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 with acute pancreatitis is admitted with severe, piercing abdominal pain and an elevated serum amylase. Which additional information is the client most likely to report to the nurse?

• A. Pain radiates to the back
• B. Nausea and vomiting without relief
• C. Abdominal pain decreases when lying supine
• D. Abdominal pain is worse after eating

Correct answer: D

Rationale: The correct answer is D. In acute pancreatitis, abdominal pain typically worsens after eating due to the stimulation of the pancreas to release enzymes that irritate the inflamed tissues. Pain relief when lying supine is uncommon and usually exacerbates discomfort. While nausea and vomiting are common symptoms, they are not as indicative of changes in pain intensity. Pain radiating to the back is characteristic but does not specifically relate to exacerbation post-eating.

3. An older adult client with gastroenteritis has been taking the antidiarrheal diphenoxylate for the past 24 hours. What finding requires the nurse to take further action?

• A. Monitor the client’s fluid intake.
• B. Obtain a stool sample for testing.
• C. Administer a laxative to clear the infection.
• D. Assess skin turgor and provide fluids.

Correct answer: D

Rationale: The correct answer is D. Assessing skin turgor is crucial as tented skin turgor indicates dehydration, which can be worsened by antidiarrheal medications like diphenoxylate. Providing fluids is essential to address dehydration in this client. Monitoring fluid intake (choice A) is important, but assessing skin turgor takes precedence in this situation. Obtaining a stool sample for testing (choice B) could be necessary for diagnostic purposes but is not the immediate priority. Administering a laxative (choice C) is contraindicated in this case as it can worsen the client's condition by further exacerbating fluid loss.

4. A client is admitted with diabetic ketoacidosis (DKA). Which laboratory result would the nurse expect to find in this client?

• A. pH level of 7.45
• B. Serum calcium of 15 mg/dL
• C. Blood glucose of 450 mg/dL
• D. Sodium level of 120 mEq/L

Correct answer: C

Rationale: Clients with diabetic ketoacidosis typically present with elevated blood glucose levels, often above 300 mg/dL. This high blood glucose level, along with other symptoms, helps confirm the diagnosis of DKA. A pH level of 7.45 would be indicative of alkalosis, not the acidosis seen in DKA. A serum calcium level of 15 mg/dL is significantly elevated and is not a typical finding in DKA. A sodium level of 120 mEq/L indicates hyponatremia, which is not a characteristic laboratory finding in DKA.

5. A client recently started on warfarin therapy. What laboratory value is most important to monitor for this client?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Creatinine level
• D. Blood urea nitrogen (BUN)

Correct answer: B

Rationale: Prothrombin time (PT) is the most important laboratory value to monitor for clients on warfarin therapy. PT helps determine how long it takes blood to clot and ensures the warfarin dose is within the therapeutic range to prevent either excessive bleeding or clotting. Monitoring platelet count is important for assessing the risk of bleeding, but PT is more specific to warfarin therapy. Creatinine level and BUN are indicators of kidney function and are not directly related to warfarin therapy.
