Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. A client with tuberculosis is prescribed rifampin. What side effect should the nurse inform the client about?

• A. Report orange-colored urine as a sign of kidney dysfunction.
• B. Expect red-orange discoloration of urine as a harmless side effect.
• C. Monitor for signs of liver toxicity.
• D. Call the healthcare provider if vision changes occur.

Correct answer: B

Rationale: The correct answer is B. Rifampin can cause red-orange discoloration of bodily fluids, including urine, saliva, and tears. This is a harmless side effect, but clients should be informed beforehand to prevent alarm. Choice A is incorrect as orange-colored urine is not a sign of kidney dysfunction related to rifampin. Choice C is incorrect because rifampin is more commonly associated with liver toxicity rather than kidney dysfunction. Choice D is incorrect as vision changes are not a typical side effect of rifampin.

3. A client with deep vein thrombosis (DVT) is prescribed heparin. What lab value should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT).
• B. Partial thromboplastin time (PTT).
• C. International Normalized Ratio (INR).
• D. Hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

4. An older adult client with heart failure (HF) and hypertension (HTN) is receiving atenolol, furosemide, and enalapril. Which assessments are essential to evaluate the effectiveness of the medications?

• A. Bowel sounds and daily weight.
• B. Daily weight and blood pressure.
• C. Heart sounds and range of motion.
• D. Monitor for evidence of hypokalemia.

Correct answer: B

Rationale: Monitoring daily weight and blood pressure is crucial to assess the effectiveness of diuretics (furosemide) and antihypertensives (atenolol, enalapril) in managing heart failure and hypertension. Changes in weight indicate fluid status, while blood pressure readings reflect the control of hypertension. Assessing bowel sounds and range of motion are important but not directly related to evaluating the effectiveness of these specific medications in this scenario. Monitoring for hypokalemia is important due to furosemide's potential side effect, but it is not the primary assessment to evaluate medication effectiveness.

5. An older client with type 1 diabetes arrives at the clinic with abdominal cramping, vomiting, lethargy, and confusion. What should the nurse implement first?

• A. Start an IV infusion of normal saline.
• B. Obtain a serum potassium level.
• C. Administer the client's usual dose of insulin.
• D. Assess the pupillary response to light.

Correct answer: A

Rationale: The correct answer is A: Start an IV infusion of normal saline. The client is showing signs of dehydration, such as abdominal cramping, vomiting, lethargy, and confusion, which can be exacerbated by hyperglycemia. Rehydration is the initial priority to address the fluid imbalance. Option B, obtaining a serum potassium level, though important in the management of diabetes, is not the immediate priority over rehydration. Option C, administering the client's usual dose of insulin, should only be done after addressing the dehydration and confirming the client's blood glucose levels. Option D, assessing the pupillary response to light, is not the most urgent intervention needed in this situation compared to rehydration to correct fluid imbalance.
