A nurse is calculating maintenance fluids for a child who weighs 18 kg.
According to the Holliday-Segar method, what would be the total maintenance fluid requirement for this child?
Total maintenance fluids = 1800 mL/day.
Total maintenance fluids = 1200 mL/day.
Total maintenance fluids = 1600 mL/day.
Total maintenance fluids = 1400 mL/day.
The Correct Answer is D
The correct answer is Choice B: Total maintenance fluids = 1200 mL/day.
Choice A rationale:
This value exceeds the calculated requirement for a child weighing 18 kg using the Holliday-Segar method.
Choice B rationale:
The Holliday-Segar method calculates maintenance fluids based on weight as follows:
- For the first 10 kg, the requirement is 100 mL/kg.
- For the next 10 kg, the requirement is 50 mL/kg.
Thus, for a child weighing 18 kg:
- First 10 kg: 10 kg x 100 mL/kg = 1000 mL
- Next 8 kg: 8 kg x 50 mL/kg = 400 mL Total maintenance fluid requirement = 1000 mL + 400 mL = 1400 mL/day.
So, actually, the correct answer should be Choice D: 1400 mL/day.
Choice C rationale:
This value is higher than the requirement for 18 kg based on the Holliday-Segar method.
Choice D rationale:
This is the correct calculation based on the method described above: 1000 mL for the first 10 kg plus 400 mL for the next 8 kg totals 1400 mL/day.

Correct Answer is ["B","C","D"]
Explanation
Choice A rationale:
Lactated Ringer's solution is not contraindicated in cases of hyperkalemia.
This solution contains potassium in a relatively low concentration of 4 mEq/L, which is unlikely to significantly impact hyperkalemia.
Choice B rationale:
Lactated Ringer's solution can be contraindicated in cases of hypokalemia.
While it does contain potassium, the concentration is relatively low at 4 mEq/L.
In cases of severe hypokalemia, a more potassium-rich solution might be preferred.
Choice C rationale:
Lactated Ringer's solution can be used in cases of lower GI fluid loss.
It can help replace lost fluids and electrolytes effectively.
Choice D rationale:
Lactated Ringer's solution can be used in cases of upper GI fluid loss.
It helps restore lost fluids and electrolytes.
Choice E rationale:
Lactated Ringer's solution is not contraindicated in cases of lactic acidosis.
In fact, it contains lactate (28 mEq/L), which can be metabolized to bicarbonate and help correct acidosis.
Correct Answer is ["A","C","E"]
Explanation
Choice A rationale:
Administering oral rehydration solution (ORS) is a crucial nursing intervention for a dehydrated child.
ORS helps replenish the lost fluids and electrolytes, making it an effective treatment for dehydration.
Choice B rationale:
Keeping the child in a cold environment is not an appropriate intervention for a dehydrated child.
Dehydration is not related to room temperature, and maintaining a comfortable environment is important, but extreme cold could cause discomfort to the child.
Choice C rationale:
Monitoring the child's vital signs is an essential nursing intervention when caring for a dehydrated child.
Vital signs, including heart rate, respiratory rate, blood pressure, and temperature, can provide important information about the child's condition and hydration status.
Regular monitoring helps in assessing the child's progress and identifying any worsening symptoms.
Choice D rationale:
Providing heavy meals at regular intervals is not an appropriate intervention for a dehydrated child.
As mentioned earlier, heavy meals can be difficult to digest and may worsen dehydration.
It is more important to focus on rehydration with fluids like ORS.
Choice E rationale:
Educating the child and caregivers about dehydration is an important nursing intervention.
Teaching them about the signs and symptoms of dehydration, the importance of ORS, and how to prevent it in the future is essential for the child's well-being and for preventing future episodes of dehydration.
