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
Chronic otitis media with effusion (OME) is a condition where fluid accumulates in the middle ear without signs of infection.
This can cause hearing loss, speech delay, and balance problems. The child may complain of a feeling of fullness or pressure in the ear.
Choice A is wrong because a fever as high as 40° C (104° F) is a sign of acute otitis media, which is an infection of the middle ear with inflammation and pus formation.
Choice B is wrong because severe pain in the ear is also a sign of acute otitis media, not chronic otitis media with effusion.
Choice C is wrong because nausea and vomiting are not typical symptoms of chronic otitis media with effusion. They may be associated with other conditions such as gastroenteritis or vestibular disorders.
Correct Answer is C
Explanation
This is because self-monitoring of blood glucose allows children to learn how their blood sugar levels change in response to different factors such as food, exercise, stress, and medication.
It also helps them to adjust their insulin doses and dietary intake accordingly. Self-monitoring of blood glucose can improve glycemic control and reduce the risk of complications.
Choice A is wrong because it is not a less expensive method of testing.
Self-monitoring of blood glucose requires a glucose meter, test strips, lancets, and a logbook, which can be costly for some families.
Choice B is wrong because it is not less accurate than laboratory testing.
Self-monitoring of blood glucose can provide accurate and reliable results if done correctly and regularly.
Laboratory testing is usually done periodically to measure the average blood sugar level over the past 2 to 3 months (hemoglobin A1c).
Choice D is wrong because it implies that the parents are not involved in the child’s diabetes management.
Parents should still provide support and guidance to their children with diabetes, especially when they are young or newly diagnosed. Parents should also monitor their child’s blood glucose levels and help them with insulin administration if needed.
