A patient is obese. At the bedside is a standard-size blood pressure cuff. The nurse realizes that the use of this cuff will provide which of the following?
 
  a. Accurate readings as long as it is 20 of the circumference of the midpoint of the limb.
  b. Indistinct readings if the bladder encircles 80 of the adult's arm.
  c. A falsely low reading if the cuff is wrapped too loosely around the arm.
  d. Inaccurate readings and needs to be replaced with a larger cuff.

Question 2

A 73-year-old patient with hypertension is awaiting a triple cardiac bypass surgery. The patient is hard of hearing and did not understand what the surgeon said regarding the surgery.

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.
