A nurse is preparing to administer a dexamethasone 1.5 mg/kg/day PO to divide equally every 6 hr to a preschool-age child who weighs 22 lb. Available is dexamethasone oral solution 1 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["3.8"]
Convert the child’s weight to kg:
22 lb ×1kg/2.2lb = 10 kg
Calculate the daily dose:
1.5 mg/kg/day × 10 kg=15mg/day
Divide the total daily dose by the number of doses per day (every 6 hours):
15mg/day ÷ 4doses/day =3.75mg/dose
Convert the dose to mL using the concentration:
3.75mg × 1 mL/1 mg = 3.75 mL
Round to the nearest tenth:
3.75 mL≈ 3.8 mL
Answer: The nurse should administer 3.8 mL per dose.

Correct Answer is A
Explanation
A. Heart rate 110/min: A heart rate of 110 beats per minute is within the normal range for a 4-year-old child. The typical heart rate for this age is between 80 to 120 beats per minute.
B. Capillary refill greater than 3 seconds: Capillary refill time should be less than 2 seconds in a healthy child. A refill time greater than 3 seconds may indicate poor perfusion or dehydration, which is abnormal.
C. Weight gain of 0.9 kg (2 lb) in a year: A weight gain of 2 pounds in a year is below the expected range for a 4-year-old. Children in this age group typically gain around 4-5 pounds per year as they grow.
D. Respiratory rate 32/min: The normal respiratory rate for a 4-year-old child is typically between 20 to 30 breaths per minute. A rate of 32/min is slightly elevated and may indicate respiratory distress or other issues.
Correct Answer is A
Explanation
A. "You should bring the infant's favourite blanket to the hospital." Bringing the infant's favourite blanket can provide comfort and a sense of security in an unfamiliar hospital environment. It helps the child feel more at ease and can reduce anxiety and stress associated with hospitalization.
B. "You should begin to manipulate the infant's bedtime based on the hospital’s visiting hours." Disrupting the infant’s usual sleep routine can lead to increased stress and irritability. It is better to maintain familiar routines as much as possible to provide comfort and stability during the hospital stay.
C. "You should read the child a story about hospitalization." At 8 months, an infant may not comprehend stories about hospitalization. Reading stories is more effective for older children who can understand and process the information. The focus for infants should be on comfort and familiarity.
D. "You will need to go home when it is not visiting hours." Parents are typically encouraged to stay with their young children in the hospital whenever possible. Parental presence is crucial for the infant’s emotional well-being and can help reduce anxiety.
