NCM 118 Skills Midterm Exam ACTUAL
QUESTIONS AND CORRECT ANSWERS
ELECTROCARDIOGRAM, OR ECG - CORRECT ANSWER is a reading assessing the
magnitude and direction of the electrical currents of the heart, and measuring the depolarization and
depolarization of the cardiac
muscle cells.
Depolarization - CORRECT ANSWER corresponding contraction of myocardial muscle moves
as a wave through the heart
Repolarization - CORRECT ANSWER return the ions to their previous resting state, which
corresponds with relaxation of the myocardial.
ECG ELECTRODE PLACEMENT - CORRECT ANSWER is standardized, allowing for the
recording of an accurate trace - but also ensuring comparability between records taken at different
times.
THE P WAVE - CORRECT ANSWER corresponds to an electrical impulse traveling through
the atria. this is synonymous with atrial depolarization and usually corresponds with atrial contraction.
THE QRS COMPLEX - CORRECT ANSWER corresponds to the depolarization of the left and
right ventricles. it generally corresponds to the contraction of the ventricles.
THE T WAVE - CORRECT ANSWER corresponds to repolarization of the ventricles.
SINUS RHYTHM - CORRECT ANSWER is regular with normal p, q-r-s, t deflections, and
intervals. rate = 60-100 at rest.
SINUS BRADYCARDIA - CORRECT ANSWER is a sinus rhythm with a rate of less than 60
per minute in an adult
