a.
AV valves closing.
b.
closure of the semilunar valves.
c.
contraction of the papillary muscles.
d.
contraction of the ventricles.
ANS: A

I can ambulate in the hallway with this gadget on.
b.
I always take off the telemetry device when I shower.
c.
My EKG is being watched by one of the nurses in CCU on the home unit.
d.
I am able to sleep just fine with this device on.
ANS: B

inch and refills in 15 seconds. The nurse would document this assessment as:
a.
+1 edema.
b.
+2 edema.
c.
+3 edema.
d.
+4 edema.
ANS: B
A +2 edema can be documented if the skin can be depressed inch and respond within 15
seconds.
• What do dark or cold spots on a thallium scan indicate?
a.
Tissue with adequate blood supply
b.
Dilated vessels
