1. A nurse is conducting a health assessment of a patient

who has a history of hypertension and diabetes. The nurse

wants to measure the patient's blood pressure using a

sphygmomanometer and a stethoscope. Which of the

following steps should the nurse follow to ensure accurate

measurement?

a) Wrap the cuff around the patient's upper arm, leaving a

gap of 2 cm between the cuff and the elbow.

b) Inflate the cuff until the pressure is 20 mmHg above the

patient's estimated systolic pressure.

c) Deflate the cuff at a rate of 2 to 3 mmHg per second,

listening for the first and last Korotkoff sounds.

d) Record the systolic and diastolic pressures as even

numbers, rounding up or down as needed.

* c) Deflate the cuff at a rate of 2 to 3 mmHg per second,

listening for the first and last Korotkoff sounds.

Rationale: This is the correct procedure for measuring

blood pressure using a sphygmomanometer and a

stethoscope. The first Korotkoff sound indicates the

systolic pressure, and the last Korotkoff sound indicates the

diastolic pressure. The other options are incorrect because

they may introduce errors or biases in the measurement.

2. A nurse is evaluating the effectiveness of an educational

program on wound care for patients with diabetes. The

nurse uses a pre-test and post-test design to measure the

patients' knowledge before and after the program. Which of

the following statistical tests should the nurse use to

analyze the data?
