CAPA certification questions with
complete solutions graded A+
acidemia - correct answer ✔✔lower than normal blood pH; increased hydrogen ions
Acidosis - correct answer ✔✔pH < 7.35; process that leads to an increase of hydrogen ion concentration
in the blood
adventitious breath sounds - correct answer ✔✔Abnormal breath sounds such as wheezing, stridor,
rhonchi, and crackles.
apnea - correct answer ✔✔absence of breathing
alkalemia - correct answer ✔✔blood pH > 7.45; decreased hydrogen ion concentration
Alkalosis - correct answer ✔✔process that leads to decreased hydrogen ions concentration
Apneustic breathing - correct answer ✔✔Abnormal respiration marked by prolonged inspiration
interrupted by occasional expiration
atelectasis - correct answer ✔✔collapse of alveoli
bradypnea - correct answer ✔✔Slow breathing (less than 8/min)
bronchiectasis - correct answer ✔✔dilation of the bronchi
bronchospasm - correct answer ✔✔constriction of bronchi caused by spasm of the peribronchial smooth
muscle
, central sleep apnea - correct answer ✔✔sleep disorder with periods of interrupted breathing due to a
disruption in signals sent from the brain that regulate breathing
Cheyne-Stokes respiration - correct answer ✔✔a pattern of alternating periods of hypopnea or apnea,
followed by hyperpnea; associated with brain damage, heart or kidney failure, or drug overdose
compliance (lung) - correct answer ✔✔a measure of distensibility of the lungs; the amount of change in
volume per change in pressure across the lung.
cyanosis - correct answer ✔✔a bluish discoloration of the skin resulting from poor circulation or
inadequate oxygenation of the blood; more than 5g of hemogloblin/ deciliter of arterial blood is
deoxygenated.
Dyspnea - correct answer ✔✔shortness of breath
epistaxis - correct answer ✔✔nosebleed; usually in the Kiesselbach plexus or the Little's area; can occur
in PACU d/t trauma to the nasal veins from nasotracheal tubes or to nasal airways during anesthesia.
Treating epistaxis - correct answer ✔✔prompt action to prevent aspiration; position patient head up and
flexed forward toward the chest; cold compresses to the bridge of the nose and neck. If bleeding is
profuse, then suction oral cavity and notify attending. Packing or cautery with silver nitrate or electric
current may be necessary.
hypercapnia - correct answer ✔✔excessive carbon dioxide (Paco2) in the bloodstream , typically caused
by inadequate respiration.
hyperoxemia - correct answer ✔✔increased oxygen (Pao2) in the blood
Hyperventilation - correct answer ✔✔overventilation of the alveoli in relation to the amount of carbon
dioxide produced by the body.
hypocapnia - correct answer ✔✔condition of deficient carbon dioxide (Paco2)in the blood
