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
death after vascular surgery?

CAD - ✔ ✔ Because atherosclerosis does not occur in one vessel,
patients requiring vascular surgery are likely also to have
___________________________.

dissecting aortic aneurysm - ✔ ✔ The first diagnostic test should be a

__________.

mitral - ✔ ✔ ___________ valve stenosis causes LA enlargement and
wide, notched P Waves

block type I, and third-degree AV heart block at the level of the AV node
would occur in _______________ occlusion

ADH - ✔ ✔ Phenytoin inhibits _______ secretion

enlargement on an EKG in lead II?

abnormal/normal.

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

pleurodesis - ✔ ✔ injection of a sclerosing agent into the pleural space
and is used for pleural effusion

LAD - ✔ ✔ The__________ coronary artery supplies the bundle of His and
bundle branches
