The nurse is performing an assessment on a child and notes the presence of Koplik’s spots. In which communicable disease are Koplik’s spots present?

Rubella

Measles (rubeola)

Chickenpox (varicella)

Exanthema subitum (roseola)

Answer and Explanation

The Correct Answer is B

Measles (rubeola) is a communicable disease that is characterized by Koplik’s spots, which are clustered, white lesions on the buccal mucosa opposite the lower molars. They appear two to three days before the measles rash and are pathognomonic for measles.

Choice A is wrong because rubella is a different viral infection that causes a mild rash and fever, but does not have Koplik’s spots.

Choice C is wrong because chickenpox (varicella) is caused by the varicella-zoster virus and produces fluid-filled blisters on the skin, not white spots in the mouth.

Choice D is wrong because exanthema subitum (roseola) is caused by the human herpesvirus 6 or 7 and causes a high fever followed by a pink rash on the trunk and neck, but no oral lesions.

Correct Answer is A

Explanation

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.
