NU122 Exam 3 Questions With Correct
Answers
Which term describes the ability of the heart to initiate an electrical impulse? -
answer✔Automaticity is the ability of specialized electrical cells of the cardiac conduction
system to initiate an electrical impulse
Contractility - answer✔ability of the specialized electrical cells of the cardiac conduction system
to contract in response to an electrical impulse.
conductivity - answer✔ability of the specialized electrical cells of the cardiac conduction system
to transmit an electrical impulse from one cell to another.
Excitability - answer✔ability to respond to stimuli
What drug will be used to dilate the coronary arteries? - answer✔adenosine (Adenocard),
dipyridamole (Persantine), or dobutamine (Dobutrex)
Central Venous Pressure over 6mmHg - answer✔hypervolemia or right sided heart failure
(increased ventricular preload)
Geriatric normal considerations - answer✔With age, the heart rate will decrease, and heart
block can occur with changes in the conduction system. Auscultation may reveal the presence
of an S4 sound. Pulse pressure will widen, and the systolic pressure will increase because of
stiffening of the blood vessels. The heart rate should decrease.
Picc line vs midline IV? - answer✔midline has a shorter length (ends further from the heart),
midline is temperary. Picc lines are used long term and end within the larger veins within the
heart.
while educating the patient on a diagnostic procedure including a DYE, is it alright to continue
use of Metformin or Jenuvia? - answer✔NO! can cause Renal failure. Should be takin off 3 days
prior (use insulin SUBQ instead) and may resume metformin and jenuvia 48 hours postop.
angiography - answer✔Angiography is an imaging technique that involves the injection of the
contrast agent into the arterial catheter.
