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
Ulcerative colitis is a chronic inflammatory bowel disease that causes diarrhea, pain, and bleeding in the colon. Stress and certain foods can trigger or worsen the symptoms, so it is important to teach the mother how to help her son cope with stress and avoid triggers.
Choice A is wrong because ulcerative colitis is not an infectious disease that can spread to others.
Choice B is wrong because ulcerative colitis causes diarrhea, not constipation. Nutritional guidance is important, but not the main focus of teaching.
Choice C is wrong because the daily use of enemas is not part of the treatment plan for ulcerative colitis. Enemas can irritate the colon and cause more inflammation.
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.
