A client is concerned about their child's dehydration and seeks medical advice.
The child is lethargic and irritable.
What diagnostic evaluations might the healthcare provider perform to assess the child's condition, as mentioned in the text?
Vital signs, including heart rate, blood pressure, and temperature.
Physical examination findings, such as skin turgor and mucous membrane moisture.
Laboratory tests, including complete blood count (CBC), electrolyte levels, and urine specific gravity.
Assessing the child's history, including recent fluid intake, urine output, and presence of symptoms.
The Correct Answer is C
Choice A rationale:
Vital signs are essential in assessing dehydration.
An elevated heart rate may indicate compensatory mechanisms due to decreased intravascular volume.
Low blood pressure may suggest severe dehydration, and abnormal temperature may indicate an underlying infection.
These parameters provide crucial information about the child's circulatory status, helping to assess the severity of dehydration.
Choice B rationale:
Physical examination findings, such as skin turgor and mucous membrane moisture, are valuable indicators of dehydration.
Poor skin turgor, where the skin doesn't return to its normal position promptly when pinched, indicates decreased tissue turgor due to fluid loss.
Dry mucous membranes, including the mouth, suggest dehydration and help evaluate the extent of fluid deficit.
These signs offer direct visual clues about the child's hydration status.
Choice C rationale:
Laboratory tests play a significant role in diagnosing dehydration.
A complete blood count (CBC) helps identify elevated hematocrit levels, indicating hemoconcentration due to fluid loss.
Electrolyte levels, specifically sodium and potassium, provide insights into the child's electrolyte balance, which can be disrupted in dehydration.
Urine specific gravity measures the kidney's ability to concentrate urine; a high specific gravity suggests concentrated urine due to reduced fluid intake.
These tests aid in confirming the diagnosis and assessing the severity of dehydration.
Choice D rationale:
Assessing the child's history is fundamental in understanding the underlying cause of dehydration.
Recent fluid intake and urine output patterns help determine the balance between intake and output.
Symptoms such as diarrhea, vomiting, and fever indicate potential causes of fluid loss.
Additionally, evaluating the child's overall health and any recent illnesses provides context for the dehydration, guiding appropriate treatment.

Correct Answer is ["A","B","C","D"]
Explanation
Choice A rationale:
Thirst and dry mouth are early signs of dehydration.
When the body loses fluids, it signals the brain to increase thirst and conserve water.
Dry mouth can occur due to reduced saliva production when the body is dehydrated.
Choice B rationale:
Decreased urine output and dark-colored urine are indicators of concentrated urine, suggesting dehydration.
Reduced fluid intake or excessive fluid loss can lead to decreased urine production, and the urine becomes more concentrated, appearing darker than usual.
Choice C rationale:
Rapid heart rate and low blood pressure are signs of hypovolemic shock, a severe form of dehydration where the body cannot circulate enough blood to meet its needs.
This can happen in severe cases of dehydration when there is a significant loss of fluids and electrolytes.
Choice D rationale:
Poor skin turgor is a classic clinical sign of dehydration.
Skin turgor refers to the skin's ability to return to its normal position after being pinched.
In dehydrated individuals, the skin loses elasticity and remains tented or "pinched" after being pulled up.
This indicates a lack of fluid in the body.
Choice E rationale:
Increased energy and playfulness are not typical signs of dehydration.
Dehydrated children are more likely to be lethargic and irritable due to the physiological stress on their bodies.
Correct Answer is ["A","C","E"]
Explanation
Sunken fontanelle (in infants).
C. Dry mucous membranes.
E. Lethargy.
Choice A rationale:
Sunken fontanelle (in infants) is a clinical sign of dehydration.
The fontanelle is the soft spot on an infant's head, and when it becomes sunken, it suggests that the child is dehydrated.
This occurs because a lack of adequate fluid causes the brain to temporarily shrink, leading to the sunken appearance.
Choice B rationale:
Increased urine output is not typically a sign of dehydration.
In fact, dehydration often leads to decreased urine output as the body attempts to conserve fluid.
Increased urine output can be a sign of other conditions, such as diabetes.
Choice C rationale:
Dry mucous membranes are a classic sign of dehydration.
When the body lacks sufficient fluids, the mucous membranes in the mouth and other areas can become dry and sticky.
This is an important clinical indicator of dehydration.
Choice D rationale:
Normal skin turgor is not a sign of dehydration.
Skin turgor refers to the skin's ability to bounce back when pinched and released.
In a hydrated individual, the skin should have good turgor.
Dehydration can lead to poor skin turgor, but normal skin turgor does not indicate dehydration.
Choice E rationale:
Lethargy is a potential sign of dehydration.
When a child is dehydrated, they may become lethargic or unusually tired because their body is not receiving the necessary fluids to function properly.
Lethargy can be an early sign of dehydration in children.
