breathing pattern is best described by which of the following?
A. Hyperventilation
B. Dyspnea
C. Hypoventilation
D. Tachypnea - Answers-D. Tachypnea
The RT is assessing a patient with severe emphysema and observes pedal edema and jugular
venous distention. The therapist should note in the patient's chart that these signs are most
likely the result of:
A. Systemic hypertension
B. Hypercapnia
C. Pulmonary infection
D. Right ventricular hypertrophy - Answers-D. Right ventricular hypertrophy

ETT reads 1.5%. The RT should suspect which of the following?
,A. The tube is in the trachea
B. The tube is in the right mainstem bronchus and should be withdrawn 4 cm
C. The tube is in the esophagus
D. The tube is at the level of the carina and should be withdrawn 2 cm - Answers-C. The tube
is in the esophagus

auto-peep in a patient?
A. flow/time
B. flow/volume
C. pressure/time
D. volume/pressure - Answers-A. flow/time
The following data are obtained for a patient who is receiving VC, A/C ventilation:
Peak pressure: 30 cm H2O
Plateau pressure: 20 cm H2O
Set Vt: 800 mL
Exhaled Vt: 700 mL
PEEP: 10 cm H2O

A patient is receiving O2 from an E cylinder at 4 L/min through a nasal cannula. The cylinder
pressure is 1900 psig. How long will the cylinder run until it is empty?
A. 47 min
B. 1.7 h
