Nursing Elites

1. A client with chronic liver disease is prescribed lactulose. Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?

• A. Bilirubin level
• B. Serum ammonia level
• C. Serum potassium level
• D. Albumin level

Correct answer: B

Rationale: The correct answer is B: Serum ammonia level. Lactulose is used to lower serum ammonia levels in clients with chronic liver disease, particularly in cases of hepatic encephalopathy. Monitoring serum ammonia levels is crucial to evaluate the effectiveness of lactulose in managing hepatic encephalopathy. Choices A, C, and D are incorrect because they are not directly related to the action or evaluation of lactulose in chronic liver disease.

2. A client with cirrhosis is at risk for bleeding due to impaired liver function. Which laboratory result is the most important to monitor?

• A. Blood urea nitrogen (BUN)
• B. Prothrombin time (PT)
• C. Aspartate aminotransferase (AST)
• D. Serum albumin

Correct answer: B

Rationale: Prothrombin time (PT) measures the time it takes for blood to clot and is a critical indicator of bleeding risk in clients with liver dysfunction. Impaired liver function reduces clotting factor production, leading to an increased PT, which requires close monitoring. Monitoring BUN (Choice A) is more indicative of kidney function, not clotting ability. Aspartate aminotransferase (AST) (Choice C) and serum albumin (Choice D) are important indicators of liver function, but they do not directly assess the client's bleeding risk.

3. 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.

4. During an assessment of a client with congestive heart failure, the nurse is most likely to hear which of the following upon auscultation of the heart?

• A. S3 ventricular gallop
• B. Apical click
• C. Systolic murmur
• D. Split S2

Correct answer: A

Rationale: Correct Answer: An S3 ventricular gallop is an abnormal heart sound commonly heard in clients with congestive heart failure. This sound is indicative of fluid overload or volume expansion in the ventricles, which is often present in heart failure. <br> Incorrect Answers: <br> B: An apical click is not typically associated with congestive heart failure. <br> C: A systolic murmur may be heard in various cardiac conditions but is not specific to congestive heart failure. <br> D: A split S2 refers to a normal heart sound caused by the closure of the aortic and pulmonic valves at slightly different times during inspiration, not directly related to congestive heart failure.

5. A client with bipolar disorder is prescribed lithium. What should the nurse teach the client about lithium toxicity?

• A. Take the medication with meals to prevent gastrointestinal upset.
• B. Report any symptoms of nausea, vomiting, or diarrhea.
• C. Monitor lithium levels regularly and maintain hydration.
• D. Avoid taking nonsteroidal anti-inflammatory drugs (NSAIDs) while on lithium.

Correct answer: D

Rationale: The correct answer is D. Clients taking lithium should avoid NSAIDs as they can increase lithium levels leading to toxicity. It is essential to monitor lithium levels regularly and maintain hydration to prevent toxicity. Reporting symptoms like nausea, vomiting, or diarrhea is important, but the key teaching point regarding lithium toxicity is to avoid NSAIDs.
