Nursing Elites

1. A client with chronic kidney disease (CKD) is experiencing hyperkalemia. Which intervention should the nurse implement to address this condition?

• A. Administer calcium gluconate.
• B. Encourage a diet high in potassium.
• C. Provide potassium supplements.
• D. Restrict sodium intake.

Correct answer: A

Rationale: Administering calcium gluconate is the appropriate intervention for a client with hyperkalemia. Calcium gluconate helps stabilize the heart by counteracting the effects of high potassium levels and reducing the risk of cardiac complications in individuals with hyperkalemia. Choices B, C, and D are incorrect. Encouraging a diet high in potassium or providing potassium supplements would exacerbate hyperkalemia. Restricting sodium intake is not directly related to addressing hyperkalemia.

2. A 46-year-old man with a history of cirrhosis is brought in by his wife because he has been acting strangely. On examination, he is disoriented, ataxic, and has slurred speech. He is also hyperreflexic. His white blood cell count is normal. His hematocrit is 34%. Coagulation times are elevated. His ammonia level is normal. Which of the following statements regarding his management is correct?

• A. He should be treated with a low-protein diet and lactulose
• B. Lorazepam is not the drug of choice to control his behavior
• C. He should not be placed on gentamicin prophylactically to prevent the development of peritonitis
• D. If the patient complains of pain, acetaminophen should be avoided and nonsteroidal anti-inflammatory agents should be used

Correct answer: A

Rationale: This patient presents with symptoms consistent with hepatic encephalopathy. Despite having a normal ammonia level, he should be treated with lactulose and a low-protein diet as recommended for stage 2 hepatic encephalopathy. The normal ammonia level does not exclude the diagnosis, as it lacks sensitivity and specificity. Medications like lorazepam, gentamicin, and NSAIDs should be avoided due to their potential adverse effects in patients with liver disease. Acetaminophen should also be avoided in such patients.

3. The client with newly diagnosed osteoporosis is being taught by the nurse about dietary modifications. Which instruction should the nurse include?

• A. Increase your intake of high-calcium foods.
• B. Limit your intake of vitamin D-rich foods.
• C. Avoid foods high in phosphorus.
• D. Increase your intake of high-sodium foods.

Correct answer: A

Rationale: Increasing the intake of high-calcium foods is essential for improving bone density and managing osteoporosis. Calcium is a key mineral necessary for bone health, and individuals with osteoporosis often need higher levels of calcium to help strengthen their bones and prevent further bone loss. Therefore, advising the client to increase their intake of high-calcium foods is the most appropriate dietary modification to support their bone health.

4. 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.

5. A 35-year-old man presents with fatigue, weight loss, and hyperpigmentation of the skin. 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 clinical presentation of a 35-year-old man with fatigue, weight loss, hyperpigmentation of the skin, hyponatremia, hyperkalemia, and low cortisol levels is classic for Addison's disease. These findings are consistent with primary adrenal insufficiency, where the adrenal glands fail to produce adequate cortisol. In Addison's disease, the adrenal cortex is damaged, leading to decreased cortisol production and elevated levels of ACTH. This results in symptoms such as fatigue, weight loss, and hyperpigmentation due to increased ACTH production stimulating melanocytes. Hyponatremia and hyperkalemia are common electrolyte abnormalities seen in Addison's disease due to aldosterone deficiency. Therefore, the correct diagnosis in this case is Addison's disease.
