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 with asthma is being taught about peak flow meter use. Which statement by the client indicates understanding of the teaching?

• A. I will use my peak flow meter every morning.
• B. I will use my peak flow meter when I feel short of breath.
• C. I will use my peak flow meter before using my inhaler.
• D. I will use my peak flow meter after using my inhaler.

Correct answer: A

Rationale: The correct answer is A. Using the peak flow meter every morning is crucial for monitoring asthma control and making timely treatment adjustments. While using the meter when feeling short of breath or before using an inhaler can also be beneficial, the daily morning routine helps in consistent management of asthma symptoms.

3. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

4. During an assessment in the emergency department, an older adult client with community-acquired pneumonia is found to be confused. Which of the following findings should the nurse expect?

• A. Unequal pupils
• B. Hypertension
• C. Tympany upon chest percussion
• D. Confusion

Correct answer: D

Rationale: Confusion is a common finding in older adult clients with pneumonia, often indicating hypoxia. Hypertension, unequal pupils, and tympany upon chest percussion are not typically associated with community-acquired pneumonia in older adults.

5. A client just had a flexible bronchoscopy. Which of the following nursing actions is appropriate?

• A. Withhold food and liquids until the client's gag reflex returns.
• B. Irrigate the client's throat every 4 hours.
• C. Have the client refrain from talking for 24 hours.
• D. Suction the client's oropharynx frequently.

Correct answer: A

Rationale: After a flexible bronchoscopy, it is crucial to withhold food and liquids until the client's gag reflex returns to prevent aspiration. Irrigating the client's throat every 4 hours, having the client refrain from talking for 24 hours, and frequent suctioning of the oropharynx are not indicated post-bronchoscopy and may even pose risks to the client's recovery.
