Exhibit 3. A nurse is reviewing the medical record of a school-age child who has cystic fibrosis.
Which of the following findings should the nurse report to the provider? (Click on the "Exhibit" button for additional information about the client.
There are three tabs that contain separate categories of data.)

Answer is A. Use a 24-gauge catheter to start the IV.

A 24-gauge catheter is the smallest and most appropriate size for an infant's vein¹. It reduces the risk of infiltration, phlebitis, and thrombosis².

B. Start the IV in the infant's foot. Statement is wrong because starting the IV in the foot can interfere with the infant's mobility and increase the risk of infection³. The preferred sites for IV insertion in infants are the scalp, hand, or arm veins⁴.

C. Change the IV site every 3 days. Statement is wrong because changing the IV site every 3 days is not recommended for infants and children. The IV site should be changed only when clinically indicated, such as signs of infection, infiltration, or phlebitis.

D. Cover the insertion site with an opaque dressing. Statement is wrong because covering the insertion site with an opaque dressing can obscure the visibility of the site and prevent early detection of complications. A transparent dressing is preferred as it allows for continuous assessment of the site.

Choice A rationale:

Weighing the child once each month is not the most relevant information to include in teaching parents of a preschool-age child with heart failure. Monitoring weight is important, but it should be done more frequently, preferably daily, to track any sudden weight gain, which could indicate fluid retention and worsening heart failure.

Choice B rationale:

Withholding digoxin if the child's pulse is greater than 100/min is not appropriate. Digoxin is commonly prescribed for heart failure in pediatric patients to strengthen the heartbeat. Instead, the nurse should teach the parents to monitor the child's pulse rate regularly and report any significant changes to the healthcare provider.

Choice C rationale:

Increasing the child's oxygen flow rate until the child no longer has cyanosis is incorrect. While oxygen therapy might be necessary for a child with heart failure, adjusting the oxygen flow rate based on cyanosis is not the appropriate approach. Oxygen therapy should be prescribed and monitored by healthcare providers based on the child's oxygen saturation levels.

Choice D rationale:

Providing for periods of rest is the correct choice. Children with heart failure often tire easily due to the heart's reduced ability to pump blood effectively. Allowing the child to rest helps conserve energy and prevents additional strain on the heart. This instruction promotes the overall well-being and comfort of the child, aligning with the management of heart failure.
