A 10-month-old baby weighs 8 kilograms. What is the recommended fluid maintenance rate for this baby?
50.5 mL/hour
33.3 ml/hour
30 ml/hour
25.3 ml/hour
The Correct Answer is B
Calculation:
Determine the recommended daily fluid maintenance for a baby weighing up to 10 kg.
- For the first 10 kg of body weight, the recommended fluid maintenance is 100 mL/kg/day.
Calculate the total daily fluid maintenance for the baby.
Total daily fluid maintenance (mL/day) = Weight (kg) × 100 mL/kg/day
= 8 kg × 100 mL/kg/day
= 800 mL/day.
Convert the total daily fluid maintenance to an hourly rate.
Fluid maintenance rate (mL/hr) = Total daily fluid maintenance (mL/day) / 24 hr/day
= 800 mL / 24 hr
= 33.333... mL/hr.
= 33.3 mL/hr.

Correct Answer is A
Explanation
A. Provide the infant with appropriate clothing and blankets to maintain warmth: Infants have an immature thermoregulatory system, making it harder for them to maintain body temperature. Using appropriate clothing and blankets helps reduce heat loss through radiation, convection, and evaporation, supporting stable core body temperature.
B. Offer the infant a cool beverage to drink frequently: Cool beverages are not appropriate for thermoregulation in infants, especially those not yet on solid food. They primarily rely on breast milk or formula, and fluid intake alone is not effective for managing temperature in infants.
C. Keep the infant in a well-ventilated room with a fan: While ventilation may help regulate temperature in hot environments, the use of fans can increase the risk of hypothermia in infants due to rapid heat loss. Infants should be kept in environments with stable, moderate temperatures.
D. Place the infant in direct sunlight for extended periods of time: Prolonged exposure to direct sunlight can lead to overheating and increases the risk of sunburn or heatstroke in infants. Controlled indoor lighting and indirect sunlight are safer alternatives for light exposure.
Correct Answer is C
Explanation
A. Bring the child to the office for a rapid infusion of deferoxamine: Deferoxamine is the antidote for iron poisoning, but it is reserved for cases confirmed by serum iron levels or clinical severity. Immediate office visits may delay urgent poison center guidance.
B. Give the child syrup of ipecac: Syrup of ipecac is no longer recommended due to poor efficacy and risk of complications such as aspiration or delayed definitive care. Its use is largely abandoned in favor of activated charcoal or gastric lavage in specific situations, guided by poison control.
C. Contact the poison control center: The poison control center provides expert, immediate, evidence-based recommendations tailored to the substance and amount ingested, ensuring proper triage and care.
D. Provide a high-carbohydrate meal. A high-carb meal does not prevent iron absorption or mitigate toxicity. Dietary measures are ineffective once ingestion has occurred and should not delay appropriate treatment.
