test questions
less - ✔ ✔ There is (more/less) risk of burning of the skin with
biphasic waveform defibrillation than with monophasic.
5 - ✔ ✔ Central cyanosis is cyanosis in central areas such as mucous
membranes and occurs when ____ g of hemoglobin is desaturated
bronchophony - ✔ ✔ when a spoken word is heard clearly, distinctly,
and loudly over an area of pneumonia during auscultation
volutrauma - ✔ ✔ shearing of the alveoli caused by overly large tidal
volumes
barotrauma - ✔ ✔ pneumothorax associated with mechanical
ventilation
opening snap - ✔ ✔ sound occurring in early diastole caused by a rapid
opening of a stenotic mitral valve
dysrhythmias
(trauma -> inflammation -> irritability) - ✔ ✔ most common
complication of myocardial contusion
pulmonic - ✔ ✔ On a pulmonary artery waveform, the dicrotic notch
represents closure of which valve?
diuretics and beta blockers - ✔ ✔ first-line therapy for chronic
management of hypertension
external respiration - ✔ ✔ the process of the movement of oxygen
across the alveolar-capillary membrane
,internal respiration - ✔ ✔ the use of oxygen by the mitochondria to
produce ATP
necrosis - ✔ ✔ adding too much air to a ETT cuff can cause
overinflation and tracheal ______________.
myocardial infarction (MI) - ✔ ✔ What is the most common cause of

patients requiring vascular surgery are likely also to have

enlargement on an EKG in lead II?

myoglobin - ✔ ✔ _________ is the earliest cardiac biomarker for a MI
(elevated within 3hrs s/p MI) and is nonspecific.
