Nursing Elites

1. 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.

2. 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.

3. In a client with liver cirrhosis experiencing confusion and disorientation, what condition is most likely causing these symptoms?

• A. Hepatic encephalopathy
• B. Hypoglycemia
• C. Electrolyte imbalance
• D. Dehydration

Correct answer: A

Rationale: Hepatic encephalopathy is the most likely condition causing confusion and disorientation in a client with liver cirrhosis. This condition is a common complication of liver cirrhosis and is characterized by cognitive impairment due to elevated ammonia levels in the blood. The build-up of ammonia affects brain function, leading to symptoms such as confusion, disorientation, and altered consciousness. Hypoglycemia (choice B) may present with confusion but is less likely in a client with liver cirrhosis without a history of diabetes or insulin use. Electrolyte imbalance (choice C) and dehydration (choice D) can contribute to confusion but are not the primary causes in a client with liver cirrhosis experiencing these symptoms.

4. A client who is acutely ill has vigilant oral care included in their plan of care. What factor increases this client's risk for dental caries?

• A. Hormonal changes induced by the stress response leading to an acidic oral environment
• B. Systemic infections commonly affecting the teeth
• C. Intravenous hydration lacking fluoride
• D. Inadequate nutrition and reduced saliva production contributing to cavities

Correct answer: D

Rationale: Inadequate nutrition and decreased saliva production can lead to a conducive environment for the development of dental caries. Without proper nutrition and sufficient saliva, the protective mechanisms against cavities are compromised, making the individual more susceptible to tooth decay.

5. A client reports recent exposure to hepatitis A. What is a common mode of transmission for this virus?

• A. Blood transfusion
• B. Fecal-oral route
• C. Needle sharing
• D. Sexual contact

Correct answer: B

Rationale: Hepatitis A is commonly transmitted through the fecal-oral route, often via ingestion of contaminated food or water. This mode of transmission is why proper hygiene, sanitation, and vaccination are essential in preventing the spread of hepatitis A.
