Calculate the daily fluid requirement in milliliters for a child that weighs 57 pounds. Enter the numeric value and round to the nearest whole number.
The Correct Answer is ["1618"]
Step 1: Convert pounds to kilograms
1 kg = 2.2 lb
57 lb ÷ 2.2 = 25.9 kg
Step 2: Use the Holliday-Segar method
- First 10 kg → 100 mL/kg = 10 × 100 = 1000 mL
- Next 10 kg → 50 mL/kg = 10 × 50 = 500 mL
- Remaining weight: 25.9 – 20 = 5.9 kg
→ 5.9 × 20 mL = 118 mL
Step 3: Total daily fluid requirement
1000 + 500 + 118 = 1618 mL/day
Final Answer: 1618 mL

Correct Answer is A
Explanation
A. The preschool stage (ages 3–6 years) corresponds to Erikson’s stage of Initiative vs. Guilt, where children take initiative in play, imagination, and planning activities. Pretend play, such as planning a tea party, is a hallmark of this developmental stage. It demonstrates creativity, initiative, and the ability to direct their own activities, which shows age-appropriate psychosocial development.
B. Imitation is more characteristic of the toddler stage (Autonomy vs. Shame and Doubt). While preschoolers may still imitate, it is not the primary defining behavior of their Eriksonian stage.
C. Taking apart a toy to understand how it works reflects curiosity and problem-solving more typical of the school-age child (Industry vs. Inferiority), who is focused on mastery and understanding how things function.
D. Building a model requires higher-level fine motor skills, sustained attention, and structured task completion, abilities more aligned with the school-age period rather than preschool development.
Correct Answer is C
Explanation
A. This is not a typical presentation of retinoblastoma. Eye closure can occur with irritability or photophobia but is not a hallmark sign of this condition.
B. Proptosis may occur in advanced retinoblastoma if the tumor grows large or spreads behind the eye, but it is not an early or common presenting symptom. Early detection usually occurs before eye protrusion develops.
C. This is the classic early sign of retinoblastoma, known as leukocoria. Leukocoria is observed as a white reflection in the pupil, especially in photographs taken with flash. It occurs due to light reflecting off the tumor mass in the retina. This symptom is often the first sign noticed by parents and prompts evaluation.
D. Ear tugging is not associated with retinoblastoma. It is more indicative of ear discomfort, such as otitis media, and is unrelated to ocular tumors.
