Name ______
Department ______
E-mail address ______
Please highlight or bold your answers and e-mail to
1. Positive end expiratory pressure (PEEP) allows the body to:
a. increase respiratory rate.
b. increase heart rate.
c. keep airways open and prevent them from collapsing.
d. all of the above.
2. CPAP can deliver PEEP of various levels. Our protocol allows PEEP of:
a. 5 cm - 10 cm on adult patients.
b. 5 cm - 10 cm on all patients.
c. 5 cm - 7.5 cm on all pediatric patients.
d. all of the above.
3. The primary goal of CPAP is to:
a. increase the work of breathing.
b. decrease the work of breathing.
c. decrease PEEP to near zero levels.
d. prevent unnecessary intubations.
4. Which of the following patients would be a candidate for CPAP?
a. Awake, able to follow verbal commands, > 12 years of age, severe respiratory distress.
b. Unresponsive, SBP > 90 mm, respiratory rate > 25/minute.
c. COPD patient, cooperative, sPO2 of 91%, no respiratory distress.
d. Able to maintain open airway, accessory muscle use, suspected
pneumothorax.
5. CPAP causes an increase in intrathoracic pressure. This is beneficial to patients suffering from pulmonary edema associated with CHF because it:
a. decreases venous return to the heart thereby reducing preload.
b. decreases afterload thereby reducing required systolic pressure for
perfusion.
c. improves left ventricular function by both of the above.
d. all of the above.
e. none of the above.
6. COPD patients benefit from CPAP by:
a. decrease in work of breathing.
b. reinflate collapsed alveoli.
c. aid in removing mucus plugs.
d. all of the above.
e. none of the above.
7. CPAP eliminates the need for additional respiratory therapies or interventions
such as medications.
a. True.
b. False.
8. CPAP does not breathe for a patient the way a ventilator does or an EMT using a BVM does. Patients placed on CPAP must be responsive, able to follow commands and still breathing.
a. True.
b. False.
9. The pathophysiological changes that occur during an acute asthma attack result in obstruction of expiratory air flow. This is caused by:
a. bronchial inflammation, bronchoconstriction and excess mucus production.
b. alveolar collapse, bronchodilation and decrease in mucus production.
c. inflammation, bronchodilation and excess mucus production.
d. interstitial fluid accumulation and bronchoconstriction.
10. CPAP may benefit patients who:
a. have inhaled toxic gases.
b. have symptoms consistent with HAPE.
c. have incurred CO or organophosphate exposure.
d. all of the above.
e. none of the above.
11. The most common problem or side effect associated with CPAP is:
a. pneumothorax.
b. hypotension.
c. gastric distension.
d. anxiety.
12. CPAP should be removed from a patient when:
a. the patient’s condition deteriorates and they become unresponsive.
b. development of pneumothorax is suspected.
c. pulse oximetry (sPO2) reading do not increase above initial findings.
d. a and b.
e. a and c.
f. none of the above.
13. Coaching a patient during application and use of CPAP is of benefit because:
a. it helps reduce patient anxiety.
b. by reducing anxiety, it encourages the patient to tolerate CPAP and leave it in place.
c. by encouraging the patient to leave CPAP in place, it increases the chances of the patient benefiting from CPAP.
d. all of the above.
14. For which of the following patients is CPAP contraindicated?
a. Alert, cooperative, able to follow commands.
b. Alert, cooperative, SBP > 90, sPO2 of 91%.
c. Alert, cooperative, poor respiratory drive but breathing.
d. Unresponsive, RR> 25, sPO2 of 90%.
15. The most common cause of hypoxia is a compromised airway with respiratory insufficiency. This can be due to airway obstruction, decreased respiratory effort or a host of other complications. The EMT conducting an assessment on a patient must be aware of clinical indicators that suggests a patient has respiratory distress and may become hypoxic. Some of those indicators include:
a. tachypnea, altered mental status, tachycardia.
b. bradypnea, altered mental status, bradycardia.
c. cyanosis, noisy respirations, mottling, altered mental status.
d. all of the above.
