Nursing Elites

1. Which lab value is most critical to monitor in a patient receiving digoxin?

• A. Monitor potassium levels
• B. Monitor sodium levels
• C. Monitor calcium levels
• D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels in a patient receiving digoxin. Hypokalemia can potentiate the toxic effects of digoxin, leading to serious cardiac arrhythmias. Monitoring potassium levels helps prevent toxicity. Monitoring sodium levels (Choice B), calcium levels (Choice C), and magnesium levels (Choice D) are also important aspects of patient care, but potassium levels are most critical in patients on digoxin therapy.

2. A nurse is reviewing the laboratory results of a client who has rheumatoid arthritis and is prescribed methotrexate. Which of the following results should the nurse report to the provider?

• A. White blood cell count 8,000/mm3
• B. Platelet count 150,000/mm3
• C. Hemoglobin 14 g/dL
• D. Aspartate aminotransferase (AST) 60 units/L

Correct answer: D

Rationale: The correct answer is D: Aspartate aminotransferase (AST) 60 units/L. An elevated AST level indicates liver damage, a side effect of methotrexate, and should be reported. Choices A, B, and C are within normal ranges and do not indicate potential complications related to methotrexate therapy.

3. A nurse is assessing a client who is receiving morphine via a patient-controlled analgesia (PCA) pump. Which of the following findings should the nurse report to the provider?

• A. Respiratory rate of 20/min
• B. Oxygen saturation of 93%
• C. Pain level of 2 on a scale of 0 to 10
• D. Blood pressure of 110/70 mm Hg

Correct answer: D

Rationale: The correct answer is D because a blood pressure drop or other signs of morphine overdose should be reported, especially when using a PCA pump. Choices A, B, and C are within normal limits and do not indicate an immediate concern related to morphine administration.

4. A client who is at 36 weeks of gestation is scheduled for a nonstress test (NST). Which of the following statements by the client indicates an understanding of the teaching?

• A. I should fast for 12 hours before the test.
• B. I should expect the test to take about 10 minutes.
• C. I should have a full bladder for this test.
• D. I will need to have my blood glucose checked before the test.

Correct answer: B

Rationale: The correct answer is B. The nonstress test typically takes about 10 minutes and evaluates the fetal heart rate in response to fetal movement. Having a full bladder or fasting for 12 hours is not required for a nonstress test. Checking blood glucose levels is not part of the nonstress test procedure.

5. A nurse is caring for a client who has an indwelling urinary catheter. Which of the following interventions should the nurse implement to prevent catheter-associated infections?

• A. Change the catheter every 24 hours
• B. Ensure the drainage bag is positioned above the bladder
• C. Perform routine irrigation of the catheter
• D. Empty the drainage bag every 4 hours

Correct answer: B

Rationale: The correct answer is to ensure the drainage bag is positioned above the bladder. This positioning prevents urine reflux into the bladder, reducing the risk of catheter-associated infections. Changing the catheter too frequently (Choice A) can actually increase the risk of infection by introducing pathogens. Performing routine catheter irrigation (Choice C) is no longer recommended as it can increase the risk of infection by introducing bacteria. Emptying the drainage bag every 4 hours (Choice D) is a standard practice to prevent urinary stasis but is not directly related to preventing catheter-associated infections.
