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. "My baby's fingers are looking swollen.": Swelling around the IV site can indicate infiltration, where IV fluids leak into surrounding tissues rather than being infused into the vein.
B. "The tape is coming off the IV needle.": While loose tape may need to be replaced, it does not specifically indicate infiltration.
C. "There's blood backing up my baby's IV tubing.": Blood backflow can indicate various issues such as improper placement or the IV being too low, but not necessarily infiltration.
D. "There's a long red streak up my baby's arm.": A red streak can indicate phlebitis, inflammation of the vein, rather than infiltration, which typically presents with swelling and coolness around the IV site.
Correct Answer is C
Explanation
A. Temporal: The temporal artery is not commonly used for pulse checks in infants as it can be difficult to palpate and may not provide an accurate heart rate.
B. Carotid: The carotid pulse is not recommended in infants due to the risk of compressing the airway or carotid artery, leading to decreased blood flow to the brain.
C. Apical: The apical pulse is the most reliable method for assessing heart rate in infants. It involves auscultating the heart directly at the chest, which provides the most accurate heart rate measurement.
D. Dorsalis pedis: This site is not typically used for pulse checks in infants as it can be difficult to locate and palpate accurately.
