A nurse is preparing a presentation about ways to minimize heat loss in the newborn. Which measure would the nurse include to prevent heat loss through convection?

using a radiant warmer to transport a newborn

placing a cap on a newborn's head

placing the newborn skin-to-skin with the mother

closing doors and windows to prevent draft

Answer and Explanation

The Correct Answer is D

A. Using a radiant warmer to transport a newborn helps prevent radiant heat loss, not convection. Radiant heat loss occurs when heat transfers from the newborn to cooler surfaces not in direct contact, such as walls or windows.
B. Placing a cap on a newborn's head is effective in reducing evaporative and radiant heat loss from the head, but it does not specifically address heat loss through air movement (convection).
C. Placing the newborn skin-to-skin with the mother reduces conductive heat loss by providing a warm surface (the mother's skin), not convection.
D. Closing doors and windows to prevent draft helps reduce convective heat loss, which occurs when air currents pass over the newborn's skin and carry away body heat. Eliminating drafts minimizes this form of heat loss, making this the correct intervention for convection.

Correct Answer is D

Explanation

A. 25mg/hr is incorrect. The question asks for the volume in mL/hr, not the dose in milligrams per hour.
B. 25g/hr is incorrect. The ordered dose is 1g/hr, not 25g/hr.
C. 250mL/hr would provide a much higher dose than ordered, based on the concentration.
D. 25mL/hr is correct. This is the calculated volume to deliver the 1g/hr maintenance dose based on the supplied concentration. Volume= Ordered dose/ Concentration

Determine the concentration of the solution: The supplied concentration is 20g/500mL, which simplifies to 0.04g/mL (since 20g = 20,000mg and 500mL = 500mL).

Determine the ordered dose: The order is for a maintenance dose of 1g/hr.

Calculate the volume to be infused: 1/0.04= 25mL/hr

A. cephalhematoma. B. molding C. microcephaly D. caput succedaneum

Correct Answer is D

Explanation

A. Cephalhematoma refers to a collection of blood between the baby's skull and the periosteum (the membrane covering the bone), which does not cross the suture lines. It typically occurs after a traumatic delivery, but it is not diffuse edema like caput succedaneum.

B. Molding refers to the shaping of the baby’s head to fit through the birth canal during delivery. It involves temporary changes to the skull bones (such as overlapping sutures) but does not involve edema or soft tissue swelling.

C. Microcephaly is a condition where a newborn's head is abnormally small, usually due to developmental issues, and it has nothing to do with edema or swelling of the soft tissues.

D. Caput succedaneum is the correct term for diffuse edema of the newborn’s scalp that crosses the suture lines. It is caused by the pressure during delivery as the baby's head moves through the birth canal, and it typically resolves within a few days after birth.
