CORRECT WELL DETAILED
What is the term for abnormal breath sounds that result from an obstructed airway?
a. crackles
b. wheezing
c. snoring
d. stridor - ANSWER d. stridor is an upper airway obstruction caused by tissue swelling
around the trachea, layrnx, or epiglotitis. Stridor is often present with an airway obstruction,
epiglottitis, or croup
What is the term for high-pitched whistling sounds heard during expiration?
a. friction rub
b. stridor
c. snoring
d. wheezing - ANSWER d. wheezing suggests lower airway obstrictions or
constrictions. Exhalation is a passive process and the wheezing noise is air pasively leaving
constriced bronchioles
What are the structures that branch off the trachea into the lower airway?
a. arterioles
b. bronchi
c. alveoli
d. cricoid - ANSWER b. bronchi
The trachea bifurcates (splits) at the carina into left and right bronchus. The bronchi get
smaller and smaller until it reaches the terminal bronchioles where the alveoli are located

, An 18 year old male is cyanotic and complains of sharp chest pain and difficulty breathing
after lifting weights. Vital signs are BP 110/66, P 88, and R 22. What is the most likely cause?
a. spontaneous pneumothorax
b. pulmonary embolism
c. tension pneumothorax
d. acute myocardial infarction - ANSWER b. pulmonary embolism
Performing strenuous activities can cause a collapsed lung (spontaneous pneumothorax). He
has sable vital signs so you should suspect a spontaneous pneumothorax. If he was
hypotensive, you should suspect spontaneous pneumothorax had developed into a tension
pneumothorax.
An alert 32 year old female complains of difficultly breathing. She speaks in 2-3 word
sentences and has an oxygen saturation of 92%. What should you do?
a. assist ventillations with a BVM
b. obtain VS
c. assist her with her MDI
d. apply high flow O2 - ANSWER d. apply high flow O2
She is alert and her respirations are still efective without the need for assiting ventilations.
SHe only complains of shortness of breath so applying high flow O2 should be the first
treatment
The use of accessory muscles and nasal flaring are signs of what type of breathing?
a. labored
b. normal
c. obstructed
d. shallow - ANSWER a. labored
The sue of accessory muscles is a sign of respiratory distress or failure. Nasal flaring is the
body's response in effor to increase the size of the airway and attempt to draw in more air
with each breath. Expect to initially see an increased RR and HR with labored breathing. As
