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. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?

• A. Decreased liver enzymes.
• B. Increased hydrostatic pressure in portal circulation.
• C. High bilirubin levels.
• D. Fluid shifts due to decreased serum proteins.

Correct answer: B

Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.

3. The client with a below-the-knee amputation is being taught about proper care of the residual limb. The most important point to emphasize would be

• A. Wrap the stump with an elastic bandage to prevent swelling
• B. Keep the skin on the stump clean and dry
• C. Use alcohol to cleanse the stump daily
• D. Apply moisturizing lotion to the stump daily

Correct answer: B

Rationale: The correct answer is B: Keep the skin on the stump clean and dry. This is crucial for preventing infection and promoting healing of the residual limb. Wrapping the stump with an elastic bandage can constrict blood flow and cause issues. Using alcohol to cleanse the stump daily can be too harsh and drying for the skin, leading to irritation. Applying moisturizing lotion daily is not as essential as keeping the skin clean and dry to prevent complications.

4. A client with cirrhosis is admitted with ascites and peripheral edema. Which intervention should the nurse implement first?

• A. Elevate the legs to reduce swelling.
• B. Restrict fluids to reduce fluid overload.
• C. Administer furosemide to reduce fluid overload.
• D. Monitor the client's intake and output.

Correct answer: C

Rationale: Administering a diuretic like furosemide is the priority intervention for a client with cirrhosis, ascites, and peripheral edema. Furosemide helps reduce fluid overload by promoting diuresis. Elevating the legs may provide some symptomatic relief but does not address the underlying issue of fluid overload. Restricting fluids is not appropriate initially as the client needs proper hydration while managing fluid balance. Monitoring intake and output is important but not the first action to address the immediate fluid overload in this client.

5. Which dietary instruction is most important for a client with renal disease?

• A. Avoid all protein-rich foods.
• B. Limit fluid intake to 1500 ml/day.
• C. Increase potassium intake to prevent weakness.
• D. Eat small, frequent meals high in carbohydrates.

Correct answer: B

Rationale: The most important dietary instruction for a client with renal disease is to limit fluid intake to 1500 ml/day. This is essential to prevent fluid overload, manage electrolyte balance, and reduce strain on the kidneys. Choice A is incorrect because while protein restriction may be necessary in some cases, avoiding all protein-rich foods is not recommended as some protein intake is essential for overall health. Choice C is incorrect because increasing potassium intake is generally not advised for clients with renal disease, as they often need to limit potassium intake. Choice D is also incorrect because while consuming small, frequent meals may be helpful, emphasizing a diet high in carbohydrates is not typically the primary focus for clients with renal disease.
