Barron/Elsevier CCRN 326 practice
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
CXR film for probable diagnosis. The film would reveal a widening
mediastinum. An additional, more indicative finding would be calcified
aortic knob with extension of the aortic wall.
left - ✔ ✔ A wide, notched P wave is an indication of ________ atrial
enlargement.
P mitrale - ✔ ✔ Left atrial enlargement causes the P wave to be wide
(greater than 0.1 second) and notched. This sometimes is referred to as ___
__________.
mitral - ✔ ✔ ___________ valve stenosis causes LA enlargement and
wide, notched P Waves
RCA (as seen in inferior wall MIs) - ✔ ✔ SA blocks, second-degree AV
block type I, and third-degree AV heart block at the level of the AV node
would occur in _______________ occlusion
ADH - ✔ ✔ Phenytoin inhibits _______ secretion
Right - ✔ ✔ Most episodes of aspiration result in (right/left) lung
infiltrates.
urine creatinine clearance - ✔ ✔ Best indicator of GFR
, Auto-PEEP - ✔ ✔ In a vented patient with status asthmaticus, check
for _______________
Air trapping - ✔ ✔ An increase in auto-PEEP is a sign of
_________________.
obstructive pulmonary disease - ✔ ✔ A patient with a flattened
diaphragm on a Chest X-ray and decreased expiratory flow rate most
likely has what type of disease?
II and V1 - ✔ ✔ ____ and ______ are the two best P wave leads.
wide, notched P waves - ✔ ✔ What is a manifestation of left atrial
enlargement on an EKG in lead II?
normal - ✔ ✔ Diphasic P waves in lead V1 on 12-lead EKG are
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
anterior (LAD affected) - ✔ ✔ _____________ MIs may cause blocks of
the bundle of His or bundle branches
Right Coronary Artery (RCA)... LCA in 10% of ppl - ✔ ✔ Type I AV block,
also called Wenckebach, is a block at the AV node, and the AV node is
supplied by the ___________________ (in 90% of people)
sinus - ✔ ✔ the ____________ node is supplied by the RCA in 55% of ppl
and LCA in 45%
