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. The LPN/LVN is reinforcing discharge instructions to a client who has been prescribed nitroglycerin sublingual tablets for angina. Which statement by the client indicates a need for further teaching?
- A. I will keep my nitroglycerin tablets in the original glass bottle.
- B. I will sit or lie down when I take a nitroglycerin tablet.
- C. I will take a nitroglycerin tablet every 5 minutes if chest pain persists, up to a total of 3 tablets.
- D. I can swallow the nitroglycerin tablet with a glass of water if it does not dissolve quickly.
Correct answer: D
Rationale: The correct answer is D. Nitroglycerin sublingual tablets should not be swallowed; they must dissolve under the tongue to be effective. Choice A is correct as nitroglycerin tablets should be stored in their original glass container to prevent degradation. Choice B is correct as sitting or lying down when taking a nitroglycerin tablet helps prevent dizziness or fainting due to a sudden drop in blood pressure. Choice C is correct as taking a nitroglycerin tablet every 5 minutes for a maximum of 3 tablets is the correct protocol for managing angina symptoms.
3. 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.
4. A client with a history of angina pectoris reports chest pain while ambulating in the corridor. What should the nurse do first?
- A. Check the client's vital signs.
- B. Assist the client to sit or lie down.
- C. Administer sublingual nitroglycerin.
- D. Apply nasal oxygen at a rate of 2 L/min.
Correct answer: B
Rationale: When a client with a history of angina pectoris experiences chest pain while ambulating, the priority action for the nurse is to assist the client to sit or lie down. This helps reduce the demand on the heart by decreasing physical exertion. Checking vital signs, administering medication, or applying oxygen can follow once the client is in a more comfortable position. Checking vital signs (Choice A) may be important but addressing the immediate discomfort by positioning the client comfortably takes precedence. Administering sublingual nitroglycerin (Choice C) is appropriate but should come after ensuring the client's comfort. Applying nasal oxygen (Choice D) can be beneficial, but it should not be the first action; assisting the client to sit or lie down is the initial priority.
5. Which laboratory test should be monitored to evaluate the effectiveness of anticoagulant therapy in a client with deep vein thrombosis (DVT)?
- A. Complete blood count (CBC)
- B. Activated partial thromboplastin time (aPTT)
- C. Serum electrolytes
- D. Liver function tests
Correct answer: B
Rationale: Activated partial thromboplastin time (aPTT) is the laboratory test monitored to evaluate the effectiveness of anticoagulant therapy, particularly with heparin. It measures the time it takes for blood to clot, and monitoring aPTT helps ensure the therapeutic range is maintained to prevent clot formation and excessive bleeding. Choices A, C, and D are incorrect because a complete blood count (CBC) assesses overall health, serum electrolytes evaluate the body's electrolyte balance, and liver function tests assess liver health, none of which directly evaluate the effectiveness of anticoagulant therapy for DVT.
