A nurse is preparing to calculate fluid replacement for a dehydrated child.
Which of the following steps should the nurse take? (Select all that apply).

Choice A rationale:

Gastrointestinal illnesses, particularly diarrhea and vomiting, lead to fluid loss from the body.

Diarrhea can cause significant loss of water and electrolytes, leading to dehydration.

Vomiting, especially when persistent, can also result in fluid depletion.

These conditions are common causes of dehydration in both children and adults.

Choice B rationale:

Excessive sweating during physical activity or in hot weather can lead to dehydration in individuals, but this scenario does not apply to the child described in the question, who is experiencing decreased urine output and dark-colored urine.

Sweating excessively is more common in older children and adults during physical activities.

Choice C rationale:

Fever, which increases the body's fluid requirements, is a valid point.

However, the child in this scenario does not have fever mentioned as a symptom.

In the absence of fever, gastrointestinal illnesses are the more likely cause of dehydration.

Choice D rationale:

Certain medical conditions, such as diabetes or kidney disease, can lead to chronic dehydration.

However, these conditions are not mentioned in the scenario provided.

In the absence of information about underlying medical conditions, gastrointestinal illnesses remain the most likely cause of the child's dehydration.

Choice A rationale:

Gastrointestinal illnesses, including diarrhea and vomiting, lead to fluid loss, significantly contributing to dehydration in children.

Diarrhea increases water and electrolyte loss from the body, while vomiting leads to rapid fluid depletion.

These conditions can be severe, especially in infants and young children, making them prone to dehydration.

Choice B rationale:

Excessive sweating during physical activity or in hot weather can result in significant fluid loss.

Children, especially when engaged in vigorous activities, can sweat profusely, leading to dehydration, especially if fluid intake does not match the loss.

Monitoring fluid balance is crucial during such situations to prevent dehydration-related complications.

Choice C rationale:

Insufficient fluid intake due to poor feeding or decreased thirst perception can lead to dehydration, especially in infants and young children who rely heavily on fluid intake for their hydration needs.

Children may not recognize their thirst or may refuse to drink due to illness, leading to decreased fluid intake.

This can result in dehydration, emphasizing the importance of assessing feeding habits and fluid intake patterns.

Choice D rationale:

Sunken eyes and fontanelle in infants are physical signs of dehydration, not etiological factors.

Sunken eyes are due to decreased tissue turgor, indicating dehydration.

Fontanelle, the soft spot on an infant's head, can appear sunken in dehydration.

These signs are crucial in assessing the severity of dehydration during physical examination but do not contribute to the causes of dehydration.
