Nursing Elites

1. After placing a stethoscope as seen in the picture, the nurse auscultates S1 and S2 heart sounds. To determine if an S3 heart sound is present, what action should the nurse take first?

• A. Slide the stethoscope across the sternum.
• B. Move the stethoscope to the mitral site.
• C. Listen with the bell at the same location.
• D. Observe the cardiac telemetry monitor.

Correct answer: C

Rationale: The nurse uses the bell of the stethoscope to hear low-pitched sounds such as S3 and S4. To determine if an S3 heart sound is present, the nurse should listen at the same location using the bell first. This allows for the accurate identification of low-pitched sounds. Moving the stethoscope across the sternum (Choice A) or to the mitral site (Choice B) would not be the initial actions to assess for an S3 heart sound. Observing the cardiac telemetry monitor (Choice D) is not relevant for assessing S3 heart sounds, as it does not provide direct auscultation of heart sounds.

2. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum calcium level

Correct answer: A

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, the nurse should closely monitor the serum potassium level. Erythropoietin therapy can increase red blood cell production, leading to a higher demand for potassium. Monitoring potassium levels is crucial to prevent hyperkalemia, a potential risk associated with this therapy. Hemoglobin level (Choice B) is important to assess the effectiveness of erythropoietin therapy, but monitoring potassium levels takes precedence due to the risk of hyperkalemia. White blood cell count (Choice C) and serum calcium level (Choice D) are not directly affected by erythropoietin therapy in the context of chronic kidney disease.

3. The nurse is caring for a client with acute kidney injury (AKI) secondary to gentamicin therapy. The client's serum blood potassium is elevated. Which finding requires immediate action by the nurse?

• A. Anuria for the last 12 hours.
• B. Tachycardia and hypotension.
• C. Decreased urine output.
• D. Elevated blood urea nitrogen (BUN) levels.

Correct answer: A

Rationale: The correct answer is A. Anuria for the last 12 hours. Anuria, the absence of urine output, indicates complete kidney failure and is a medical emergency that requires immediate attention. In acute kidney injury (AKI), the kidneys are unable to filter waste from the blood effectively, leading to a buildup of toxins and electrolyte imbalances like elevated blood potassium levels. Tachycardia and hypotension (choice B) can be seen in AKI but do not reflect the urgency of addressing anuria. Decreased urine output (choice C) is concerning but not as critical as the absence of urine production. Elevated blood urea nitrogen (BUN) levels (choice D) are indicative of kidney dysfunction but do not demand immediate action as anuria does.

4. Before a dressing change to his legs, which intervention is most important for the nurse to implement?

• A. Encourage the patient to stay at the bedside
• B. Use distraction techniques to reduce pain
• C. Maintain strict aseptic technique
• D. Place a drape over the burn area

Correct answer: C

Rationale: Maintaining strict aseptic technique is crucial before a dressing change for burn patients to prevent infection. Encouraging the patient to stay at the bedside, using distraction techniques, or placing a drape over the burn area are not as critical as ensuring asepsis in this situation.

5. In caring for a client with a PCA infusion of morphine sulfate through the right cephalic vein, the nurse assesses that the client is lethargic with a blood pressure of 90/60, pulse rate of 118 beats per minute, and respiratory rate of 8 breaths per minute. What assessment should the nurse perform next?

• A. Note the appearance and patency of the client's peripheral IV site.
• B. Palpate the volume of the client's right radial pulse.
• C. Auscultate the client's breath sounds bilaterally.
• D. Observe the amount and dose of morphine in the PCA pump syringe.

Correct answer: D

Rationale: In this scenario, the nurse is dealing with a lethargic client with concerning vital signs after a PCA infusion of morphine sulfate. The next assessment the nurse should perform is to observe the amount and dose of morphine in the PCA pump syringe. This is crucial to evaluate for possible overdose, as the client's symptoms could be indicative of opioid toxicity. Checking the morphine amount and dose will help the nurse adjust the treatment accordingly. Choices A, B, and C do not directly address the potential cause of the client's lethargy and abnormal vital signs related to the morphine infusion.
