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 male client admitted for schizophrenia is noted to be diaphoretic and pacing the hallway. What is the most important intervention?

• A. Take the client's temperature and blood pressure.
• B. Encourage the client to rest.
• C. Plan an activity involving physical exercise.
• D. Carefully observe the client throughout the shift.

Correct answer: D

Rationale: In this scenario, the most important intervention for a male client with schizophrenia who is diaphoretic and pacing the hallway is to carefully observe the client throughout the shift. Diaphoresis and pacing can be indicators of agitation or distress in clients with schizophrenia. Careful observation is crucial to monitor the client's safety, assess for any potential escalation of symptoms, and provide timely intervention if needed. Taking the client's temperature and blood pressure (Choice A) may not address the immediate need for safety and observation. Encouraging the client to rest (Choice B) may not be effective if the client is agitated. Planning an activity involving physical exercise (Choice C) could potentially exacerbate the situation rather than addressing the immediate need for observation and safety.

3. A client presents with a suspected infection and has a fever of 102°F. What is the nurse's immediate priority?

• A. Administer antipyretics as ordered
• B. Take a blood culture before administering antibiotics
• C. Encourage fluid intake to prevent dehydration
• D. Monitor vital signs every hour

Correct answer: B

Rationale: The immediate priority for a client with a suspected infection and fever is to take a blood culture before administering antibiotics. This step is crucial to identify the causative organism and ensure appropriate treatment. Administering antipyretics or encouraging fluid intake are important but should come after obtaining the blood culture to avoid interfering with test results. Monitoring vital signs, although essential, is not the immediate priority compared to identifying the infectious agent.

4. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?

• A. Platelet count
• B. Prothrombin time (PT)
• C. White blood cell count
• D. Hemoglobin level

Correct answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.

5. A client reports dizziness when standing up quickly. What advice should the nurse give?

• A. Encourage the client to drink more fluids.
• B. Change positions slowly to prevent dizziness.
• C. Report the symptom to the healthcare provider immediately.
• D. Limit physical activity to avoid triggering dizziness.

Correct answer: B

Rationale: The correct advice for a client experiencing dizziness when standing up quickly is to change positions slowly to prevent dizziness. This symptom is suggestive of postural hypotension, where a sudden change in position can lead to a drop in blood pressure, causing dizziness. Encouraging the client to drink more fluids (Choice A) may be beneficial for other conditions but is not directly related to the prevention of dizziness in this case. Reporting the symptom to the healthcare provider immediately (Choice C) is important if the dizziness is persistent or severe, but the immediate action to prevent it is to change positions slowly. Limiting physical activity (Choice D) may not necessarily address the underlying cause of dizziness in this context.
