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 receiving intermittent bolus feedings via a nasogastric tube. In which position should the nurse place the client once the feeding is complete?

• A. Supine
• B. Head of bed flat
• C. Left lateral position
• D. Head of bed elevated 30 to 45 degrees

Correct answer: B

Rationale: After intermittent bolus feedings through a nasogastric tube, the correct position for the client is to keep the head of the bed flat. This position helps prevent vomiting and aspiration. Placing the client in a supine position (choice A) can increase the risk of aspiration. The left lateral position (choice C) is not typically used after nasogastric tube feedings. Elevating the head of the bed 30 to 45 degrees (choice D) is suitable for continuous tube feedings to reduce the risk of aspiration, but for intermittent bolus feedings, keeping the head of the bed flat is preferred to prevent regurgitation and aspiration.

3. A healthcare professional is reviewing the results of renal function testing in a client with renal calculi. Which finding indicates to the healthcare professional that the client’s blood urea nitrogen (BUN) level is within the normal range?

• A. 2 mg/dL
• B. 18 mg/dL
• C. 25 mg/dL
• D. 35 mg/dL

Correct answer: B

Rationale: The normal BUN ranges from 5 to 20 mg/dL. A BUN level of 18 mg/dL falls within this normal range. Values of 25 and 35 mg/dL are elevated, suggesting potential renal insufficiency. Choice A (2 mg/dL) is abnormally low and not indicative of a normal BUN level.

4. A client with heart disease is on a continuous telemetry monitor and has developed sinus bradycardia. In determining the possible cause of the bradycardia, the nurse assesses the client's medication record. Which medication is most likely the cause of the bradycardia?

• A. Propranolol (Inderal).
• B. Captopril (Capoten).
• C. Furosemide (Lasix).
• D. Dobutamine (Dobutrex).

Correct answer: A

Rationale: Propranolol (Inderal) is a beta-adrenergic blocking agent that acts to decrease heart rate and contractility. Sinus bradycardia is a common side effect of beta blockers due to their negative chronotropic effect on the heart. Captopril (Capoten) is an ACE inhibitor used for hypertension and heart failure, not associated with causing bradycardia. Furosemide (Lasix) is a loop diuretic that can lead to electrolyte imbalances but not commonly linked to bradycardia. Dobutamine (Dobutrex) is a beta-1 adrenergic agonist that increases heart rate and contractility, making it an unlikely cause of bradycardia in this scenario.

5. What information will the nurse provide when counseling a patient starting a sulfonamide drug for a urinary tract infection?

• A. Drink several quarts of water daily.
• B. If stomach upset occurs, avoid taking antacids.
• C. Limit sun exposure to avoid skin reactions.
• D. Report any sore throat promptly.

Correct answer: A

Rationale: The correct answer is A: Drink several quarts of water daily. This advice aims to prevent crystalluria, a potential side effect of sulfonamide drugs. Option B is incorrect because antacids should not be taken with sulfonamides as they can decrease drug absorption. Option C is incorrect as sulfonamides can increase sensitivity to sunlight, not requiring sun exposure limitations but sun protection measures. Option D is incorrect because a sore throat could indicate a more serious adverse effect and should be promptly reported for evaluation.
