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 recently started on warfarin therapy. What laboratory value is most important to monitor for this client?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Creatinine level
• D. Blood urea nitrogen (BUN)

Correct answer: B

Rationale: Prothrombin time (PT) is the most important laboratory value to monitor for clients on warfarin therapy. PT helps determine how long it takes blood to clot and ensures the warfarin dose is within the therapeutic range to prevent either excessive bleeding or clotting. Monitoring platelet count is important for assessing the risk of bleeding, but PT is more specific to warfarin therapy. Creatinine level and BUN are indicators of kidney function and are not directly related to warfarin therapy.

3. A client with chronic obstructive pulmonary disease (COPD) is being discharged home. What should the nurse include in the discharge teaching?

• A. Limit fluid intake to prevent lung congestion
• B. Avoid all physical activity to conserve energy
• C. Perform pursed-lip breathing during activities
• D. Increase oxygen flow rate if shortness of breath occurs

Correct answer: C

Rationale: The correct answer is C. Pursed-lip breathing helps control breathing and improves oxygen exchange in clients with COPD. It can ease shortness of breath during activities and should be included in discharge teaching to manage symptoms. Option A is incorrect as adequate fluid intake is important for thinning mucus in COPD. Option B is wrong as physical activity, as tolerated, is beneficial for COPD patients. Option D is also incorrect because changing oxygen flow rate without healthcare provider guidance can be dangerous.

4. The nurse is administering a new medication to a client. What is the priority action before administering the drug?

• A. Verify the client's allergies
• B. Check the client's blood pressure
• C. Assess the client's pain level
• D. Provide client education on the medication

Correct answer: A

Rationale: Verifying the client's allergies is the priority action before administering any medication. It is crucial to identify any known allergies to prevent potential allergic reactions, which can be severe and life-threatening. Checking the client's blood pressure, assessing pain levels, and providing education on the medication are important aspects of client care but verifying allergies is essential for ensuring the safety of the client.

5. The nurse is caring for a client with fluid overload. The most reliable indicator of fluid volume status is

• A. Body weight
• B. Intake and output
• C. Daily weight
• D. Skin turgor

Correct answer: C

Rationale: Daily weight is the most reliable indicator of fluid volume status as it reflects changes in body fluid balance accurately. Body weight alone can fluctuate due to various factors, including food intake and bowel movements, which may not accurately represent fluid status. Intake and output provide information on fluid balance over time but may not reflect immediate changes. Skin turgor is a physical assessment finding that indicates hydration status, not overall fluid volume status.
