Nursing Elites

1. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.

2. The nurse is caring for a client with a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Which intervention is most important for the nurse to implement?

• A. Encourage oral hydration
• B. Monitor for signs of dehydration
• C. Restrict fluid intake
• D. Administer IV fluids as prescribed

Correct answer: C

Rationale: In SIADH, there is excessive ADH secretion leading to water retention and dilutional hyponatremia. The most crucial intervention is to restrict fluid intake to prevent further fluid overload and worsening of hyponatremia. Encouraging oral hydration (choice A) would exacerbate the condition by adding more fluids. Monitoring for signs of dehydration (choice B) is not appropriate as the client is at risk of fluid overload. Administering IV fluids (choice D) would worsen the hyponatremia and should be avoided.

3. A client with diabetes mellitus is experiencing diabetic ketoacidosis (DKA). What laboratory result should the nurse monitor closely?

• A. White blood cell count of 15,000.
• B. Blood glucose level of 320 mg/dL.
• C. Sodium level of 145 mEq/L.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: B

Rationale: A blood glucose level of 320 mg/dL indicates the need for insulin to manage diabetic ketoacidosis.

4. The nurse prepares to teach clients about blood glucose monitoring. When should clients always check glucose, regardless of age or type of diabetes?

• A. Before going to bed.
• B. After meals.
• C. During acute illness.
• D. Prior to exercising.

Correct answer: C

Rationale: The correct answer is C: During acute illness. Checking blood glucose during acute illness is crucial as stress can elevate glucose levels. This monitoring is essential regardless of the client's age or the type of diabetes they have. Checking before going to bed (choice A) may be important for some individuals, but it's not as universally necessary as during acute illness. Checking after meals (choice B) and prior to exercising (choice D) are important times for monitoring blood glucose, but they are not as universally applicable as during acute illness.

5. While caring for a client's postoperative dressing, the nurse observes purulent drainage at the wound. Before reporting this finding to the healthcare provider, the nurse should review which of the client's laboratory values?

• A. White blood cell count
• B. Hemoglobin
• C. Serum creatinine
• D. Culture for sensitive organisms

Correct answer: D

Rationale: Purulent drainage suggests an infection at the wound site. Reviewing the culture and sensitivity results will guide appropriate antibiotic treatment by identifying the causative organisms and their antibiotic sensitivities. Elevated white blood cells indicate infection but do not specify the organism. Creatinine and hemoglobin values are unrelated to wound infections.
