Which infant would be more likely to have Rh incompatibility?
Infant of an Rh-negative mother and a father who is Rh-positive and homozygous for the Rh factor.
Infant who is Rh negative and whose mother is Rh negative.
Infant of an Rh-negative mother and a father who is Rh-positive and heterozygous for the Rh factor.
Infant who is Rh positive and whose mother is Rh positive.
The Correct Answer is A
choice A.
Infant of an Rh-negative mother and a father who is Rh-positive and homozygous for the Rh factor.
Rh incompatibility occurs when a woman is Rh-negative and her baby is Rh-positive. This can cause hemolytic disease of the neonate (HDN), a condition where the mother’s antibodies destroy the baby’s red blood cells.
Choice B is wrong because if both the mother and the baby are Rh-negative, there is no risk of Rh incompatibility.
Choice C is wrong because if the father is heterozygous for the Rh factor, there is a 50% chance that the baby will be Rh-negative and not affected by Rh incompatibility.
Choice D is wrong because if both the mother and the baby are Rh-positive, there is no risk of Rh incompatibility.

Correct Answer is B
Explanation
A way to establish rapport. Doing a simple magic trick using gauze is a way to gain the child’s trust and attention, and to make the dressing change less stressful and more fun. This is appropriate for a 5-year-old child who is in the stage of initiative versus guilt according to Erikson’s theory of psychosocial development.
Choice A is wrong because 5-year-old children are curious and imaginative, and they enjoy magic tricks and fantasy play.
Choice C is wrong because a simple magic trick is not too distracting, but rather a way to engage the child and reduce anxiety.
Choice D is wrong because a simple magic trick is not inappropriate due to the child’s cognitive development. According to Piaget’s theory of cognitive development, 5-year-old children are in the preoperational stage, which means they can use symbols and language to represent objects and events.
A magic trick using gauze is a symbolic representation of something else, which the child can understand and appreciate.
Correct Answer is A
Explanation
choice A. Surfactant improves the ability of your baby’s lungs to exchange oxygen and carbon dioxide.
Surfactant is a substance that coats the inner surface of the alveoli, the tiny air sacs in the lungs.
It reduces the surface tension of the alveoli and prevents them from collapsing during exhalation.
Premature infants often lack enough surfactant, which leads to respiratory distress syndrome (RDS).
Artificial surfactant is given to these infants to help them breathe more easily. Choice B is wrong because surfactant has nothing to do with sedation.
Sedation is a state of reduced consciousness induced by drugs. Surfactant does not affect the level of consciousness of the infant.
Choice C is wrong because surfactant is not used to reduce episodes of periodic apnea.
Periodic apnea is a condition where the infant stops breathing for a short time, usually due to immature brainstem function.
Surfactant does not affect the brainstem or the control of breathing.
Choice D is wrong because surfactant is not used to fight a possible respiratory tract infection. Surfactant does not have any antibacterial or antiviral properties.
Surfactant is used to treat RDS, which is caused by a lack of surfactant, not by an infection.
