The nurse is assessing a 40-week-gestation infant. What action by the nurse prevents heat loss through conduction?

Warm the stethoscope before use.

Move the infant away from a drafty vent.

Dry the infant with a towel.

Close the doors to the isolate.

Answer and Explanation

The Correct Answer is A

Choice A reason: Warming the stethoscope before use prevents heat loss through conduction. Conduction is the transfer of heat from the infant's body to a cooler surface or object that comes in direct contact with them. By warming the stethoscope, the nurse ensures that the infant does not lose heat to the cold surface of the stethoscope, thereby helping to maintain the infant's body temperature.

Choice B reason: Moving the infant away from a drafty vent helps prevent heat loss through convection, not conduction. Convection is the transfer of heat through air currents, and keeping the infant away from drafts helps minimize this type of heat loss.

Choice C reason: Drying the infant with a towel prevents heat loss through evaporation. When a wet infant is dried, it helps reduce the loss of heat that occurs as moisture evaporates from the skin.

Choice D reason: Closing the doors to the isolate helps prevent heat loss through radiation. Radiation is the transfer of heat from the infant's body to cooler surrounding surfaces. By closing the doors, the nurse helps maintain a warm environment, reducing heat loss.

Correct Answer is A

Explanation

Choice A reason: Lack of prenatal care is a significant risk factor for neural tube defects, including myelomeningocele, because it often means the mother did not receive important prenatal vitamins like folic acid, which are crucial for proper neural tube development. Prenatal care provides essential screenings and supplements to support a healthy pregnancy and fatal development. Without it, the risk of congenital anomalies, such as myelomeningocele, increases significantly. Additionally, prenatal care helps in identifying and managing other risk factors and conditions that may affect both maternal and fatal health.

Choice B reason: While active Labor with wounds requires medical attention and may pose risks to both mother and baby, it does not directly correlate with an increased risk of myelomeningocele. Myelomeningocele is a congenital condition related to neural tube development early in pregnancy. The presence of wounds in active Labor may indicate complications such as trauma or infection, but these are not associated with neural tube defects.

Choice C reason: Premature rupture of membranes (PROM) is a condition where the amniotic sac ruptures before Labor begins, potentially leading to preterm birth and infections. While PROM is a concern and requires appropriate medical intervention, it is not directly linked to the development of myelomeningocele. The causes of PROM and neural tube defects like myelomeningocele are different, with PROM often related to issues with the amniotic sac or maternal infections.

Choice D reason: Precipitous Labor, which is an unusually rapid Labor and delivery, can pose risks such as trauma to the birth canal and complications for the newborn, but it is not associated with an increased risk of myelomeningocele. The speed of Labor and delivery is not a contributing factor to neural tube defects. Instead, precipitous Labor is more concerning for potential delivery complications and the need for rapid medical response.

A. Misoprostol B. Magnesium Sulphate C. Butorphanol D. Metoprolol E. Tint

Correct Answer is B

Explanation

Choice A reason: Misoprostol is used to induce Labor and is not typically used to manage irregular contractions at 32 weeks gestation.

Choice B reason: Magnesium Sulphate is often used in cases of preterm Labor to relax the uterine muscles and prevent contractions, thereby helping to delay delivery and reduce the risk of complications for the baby.

Choice C reason: Butorphanol is a pain reliever and is not typically used to manage irregular contractions in pregnancy.

Choice D reason: Metoprolol is a beta-blocker used to treat high blood pressure and other heart conditions, but it is not used to manage irregular contractions in pregnancy.

Choice E reason: "Tint" is not a medication and does not relate to the management of irregular contractions in pregnancy.
