Alternative Methods of Ventilatory Support

NCLEX-Style Questions

1. What is the primary goal of alternative methods of ventilatory support?
o A) To eliminate the need for intubation
o B) To improve oxygenation and ventilation
o C) To increase patient comfort
o D) To reduce nursing workload
o Correct Answer: B
o Rationale: The main goal of alternative ventilatory methods is to enhance
oxygenation and ventilation while minimizing complications associated with
invasive methods.
2. Which of the following is a benefit of Continuous Positive Airway Pressure (CPAP)?
o A) Decreases respiratory effort
o B) Prevents atelectasis
o C) Requires sedation
o D) Is invasive
o Correct Answer: B
o Rationale: CPAP is non-invasive and helps to prevent atelectasis by maintaining
positive pressure in the airways.
3. In what situation is Bi-Level Positive Airway Pressure (BiPAP) most commonly
used?
o A) Acute respiratory distress syndrome (ARDS)
o B) Chronic obstructive pulmonary disease (COPD) exacerbations
o C) Cardiac arrest
o D) Sleep apnea
o Correct Answer: B
o Rationale: BiPAP is particularly effective for patients with COPD exacerbations,
as it provides different levels of pressure for inhalation and exhalation.
4. Which parameter should be monitored closely when using Non-Invasive Ventilation
(NIV)?
o A) Temperature
o B) Blood pressure
o C) Respiratory rate
o D) Level of consciousness
o Correct Answer: C
o Rationale: Respiratory rate is crucial to assess the effectiveness of NIV and the
patient's respiratory effort.
5. What is the primary purpose of high-flow nasal cannula (HFNC) therapy?
o A) To provide mechanical ventilation
o B) To deliver heated and humidified oxygen
o C) To sedate the patient
o D) To reduce anxiety
o Correct Answer: B
o Rationale: HFNC delivers high concentrations of heated and humidified oxygen,
which can improve patient comfort and oxygenation.

, 6. A nurse is assessing a patient on CPAP. Which finding would indicate that the
treatment is effective?
o A) Increased heart rate
o B) Decreased respiratory effort
o C) Increased work of breathing
o D) Cyanosis of lips
o Correct Answer: B
o Rationale: Decreased respiratory effort indicates that the patient is receiving
adequate support from CPAP.
7. Which of the following patients would most likely benefit from using a helmet for
non-invasive ventilation?
o A) A patient with a tracheostomy
o B) A patient with anxiety
o C) A patient with facial trauma
o D) A patient with a history of clostridium difficile infection
o Correct Answer: C
o Rationale: A helmet can provide non-invasive ventilation without putting
pressure on facial structures, making it ideal for patients with facial trauma.
8. What should the nurse include in the care plan for a patient using BiPAP?
o A) Frequent oral care
o B) Encourage speaking
o C) Restrict fluid intake
o D) Position the patient flat
o Correct Answer: A
o Rationale: Frequent oral care is essential to prevent dryness and discomfort
associated with mask ventilation.
9. Which is a contraindication for the use of Non-Invasive Ventilation (NIV)?
o A) Cardiogenic pulmonary edema
o B) Respiratory muscle fatigue
o C) Severe hypoxemia
o D) Unconsciousness
o Correct Answer: D
o Rationale: Patients who are unconscious may not be able to cooperate with NIV
and require intubation instead.
10. A patient receiving HFNC is noted to have increased work of breathing. What is the
nurse’s priority action?
o A) Increase the flow rate
o B) Assess for underlying causes
o C) Change to CPAP
o D) Administer bronchodilators
o Correct Answer: B
o Rationale: Assessing for underlying causes of increased work of breathing is
essential before making any changes to the therapy.
11. Which nursing intervention is essential when using mechanical ventilation in
critically ill patients?
o A) Frequent sedation
