1. In a client with liver cirrhosis experiencing confusion and disorientation, what condition is most likely causing these symptoms?
- A. Hepatic encephalopathy
- B. Hypoglycemia
- C. Electrolyte imbalance
- D. Dehydration
Correct answer: A
Rationale: Hepatic encephalopathy is the most likely condition causing confusion and disorientation in a client with liver cirrhosis. This condition is a common complication of liver cirrhosis and is characterized by cognitive impairment due to elevated ammonia levels in the blood. The build-up of ammonia affects brain function, leading to symptoms such as confusion, disorientation, and altered consciousness. Hypoglycemia (choice B) may present with confusion but is less likely in a client with liver cirrhosis without a history of diabetes or insulin use. Electrolyte imbalance (choice C) and dehydration (choice D) can contribute to confusion but are not the primary causes in a client with liver cirrhosis experiencing these symptoms.
2. A client with a history of diabetes mellitus is admitted with a foot ulcer. The nurse should recognize that which intervention is most critical in promoting healing of the foot ulcer?
- A. Strict control of blood glucose levels.
- B. Regular dressing changes with sterile technique.
- C. Application of antibiotic ointment.
- D. Hydrotherapy treatment daily.
Correct answer: A
Rationale: In diabetic clients with foot ulcers, strict control of blood glucose levels is essential for promoting wound healing. High blood glucose levels can impair circulation and compromise the body's ability to fight infection, delaying the healing process. By maintaining optimal blood glucose levels, the client's overall health and wound healing potential are improved.
3. A client with liver cirrhosis is prescribed lactulose. What is the purpose of this medication?
- A. To lower blood sugar levels
- B. To reduce ammonia levels
- C. To treat liver inflammation
- D. To improve bile flow
Correct answer: B
Rationale: Lactulose is prescribed to reduce ammonia levels in clients with liver cirrhosis. Elevated ammonia levels can lead to hepatic encephalopathy, a serious complication of liver cirrhosis. Lactulose works by acidifying the colon, which in turn traps ammonia in the colon and helps its elimination from the body through stool, thereby reducing the risk of hepatic encephalopathy. Choice A is incorrect because lactulose does not lower blood sugar levels. Choice C is incorrect as lactulose is not used to treat liver inflammation. Choice D is incorrect as lactulose does not improve bile flow.
4. A client is admitted with diabetic ketoacidosis (DKA). Which assessment finding requires immediate intervention?
- A. Fruity breath odor.
- B. Blood glucose of 450 mg/dL.
- C. Deep, rapid respirations.
- D. Serum potassium of 5.2 mEq/L.
Correct answer: C
Rationale: The correct answer is C: Deep, rapid respirations (Kussmaul breathing). This is a sign of severe acidosis commonly seen in diabetic ketoacidosis (DKA) and requires immediate intervention. Kussmaul breathing helps to compensate for the metabolic acidosis by blowing off carbon dioxide. Prompt intervention is necessary to prevent further deterioration and potential respiratory failure. Fruity breath odor (Choice A) is a classic sign of DKA but does not require immediate intervention. While a blood glucose level of 450 mg/dL (Choice B) is high, it does not pose an immediate threat to the client's life. Serum potassium of 5.2 mEq/L (Choice D) is slightly elevated but not the most critical finding that requires immediate intervention in this scenario.
5. What side effect should be monitored for in a patient with chronic heart failure taking spironolactone?
- A. Hypokalemia
- B. Hyperkalemia
- C. Hyponatremia
- D. Hypernatremia
Correct answer: B
Rationale: The correct answer is B: Hyperkalemia. Spironolactone is a potassium-sparing diuretic commonly used in patients with heart failure. One of the potential side effects of spironolactone therapy is hyperkalemia, which is an elevated level of potassium in the blood. Hyperkalemia can lead to serious cardiac arrhythmias, making it crucial for healthcare providers to monitor potassium levels closely. Choices A, C, and D are incorrect because hypokalemia (low potassium levels), hyponatremia (low sodium levels), and hypernatremia (high sodium levels) are not typically associated with spironolactone use in patients with chronic heart failure.
