What is the hourly fluid maintenance rate for a 13.5 kg child?
109 ml per hour.
79 ml per hour.
49 ml per hour.
200 ml per hour.
The Correct Answer is C
Choice A reason: A 109 ml/hour rate is excessive for a 13.5 kg child. Using the 4-2-1 rule (4 ml/kg/hour for the first 10 kg, 2 ml/kg/hour for the next 3.5 kg), the total is 47 ml/hour, not 109, which could cause fluid overload and cardiovascular strain.
Choice B reason: A 79 ml/hour rate overestimates maintenance fluids for a 13.5 kg child. The 4-2-1 rule yields 47 ml/hour (40 ml for 10 kg + 7 ml for 3.5 kg). Higher rates risk hypervolemia, potentially causing pulmonary edema or electrolyte imbalances in a child.
Choice C reason: For a 13.5 kg child, the 4-2-1 rule calculates maintenance fluids as 40 ml/hour (10 kg × 4 ml) + 7 ml/hour (3.5 kg × 2 ml) = 47 ml/hour, closest to 49 ml/hour. This rate maintains hydration without risking fluid overload, supporting renal and cardiovascular function.
Choice D reason: A 200 ml/hour rate is far too high for a 13.5 kg child, risking fluid overload, heart failure, or pulmonary edema. The correct maintenance rate, per the 4-2-1 rule, is approximately 47 ml/hour, making this choice dangerously excessive for pediatric fluid needs.

Correct Answer is A
Explanation
Choice A reason: During a tonic-clonic seizure with vomiting, positioning the child side-lying is critical to prevent aspiration. Seizures cause uncontrolled muscle contractions, potentially obstructing the airway with vomit. The lateral position allows gravity to drain secretions, reducing the risk of aspiration pneumonia, which can lead to severe hypoxia and respiratory failure if not addressed promptly.
Choice B reason: Placing a pillow under the head may slightly elevate it but does not mitigate the immediate aspiration risk from vomiting. It could restrict neck movement, complicating airway management. Aspiration is a life-threatening emergency, as it can cause rapid oxygen desaturation, making this action less urgent than ensuring airway patency.
Choice C reason: Clearing hazards prevents injuries from seizure-induced movements, such as hitting objects. However, it is secondary to airway management when vomiting occurs. Aspiration can cause immediate respiratory distress, leading to hypoxia and potential brain damage, so positioning takes precedence over environmental safety measures.
Choice D reason: Loosening restrictive clothing reduces chest constriction, aiding breathing during a seizure. While beneficial, it does not address the immediate risk of aspiration from vomiting. Airway protection is critical to prevent pulmonary complications, such as pneumonia, which can arise from aspirated material, making this action less urgent.
Correct Answer is B
Explanation
Choice A reason: Simple spasm seizures involve brief muscle contractions, not daydreaming-like episodes. These seizures, seen in conditions like infantile spasms, cause sudden jerking movements, unlike the brief staring spells of absence seizures, which align with the described pencil-dropping and unresponsiveness.
Choice B reason: Absence seizures cause brief episodes of unresponsiveness, often with staring, lasting seconds, resembling daydreaming. Common in children, they involve generalized epileptiform activity in the brain, interrupting attention, leading to actions like dropping objects, with rapid return to normal activity.
Choice C reason: Non-epileptic seizures are psychogenic, triggered by stress, not neurological dysfunction. They may mimic seizures but lack epileptiform brain activity. The described brief, stereotypical episodes suggest a neurological cause, like absence seizures, rather than a psychological origin.
Choice D reason: Akinetic seizures cause sudden loss of muscle tone, leading to falls, not just dropping objects with a daydreaming appearance. These seizures involve brief atonic episodes, differing from the staring and unresponsiveness characteristic of absence seizures in the described scenario.
