Answer to Question 1

D
When the incorrect size cuff is used, it is possible to obtain a false reading. The size selected is proportional to the circumference of the limb being assessed. Ideally select a cuff that is 40 of the circumference (or 20 wider than the diameter) of the midpoint of the limb being used to be obtain measurements. The bladder, enclosed by the cuff, encircles at least 80 of the arm of an adult and the entire arm of a child. A cuff that is wrapped too loosely or unevenly will yield false-high readings.

Answer to Question 2

A
Autonomy refers to a person's independence. As a principle in bioethics, autonomy represents an agreement to respect a patient's right to determine a course of action. Justice refers to the principle of fairness: fair treatment and fair distribution of health care resources. Fidelity refers to the agreement to keep promises and is based on the virtue of caring. Nonmaleficence is actively seeking to do no harm.
