A child who weighs 25 kg receives a prescription for isoniazid 10 mg/kg/day by mouth once a day.
The bottle is labeled "isoniazid Oral Solution, USP 50 mg per 5 mL.”. How many mL should the nurse administer? (Enter numerical value only.
If rounding is required, round to the nearest whole number.)
The Correct Answer is ["25"]
Step 1: Calculate the total daily dose in mg: 25 kg × 10 mg/kg/day = 250 mg/day.
Step 2: Determine how many mL are needed to administer the 250 mg dose: (250 mg ÷ 50 mg) × 5 mL = (5) × 5 mL = 25 mL. Final calculated answer: 25 mL.v

Correct Answer is ["B","C","E"]
Explanation
Choice A rationale
While placing pillows inside the side rails can prevent injury, it may not be effective if the child is having a severe tonic-clonic seizure, as the child could still injure themselves. Padding the entire bed with approved padding is more appropriate in such a case.
Choice B rationale
During a seizure, it is crucial to ensure the child’s safety by asking the mother to release the child to prevent unintentional injury. Holding the child down during a seizure can cause harm to both the child and the mother, and it's important to provide a safe space for the child to move.
Choice C rationale
Administering an anticonvulsant medication can help control the seizure and prevent further convulsions. Medications such as benzodiazepines are often used to treat ongoing seizures and can provide rapid relief.
Choice D rationale
Closing the blinds to darken the room is not directly beneficial during a seizure and does not address the immediate need to protect the child from injury or manage the seizure effectively. While reducing light may help in other conditions, it is not a priority during a seizure.
Choice E rationale
Monitoring the child's airway and tongue is critical to ensure they are not at risk of choking or aspiration during a seizure. Keeping the airway clear and observing for any obstructions can prevent further complications and ensure the child’s safety.
Correct Answer is A
Explanation
Choice A rationale
Projectile vomiting in an infant with an olive-like mass in the abdomen suggests pyloric stenosis. This condition causes severe vomiting due to gastric obstruction. It's a hallmark symptom and requires monitoring and surgical intervention.
Choice B rationale
While arching the back can occur in various conditions, it is not specifically indicative of pyloric stenosis. It could be a sign of discomfort or other neurological issues but not directly related to the gastrointestinal obstruction seen in pyloric stenosis.
Choice C rationale
Frequent pauses during feeding are common in many infant conditions and are not specific to pyloric stenosis. They indicate general feeding difficulties but are not diagnostic of this particular condition.
Choice D rationale
Coffee-ground emesis indicates bleeding in the gastrointestinal tract but is not typical of pyloric stenosis. The hallmark sign is non-bloody, forceful vomiting due to gastric outlet obstruction.
