Question

Hydration status can be determined by paying attention to various indicators. Read the statements below and select the correct statements regarding how to assess hydration. Select all that apply.a. Weighing the body before and after exercise can be used to detect overhydration and dehydration.b. Reduced saliva production can be an indicator of dehydration.c. Dark urine can be an indicator of water imbalance.d. None of these

Answer 1

To assess hydration status, weighing before and after exercise, monitoring saliva production, and observing the color of urine are effective indicators. Physical changes in the body as a response to dehydration trigger thirst and involve ADH in regulating kidney function.

Step-by-step explanation:

When it comes to assessing hydration status, certain indicators can provide valuable information. The correct statements regarding how to assess hydration status are:

• Weighing the body before and after exercise can be used to detect overhydration and dehydration due to changes in body water content.
• Reduced saliva production can be an indicator of dehydration, signaling a decrease in serous output and an increase in thicker mucus, resulting in a dry mouth sensation.
• Dark urine can be an indicator of a water imbalance, as the kidneys concentrate or dilute urine based on the body's hydration levels.

These methods are part of a broader understanding of dehydration and hydration management. Dehydration occurs when water loss exceeds intake and is signalled by physiological responses such as increased blood osmolality, which triggers the thirst response. Also, the antidiuretic hormone (ADH) plays an essential role in the regulation of body water levels by signaling the kidneys to recover water from urine.

Answer 2

Correct options are (a), (b) and (c).

Step-by-step explanation:

Water is the important component of the body. Human body consists of more than 60% of water. Most solutes and physiological mechanism depend on the water present inside the body.

The dehydration or loss of water can cause deadly disease in humans. It is important to maintain the hydration level of the body. The hydration status can be checked by the urine color as the light color indicates the enough amount of water in the body. Weight of the body before and after exercise also expresses the hydration status. The reduced saliva indicates the dehydration condition of the body.

Thus, correct options are (a), (b) and (c).
