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 D
Explanation
choice D. Monitor blood glucose levels frequently and observe closely for signs of hypoglycemia. This is because a macrosomic infant (a newborn who’s much larger than average) is at risk of developing low blood sugar levels after birth, especially if the mother has diabetes. Hypoglycemia can cause neurological damage in the newborn, so it is important to detect and treat it promptly.
Choice A is wrong because leaving the infant in the room with the mother without monitoring the blood glucose levels may miss signs of hypoglycemia and delay treatment.
Choice B is wrong because taking the infant immediately to the nursery may separate the infant from the mother and interfere with breastfeeding, which can help prevent hypoglycemia.
Choice C is wrong because performing a gestational age assessment to determine whether the infant is large for gestational age is not urgent and does not address the risk of hypoglycemia.
Normal ranges for blood glucose levels in term infants are 2.6 mmol/L or higher at any time. A blood glucose level of 2.5 mmol/L or less is considered hypoglycemic.
Correct Answer is B
Explanation
Swimming is one of the best sports for people with hemophilia because it strengthens the muscles without putting stress on the joints. Swimming is also recommended by most sports physicians and hematologists for patients with hemophilia.
Choice A is wrong because soccer is a contact sport that can cause injuries and bleeding episodes in people with hemophilia. Soccer is not recommended by most sports physicians or hematologists for patients with hemophilia.
Choice C is wrong because basketball is also a contact sport that can lead to injuries and bleeding episodes in people with hemophilia. Basketball may be safe for young children, but the risk increases with the intensity of the game.
Choice D is wrong because football is a collision sport that can cause severe injuries and bleeding episodes in people with hemophilia. Football is not recommended by most sports physicians or hematologists for patients with hemophilia.
Normal ranges for hemophilia are:
- Mild hemophilia: 5% to 40% of normal clotting factor
- Moderate hemophilia: 1% to 5% of normal clotting factor
Severe hemophilia: less than 1% of normal clotting factor
