Nursing Elites

1. 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.

2. 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.

3. A client undergoing chemotherapy reports extreme fatigue. What should the nurse recommend to manage this symptom?

• A. Increase the dose of chemotherapy.
• B. Rest when needed and maintain a balanced diet.
• C. Perform light physical activity to reduce fatigue.
• D. Consider delaying the chemotherapy treatment.

Correct answer: B

Rationale: The correct recommendation for managing chemotherapy-induced fatigue is to advise the client to rest when needed and maintain a balanced diet. Increasing the dose of chemotherapy (Choice A) would exacerbate the fatigue and other side effects. While light physical activity (Choice C) can be beneficial, extreme fatigue may require more rest initially. Delaying chemotherapy treatment (Choice D) should only be considered after consultation with the healthcare provider, as timely treatment is usually crucial in cancer care.

4. An older adult client is admitted with pneumonia and prescribed penicillin G potassium. Which factor increases the risk of an adverse reaction?

• A. Sputum culture showing Streptococcus pneumoniae.
• B. Previous treatment with penicillin.
• C. Daily use of spironolactone for hypertension.
• D. Documented allergy to sulfa drugs.

Correct answer: C

Rationale: The correct answer is C. Daily use of spironolactone for hypertension can increase the risk of hyperkalemia and interact with penicillin, leading to adverse reactions. Choice A is incorrect because the sputum culture showing Streptococcus pneumoniae is an expected finding in a patient with pneumonia and does not increase the risk of an adverse reaction to penicillin. Choice B is incorrect as previous treatment with penicillin does not necessarily increase the risk of an adverse reaction to penicillin if there was no history of allergic reactions. Choice D is also incorrect as a documented allergy to sulfa drugs does not directly increase the risk of an adverse reaction to penicillin.

5. The nurse is assessing a client with a history of schizophrenia who reports feeling sedated after starting a new antipsychotic medication. Which intervention is most appropriate?

• A. Reassure the client that sedation will subside with continued use
• B. Instruct the client to take the medication at bedtime
• C. Teach the client to take the medication with food
• D. Consult the healthcare provider to reduce the dosage

Correct answer: B

Rationale: Instructing the client to take the medication at bedtime is the most appropriate intervention. Taking antipsychotic medications at bedtime can help reduce the impact of sedation on the client's daily activities. This approach allows the client to sleep through the sedative effects. Choice A is incorrect because just reassuring the client may not address the immediate issue of sedation. Choice C is incorrect as taking the medication with food does not directly address the sedation concern. Choice D is not the first-line intervention; adjusting the dosage should be done by the healthcare provider after assessing the client's response to the medication.
