Nursing Elites

1. The nurse is caring for a client who is postoperative following a thyroidectomy. Which laboratory value should be monitored closely?

• A. Serum calcium of 8.5 mg/dL
• B. Serum sodium of 136 mEq/L
• C. Serum potassium of 3.0 mEq/L
• D. Serum chloride of 102 mEq/L

Correct answer: C

Rationale: A serum potassium level of 3.0 mEq/L should be monitored closely in a client who is postoperative following a thyroidectomy to detect any electrolyte imbalances. After a thyroidectomy, there is a risk of hypokalemia due to the effects of anesthesia, stress response, and the surgical procedure itself. Monitoring serum potassium levels is crucial as hypokalemia can lead to cardiac arrhythmias and muscle weakness. Serum calcium, sodium, and chloride levels are important but not the primary focus following a thyroidectomy, making them incorrect choices.

2. The healthcare provider is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which clinical finding is most concerning?

• A. Increased fatigue
• B. Elevated blood pressure
• C. Elevated hemoglobin
• D. Low urine output

Correct answer: B

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, elevated blood pressure is the most concerning finding. Elevated blood pressure can indicate worsening hypertension, which requires immediate intervention to prevent further damage to the kidneys and other organs. Increased fatigue (choice A) is a common symptom in CKD but may not be as acutely concerning as elevated blood pressure. Elevated hemoglobin (choice C) can be an expected outcome of erythropoietin therapy and is not necessarily concerning. Low urine output (choice D) is important to monitor in CKD but may not be as immediately concerning as elevated blood pressure in this context.

3. 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.

4. The nurse plans to administer a scheduled dose of metoprolol (Toprol SR) at 0900 to a client with hypertension. At 0800, the nurse notes that the client's telemetry pattern shows a second-degree heart block with a ventricular rate of 50. What action should the nurse take?

• A. Administer the Toprol immediately and monitor the client until the heart rate increases.
• B. Provide the dose of Toprol as scheduled and assign a UAP to monitor the client's BP q30 minutes.
• C. Give the Toprol as scheduled if the client's systolic blood pressure reading is greater than 180.
• D. Hold the scheduled dose of Toprol and notify the healthcare provider of the telemetry pattern.

Correct answer: D

Rationale: In clients with second-degree heart block, beta blockers such as metoprolol (Toprol SR) are contraindicated as they can further decrease the heart rate. Administering metoprolol in this situation can lead to serious complications. The correct action for the nurse to take is to hold the scheduled dose of Toprol and promptly notify the healthcare provider of the telemetry pattern. This ensures patient safety and appropriate management of the cardiac condition. Choices A, B, and C are incorrect because administering Toprol despite the heart block can worsen the condition and pose a risk to the client's health.

5. The nurse is caring for 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: The correct answer is A: Serum potassium level. When a client with chronic kidney disease (CKD) is receiving erythropoietin therapy, the nurse should closely monitor the serum potassium level. Erythropoietin therapy can stimulate red blood cell production, leading to an increased demand for potassium. This increases the risk of hyperkalemia, making it crucial to monitor potassium levels closely. Choices B, C, and D are incorrect because erythropoietin therapy primarily affects red blood cell production, not hemoglobin, white blood cell count, or serum calcium levels.
