Question

question 18
which of the following is a characteristic of aneroid sphygmomanometers?
they are very costly and difficult to maintain.
they will give a reading down to one - tenth of a degree.
they provide a digital readout of the blood pressure.
they have a circular gauge for registering pressure.
they are least likely to give an accurate reading.
question 19
1 point
which of the following could increase a patients pulse?
exposure to cold
fever
pain medication
sleeping
weight loss

Explanation:

For Question 18: Aneroid sphygmomanometers have a circular gauge for registering pressure. They are not overly costly or difficult to maintain, don't give readings down to one - tenth of a degree, are not digital, and can give accurate readings when properly calibrated.
For Question 19: Fever can increase a patient's pulse as the body's metabolic rate rises. Exposure to cold usually decreases the pulse, pain medication can sometimes slow it, sleeping generally lowers it, and weight loss alone doesn't typically increase the pulse in the short - term.

Answer:

Question 18: They have a circular gauge for registering pressure.
Question 19: fever
