Nursing Elites

1. A client who is receiving mechanical ventilation and has an ideal weight of 60 kg should have the tidal volume set at which of the following?

• A. 300 mL
• B. 480 mL
• C. 800 mL
• D. 950 mL

Correct answer: B

Rationale: Tidal volume is the amount of air delivered with each breath during mechanical ventilation. A common formula used to calculate tidal volume is 6-8 mL/kg of ideal body weight. For a client with an ideal weight of 60 kg, the expected tidal volume would be 60 kg x 6-8 mL/kg = 360-480 mL. Therefore, the most appropriate choice is 480 mL (Option B), which falls within the expected range based on the client's weight.

2. What instruction should be included when teaching a client with asthma about using a metered-dose inhaler (MDI)?

• A. Shake the inhaler well before use.
• B. Inhale rapidly while administering the medication.
• C. Administer the medication while lying down.
• D. Hold the inhaler 2 inches away from the mouth while inhaling.

Correct answer: A

Rationale: Shaking the inhaler well before use ensures that the medication is properly mixed, allowing for an accurate dose with each administration. Inhaling slowly and deeply, not rapidly, helps the medication reach the lungs effectively. The medication should be administered while sitting or standing to facilitate proper lung expansion and airflow. Holding the inhaler 2 inches away from the mouth can lead to medication loss; it should be placed directly in the mouth or used with a spacer to optimize delivery to the airways.

3. A client is scheduled to have a tracheostomy placed in an hour. What action by the nurse is the priority?

• A. Administer prescribed anxiolytic medication.
• B. Ensure informed consent is on the chart.
• C. Reinforce any teaching done previously.
• D. Start the preoperative antibiotic infusion.

Correct answer: B

Rationale: The priority action for the nurse is to ensure that informed consent is on the chart. Before any surgical procedure, it is essential to have the client's informed consent documented. While administering anxiolytics, starting antibiotic infusion, and reinforcing teaching may also be necessary, obtaining informed consent takes precedence to ensure the client's understanding and agreement to proceed with the tracheostomy.

4. A client develops a pulmonary embolism. Which of the following interventions should the nurse implement first?

• A. Give morphine IV.
• B. Administer oxygen therapy.
• C. Start an IV infusion of lactated Ringer's.
• D. Initiate cardiac monitoring.

Correct answer: B

Rationale: Administering oxygen therapy is the priority intervention for a client with a pulmonary embolism. Oxygen helps improve oxygenation levels and decrease the workload on the heart. It is crucial to ensure adequate oxygenation before other interventions are initiated. Morphine IV, starting an IV infusion of lactated Ringer's, and initiating cardiac monitoring are important interventions but come after ensuring adequate oxygenation.

5. When caring for a client with acute renal failure, which laboratory value is most important to monitor?

• A. Serum sodium
• B. Serum potassium
• C. Serum calcium
• D. Serum chloride

Correct answer: B

Rationale: In acute renal failure, monitoring serum potassium is crucial because impaired kidney function can lead to hyperkalemia, which can result in life-threatening cardiac dysrhythmias. Elevated potassium levels need close monitoring and prompt interventions to prevent serious complications.
