Questions And Answers
2025-2026 GRADED A+
acidemia - ANS-lower than normal blood pH; increased hydrogen ions
Acidosis - ANS-pH < 7.35; process that leads to an increase of hydrogen ion
concentration in the blood
adventitious breath sounds - ANS-Abnormal breath sounds such as wheezing,
stridor, rhonchi, and crackles.
apnea - ANS-absence of breathing
alkalemia - ANS-blood pH > 7.45; decreased hydrogen ion concentration
Alkalosis - ANS-process that leads to decreased hydrogen ions concentration
Apneustic breathing - ANS-Abnormal respiration marked by prolonged inspiration
interrupted by occasional expiration
atelectasis - ANS-collapse of alveoli
bradypnea - ANS-Slow breathing (less than 8/min)
bronchiectasis - ANS-dilation of the bronchi
bronchospasm - ANS-constriction of bronchi caused by spasm of the
peribronchial smooth muscle
, central sleep apnea - ANS-sleep disorder with periods of interrupted breathing
due to a disruption in signals sent from the brain that regulate breathing
Cheyne-Stokes respiration - ANS-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) - ANS-a measure of distensibility of the lungs; the amount of
change in volume per change in pressure across the lung.
cyanosis - ANS-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 - ANS-shortness of breath
epistaxis - ANS-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 - ANS-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 - ANS-excessive carbon dioxide (Paco2) in the bloodstream ,
typically caused by inadequate respiration.
hyperoxemia - ANS-increased oxygen (Pao2) in the blood
Hyperventilation - ANS-overventilation of the alveoli in relation to the amount of
carbon dioxide produced by the body.
hypocapnia - ANS-condition of deficient carbon dioxide (Paco2)in the blood
