Nursing Elites

1. A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which finding indicates that the treatment is effective?

• A. Potassium level of 4.0 mEq/L.
• B. Blood glucose level of 180 mg/dL.
• C. Urine output of 50 mL/hour.
• D. Absence of ketones in the urine.

Correct answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.

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. A client with deep vein thrombosis (DVT) is prescribed heparin therapy. What laboratory value should the nurse monitor?

• A. Monitor the client’s liver function tests.
• B. Monitor the client’s prothrombin time (PT).
• C. Monitor the client’s partial thromboplastin time (PTT).
• D. Monitor the client’s red blood cell count.

Correct answer: C

Rationale: The correct answer is C: Monitor the client’s partial thromboplastin time (PTT). During heparin therapy for DVT, it is essential to monitor the PTT to assess the effectiveness of the medication in preventing clot formation. Monitoring the PTT helps ensure that the client is within the therapeutic range for anticoagulation. Choices A, B, and D are incorrect because liver function tests, prothrombin time (PT), and red blood cell count are not specifically monitored to assess the effectiveness of heparin therapy in preventing clot formation.

4. While auscultating heart sounds, the nurse hears a swishing sound. How should this sound be documented?

• A. Heart murmur.
• B. Murmur.
• C. S3 sound.
• D. S4 sound.

Correct answer: B

Rationale: The correct answer is B: 'Murmur.' A murmur is a swishing sound heard during auscultation, typically caused by turbulent blood flow through the heart or valves. Choices C and D, 'S3 sound' and 'S4 sound,' refer to specific heart sounds associated with different cardiac conditions, not the general description of a swishing sound. Choice A, 'Heart murmur,' is redundant as 'murmur' alone is sufficient to describe the swishing sound heard.

5. A 30-year-old male client reports difficulty sleeping due to anxiety about his upcoming surgery. What intervention would be most appropriate for the nurse to suggest?

• A. Suggest taking a mild sedative before bed.
• B. Encourage physical activity before bedtime.
• C. Advise listening to calming music before bed.
• D. Recommend reading a book before bed.

Correct answer: A

Rationale: The most appropriate intervention for the nurse to suggest to a 30-year-old male client experiencing difficulty sleeping due to anxiety about his upcoming surgery is to recommend taking a mild sedative before bed. A mild sedative can help manage anxiety and improve sleep in such situations. Encouraging physical activity before bedtime, advising to listen to calming music, or recommending reading a book may not directly address the client's anxiety and may not be as effective in promoting sleep in this scenario.
