Question

which of the following is a characteristic of electronic sphygmomanometers? they require the use of a stethoscope. some types also measure pulse and oxygen saturation. the mercury rises with an increase in pressure as the cuff is inflated. they are the least expensive type of sphygmomanometer. they have a circular gauge for registering pressure. question 7 1 point mrs. reeves is a 57 - year - old patient who was brought to the office because she has been having frequent dizzy spells. in addition to the routine vital signs, which of the following would you expect the physician to ask you to perform for this patient? orthostatic vital signs capillary refill time pupil reactivity gait tests elbow and knee reflexes

Explanation:

1. For the first question about electronic sphygmomanometers:

• Traditional sphygmomanometers may require a stethoscope, but not electronic ones.
• Some advanced electronic sphygmomanometers can measure pulse and oxygen - saturation in addition to blood pressure.
• Mercury rising with pressure is a feature of mercury - based sphygmomanometers, not electronic ones.
• Electronic sphygmomanometers are not necessarily the least expensive type.
• Having a circular gauge is more typical of aneroid sphygmomanometers, not electronic ones.

1. For the second question about Mrs. Reeves with dizzy spells:

• Orthostatic vital signs measure blood pressure and heart rate in different positions (sitting, standing) and can help identify if low blood pressure upon standing (orthostatic hypotension) is causing the dizziness. Capillary refill time is more related to circulation in general, pupil reactivity to neurological function related to the eyes, gait tests to balance and neurological function related to movement, and elbow and knee reflexes to neurological function of the spinal cord and peripheral nerves. Since the main symptom is dizziness, orthostatic vital signs are a likely additional test.

Answer:

First question: Some types also measure pulse and oxygen saturation.
Second question: orthostatic vital signs
