NURO670 final Exam Questions With Correct
Answers

indications for PA catheter - answers✔✔Dx/management of shock states

assessment of volume status

oliguric ARF

titration of meds for cardiogenic shock

Frank-Starling Law - answers✔✔The greater the ventricle is stretched, the greater the force of
contraction to a point- beyond that, increased preload (overstretching) can decrease ejected volume

a wave - answers✔✔rise in pressure from atrial contraction

c wave - answers✔✔rise in pressure from ventricular contraction

x descent - answers✔✔relaxation of atria

v wave - answers✔✔filling of atria

y descent - answers✔✔filling of ventricles

overdampened - answers✔✔waveform less distinct

underdampened - answers✔✔waveform features exaggerated

when should values be obtained - answers✔✔at end expiration (lowest thoracic pressure)

when is the PAOP most accurate - answers✔✔when the catheter tip is in lung zone 3

factors affecting preload - answers✔✔venous return

venous tone

atrial kick

ventricular contractility

factors affecting afterload - answers✔✔primary pHTN

hypoxia

drugs

what is contractility - answers✔✔the force of the contraction
