1. Why is a low-protein diet recommended for a client with hepatic encephalopathy?
- A. Hyperglycemia
- B. Hypoglycemia
- C. Increased ammonia levels
- D. Electrolyte imbalance
Correct answer: C
Rationale: A low-protein diet is recommended for clients with hepatic encephalopathy to reduce ammonia levels. Ammonia, a byproduct of protein metabolism, can accumulate in the blood due to impaired liver function. Elevated ammonia levels can lead to worsening hepatic encephalopathy, a condition characterized by cognitive and neurological disturbances. Therefore, by limiting protein intake, the production of ammonia is reduced, thereby helping to manage hepatic encephalopathy. Choices A, B, and D are incorrect because hepatic encephalopathy is not primarily related to hyperglycemia, hypoglycemia, or electrolyte imbalance. The focus is on reducing ammonia levels to improve the condition.
2. A patient with a diagnosis of peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?
- A. With meals
- B. At bedtime
- C. Before meals
- D. After meals
Correct answer: C
Rationale: Omeprazole is best taken before meals for optimal effectiveness in reducing stomach acid production and promoting ulcer healing. Taking it before meals allows the medication to act on the proton pumps before food intake triggers acid production, thereby maximizing its therapeutic benefits. Choices A, B, and D are incorrect because taking omeprazole with meals, at bedtime, or after meals may not align with its mechanism of action, potentially reducing its effectiveness in managing peptic ulcer disease.
3. In a patient with chronic kidney disease (CKD) receiving erythropoietin therapy, what laboratory result should the nurse monitor to evaluate the effectiveness of this therapy?
- A. Serum creatinine
- B. White blood cell count
- C. Hemoglobin level
- D. Serum potassium
Correct answer: C
Rationale: The correct answer is C: Hemoglobin level. Erythropoietin therapy is used to stimulate red blood cell production in patients with chronic kidney disease who often develop anemia due to reduced erythropoietin production by the kidneys. Monitoring the hemoglobin level is essential to evaluate the effectiveness of erythropoietin therapy as an increase in hemoglobin indicates improved red blood cell production and better management of anemia in these patients. Serum creatinine, white blood cell count, and serum potassium levels are important parameters to monitor in CKD patients but are not specific indicators of the effectiveness of erythropoietin therapy for managing anemia.
4. A client with liver cirrhosis and ascites is being treated with spironolactone. What is a key nursing consideration for this medication?
- A. Monitoring for signs of hyperkalemia
- B. Checking for signs of hypoglycemia
- C. Assessing for signs of dehydration
- D. Observing for symptoms of hyponatremia
Correct answer: A
Rationale: Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia as it helps retain potassium in the body. Therefore, monitoring for signs of hyperkalemia such as muscle weakness, arrhythmias, or ECG changes is crucial to prevent potential complications.
5. A client with cirrhosis is at risk for bleeding. Which laboratory test is most important to monitor?
- A. Blood glucose
- B. Serum creatinine
- C. Prothrombin time (PT)
- D. Electrolytes
Correct answer: C
Rationale: In clients with cirrhosis, monitoring the Prothrombin time (PT) is crucial as it assesses the blood's ability to clot. Cirrhosis can lead to impaired liver function, affecting the synthesis of clotting factors, hence increasing the risk of bleeding. Maintaining a close watch on PT levels helps in timely intervention to prevent excessive bleeding episodes. Blood glucose (Choice A) is not directly related to the clotting function; serum creatinine (Choice B) and electrolytes (Choice D) are important, but in cirrhosis, monitoring PT takes precedence due to the increased bleeding risk.
