Nursing Elites

1. The nurse administers an antibiotic for a respiratory tract infection. To evaluate the medication's effectiveness, which laboratory values should the nurse monitor?

• A. Platelet count and red blood cell count.
• B. White blood cell count and sputum culture.
• C. Hemoglobin A1c and glucose tolerance test.
• D. Arterial blood gases and serum electrolytes.

Correct answer: B

Rationale: The correct answer is B: White blood cell count and sputum culture. Monitoring white blood cell count and sputum cultures is essential to assess the effectiveness of the antibiotic in treating the respiratory tract infection. Changes in white blood cell count can indicate the body's response to infection, while sputum cultures help determine if the antibiotic is targeting the specific pathogens causing the infection. Choices A, C, and D are incorrect because platelet count, red blood cell count, hemoglobin A1c, glucose tolerance test, arterial blood gases, and serum electrolytes are not directly related to evaluating the effectiveness of an antibiotic in treating a respiratory tract infection.

2. 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.

3. An older client with a long history of coronary artery disease, HTN, and HF arrives in the ED in respiratory distress. The healthcare provider prescribes furosemide IV. Which therapeutic response to furosemide should the nurse expect in the client with acute HF?

• A. Decreased heart rate
• B. Improved blood pressure
• C. Increased urine output
• D. Reduced preload

Correct answer: D

Rationale: The correct answer is D: Reduced preload. Furosemide is a diuretic that reduces fluid overload in heart failure, which lowers the preload (the volume of blood in the ventricles before contraction). By reducing this volume, furosemide improves symptoms of heart failure. While furosemide may lead to increased urine output and lower blood pressure, these effects are secondary to the reduction in preload. Decreased heart rate is not a direct effect of furosemide in heart failure.

4. At 0600 while admitting a woman for a scheduled repeat cesarean section, the client tells the nurse that she drank a cup of coffee at 0400 because she wanted to avoid getting a headache. Which action should the nurse take first?

• A. Cancel the surgery
• B. Inform the anesthesia care provider
• C. Ask the client if she has had any other liquids
• D. Proceed with routine preparations

Correct answer: B

Rationale: Drinking liquids before surgery can increase the risk of aspiration during anesthesia. Therefore, the anesthesia care provider must be informed immediately to determine how to proceed, as this could delay or alter the surgical plan. Canceling the surgery without consulting the anesthesia care provider would be premature and could potentially lead to unnecessary actions. Asking the client if she has had any other liquids is important but not the first priority. Proceeding with routine preparations without addressing the potential issue of ingesting liquids before surgery could compromise the client's safety.

5. In assessing an adult client with a partial rebreather mask, the nurse notes that the oxygen reservoir bag does not deflate completely during inspiration and the client’s respiratory rate is 14 breaths/minute. What action should the nurse implement?

• A. Remove the mask immediately
• B. Document the assessment data
• C. Increase the oxygen flow
• D. Increase the respiratory rate setting

Correct answer: B

Rationale: The correct answer is to document the assessment data. In a partial rebreather mask, it is normal for the oxygen reservoir bag not to deflate completely during inspiration. Additionally, a respiratory rate of 14 breaths/minute falls within the normal range. Therefore, these findings indicate that the mask is functioning as intended. Removing the mask immediately is unnecessary as there are no signs of distress. Increasing the oxygen flow or adjusting the respiratory rate setting is not warranted based on the assessment findings, as they are within normal parameters.
