unit 3 + 4 Study Questions with Correct
Detailed Answers 2025
Pacemakers -Correct Answers ✔-Permanent and temporary.
stimulate contractions.
Atria = P-wave stimulation (spike right before)
Ventricle = QRS stimulation (spike right before)
Dual Pacemaker -Correct Answers ✔-Better than single pacemaker b/c CARDIAC
OUTPUT IS INCREASED AND MINICS HEART MUCH CLOSER than a single
one.
Will see P-wave and QRS complexes for each paced beat (A-V paced).
Transcutaneous Pacemaker (external) -Correct Answers ✔-Temporary,
noninvasive.
Need to give enough sedation and pain meds.
Attached to D-fib and put in pacer mode to shock heart.
Permanent Pacemaker (internal) -Correct Answers ✔-Invasive and need informed
concent for Dr.
Need to explain risks and complications.
Clean chest and make sure it's sterile.
Complications of internal pacemakers -Correct Answers ✔-Malfunctions, leads
can get displaces, battery can die, pneumothorax, can irritate phrenic
nerve/stimulation (hiccups).
A - paced EKG -Correct Answers ✔-Pacing stimulus directed to heart and a pacer
spike is seen on EKG strip. Vertical line followed by a P-wave (atrail pacing)
V - paced EKG -Correct Answers ✔-Pacing stimulus directed to heart and a pacer
spike is seen on EKG strip. Vertical line followed by a QRS complex (ventricular
pacing).

Each pacemaker spike needs to be followed by a... -Correct Answers ✔-complex
(p-wave or QRS)
Failure to Capture -Correct Answers ✔-Electrical charge to myocardium is
insufficient to produce atrial or ventricular contraction.
What can failure to capture result in? -Correct Answers ✔-Serious bradycardia or
asystole.
What causes failure to capture w/ pacemakers? -Correct Answers ✔-Pacer lead
damage, battery failure, dislodgement of electrode, electrical charge set too low,
fibrosis od electrode tip.
What to do if see EKG of pacemaker with no complex? -Correct Answers ✔-
Assess first and then notify Dr. Means electrical charge is not strong enough to
cause contraction.
Pacemaker Placement -Correct Answers ✔-PLaced in the OR or Cath Lab.
24 hr stay.
Left arm should not be lifted more than 90 degrees (no greater than shoulder level).
Pacemaker patient education -Correct Answers ✔-Monitor incision site,
Monitor/check HR 1x/day, always carry pacemaker ID card, NO MRIs
(contraindicated bc of magnet), can't have security wand waved over them (notify
security), can't walk through metal detector.
Notify Dr. if chest pain, palpitations, hiccups, SOB, dizziness.
Cardioversion -Correct Answers ✔-Indicated for fast rhythms w/ a pulse.
Elective procedure - need to have consent, have crash cart ready, enough sedation
and pain medication (can have skin burns)
Prior to a cardioversion procedure... -Correct Answers ✔-Echocardiogram needs to
be done to r/o risk of blood clot dislodgement (placed on anticoagulants)
Internal Cardioversion -Correct Answers ✔-*AICD* - pacemaker w/ ability to
shock.
Pacing capabilities - A paced, V paced, or both.
