Pacemaker Basics on the NCLEX
Indications, types, capture/sensing, patient teaching.
Pacemakers stimulate the heart electrically. NCLEX tests indications and teaching.
Indications
Symptomatic bradycardia. Heart blocks (2nd degree type 2, 3rd degree). Some HF (CRT).
Failure to capture
Pacer spike but no QRS. Increase output.
Failure to sense
Pacing despite native beats. Increase sensitivity.
Teaching
Avoid strong magnetic fields (MRI generally contraindicated unless MRI-compatible pacer). Cell phone in opposite pocket. Notify TSA. Pulse check daily.
Frequently asked
