requires further teaching.
4. The nurse is preparing to administer a scheduled dose of enalapril (Vasotec) to a client with hypertension. Before administering the medication, the nurse should check which priority assessment?
- A. Heart rate
- B. Blood pressure
- C. Respiratory rate
- D. Temperature
Correct answer: B
Rationale: Before administering enalapril, an antihypertensive medication, the nurse should prioritize checking the client's blood pressure. Monitoring blood pressure helps ensure it is at an acceptable level before giving the medication, as enalapril can further lower blood pressure. This assessment is crucial in preventing potential hypotensive episodes and adverse effects associated with excessive blood pressure reduction. Heart rate, respiratory rate, and temperature are important assessments but are not the priority before administering enalapril, which primarily affects blood pressure levels.
5. A client with heart failure is prescribed furosemide (Lasix). The nurse should monitor the client for which potential electrolyte imbalance?
- A. Hyperkalemia
- B. Hypernatremia
- C. Hypokalemia
- D. Hypocalcemia
Correct answer: C
Rationale: When a client with heart failure is prescribed furosemide, the nurse should monitor for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, which increases the risk of hypokalemia. Hypokalemia can have serious implications such as cardiac dysrhythmias. Therefore, it is essential to closely monitor the client's serum potassium levels while on furosemide to prevent complications. Hyperkalemia (Choice A) is incorrect because furosemide leads to potassium loss, not retention. Hypernatremia (Choice B) is not typically associated with furosemide use. Hypocalcemia (Choice D) is not a common electrolyte imbalance caused by furosemide.
