FisDap Airway + Anatomy Questions with 100% Correct Solutions | Rated A+

What is the term for abnormal breath sounds that result from an obstructed airway? a. crackles b. wheezing c. snoring d. stridor - 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 - 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 - 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 - 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 - 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 - 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 the patient begins to tire, the RR and quality will begin to decrease, which worsens the problem What is the amount of air that normally reaches the alveoli in an adult? a. 350 ml b. 150 L c. 500 ml d. 750 L - a. 350 ml The average adult ventilation is 500 mL, but there ia an area of dead space that traps 150 ml of air so only 350 mL effectively reaches the alveoli for oxygen and carbon dioxide exchange. A 56 year old female has a complete airway obstruction from a piece of food. She becomes unconscious while you assess her. What should you do? a. begin chets compressions b. perform a finger sweep c. attempt to ventilate her d. deliver up to 5 abdominal thrusts - a. begin chets compressions
