Nursing Elites

1. A patient with chronic heart failure is prescribed furosemide. What is the primary action of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: B

Rationale: Furosemide is a loop diuretic that acts by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased diuresis. By reducing fluid retention, furosemide helps decrease the workload on the heart in patients with chronic heart failure. This medication does not directly increase cardiac output, decrease heart rate, or lower blood pressure as its primary action.

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. The nurse is caring for four clients: Client A, who has emphysema and an oxygen saturation of 94%; Client B, with a postoperative hemoglobin of 8.7 g/dL; Client C, newly admitted with a potassium level of 3.8 mEq/L; and Client D, scheduled for an appendectomy with a white blood cell count of 15,000/mm3. What intervention should the nurse implement?

• A. Increase Client A's oxygen to 4 liters per minute via nasal cannula.
• B. Determine if Client B has two units of packed cells available in the blood bank.
• C. Ask the dietitian to add a banana to Client C's breakfast tray.
• D. Inform Client D that surgery is likely to be delayed until the infection is treated.

Correct answer: D

Rationale: A high white blood cell count, as seen in Client D, indicates infection, which may require postponing surgery to treat the infection adequately. It is crucial to address the underlying infection before proceeding with the appendectomy to prevent complications and ensure a successful surgical outcome.

4. An 82-year-old woman with no past medical history presents to your clinic complaining of arthritic symptoms. She is not taking any medications but needs something for her arthritis. You want to start her on a nonsteroidal anti-inflammatory drug (NSAID) but are concerned about her age and the risk of peptic ulcers. As she has to pay for her medications out-of-pocket and requests the most cost-effective option, what is the most appropriate treatment plan?

• A. Prescribe an inexpensive NSAID alone
• B. Prescribe an inexpensive NSAID and misoprostol
• C. Prescribe celecoxib
• D. Prescribe an inexpensive NSAID and sucralfate

Correct answer: A

Rationale: In this scenario, the most appropriate treatment plan would be to prescribe an inexpensive NSAID alone. While the elderly woman is at a higher risk of developing NSAID-related toxicity, prophylaxis with misoprostol or sucralfate is not recommended in the absence of a history of peptic ulcer disease or abdominal symptoms. Celecoxib, a selective COX-2 inhibitor, may be a more expensive option than traditional NSAIDs. Considering the patient's preference for the most inexpensive option and the lack of specific risk factors, starting with a standalone NSAID is the most suitable approach.

5. A client with cirrhosis of the liver is being cared for by the healthcare team. Which clinical manifestation indicates that the client has developed hepatic encephalopathy?

• A. Asterixis.
• B. Jaundice.
• C. Ascites.
• D. Splenomegaly.

Correct answer: A

Rationale: Asterixis, also known as flapping tremor, is a characteristic sign of hepatic encephalopathy, a severe complication of liver cirrhosis. Hepatic encephalopathy results from the liver's inability to detoxify substances in the body, leading to neurologic manifestations such as changes in mental status, confusion, and asterixis.
