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.

Answer and Explanation

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 C

Explanation

Children with asthma who are taking long-term inhaled steroids should be assessed frequently to monitor for this increased risk because some studies have shown a growth delay in children treated with moderate to high doses of inhaled steroids. This appears to occur only during the first year of treatment and may be reversible.

Choice A is wrong because cough is not a side effect of inhaled steroids, but a symptom of asthma itself.

Choice B is wrong because osteoporosis is not a common side effect of inhaled steroids in children, but a possible risk for adults who use high doses of inhaled steroids or oral steroids.

Choice D is wrong because Cushing’s syndrome is not a side effect of inhaled steroids, but a rare complication of oral steroids.

A. Apply an oil-based lotion to the newborn’s skin to prevent drying and cracking. B. Limit the newborn’s intake of milk to prevent nausea, vomiting, and diarrhea. C. Place eye shields over the newborn’s closed eyes. D. Change the newborn’s position every 4 hours.

Correct Answer is C

Explanation

Placing eye shields over the newborn’s closed eyes. This is because phototherapy can cause eye damage and irritation to the newborn, so eye protection is essential.

Choice A is wrong because oil-based lotion can increase the absorption of heat and cause burns to the newborn’s skin.

Choice B is wrong because limiting the newborn’s intake of milk can cause dehydration and increase the risk of hyperbilirubinemia.

Choice D is wrong because changing the newborn’s position every 4 hours is not frequent enough to prevent pressure ulcers and ensure even exposure to the light.

Normal ranges for bilirubin levels in newborns are 1 to 12 mg/dL for term infants and 3 to 14 mg/dL for preterm infants. Phototherapy is usually indicated when the bilirubin level exceeds 15 mg/dL for term infants and 10 mg/dL for preterm infants.
