OCEMT Final Exam questions with correct answersWhat are the respiratory rates when we should consider a BVM? How
do we determine adequate respirations? Correct Answer-Slower than
Normal Rates or Shallow depth of breath Pg. 400
Adults 12-20 breaths/min
Children 15-30 breaths/min
Infant 25-50 breaths/min
- The BVM should be used when you need to deliver high
concentrations of oxygen to patients who are not ventilating adequately,
in respiratory arrest, cardiopulmonary arrest and respiratory failure. Pg.
428
- The volume of air(oxygen) delivered to the patient is based on chest
rise and fall Pg. 429
Wheezing Correct Answer-Lower airway obstruction high pitch sound,
most prominent on exhalation
Ronchi Correct Answer-Congested breath sounds may suggest the
presence of mucus in the lungs. Expect to hear low pitched, noisy
sounds that are most prominent on expiration. The patient often reports a
productive cough associated. Snoring due to upper airway obstructions
(Snoring) (Ronchi is lower airway)
,Crackles(Rales) Correct Answer-Fluid build in lungs air passes through
fluid from the alveoli to the capillaries (wet lung sounds). Usually on
both inspiration and expiration.(Lower Airway)
Stridor Correct Answer-Seal bark cough. Often heard before listening
with a stethoscope and may indicate the patient has an airway
obstruction in the neck and upper part of the chest. Expect to hear a
brassy, crowing sound that is most prominent on inspiration.(More seen
in Pediatrics)(Upper Airway)
Corrective action if we no longer see visible chest rise while performing
PP ventilation. Pg. 431. Correct Answer--Check mask seal
-Reposition the head or use airway adjunct
-Check for airway obstruction; if not obstructions present try alternative
ventilation method such as mouth-to-mask technique
Oxygen flow rates for: Pg. 423 Correct Answer--Nasal cannula
(1-6L/min) 24%-44% O2
-Non-rebreather mask w/ reservoir (10-15L/min) 95% O2
-BVM ( 15L/min) Nearly 100% O2
-Mouth-to-mask device (15L/min) Nearly 55% O2
-Nebulized breathing treatment (6-8L/min)Pg. 475
Airway obstruction knowledge:
1) Witness patient collapse.......what should your first objective be?
, 2) What to ask and how to approach a patient who is possibly choking?
3) When do we simply encourage them to cough? Correct Answer-1)
check for ABC's; see if you can fix airway right away
2) -Are you choking?
-If you hear noise or are able to communicate just encourage to cough it
out if you see signs of blue or hand in choking position and unable to
communicate start with abdominal thrust... back slaps in infants
3)As long as the patient can breathe, cough forcefully, or talk Pg.
440/542
How to treat a patient with a STOMA that is not with adequate
respirations? Correct Answer--If the patient has a Tracheostomy Tube,
ventilate through the tube with a BVM(The standard 15/22-MM adapter
on the BVM will fit onto the tube in the tracheal stoma) and 100%
oxygen attached directly to BVM.
-If there is no tube in place, use an infant or child mask with BVM to
make a seal over the stoma. Seal the patient's mouth and nose with one
hand to prevent a leak of air during ventilation. Release mouth and nose
for exhalation.
