Nursing Elites

1. The nurse is caring for a newly admitted patient who will receive digoxin to treat a cardiac dysrhythmia. The patient takes hydrochlorothiazide (HydroDIURIL) and reports regular use of over-the-counter laxatives. Before administering the first dose of digoxin, the nurse will review the patient’s electrolytes with careful attention to the levels of which electrolytes?

• A. Calcium and magnesium
• B. Sodium and calcium
• C. Potassium and chloride
• D. Potassium and magnesium

Correct answer: D

Rationale: Before administering digoxin, the nurse must review the patient's electrolyte levels, focusing on potassium and magnesium. Hypomagnesemia, similar to hypokalemia, can enhance the action of digitalis and lead to digitalis toxicity. Laxatives and diuretics, like hydrochlorothiazide, can deplete both potassium and magnesium. Therefore, monitoring these electrolytes is crucial to prevent potential adverse effects associated with digoxin therapy. Choice A (Calcium and magnesium) is incorrect because calcium levels are not specifically mentioned as crucial for digoxin therapy. Choice B (Sodium and calcium) is incorrect as sodium is not typically monitored in relation to digoxin therapy. Choice C (Potassium and chloride) is incorrect because although potassium is vital, chloride is not typically associated with digoxin therapy.

2. A client is experiencing diarrhea. For which acid-base disorder should the nurse assess the client?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: When a client experiences diarrhea, the loss of bicarbonate-rich fluids from the body leads to a decrease in the bicarbonate levels in the blood, resulting in metabolic acidosis. Metabolic alkalosis (choice B) is characterized by an increase in bicarbonate levels, which is not typically associated with diarrhea. Respiratory acidosis (choice C) is caused by retention of carbon dioxide, while respiratory alkalosis (choice D) results from excessive exhalation of carbon dioxide, neither of which are directly related to diarrhea. Therefore, the correct answer is metabolic acidosis (choice A) in the context of diarrhea.

3. After undergoing a renal biopsy, a client reports pain radiating to the front of the abdomen from the biopsy site. What finding should the nurse assess the client for?

• A. Bleeding
• B. Renal colic
• C. Infection at the site
• D. Increased temperature

Correct answer: A

Rationale: The correct answer is A: Bleeding. Pain radiating to the front of the abdomen from the renal biopsy site suggests bleeding, which should be promptly assessed and managed. Bleeding can lead to serious complications if not addressed timely. Renal colic (choice B) is associated with kidney stones and typically presents with severe flank pain. Infection at the site (choice C) would more likely present with localized signs such as redness, swelling, warmth, and tenderness. Increased temperature (choice D) alone is not specific to the issue described and may be indicative of various conditions.

4. The healthcare provider prescribes diagnostic tests for a client with pneumonia identified on a chest X-ray. Which diagnostic test should the nurse review for implementation to guide the most therapeutic treatment of pneumonia?

• A. Sputum culture and sensitivity
• B. Blood cultures
• C. Arterial blood gases (ABG)
• D. Computerized tomography (CT) of the chest

Correct answer: A

Rationale: Sputum culture and sensitivity is the most appropriate diagnostic test for pneumonia as it helps in identifying the causative organism, which is crucial for guiding the selection of the most effective antibiotic therapy. Blood cultures (choice B) are more useful in identifying systemic infections rather than pneumonia specifically. Arterial blood gases (ABG) (choice C) are helpful in assessing oxygenation but do not directly aid in identifying the causative organism. Computerized tomography (CT) of the chest (choice D) is useful for evaluating structural abnormalities in the lungs but is not the initial test of choice for diagnosing pneumonia.

5. The nurse is caring for several patients who are receiving antibiotics. Which order will the nurse question?

• A. Azithromycin (Zithromax) 500 mg IV in 500 mL of fluid
• B. Azithromycin (Zithromax) 500 mg PO once daily
• C. Erythromycin 300 mg IM QID
• D. Erythromycin 300 mg PO QID

Correct answer: C

Rationale: The nurse should question the order for Erythromycin 300 mg IM QID. Erythromycin and other macrolides should not be given intramuscularly because they cause painful tissue irritation. Options A and B are correct routes for Azithromycin, either intravenously or orally. Option D is a correct route for Erythromycin, which is orally.
