1. 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.
2. A 70-year-old woman presents with fatigue, anorexia, and weight loss. She has noticed darkening of her skin, particularly in sun-exposed areas. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?
- A. Cushing's syndrome
- B. Addison's disease
- C. Hypothyroidism
- D. Pheochromocytoma
Correct answer: B
Rationale: The combination of symptoms such as fatigue, anorexia, weight loss, hyperpigmentation of the skin, along with hyponatremia, hyperkalemia, and low cortisol levels, points towards Addison's disease. This condition is characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production.
3. A 65-year-old woman presents with difficulty swallowing, weight loss, and a history of long-standing heartburn. She has been on proton-pump inhibitors for years, but her symptoms have worsened. What is the most likely diagnosis?
- A. Peptic stricture
- B. Esophageal cancer
- C. Achalasia
- D. Esophageal spasm
Correct answer: B
Rationale: The presentation of difficulty swallowing, weight loss, and worsening symptoms despite long-term use of proton-pump inhibitors raises suspicion for esophageal cancer, especially in a patient with a history of chronic heartburn. Esophageal cancer should be considered in this scenario due to the concerning symptoms and lack of improvement despite appropriate medical management.
4. A client with newly diagnosed diabetes mellitus is being discharged home. Which statement indicates the client understands the instructions about managing blood glucose levels?
- A. I will test my blood glucose level once a week.
- B. I should eat a snack if my blood glucose is 70 mg/dl.
- C. If I feel shaky, I should take another dose of insulin.
- D. It's okay to skip a meal if I'm not hungry.
Correct answer: B
Rationale: Choice B is the correct answer. Eating a snack when blood glucose is low (70 mg/dl) can help prevent hypoglycemia. It is important for clients with diabetes to manage their blood glucose levels to prevent complications, and consuming a snack when glucose levels drop can help maintain the balance.
5. A client has developed hepatic encephalopathy secondary to cirrhosis and is receiving care on the medical unit. The client's current medication regimen includes lactulose four times daily. What desired outcome should the nurse relate to this pharmacologic intervention?
- A. Two to three soft bowel movements daily
- B. Significant increase in appetite and food intake
- C. Absence of nausea and vomiting
- D. Absence of blood or mucus in stool
Correct answer: A
Rationale: Lactulose is used in hepatic encephalopathy to reduce blood ammonia levels by promoting bowel movements. The desired outcome of lactulose therapy is typically two to three soft bowel movements daily, which helps in eliminating excess ammonia from the body, thus improving the client's condition.
