Question 39

A client may be dehydrated due to inadequate fluid intake.

Inadequate fluid intake is a primary cause of dehydration, as it directly leads to reduced body water levels necessary for normal physiological functions.

A) a lack of activity

While a lack of activity can influence hydration levels, it is not a direct cause of dehydration. In fact, sedentary individuals may still maintain adequate hydration if they consume enough fluids. Therefore, this option does not accurately explain a client's dehydration.

B) inadequate fluid intake

This option is correct as inadequate fluid intake is a well-known and direct cause of dehydration. When a person does not consume sufficient fluids, the body cannot maintain its necessary water balance, leading to dehydration.

C) excessive food ingestion

Excessive food ingestion does not inherently cause dehydration. In some cases, consuming food, especially those with high water content, can contribute to hydration. Thus, this option is incorrect in the context of dehydration.

D) a salt-free diet

While a salt-free diet could potentially alter electrolyte balance, it does not directly lead to dehydration. The body can still be hydrated on a salt-free diet if fluid intake is adequate. Therefore, this option does not accurately address the cause of dehydration.

Conclusion

Inadequate fluid intake is clearly the primary factor leading to dehydration, as it directly impacts the body’s hydration status. The other options either do not directly relate to dehydration or may not result in a lack of hydration when proper fluid intake is maintained. Thus, option B is the definitive answer to the question posed.
