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?
