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. A client is unconscious with a breathing pattern characterized by alternating periods of hyperventilation and apnea. The nurse should document that the client has which of the following respiratory alterations?

• A. Kussmaul respirations
• B. Apneustic respirations
• C. Cheyne-Stokes respirations
• D. Stridor

Correct answer: C

Rationale: Cheyne-Stokes respirations are characterized by periods of deep, rapid breathing followed by periods of apnea. This pattern is often seen in clients with neurological or cardiac conditions. Kussmaul respirations are deep and rapid breaths often associated with metabolic acidosis. Apneustic respirations are characterized by prolonged inhalations with shortened exhalations and can indicate damage to the pons. Stridor is a high-pitched, noisy respiratory sound usually associated with upper airway obstruction. Therefore, in this scenario, the client's alternating pattern of hyperventilation and apnea aligns with Cheyne-Stokes respirations.

3. A nurse is caring for four hospitalized clients. Which of the following clients should the nurse identify as being at risk for fluid volume deficit?

• A. The client who has been NPO since midnight for endoscopy
• B. The client who has left-sided heart failure and has a brain natriuretic peptide (BNP) level of 600 pg/mL
• C. The client who has end-stage renal failure and is scheduled for dialysis today
• D. The client who has gastroenteritis and is febrile

Correct answer: D

Rationale: Gastroenteritis can lead to fluid loss through vomiting and diarrhea, especially when accompanied by fever. Fever can increase insensible water loss through sweating as well. Both vomiting and diarrhea can significantly contribute to fluid volume deficit, making the client with gastroenteritis and fever at higher risk compared to the other clients described in the options.

4. A client has a pulmonary embolism & is started on oxygen. The student nurse asks why the client's oxygen saturation has not significantly improved. What response by the nurse is best?

• A. Breathing so rapidly interferes with oxygenation.
• B. Maybe the client has respiratory distress syndrome.
• C. The blood clot interferes with perfusion in the lungs.
• D. The client needs immediate intubation & mechanical ventilation.

Correct answer: C

Rationale: A large blood clot in the lungs will significantly impair gas exchange & oxygenation. Unless the clot is dissolved, this process will continue unabated.

5. When reviewing the provider's orders, a nurse recognizes that clarification is needed for which of the following medications in a client experiencing an exacerbation of asthma?

• A. Propranolol
• B. Theophylline
• C. Montelukast
• D. Prednisone

Correct answer: A

Rationale: The correct answer is Propranolol. Propranolol is a beta-blocker that can potentially exacerbate asthma symptoms due to its mechanism of action. It can cause bronchoconstriction, which is harmful for a client experiencing an asthma exacerbation. Theophylline, Montelukast, and Prednisone are commonly used in the treatment of asthma exacerbations and would not typically require clarification in this context.
