EGAN’S FUNDAMENTALS OF RESPIRATORY
CARE EXAMINATION TEST 2026
◉ Your patient has an elevated creatine kinase level. What two
organs are most likely diseased? Answer: heart and skeletal muscle
◉ What is the upper limit of normal for the fasting blood glucose
level? Answer: 140 mg/dl
◉ Which of the following symptoms is least often associated with
hypoglycemia? Answer: shortness of breath
◉ Valvular defects in the heart can be detected with a 12-lead ECG.
Answer: false
◉ What term is used to define the ability of certain cardiac cells to
depolarize without stimulation? Answer: automaticity
◉ What structure normally paces the healthy heart? Answer:
sinoatrial (SA) node
◉ At what part of the cardiac conduction system does the electrical
impulse travel most rapidly? Answer: Purkinje fibers
,◉ What is the normal maximum length of the P wave? Answer: 3
mm
◉ What is the normal period of time for the PR interval? Answer:
not longer than 0.20 second

atrioventricular block
◉ What parameter is measured on the vertical axis of the ECG
paper? Answer: voltage
◉ The QRS of an ECG falls on a dark vertical line of the ECG paper.
Subsequent QRS complexes fall on every other dark line (10 mm
apart). What is the ventricular rate? Answer: 150/min
◉ What is suggested by inverted T waves on the ECG? Answer:
myocardial ischemia

True or false Answer: false
◉ What is a possible serious complication associated with atrial
fibrillation? Answer: atrial thrombi
◉ Sources for the electrical impulse that triggers cardiac contraction
that lie outside the sinoatrial node are referred to as ectopic foci.
Answer: true
◉ Under ideal conditions, electrochemical oxygen (O2) analyzers
have approximately what degree of accuracy? Answer: 2%
◉ You are asked to provide continuous monitoring of the FIO2
provided by a humidified O2 delivery system using a galvanic cell
analyzer. Where would you install the analyzer's sensor? Answer:
proximal to the heated humidifier
◉ After obtaining an arterial blood sample through percutaneous
puncture using a syringe that does not have a capping safety device,
what should you do? Answer: "Scoop" the needle cap up with one
hand, then plug the syringe.
◉ When performing a percutaneous needle puncture of the radial
artery, you get only a small spurt of blood. Which of the following is
, the best action at this time? Answer: Slowly withdraw the needle
until a pulsatile flow fills the syringe.
◉ A PaO2 below what value would be considered severe hypoxemia?
Answer: 40 mm Hg
◉ What is a normal level for CaO2? Answer: 18 to 20 ml/100 ml
◉ To assess gas exchange at the tissues, you would obtain a blood
sample from which of the following? Answer: pulmonary artery
(balloon-inflated)
◉ What is the best site for capillary puncture in an infant? Answer:
lateral aspect of the heel's plantar surface
◉ What media are used to calibrate a blood gas analyzer's gas
electrodes? Answer: precision mixtures of O2 and CO2
◉ Statistically derived limits for internal quality control of blood gas
samples are usually set at what appropriate level? Answer: 2
standard deviations from the mean
◉ Oximetry is the measurement of blood hemoglobin saturations
using what technique? Answer: spectrophotometry
