zheka24 [161]

The observation that can be made by the nurse and athletes by measuring the blood pressure is the ability of the arteries to stretch.

<h3>Importance of vital signs to the athlete</h3>

The vital signs are those important body functions, which include the heartbeat, breathing rate, temperature, and blood pressure, that can be used to monitor the treatment of an individual.

The measurement of blood pressure is used to monitor these efficiency of an athlete's cardiovascular system.

Blood pressure measurements reflect:

  • the ability of the arteries to stretch,

  • the volume of circulating blood, and

  • the amount of resistance the heart must overcome when it pumps blood.

Therefore,the observation that can be made by the nurse and athletes by measuring the blood pressure is the ability of the arteries to stretch.

Explanation:

Edema is characterized by an increase in the amount of interstitial fluid in a tissue or within a cavity. The fluid accumulated in edema is formed by an aqueous solution of salts and proteins from the blood plasma.  An edema can have various causes, such as changes in the wall of a capillary, decreased plasma oncotic pressure, increased hydrostatic blood pressure, sodium retention, and decreased lymphatic drainage.

In people who are confined to bed for long periods of time they usually develop edema because blood pressure rises, forcing more fluid into the interstitial spaces as hydrostatic blood pressure increases.
