A pediatric nurse is calculating a child's medication dosage. The child weighs 30 kilograms and the prescribed dosage is 0.2 milligrams per kilogram. How many milligrams of medication should the nurse administer to the child?

A. Check for iodine or shellfish allergies prior to the procedure: Cardiac catheterization often involves the use of a contrast dye that contains iodine. If the child has an allergy to iodine or shellfish, there is an increased risk of an allergic reaction to the dye.

B. Place an NPO status for 12 hours prior to the procedure: NPO status typically is required for a few hours before a procedure involving anesthesia or sedation, but not necessarily for 12 hours. The specific time frame should be determined by the healthcare provider.

C. Elevate the affected extremity following the procedure: After cardiac catheterization, the affected extremity should typically be kept straight and immobilized to prevent bleeding or hematoma formation. Elevating the extremity may not be advisable.

D. Limit fluid intake following the procedure: After cardiac catheterization, the child should be encouraged to drink fluids to help flush the contrast dye from their system, unless contraindicated by other factors.

A. "He is always hungry.": This is not typically a sign of a congenital heart defect. Many infants are hungry frequently as they grow, so this would not be an alerting sign.

B. "He is fussy for several hours every day.": Fussiness is common in infants and does not necessarily indicate a congenital heart defect.

C. "He tires out during feedings.": This is a concerning sign. Infants with congenital heart defects often have difficulty feeding due to poor oxygenation and energy reserves. Fatigue during feedings is a common symptom of heart defects.

D. "He sleeps all the time.": Sleeping a lot could be normal for a 1-month-old infant, and it would not necessarily indicate a congenital heart defect unless the infant is lethargic or difficult to rouse.
