West Coast EMT Block One Exam

Which physical change typically occurs in early adults?

1. Increase in height because of spinal disc expansion.

2. Increase in fatty tissue, which leads to weight gain.

3. Increase in respiratory rate due to increased metabolism.

4. Increase in muscle strength and reflexes.

The correct answer is: Increase in fatty tissue, which leads to weight gain.

In early adulthood, individuals often experience an increase in fatty tissue, which can lead to weight gain. This is largely due to changes in metabolism, lifestyle choices, and hormonal shifts that occur during this stage of life. Many people may find that their physical activity levels decrease or that their dietary habits change, contributing to the accumulation of body fat. While muscle strength and reflexes may improve during this period, the significant observable change is often the increase in body fat, especially as people transition into different life responsibilities that may affect their exercise routines and nutritional habits. Height typically stabilizes after adolescence, so significant increases in height are not expected during early adulthood. Changes in respiratory rate are not typically noted in early adults related to metabolism in such a direct way. These factors together highlight why the increase in fatty tissue is the most relevant change noted in this demographic.
