42. After reviewing information shown in the accompanying figure from the medical
records of a 43-yr-old patient, which risk factor modification for coronary artery
disease should the nurse include in patient teaching?
a. Importance of daily physical activity
b. Effect of weight loss on blood pressure
c. Dietary changes to improve lipid levels
d. Cardiac risk associated with previous tobacco use
ANS: C
The patient has an elevated low-density lipoprotein cholesterol and low high-
density lipoprotein cholesterol, which will increase the risk of coronary artery
disease. Although the blood pressure is in the prehypertensive range, the patient’s
waist circumference and body mass index indicate an appropriate body weight. The
risk for coronary artery disease a year after quitting smoking is the same as a
nonsmoker. The patient’s occupation indicates that daily activity is at the levels
suggested by national guidelines.

MULTIPLE CHOICE
1. To determine whether there is a delay in impulse conduction through the ventricles,
the nurse will measure the duration of the patient’s
a. P wave. c. PR interval.
b. Q wave. d. QRS complex.
ANS: D
The QRS complex represents ventricular depolarization. The P wave represents the
depolarization of the atria. The PR interval represents depolarization of the atria,
atrioventricular node, bundle of His, bundle branches, and the Purkinje fibers. The
Q wave is the first negative deflection following the P wave and should be narrow
and short.
