Answer to Question 1

A
The QRS segment is an indicator of contraction of the ventricle. If there is ischemia to the ventricle, the impulse will travel more slowly, especially if there are damaged or dead cells along the impulse pathway; therefore, the QRS segment would be prolonged. The P wave is an indicator of atrial activity, not ventricular activity. The T wave is an indication of repolarization of the cardiac tissue, so it would not indicate ventricular ischemia. The PR interval measures the time it takes for the impulse to move from the atria to the ventricles and is not a measure of ventricular ischemia.

Answer to Question 2

D
Douching washes away protective bacteria that protect the vagina from infection, so this behavior will increase the patient's risk of pelvic inflammatory disease. Soaking in a hot bathtub is not likely to result in pelvic inflammatory disease. Daily showers and skipping showers on the weekend will not necessarily cause pelvic inflammatory disease. Wearing cotton underwear helps to wick moisture away from the perineal skin and reduces risk of pelvic inflammatory disease.
