1. Which laboratory test should be monitored to evaluate the effectiveness of anticoagulant therapy in a client with deep vein thrombosis (DVT)?

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.

2. A client is receiving intravenous heparin therapy for the treatment of deep vein thrombosis (DVT). Which laboratory test result should the LPN/LVN monitor to ensure the client is receiving a therapeutic dose?

Correct answer: B

Rationale: The correct laboratory test result that the LPN/LVN should monitor to ensure the client is receiving a therapeutic dose of heparin therapy is the activated partial thromboplastin time (aPTT). The aPTT test is specifically used to monitor heparin therapy, ensuring that the dose administered is within the therapeutic range. Monitoring aPTT helps to prevent complications such as bleeding or clot formation by maintaining the appropriate anticoagulant effect of heparin. Prothrombin time (PT) and International normalized ratio (INR) are more commonly used to monitor warfarin therapy, not heparin. Platelet count is not a direct indicator of heparin's therapeutic effect and is not used to monitor heparin therapy.

3. The client with a diagnosis of heart failure is receiving furosemide (Lasix). Which laboratory value is most important for the nurse to monitor?

Correct answer: C

Rationale: The correct answer is C: Serum potassium. When a client is receiving furosemide, a loop diuretic, it can lead to potassium loss. Monitoring the serum potassium levels is crucial to prevent life-threatening complications such as cardiac arrhythmias. Blood glucose (Choice A) is not directly impacted by furosemide. Serum sodium (Choice B) may be affected, but monitoring potassium is more critical due to the risk of arrhythmias. Blood urea nitrogen (BUN) (Choice D) is important for assessing kidney function but is not the most crucial value to monitor in a client taking furosemide.

4. A nurse is assessing a client who has a new prescription for enalapril. Which of the following findings is a priority for the nurse to report to the provider?

Correct answer: D

Rationale: The correct answer is D: Dizziness. Dizziness is a sign of hypotension, a potential adverse effect of enalapril. Enalapril is an ACE inhibitor commonly prescribed for hypertension. Hypotension is a serious side effect that can lead to complications such as falls and injuries. Reporting dizziness promptly is crucial to prevent any harm to the client. Choices A, B, and C are not directly associated with enalapril use and are less concerning compared to the potential implications of hypotension indicated by dizziness.

5. The healthcare provider is teaching a client about the use of nitroglycerin patches for angina pectoris. Which instruction should the healthcare provider include?

Correct answer: D

Rationale: Rotating the application site every 24 hours is crucial when using nitroglycerin patches to prevent skin irritation and ensure consistent absorption of the medication. By rotating the site, the risk of local skin reactions is reduced, and the effectiveness of the nitroglycerin patch is maintained. Applying the patch to the same site each day (Choice A) can lead to skin irritation. Removing the patch at bedtime (Choice B) is not necessary as long as the prescribed wearing schedule is followed. Covering the patch with a bandage (Choice C) is not recommended as it may interfere with proper absorption.
