Nursing Elites

1. A patient with heart failure is prescribed digoxin. What is the most important instruction the nurse should provide?

• A. Take an extra dose if you miss one.
• B. Avoid high-potassium foods.
• C. Report any visual disturbances.
• D. Stop taking the medication if your pulse is normal.

Correct answer: C

Rationale: The correct answer is C: 'Report any visual disturbances.' Patients taking digoxin should be instructed to report any visual disturbances, as this can be a sign of digoxin toxicity. Visual disturbances like changes in color vision, blurred vision, or seeing halos around lights can indicate an overdose of digoxin. Choices A, B, and D are incorrect. Instructing a patient to take an extra dose if they miss one can lead to overdose. Avoiding high-potassium foods is important for patients on potassium-sparing diuretics, not digoxin. Stopping the medication if the pulse is normal is incorrect, as the pulse rate alone is not an indicator of digoxin effectiveness or toxicity.

2. What health promotion teaching should prioritize to prevent drug-induced hepatitis?

• A. Finish all prescribed courses of antibiotics, regardless of symptom resolution
• B. Adhere to dosing recommendations of over-the-counter analgesics
• C. Ensure that expired medications are disposed of safely
• D. Ensure that pharmacists regularly review drug regimens for potential interactions

Correct answer: B

Rationale: Adhering to dosing recommendations of over-the-counter analgesics is crucial in preventing drug-induced hepatitis. Overdosing on analgesics can lead to liver damage, making it essential to follow the recommended dosages to reduce the risk of hepatotoxicity.

3. When assessing a client reporting severe pain in the right lower quadrant of the abdomen, which sign would most likely indicate appendicitis?

• A. Rebound tenderness at McBurney's point.
• B. Positive Murphy's sign.
• C. Rovsing's sign.
• D. Cullen's sign.

Correct answer: A

Rationale: Rebound tenderness at McBurney's point is a classic sign of appendicitis. This sign indicates peritoneal irritation, a common feature of appendicitis. McBurney's point is located in the right lower quadrant of the abdomen and is a focal point for assessing tenderness. Positive Murphy's sign is associated with cholecystitis, not appendicitis. Rovsing's sign is elicited by palpation of the left lower quadrant resulting in pain in the right lower quadrant, also suggestive of appendicitis. Cullen's sign is associated with acute pancreatitis and manifests as periumbilical ecchymosis.

4. 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.

5. The patient has a calcium level of 12.1 mg/dL. Which nursing action should the nurse include on the care plan?

• A. Maintain the patient on bed rest.
• B. Auscultate lung sounds every 4 hours.
• C. Monitor for Trousseau's and Chvostek's signs.
• D. Encourage fluid intake up to 4000 mL every day.

Correct answer: D

Rationale: The correct action for the nurse to include on the care plan for a patient with a calcium level of 12.1 mg/dL is to encourage fluid intake up to 4000 mL every day. This is essential to decrease the risk for renal calculi associated with hypercalcemia. While bed rest is not necessary, ambulation is encouraged to help decrease the loss of calcium from the bone. Monitoring for Trousseau's and Chvostek's signs is more relevant when hypocalcemia is suspected. Auscultating lung sounds every shift is a routine assessment, not required every 4 hours unless there is a specific respiratory concern.
