The nurse teaches a pregnant woman about the presumptive, probable, and positive signs of pregnancy.
The woman demonstrates understanding of the nurse's instructions if she states that a positive sign of pregnancy is:.

 

Choice A rationale:

Drying the baby after birth and wrapping the baby in a dry blanket helps prevent evaporative heat loss. Newborns have a high surface area-to-body mass ratio, making them vulnerable to heat loss through evaporation. Keeping them dry and warm helps maintain their body temperature within the normal range (around 97.8-99.1°F or 36.5-37.3°C).

Choice B rationale:

Avoiding drafts and air conditioners is important to prevent convective heat loss, not evaporative heat loss. Convective heat loss occurs when warm air around the baby is replaced by cooler air, leading to heat loss.

Choice C rationale:

Placing the baby away from the outside wall and windows is related to radiant heat loss, not evaporative heat loss. Radiant heat loss occurs when the baby loses heat to a colder surface without direct contact.

Choice D rationale:

Warming the stethoscope and the nurse's hands before touching the baby is important for preventing conductive heat loss, not evaporative heat loss. Conductive heat loss happens when the baby comes into direct contact with a colder object or surface.

Choice A rationale:
Increasing the caloric density of the infant's formula may be necessary in certain situations, but it is not specific to managing heart failure. Heart failure in infants often leads to poor feeding, so increasing the amount of formula given at each feeding is more appropriate.
Choice B rationale:
Feeding the baby every 2 hours may be necessary for infants, but it is not directly related to managing heart failure. The crucial aspect in heart failure management is optimizing the nutritional intake, which may involve adjusting the amount of formula given to the infant.
Choice D rationale:
Placing a nasal oxygen cannula on the infant during and after each feeding might be necessary if the infant has respiratory distress, but it is not a general recommendation for all infants with heart failure. The focus should be on improving feeding to enhance caloric intake.
Choice C rationale:
This is the correct answer. In heart failure, infants may have difficulty feeding due to fatigue and increased energy demands. Increasing the amount of formula at each feeding can help ensure that the infant receives an adequate calorie intake, promoting growth and development. Monitoring the infant's weight gain and overall condition is essential to assess the effectiveness of this intervention.
