Deck 43: Respiratory Care Practice Review

Question 1

Which oxygen delivery method is most helpful for patients with obstructive sleep apnea?

A) Liquid oxygen
B) Partial rebreathing mask
C) CPAP
D) Heliox

Answer 1

C
Continuous positive airway pressure (CPAP)is oxygen delivered with pressure above atmospheric pressure.CPAP may be used to improve oxygenation for patients in whom the usual means of oxygen delivery are not effective and patients with obstructive sleep apnea.

Question 2

Which device is most commonly used with high-flow oxygen systems?

A) Partial rebreathing mask
B) Nonrebreathing mask
C) Venturi mask
D) Transtracheal oxygen catheter

Answer 2

C
The Venturi mask is a common method of delivering high-flow oxygen concentrations from 24% to 50%.This mask operates via the Venturi principle,which provides for a mixing of 100% oxygen and entrained ambient air.

Question 3

Which term refers to breathing through a ventilator circuit without assistance?

A) Intermittent mandatory ventilation
B) Spontaneous breathing
C) Controlled mechanical ventilation
D) Assist control of ventilation

Answer 3

B
Spontaneous breathing is breathing through the ventilator circuit without assistance.The other terms refer to modes of assisted ventilation.

Question 4

Which of the following is used to ensure mandatory minute ventilation?

A) Pressure support ventilation
B) Triggers
C) Incentive spirometry
D) None of the above

Question 5

Which location is included in the scope of a respiratory therapist?

A) Hospitals
B) Long-term care
C) Patients' homes
D) All of the above

Question 6

When may humidification therapy be indicated?

A) In the presence of thick, tenacious secretions
B) When an endotracheal tube is in place
C) When a tracheostomy tube is in place
D) All of the above

Question 7

Which of the following is most cost effective and strictly used to deliver medication?

A) SVN
B) MDI
C) COPD
D) FEV

Question 8

Which is a serious concern when portable oxygen is prescribed?

A) Cooking with a gas stove
B) Smoking or having others smoke nearby
C) The patient's understanding about his or her prescribed level of oxygen
D) All of the above

Question 9

Which aspect of a patient is especially important to evaluate when a nasal cannula is used?

A) Skin integrity
B) Blood pressure
C) Thirst and appetite
D) Sleeping patterns

Question 10

Which device has become more popular over the past 20 years for supporting patients with Duchenne muscular dystrophy and cystic fibrosis?

Which device is often used to deliver low-flow oxygen?

A) Oximeter
B) Nasal cannula
C) Arterial line
D) Venturi mask

Question 12

Which term describes the speed at which a ventilator breath is delivered?

A) Frequency
B) Flow rate
C) Spontaneous breath
D) Trigger

Question 13

Compared with standard ventilator treatment without waking patients for therapy,which of the following can be achieved with early physical therapy in patients on mechanical ventilation?

A) Fewer ventilator days
B) Fewer days of delirium
C) Better function outcomes at discharge
D) All of the above

Question 14

Which is an appropriate purpose of oxygen therapy?

A) Treat and prevent hypoxemia.
B) Treat and prevent excessive work of breathing.
C) Treat and prevent excessive myocardial work.
D) All of the above

Question 15

Which alarm sounds most commonly when a ventilated patient is receiving physical therapy?

A) High-pressure alarm
B) Apnea alarm
C) FiO₂ alarm
