WITH DETAILED VERIFIED ANSWERS;
ALREADY GRADED A; 2026
*What's the first thing you do when patient comes back from
pacemaker procedure?* - correct answer- Assess where
pacemaker was implanted, may be red and tender (notify
provider signs of infection), EKG rhythm want to see spikes
(must know if it's fixed rate, on demand, single or double),
patients arm will be in a sling, XRAY before discharge
Does sinus tachycardia impact cardiac output? - correct
answer- If its prolonged may cause decrease in cardiac output
(not filling up the heart that good because its beating so fast)
Elderly patient complains about heart palpitations, telemetry
shows 180-200HR in A-fib. What do you expect in their vital
signs? - correct answer- High heart rate, cool skin, weak
peripheral pulses, ask them what may have caused it
How do you increase CVP and increase BP? - correct answer-
Constrict the vessels
,How do you know capture has occurred? - correct answer-
The waves have occurred (P waves)
How do you know the AV node is working? - correct answer-
40-60 HR
How do you know the SA node is working properly? - correct
answer- 60-100 HR
How do you recognize SVT (supraventricular tachycardia? -
correct answer- >150BPM, narrow rhythm, P waves may not
be visible, different shape, narrow QRS, may be paroxysmal -
affects atrium
How to calculate heart rate on an ekg strip? - correct answer-
QRS x 10
How to read an EKG strip? - correct answer- See if there's a
PQRST with rest, rate, check rhythm if it's regular
If CVP is high or BP is high, will there be a high resistance? -
correct answer- Yes, more afterload
, If patient is in V-tach, the potassium is 2. What do you do? -
correct answer- IV potassium
If the blood pressure is low, what is the CVP? - correct answer-
low CVP
PACs vs PVCs? - correct answer- PACs (P wave is off), PACs
(QRS is off)
Patient diagnosed with PACs, scared they might have cardiac
arrest, how do you educate patient? - correct answer- PACs
aren't harmful, asymptomatic
True or false A-fib is the most common dyrhythmia: - correct
answer- true
What actions do you take for A-fib? - correct answer- Initiate
continuous monitoring, prepare for cardioversion if
antidysrhythmic isn't effective
What are complications from A-fib? - correct answer- PE,
DVT, weakened ventricle turning into heart failure
