Nursing Elites

1. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?

• A. Losartan
• B. Spironolactone
• C. Metoprolol
• D. Furosemide

Correct answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.

2. A client with hypertension is prescribed a low-sodium diet. What is the most important instruction for the nurse to provide?

• A. Limit sodium intake to 2 grams per day.
• B. Choose fresh fruits and vegetables.
• C. Drink at least 8 glasses of water daily.
• D. Avoid processed foods and canned soups.

Correct answer: D

Rationale: The correct answer is D. Avoiding processed foods and canned soups is crucial for a client with hypertension on a low-sodium diet because these foods are typically high in sodium content. Fresh fruits and vegetables are generally healthy choices but may still contain some natural sodium. While limiting sodium intake to 2 grams per day is important, specifically avoiding processed foods and canned soups is more critical in this situation. Drinking water is essential for overall health but is not the most important instruction when focusing on reducing sodium intake.

3. A male client reports numbness and tingling in his fingers and around his mouth. What laboratory value should the nurse review?

• A. Capillary glucose.
• B. Serum calcium.
• C. Urine specific gravity.
• D. White blood cell count.

Correct answer: B

Rationale: The correct answer is B, Serum calcium. Numbness and tingling in the fingers and around the mouth are indicative of hypocalcemia, a condition characterized by low calcium levels in the blood. Reviewing the client's serum calcium levels is crucial in this situation to assess for hypocalcemia. Choice A, Capillary glucose, is incorrect because symptoms described are not typically associated with glucose abnormalities. Choice C, Urine specific gravity, and Choice D, White blood cell count, are unrelated to the symptoms presented and are not indicative of the client's condition.

4. After placing a stethoscope to auscultate S1 and S2 heart sounds, what should the nurse do to check for an S3 heart sound?

• A. Switch to the diaphragm of the stethoscope to hear any abnormal sounds
• B. Listen with the bell of the stethoscope at the same location
• C. Listen at a different location over the aortic area
• D. Switch to the apical area and reassess for S3 sounds

Correct answer: B

Rationale: To assess for an S3 heart sound, the nurse should listen with the bell of the stethoscope. An S3 heart sound is often low-pitched and best heard with the bell. Choice A is incorrect because switching to the diaphragm is not ideal for detecting low-pitched sounds like an S3. Choice C is incorrect as the S3 heart sound is best heard over the apex of the heart, not the aortic area. Choice D is incorrect because moving to the apical area is appropriate, but the nurse should specifically use the bell of the stethoscope to listen for S3 sounds.

5. A client with pneumonia is receiving oxygen therapy. What assessment finding requires immediate intervention?

• A. Increased oxygen saturation of 96%.
• B. Oxygen saturation of 89%.
• C. Respiratory rate of 20 breaths per minute.
• D. Decreased heart rate of 70 beats per minute.

Correct answer: B

Rationale: The correct answer is B. An oxygen saturation of 89% indicates hypoxemia, which is below the normal range (usually 95-100%). This finding requires immediate intervention as it signifies inadequate oxygenation. Options A, C, and D are within normal limits and do not indicate an urgent need for intervention. Option A indicates a good oxygen saturation level, option C denotes a normal respiratory rate, and option D suggests a normal heart rate. Therefore, these options do not require immediate intervention compared to the critically low oxygen saturation level of 89% in option B.
