NU122 Exam 3 With
Solution
Which term describes the heart's ability to generate an electrical impulse at
the SA node? Automaticity describes the ability of the cardiac conduction
system's specialized electrical cells to initiate an electrical impulse
Contractility describes- ANSWER ability of the cardiac conduction system's
specialized electrical cells 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 medication will be administered to dilate the coronary arteries? -
ANSWER adenosine (Adenocard), dipyridamole (Persantine), or dobutamine
(Dobutrex)
Central Venous Pressure greater than 6mmHg - ANSWER hypervolemia or
right sided heart failure (increased ventricular preload)
, Geriatric normal considerations - ANSWER The heart rate will decrease with
age, and heart block can occur due to changes in the conduction system. An
S4 sound may be auscultated. Pulse pressure will widen, and the systolic
pressure increased due to stiffening of the blood vessels. The heart rate
should decrease.
Picc line vs midline IV? - ANSWER The midline is shorter in length-it ends
further from the heart. It is also temporary. The 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
ok 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.
Ventriculography - ANSWER A catheter is inserted into the left ventricle and
a large amount of contrast media (30 mL) is rapidly introduced into the
ventricle.
catheterization possible complications - ANSWER Dysrhythmias (from
