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. 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.

3. A client presents with shortness of breath, pain in the lung area, and a recent history of starting birth control pills and smoking. Vital signs include a heart rate of 110/min, respiratory rate of 40/min, and blood pressure of 140/80 mm Hg. Arterial blood gases reveal pH 7.50, PaCO2 29 mm Hg, PaO2 60 mm Hg, HCO3 20 mEq/L, and SaO2 86%. What is the priority nursing intervention?

• A. Prepare for mechanical ventilation.
• B. Administer oxygen via face mask.
• C. Prepare to administer a sedative.
• D. Assess for indications of pulmonary embolism.

Correct answer: B

Rationale: In a client with a high respiratory rate, low PaO2, and low SaO2, the priority intervention is to improve oxygenation. Administering oxygen via a face mask will help increase the oxygen supply to the client's lungs and tissues, addressing the hypoxemia. While mechanical ventilation may be necessary in severe cases, administering oxygen is the initial and most appropriate intervention to address the client's respiratory distress. Sedatives should not be given without ensuring adequate oxygenation. Assessing for pulmonary embolism is important but not the priority at this moment when the client is experiencing respiratory distress and hypoxemia.

4. A client with chronic obstructive pulmonary disease (COPD) is being taught by a healthcare provider. Which statement by the client indicates a need for further teaching?

• A. I will avoid smoking to prevent further damage to my lungs.
• B. I will eat smaller, more frequent meals to avoid feeling bloated.
• C. I will exercise every day to improve my strength and endurance.
• D. I will drink plenty of fluids to help thin my mucus.

Correct answer: C

Rationale: The correct answer is C. While exercise is important for clients with COPD, daily exercise may be too strenuous. Clients should be encouraged to exercise regularly but should be advised to avoid overexertion. Statements A, B, and D demonstrate appropriate understanding and management of COPD symptoms.

5. After a thoracentesis, a healthcare provider assesses a client. Which assessment finding warrants immediate action?

• A. The client rates pain as 5/10 at the site of the procedure.
• B. A small amount of drainage is noted from the site.
• C. Pulse oximetry reads 93% on 2 liters of oxygen.
• D. The trachea is deviated toward the opposite side of the neck.

Correct answer: D

Rationale: A deviated trachea indicates a tension pneumothorax, a life-threatening emergency. This condition can rapidly lead to respiratory failure and requires immediate intervention. The other assessment findings, such as pain level, mild drainage, and slightly decreased oxygen saturation, are within an expected range after a thoracentesis and do not indicate an immediate threat to the client's life.
