The Health Care Provider orders Phenobarbital 3 milligrams per kilogram per day divided in two doses.

Calculate a single dose for a newborn that weighs 3 kilograms.
Do not round your answer.

Choice A rationale

Determining the child's specific vocabulary for body functions and feelings is essential to facilitate effective communication and reduce anxiety during hospitalization. Children with Down syndrome may have delayed or limited expressive language skills, and understanding their individual communication patterns is a foundational nursing action.

Choice B rationale

Assessing hearing and visual capabilities is a critical step because children with Down syndrome have an increased incidence of sensory deficits, such as conductive hearing loss and refractive errors. Identifying these deficits allows the nurse to tailor communication and safety measures to the child's specific sensory needs.

Choice C rationale

Encouraging parents to leave the child alone is contraindicated because children with Down syndrome, like most hospitalized children, benefit greatly from the presence of their primary caregivers to feel secure and reduce separation anxiety. Parental presence promotes emotional well-being and facilitates communication.

Choice D rationale

Maintaining the child's usual meal times is an appropriate and supportive action that promotes a sense of normalcy and control for the child in the unfamiliar hospital setting. Consistency in routines, including feeding schedules, helps minimize anxiety and encourages adequate nutritional intake.

Step 1 is to convert the child's weight from pounds to kilograms:. 33 pounds ÷ 2.2 kg/pound = 15 kg.

Step 2 is to calculate the total milliliters to be transfused per hour using the ordered rate:. 15 kg × 10 mL/kg/hour = 150 mL/hour. The nurse should transfuse the platelets at a rate of 150 milliliters per hour.
