LPN Pharmacology Assessment A
1. The nurse is caring for a client who has undergone a coronary artery bypass graft (CABG) surgery. Which action should the nurse take to prevent postoperative complications?
- A. Encourage the client to cough and deep breathe every 1 to 2 hours.
- B. Maintain the client in a supine position at all times.
- C. Keep the client on bed rest for the first 48 hours.
- D. Restrict the client's fluid intake to prevent overload.
Correct answer: A
Rationale: Encouraging the client to cough and deep breathe every 1 to 2 hours is crucial post-CABG surgery to prevent respiratory complications, such as atelectasis and pneumonia. These actions help to expand lung volume, clear secretions, and prevent the collapse of alveoli. Choices B, C, and D are incorrect because maintaining the client in a supine position at all times can lead to complications like decreased lung expansion, keeping the client on bed rest for the first 48 hours may increase the risk of thromboembolism, and restricting fluid intake postoperatively can lead to dehydration and electrolyte imbalances.
2. When teaching a client with a new prescription for spironolactone, which instruction should the nurse include?
- A. Increase your intake of potassium-rich foods.
- B. Avoid consuming grapefruit juice.
- C. Take the medication with food.
- D. Monitor for signs of hyperkalemia.
Correct answer: D
Rationale: The correct answer is to instruct the client to monitor for signs of hyperkalemia when taking spironolactone since it is a potassium-sparing diuretic. Hyperkalemia is a potential adverse effect due to the medication's mechanism of action. Advising the client to increase potassium-rich foods (Choice A) would be incorrect as it can further elevate potassium levels, which could lead to hyperkalemia. Avoiding grapefruit juice (Choice B) is not directly related to spironolactone use. Though taking the medication with food (Choice C) can help reduce gastrointestinal upset, it is not the most critical instruction when initiating spironolactone therapy.
3. 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.
4. A client has a new prescription for metoprolol. Which of the following instructions should the nurse include?
- A. Monitor your blood pressure daily.
- B. Take the medication with food.
- C. Increase your intake of potassium-rich foods.
- D. Avoid consuming grapefruit juice.
Correct answer: A
Rationale: The correct answer is A, 'Monitor your blood pressure daily.' When a client is prescribed metoprolol, it is important to monitor blood pressure daily because the medication can cause hypotension, leading to low blood pressure. Regular monitoring allows for the early detection of any potential issues and adjustment of treatment if necessary. Choices B, C, and D are incorrect. Taking metoprolol with food is not necessary, increasing potassium-rich foods is not directly related to metoprolol therapy, and avoiding grapefruit juice is more relevant for certain other medications that interact with grapefruit.
5. The nurse is caring for a client with a diagnosis of myocardial infarction (MI) and is assisting the client in completing the diet menu. Which beverage does the nurse instruct the client to select from the menu?
- A. Tea
- B. Cola
- C. Coffee
- D. Lemonade
Correct answer: D
Rationale: Lemonade is the correct choice as it is caffeine-free, unlike tea, cola, and coffee, which contain caffeine that can potentially affect the client's heart rhythm. Caffeine can increase heart rate and blood pressure, which may not be advisable for a client with a recent MI. Tea, cola, and coffee should be avoided due to their caffeine content, which can have stimulant effects on the heart and may not be beneficial for a client recovering from a myocardial infarction.
