The nurse explains that the medication Prostaglandin E1 is being given to their child with transposition of the great vessels to:

A. Introducing new foods every day does not allow sufficient time to monitor for adverse reactions.

B. Waiting 8 to 10 days between introducing new foods is a longer interval than typically recommended. It may unnecessarily delay the introduction of a variety of foods to the infant's diet.

C. 5 to 7 days.

When introducing new foods to an infant, it's important to do so gradually to monitor for any potential allergic reactions or sensitivities. Waiting 5 to 7 days between introducing new foods allows for observation of any adverse reactions, such as allergies or digestive issues. This approach helps in identifying the specific food responsible for any adverse reactions and ensures the infant's safety.

D. Waiting 2 to 3 days is too short of an interval to adequately monitor for adverse reactions. Waiting 5 to 7 days provides a better balance between introducing new foods and monitoring for potential issues.

A. Lordosis: Lordosis is an excessive inward curvature of the spine, typically seen in the lower back. It is often referred to as "swayback."

B. Torticollis: Torticollis is a condition where the head is tilted to one side and may be rotated to the opposite side. It typically affects the neck muscles and is not related to lateral curvature of the spine.

C. Scoliosis.

Scoliosis is a lateral curvature of the spine. It is characterized by an abnormal sideways curvature of the spine, which can lead to an "S" or "C" shape of the spine. Scoliosis can occur during adolescence, and routine physical examinations may reveal this condition.

D. Kyphosis: Kyphosis is an excessive outward curvature of the spine, which can result in a rounded or hunched back, often seen in the upper back or thoracic spine.

In summary, the lateral curvature of the spine observed in this adolescent should be documented as scoliosis.
