Answer;

Explanation:

If it is possible to  measure the  time intervals  between consecutive heart beat in milliseconds, and determine how the time intervals varies from time to time, then the value obtained is called Heart Rate Variability. It can be  felt when pulse at the wrist is measured and  deep breath taken and exhale afterwards.

Longer interval is observed during exhalation when the HR is long thus the  heart slows down,while short intervals during fast beat of the heart,with fast HR.It can be detected by ECG through measurement of intervals between R waves( R-R).

HRV is regulated by ANS, through the sympathetic , which increases the heartbeat and therefore reduces the  HRV, and the parasympathetic which reduces the heart beat and therefore increases the HRV, since  the slower beats enabled  easy measurements of  intervals between  consecutive heartbeats.

Therefore,  the variance  in  the R-R waves intervals is determined by the parasympathetic nervous system which slow the heart beats for  higher HRV values to be obtained.The answer is TRUE

Which is the proper order for applying a rigid splint to an injured wrist that is not bleeding.
lidiya [134]

The proper order for applying a rigid splint to an injured wrist that is not bleeding is: Check the fingers for feeling, warmth, and color. Pad the splint; apply the splint; secure the splint; put the arm in a sling; secure the arm; check the fingers for feeling, warmth, and color.

Hence option (c) is correct.

A medical device called a splint is used to prevent an injured body part from moving and to shield it from further harm.

When applied correctly, a rigid splint will ensure that the injured area doesn't move, which will assist reduce discomfort from an accident.

Steps to apply a rigid splint are :

1) Check the fingers of the patient for feeling, warmth, and color.

2) Apply padding: Pad the splint

3) Place the homemade splint carefully so that it rests on both the joint above and below the injury.

4) Secure the splint.

5) Put the arm in a sling

6) Secure the arm

7) Again check the fingers for feeling, warmth, and color.

Therefore option (c) is the proper order for applying a rigid splint to an injured wrist that is not bleeding.
