A nurse is caring for a child with moderate dehydration.
What is the appropriate fluid deficit calculation for a child who weighs 12 kg?
Fluid deficit (in mL) = body weight (in kg) x 0.03.
Fluid deficit (in mL) = body weight (in kg) x 0.06.
Fluid deficit (in mL) = body weight (in kg) x 0.1.
Fluid deficit (in mL) = body weight (in kg) x 0.04.
The Correct Answer is D
Choice A rationale:
Fluid deficit (in mL) = body weight (in kg) x 0.03.
Rationale: This calculation significantly underestimates the fluid deficit for a child with moderate dehydration.
Dehydration often requires more significant fluid replacement.
Choice B rationale:
Fluid deficit (in mL) = body weight (in kg) x 0.06.
Rationale: This calculation overestimates the fluid deficit for a child with moderate dehydration.
Using this formula would result in excessive fluid replacement, which can be harmful.
Choice C rationale:
Fluid deficit (in mL) = body weight (in kg) x 0.1.
Rationale: This calculation overestimates the fluid deficit for a child with moderate dehydration.
Using this formula would result in excessive fluid replacement, which can be harmful.
Choice D rationale:
Fluid deficit (in mL) = body weight (in kg) x 0.04.
Rationale: This is The correct answer.
The appropriate fluid deficit calculation for a child who weighs 12 kg with moderate dehydration is to multiply their body weight by 0.04.
For this child, it would be 12 kg x 0.04 = 480 mL.
This formula is a commonly used guideline to estimate fluid deficit in cases of dehydration.

Correct Answer is B
Explanation
Communicate with the healthcare team.
To ensure comprehensive care during the treatment and management of dehydration in children, communication with the healthcare team is essential.
Here's the rationale for this choice:
Choice A rationale:
Administer electrolyte solutions only.
This is not The correct approach.
While administering electrolyte solutions is a vital part of managing dehydration, it is not the only aspect of care.
Comprehensive care also includes assessing the child's overall condition, monitoring vital signs, and addressing any underlying causes of dehydration.
Choice B rationale:
Communicate with the healthcare team.
This is The correct answer.
Dehydration management often requires a multidisciplinary approach.
Communicating with the healthcare team, which may include physicians, dietitians, and other specialists, is crucial to ensure that the child receives appropriate treatment and that any underlying medical issues are addressed.
It also allows for coordinated care and adjustment of the treatment plan as needed.
Choice C rationale:
Rely solely on clinical signs to assess hydration status.
Relying solely on clinical signs is not sufficient for comprehensive care.
While clinical signs are important indicators of hydration status, laboratory tests and monitoring are also necessary to accurately assess and manage dehydration.
Choice D rationale:
Skip monitoring the child's response to treatment.
Skipping monitoring is not advisable.
Monitoring the child's response to treatment is a critical part of dehydration management.
It helps ensure that the child is improving, and adjustments can be made to the treatment plan if necessary.
Correct Answer is B
Explanation
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.
