Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

2. A nurse is planning care for a client who has a closed head injury and has an intraventricular catheter. Which of the following interventions should the nurse include to reduce the risk for infection?

• A. Keep the head of the bed elevated to 30 degrees.
• B. Administer IV antibiotics prophylactically.
• C. Change the catheter insertion site every 24 hours.
• D. Monitor the insertion site for redness.

Correct answer: D

Rationale: The correct answer is to monitor the insertion site for redness. This intervention helps detect signs of infection early in clients with intraventricular catheters. Keeping the head of the bed elevated to 30 degrees is important for managing intracranial pressure but does not directly reduce the risk of infection. Administering IV antibiotics prophylactically is not recommended as a routine practice due to the risk of antibiotic resistance and should only be done based on culture results. Changing the catheter insertion site every 24 hours is unnecessary and increases the risk of introducing new pathogens.

3. What is the first action for a healthcare provider when a patient experiences a fall?

• A. Assess the patient for injuries
• B. Call for help
• C. Document the fall
• D. Notify the healthcare provider

Correct answer: A

Rationale: The correct answer is to 'Assess the patient for injuries' when a patient experiences a fall. This is crucial to promptly identify any injuries and provide appropriate care. Calling for help may be necessary, but assessing the patient's condition takes precedence to ensure immediate attention to any injuries. Documenting the fall and notifying the healthcare provider would follow after the initial assessment and necessary actions have been taken.

4. A client is receiving heparin therapy. Which of the following laboratory results indicates the client is receiving an effective dose of heparin?

• A. INR 1.5
• B. aPTT 60 seconds
• C. Platelets 150,000/mm³
• D. Potassium 4.0 mEq/L

Correct answer: B

Rationale: An aPTT of 60 seconds indicates the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for a clot to form, and a therapeutic range for heparin therapy is usually 1.5 to 2 times the control value, which is around 60-80 seconds. An INR of 1.5 is not related to heparin therapy, as it is commonly used to monitor warfarin therapy. Platelet count and potassium levels are not direct indicators of the effectiveness of heparin therapy.

5. A nurse is caring for a client who is 36 hours postoperative following abdominal surgery. Which of the following findings should the nurse report to the provider?

• A. Heart rate of 92/min
• B. Serosanguineous wound drainage
• C. Yellow wound drainage
• D. Blood pressure of 118/76 mm Hg

Correct answer: C

Rationale: Yellow wound drainage can indicate infection, especially 36 hours postoperative, and should be reported to the provider promptly. Serosanguineous drainage is a normal finding in the early stages of wound healing, and a heart rate of 92/min and a blood pressure of 118/76 mm Hg are within normal ranges for a postoperative client. Therefore, the nurse should prioritize reporting the yellow wound drainage as it may require immediate intervention.
