A nurse is caring for a pediatric patient with suspected dehydration.
The child presents with diarrhea and vomiting.
What clinical manifestations would the nurse expect to observe in this patient?

“Severe dehydration, which is ≥10% loss of body weight.”.

Choice A rationale:

Mild dehydration is typically classified as a 3-5% loss of body weight.

The signs and symptoms described in the scenario, such as dry mucous membranes, decreased urine output, and decreased skin turgor, are indicative of more severe dehydration than a 3-5% loss.

Choice B rationale:

Moderate dehydration is generally considered to be a 6-9% loss of body weight.

However, the signs and symptoms presented in the scenario suggest a more severe state of dehydration.

Choice C rationale:

Severe dehydration is classified as a loss of ≥10% of body weight.

The signs and symptoms observed by the nurse, including dry mucous membranes, decreased urine output, and decreased skin turgor, are consistent with severe dehydration, making choice C The correct classification.

Choice D rationale:

No dehydration is defined as less than a 3% loss of body weight.

The clinical manifestations observed in the child, as described in the scenario, clearly indicate dehydration.

In this case, the child's signs and symptoms align with the classification of severe dehydration, which is characterized by a loss of ≥10% of body weight.

These symptoms include dry mucous membranes, decreased urine output, and decreased skin turgor.

It's crucial to recognize the severity of dehydration accurately to initiate the appropriate treatment and prevent complications.

Choice A rationale:

Normal saline (0.9% NaCl).

Rationale: Normal saline is the most appropriate choice for a client with dehydration and hyponatremia.

It provides a balanced solution with sodium and chloride, which can help correct hyponatremia and rehydrate the client.

It is an isotonic solution and is commonly used for fluid resuscitation.

Choice B rationale:

Half normal saline (0.45% NaCl).

Rationale: Half normal saline is also an isotonic solution, but it contains less sodium than normal saline.

In a case of hyponatremia, it's better to use a solution with a higher sodium concentration, making choice A (normal saline) more appropriate.

Choice C rationale:

Lactated Ringer’s.

Rationale: Lactated Ringer's is another isotonic solution, but it may not be the best choice for a client with hyponatremia.

It contains lactate, which can be metabolized to bicarbonate, potentially worsening the client's hyponatremia.

Therefore, it's not the most appropriate option in this case.

Choice D rationale:

D5W (5% dextrose in water).

Rationale: D5W is a hypotonic solution and should not be used for rehydration in a client with hyponatremia.

It can exacerbate the electrolyte imbalance and is not suitable for addressing dehydration.
