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 C
Explanation
Magnesium sulfate is given to women with preeclampsia and eclampsia to prevent and treat convulsions.
Magnesium sulfate is a mineral that reduces seizure risks in women with preeclampsia. A healthcare provider will give the medication intravenously. Sometimes, it’s also used to prolong pregnancy for up to two days. This allows drugs that speed up your baby’s lung development to be administered.
Choice A is wrong because magnesium sulfate does not improve patellar reflexes or increase respiratory efficiency. In fact, it may cause decreased or absent deep tendon reflexes and respiratory depression as side effects.
Choice B is wrong because magnesium sulfate does not shorten the duration of labor. It may actually prolong labor by inhibiting uterine contractions.
Choice D is wrong because magnesium sulfate does not prevent a boggy uterus or lessen the lochial flow. It has no effect on uterine tone or bleeding after delivery.
Correct Answer is A
Explanation
“You may need to increase the caloric density of your infant’s formula.” This is because infants with heart failure have increased metabolic needs and may not be able to consume enough volume to meet their nutritional requirements. Increasing the caloric density of the formula can help them achieve adequate growth and development without overloading their heart.
Choice B is wrong because feeding the baby every 2 hours may cause fatigue and dehydration. Infants with heart failure should be fed every 3 to 4 hours or on demand.
Choice C is wrong because increasing the amount of formula may cause fluid retention and worsen heart failure. Infants with heart failure should be fed small, frequent amounts of formula.
Choice D is wrong because placing a nasal oxygen cannula on the infant during and after each feeding may not be necessary or beneficial. Oxygen therapy should be prescribed by a physician based on the infant’s oxygen saturation levels and clinical signs of hypoxia.
