A client is about to receive D10W (10% dextrose in water) as part of their treatment plan.
The nurse explains that this intravenous fluid contains Dextrose 100 g/L and Water 900 mL.
Which of the following statements made by the client indicates a correct understanding of their treatment?

Normal saline (0.9% NaCl).

Choice A rationale:

Normal saline (0.9% NaCl) is the most appropriate choice for a client with cerebral edema.

This isotonic solution is commonly used to maintain intravascular volume and provides a neutral effect on fluid balance in the brain.

It does not introduce additional electrolytes that could potentially worsen cerebral edema.

Choice B rationale:

Half normal saline (0.45% NaCl) is not the best choice for cerebral edema because it is hypotonic and may lead to cellular swelling, potentially exacerbating the edema.

Choice C rationale:

Lactated Ringer's, while isotonic, contains additional electrolytes and lactate.

In the case of cerebral edema, it is safer to use a solution with a simpler composition like normal saline to avoid any potential complications related to electrolyte imbalances.

Choice D rationale:

D5W (5% dextrose in water) is not recommended for cerebral edema because it contains dextrose and may not adequately address the underlying issue of increased intracranial pressure associated with cerebral edema.

Choice A rationale:

"Height and weight.”.

Rationale: While monitoring height and weight is important for a child's growth and development, these parameters are not the primary vital signs to assess dehydration.

Dehydration assessment focuses on immediate physiological indicators, such as heart rate and blood pressure.

Choice B rationale:

"Heart rate and blood pressure.”.

Rationale: This is The correct answer.

When assessing a dehydrated child, monitoring vital signs such as heart rate and blood pressure is crucial.

Dehydration can lead to an increased heart rate and decreased blood pressure.

These parameters provide valuable information about the child's circulatory status and fluid balance.

Choice C rationale:

"Hair and eye color.”.

Rationale: Hair and eye color are not relevant parameters for assessing dehydration.

They are genetic traits and do not change in response to dehydration.

Choice D rationale:

"Shoe size and clothing size.”.

Rationale: Shoe size and clothing size are not relevant for assessing dehydration.

These measurements are related to a child's growth and body structure but do not provide information about their hydration status.
