Nursing Elites

1. A healthcare provider is reviewing the laboratory report of a client with a prescription for digoxin. Which result requires withholding the medication?

• A. Digoxin 0.8 ng/mL
• B. Sodium 145 mEq/L
• C. BUN 20 mg/dL
• D. Potassium 3.1 mEq/L

Correct answer: D

Rationale: The correct answer is D. A low potassium level (3.1 mEq/L) can increase the risk of digoxin toxicity. Hypokalemia can potentiate the effects of digoxin on the heart, leading to serious dysrhythmias. Choices A, B, and C are within normal ranges and do not indicate a need to withhold digoxin.

2. A client with diabetes mellitus is experiencing hypoglycemia. Which of the following findings should the nurse expect?

• A. Polyuria
• B. Warm, dry skin
• C. Irritability
• D. Hyperventilation

Correct answer: C

Rationale: Irritability is a common finding in clients with hypoglycemia due to decreased glucose levels in the brain. Polyuria (excessive urination) is not typically associated with hypoglycemia, but rather with hyperglycemia. Warm, dry skin is not a typical finding in hypoglycemia; instead, the skin may be cool and clammy. Hyperventilation is not a common finding in hypoglycemia; instead, shallow breathing or difficulty breathing may occur.

3. A client with heart failure is prescribed furosemide. What finding should the nurse report to the provider?

• A. Sodium 140 mEq/L
• B. Heart rate of 82/min
• C. Potassium level of 2.8 mEq/L
• D. Oxygen saturation 95%

Correct answer: C

Rationale: The correct answer is C. A potassium level of 2.8 mEq/L is low and should be reported to the provider. Furosemide can cause potassium depletion, leading to hypokalemia. Low potassium levels can result in cardiac dysrhythmias, which is a serious concern in clients with heart failure. Choices A, B, and D are within normal ranges and do not require immediate reporting. Sodium level of 140 mEq/L, heart rate of 82/min, and oxygen saturation of 95% are all acceptable findings.

4. How should a healthcare professional assess for infection in a patient post-surgery?

• A. Check the surgical site
• B. Check for fever
• C. Check for abnormal breath sounds
• D. Check the patient's skin color

Correct answer: A

Rationale: When assessing for infection in a patient post-surgery, checking the surgical site is crucial. Changes in the appearance of the surgical site, such as redness, swelling, warmth, or drainage, can indicate an infection. While checking for fever (Choice B) is also important as it can be a sign of infection, it is a more general symptom and may not always be present. Checking for abnormal breath sounds (Choice C) and skin color (Choice D) are not typically direct indicators of infection in a post-surgery patient.

5. A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Serum potassium
• B. Platelets
• C. aPTT
• D. INR

Correct answer: C

Rationale: The correct answer is C: aPTT. Monitoring the activated partial thromboplastin time (aPTT) is crucial when a client is receiving heparin therapy. The aPTT reflects the clotting time and helps assess the effectiveness of heparin in preventing clot formation. Keeping the aPTT within the therapeutic range ensures that the medication is working optimally. Choices A, B, and D are incorrect because serum potassium, platelets, and INR are not direct indicators of heparin's effectiveness or therapeutic range.
