Nursing Elites

1. A patient with chronic kidney disease (CKD) is prescribed calcium acetate. What is the primary purpose of this medication?

• A. Treat hyperkalemia
• B. Reduce phosphate levels
• C. Lower blood pressure
• D. Increase hemoglobin levels

Correct answer: B

Rationale: The primary purpose of prescribing calcium acetate to a patient with chronic kidney disease (CKD) is to reduce phosphate levels. Calcium acetate binds to dietary phosphate, preventing its absorption and helping to manage hyperphosphatemia commonly seen in CKD patients.

2. A client's health history is suggestive of inflammatory bowel disease. Which of the following would suggest Crohn disease, rather than ulcerative colitis, as the cause of the client's signs and symptoms?

• A. A pattern of distinct exacerbations and remissions
• B. Severe diarrhea
• C. An absence of blood in stool
• D. Involvement of the rectal mucosa

Correct answer: C

Rationale: In the context of inflammatory bowel disease, the absence of blood in stool is more indicative of Crohn disease. Crohn disease typically presents with non-bloody stools, while ulcerative colitis often involves bloody stools due to continuous mucosal inflammation confined to the colon and rectum.

3. What is the primary action of amlodipine when prescribed to a patient with hypertension?

• A. Increase heart rate
• B. Reduce blood pressure
• C. Lower cholesterol levels
• D. Decrease blood sugar levels

Correct answer: B

Rationale: Amlodipine is a calcium channel blocker that works by relaxing the blood vessels, leading to a reduction in blood pressure. This medication does not increase heart rate, lower cholesterol levels, or decrease blood sugar levels.

4. A 48-year-old man presents with fatigue, weight gain, and cold intolerance. Laboratory tests reveal high TSH and low free T4 levels. What is the most likely diagnosis?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Thyroiditis
• D. Thyroid cancer

Correct answer: A

Rationale: The scenario describes a classic presentation of hypothyroidism, supported by the laboratory findings of high TSH and low free T4 levels. In hypothyroidism, the body's thyroid hormone levels are inadequate, leading to symptoms like fatigue, weight gain, and cold intolerance. High TSH is a compensatory mechanism by the body to increase thyroid hormone production, which is deficient, resulting in a negative feedback loop. Therefore, the correct answer is hypothyroidism.

5. The nurse is planning care for a client with cirrhosis of the liver. Which intervention should the nurse include to reduce the risk of bleeding?

• A. Monitor for signs of infection.
• B. Limit the client's dietary protein intake.
• C. Administer vitamin K as prescribed.
• D. Encourage the client to increase fluid intake.

Correct answer: C

Rationale: Administering vitamin K as prescribed can help reduce the risk of bleeding in clients with cirrhosis by promoting clotting factor production. Cirrhosis often leads to impaired liver function, affecting the synthesis of clotting factors. Vitamin K supplementation helps in the production of these essential clotting factors, thus reducing the risk of bleeding in clients with cirrhosis. Monitoring for signs of infection (Choice A) is important for overall care but not directly related to reducing the risk of bleeding in cirrhosis. Limiting dietary protein intake (Choice B) may be necessary in some cases of cirrhosis but does not directly address the risk of bleeding. Encouraging increased fluid intake (Choice D) is beneficial for various aspects of health but does not specifically target the risk of bleeding in cirrhosis.
