a. Deflating the cuff at 2 mm Hg per second
b. Having the patient sit down for the measurement
c. Using the same time each day for the measurement
d. Taking the blood pressure reading after the patient comes back from a walk

Question 2

Answer to Question 1

D

Feedback
A The cuff should be deflated at a rate of 2 mm Hg per second.
B When possible, the patient should be sitting in a chair for the blood pressure reading.
C The blood pressure should be assessed at the same time each day.
D The patient's blood pressure should not be measured after the patient has exercised, smoked, or ingested caffeine. After any of these instances, the patient should wait 30 minutes before assessment of the blood pressure.

Answer to Question 2

D
The client's pH is elevated at 7.48 (normal, 7.35 to 7.45), the CO2 is normal at 42 (normal, 35 to 45 mm Hg), and the bicarbonate is elevated at 32 (normal, 22 to 26 mmol/L). The client is expe-riencing metabolic alkalosis.
In metabolic acidosis, the client's pH would be below 7.35, and the bicarbonate would be below 22 mmol/L. The client is not experiencing metabolic acidosis.
In respiratory acidosis, the client's pH would be below 7.35, and the CO2 would be elevated above 45 mm Hg. The client is not experiencing respiratory acidosis.
In respiratory alkalosis, the client's pH would be above 7.45, and the CO2 would be below 35 mm Hg. The client is not experiencing respiratory alkalosis.
