A nurse is conducting discharge teaching to parents about the care of their infant after cardiac surgery. The nurse instructs the parents to notify the physician of what conditions occur. (Select all that apply.).

To calculate the estimated date of confinement (EDC) using Nagele's rule, follow these steps:

1. Take the first day of the last menstrual period (LMP).

2. Add 7 days to that date.

3. Count back 3 months.

4. Add 1 year to the resulting date, and that will be the EDC.

In this case, the client's LMP started on December 1.

1. December 1

2. December 8 (adding 7 days)

3. September 8 (counting back 3 months)

4. Add 1 year: September 8 of the following year

So, the most accurate EDC for the client using Nagele's rule would be September 8 of the following year.

The correct answer is choiceD. Give small amounts of favorite fluids frequently to prevent dehydration.

Choice A rationale:

Giving tepid water baths to reduce fever is not the most effective intervention for an infant with an upper respiratory tract infection and elevated temperature. While tepid baths can help lower body temperature, they are not as effective as antipyretic medications like acetaminophen or ibuprofen.Additionally, frequent fluid intake is more critical to prevent dehydration, which is a common concern in infants with fever.

Choice B rationale:

Encouraging food intake to maintain caloric needs is important, but it is not the primary concern in this scenario. Infants with upper respiratory infections often have reduced appetites due to congestion and discomfort.Ensuring adequate fluid intake is more crucial to prevent dehydration, which can occur quickly in infants.

Choice C rationale:

Having the child wear heavy clothing to prevent chilling is not recommended. Overdressing can actually increase body temperature and discomfort.It is better to dress the infant in lightweight clothing and use a light blanket if needed to keep them comfortable while allowing their body to regulate temperature more effectively.

Choice D rationale:

Giving small amounts of favorite fluids frequently to prevent dehydration is the most appropriate intervention. Infants with upper respiratory infections and fever are at risk of dehydration due to increased fluid loss from fever and reduced fluid intake.Offering small, frequent amounts of fluids helps maintain hydration and can also soothe the throat and reduce discomfort.
