The most important reason to protect the preterm infant from cold stress is that:

It could make respiratory distress syndrome worse.

Shivering to produce heat may use up too many calories.

A low temperature may make the infant less able to digest nutrients.

Cold decreases circulation to the extremities.

Answer and Explanation

The Correct Answer is A

A) It could make respiratory distress syndrome worse:
The most critical reason to protect a preterm infant from cold stress is that hypothermia can exacerbate respiratory distress syndrome (RDS). Cold stress leads to an increased oxygen demand, which can worsen the infant’s already compromised respiratory function. In preterm infants, the immature lungs and underdeveloped surfactant production contribute to RDS, and hypothermia worsens the situation by increasing metabolic demands and impairing pulmonary function. Maintaining a stable body temperature is crucial for minimizing respiratory complications.

B) Shivering to produce heat may use up too many calories:
While it is true that preterm infants may not have the metabolic reserves to generate heat via shivering (as they lack significant brown fat), the primary concern is not shivering. Preterm infants generally do not shiver, and cold stress does not trigger this response. Instead, their body tries to conserve heat through vasoconstriction and increased metabolism, which can lead to hypoxia and worsening respiratory distress.

C) A low temperature may make the infant less able to digest nutrients:
Cold stress can affect a preterm infant’s gastrointestinal function by reducing blood flow to the digestive organs, which can impair nutrient absorption and digestion. However, the most immediate and serious consequence of cold stress is the increased metabolic demand and worsening of respiratory distress, rather than a direct impact on digestion. Protecting the infant from hypothermia helps prevent these secondary complications.

D) Cold decreases circulation to the extremities:
While cold stress can indeed lead to vasoconstriction and decreased circulation to the extremities, this is not the most significant concern. The primary issue with cold stress in preterm infants is the overall increase in metabolic demands, oxygen consumption, and exacerbation of respiratory problems, which can lead to more severe respiratory distress syndrome. The loss of peripheral circulation is a secondary concern.

Correct Answer is A

Explanation

A. Mother Rh-, baby Rh+:
Rh immune globulin (RhoGAM) is given to Rh-negative mothers after childbirth if the baby is Rh-positive. This is to prevent the mother from developing antibodies against Rh-positive blood cells, which could affect future pregnancies. If the mother’s immune system recognizes Rh-positive cells as foreign, it may start producing antibodies that can cross the placenta and harm future Rh-positive fetuses, potentially leading to hemolytic disease of the newborn. Administering RhoGAM prevents this sensitization from occurring.

B. Mother Rh-, baby Rh-:
If the mother is Rh-negative and the baby is also Rh-negative, there is no risk of Rh incompatibility. Since there is no Rh-positive blood in the mix, the mother will not develop antibodies against Rh-positive cells. Therefore, Rh immune globulin is not needed in this situation.

C. Mother Rh+, baby Rh+:
If the mother is Rh-positive, there is no risk of Rh incompatibility regardless of the baby’s Rh status. Rh-positive mothers do not produce antibodies against Rh-positive blood cells, so RhoGAM is unnecessary in this scenario.

D. Mother Rh+, baby Rh-:
Again, since the mother is Rh-positive, there is no risk of sensitization, even if the baby is Rh-negative. In this situation, the mother's immune system will not generate antibodies against Rh-negative blood cells, and RhoGAM is not needed.

A. Skin to Skin contact B. Swaddling the infant C. Allowing family members to hold infant D. None of the above

Correct Answer is A

Explanation

A) Skin to Skin contact:
Skin-to-skin contact, also known as "kangaroo care," is a highly beneficial practice for both the mother and the infant in the immediate postpartum period. It promotes bonding by enhancing emotional connections, helps the infant maintain their body temperature through the transfer of warmth from the mother’s chest, and supports the initiation of breastfeeding, which is essential for the infant's nourishment. Additionally, skin-to-skin contact stimulates the release of oxytocin, which can aid in uterine contractions and promote involution of the uterus.

B) Swaddling the infant:
While swaddling the infant can provide comfort and a sense of security, it does not directly promote bonding or help with temperature regulation as effectively as skin-to-skin contact does. Swaddling can help the infant feel secure and prevent the startle reflex but does not have the same physiological benefits in terms of promoting involution or maintaining body temperature.

C) Allowing family members to hold the infant:
While allowing family members to hold the infant can help with bonding, it does not offer the same immediate physical benefits as skin-to-skin contact between the mother and infant. Skin-to-skin contact is particularly beneficial in terms of temperature regulation and promoting the early stages of breastfeeding, which can help with the involution of the uterus.

D) None of the above:
This option is incorrect because skin-to-skin contact has been shown to promote bonding, help regulate the infant's temperature, and support postpartum recovery processes, including uterine involution.
