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.

Answer and Explanation

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

Give small amounts of favorite fluids frequently to prevent dehydration.

Dehydration is a common complication of upper respiratory tract infections in infants, especially if they have a fever. Giving small amounts of fluids frequently can help maintain hydration and electrolyte balance.

Some additional information about the other choices are:

Choice A is wrong because tepid water baths are not recommended for fever reduction. They can cause shivering, which increases heat production and can raise the

temperature further. Instead, antipyretics such as acetaminophen or ibuprofen can be given as prescribed.

Choice B is wrong because food intake may be decreased due to poor appetite, difficulty breathing, or sore throat. Forcing food intake can cause vomiting or aspiration. Fluid intake is more important than caloric intake during an acute infection.

Choice C is wrong because heavy clothing can increase heat retention and discomfort. The infant should be dressed in light clothing and the room temperature should be comfortable.

A. Abdominal rigidity and pain on palpation B. Rounded abdomen and hypoactive bowel sounds C. Visible peristalsis and weight loss D. Distention of lower abdomen and constipation

Correct Answer is C

Explanation

Visible peristalsis and weight loss. These are symptoms of pyloric stenosis, which is a thickening or narrowing of the pylorus, a muscle in the stomach that blocks food from entering the small intestine. Babies with pyloric stenosis often have forceful vomiting, which may cause dehydration.

Choice A is wrong because abdominal rigidity and pain on palpation are not typical signs of pyloric stenosis.

They may indicate other conditions such as appendicitis or bowel obstruction.

Choice B is wrong because a rounded abdomen and hypoactive bowel sounds are also not specific for pyloric stenosis.

They may be seen in other causes of vomiting or abdominal distension.

Choice D is wrong because distention of the lower abdomen and constipation are not related to pyloric stenosis.

They may be due to other problems such as Hirschsprung’s disease or intestinal atresia. Normal ranges for weight gain in infants depend on their age, sex, and feeding method. Generally, infants should gain about 25 to 35 grams per day in the first 3 months of life.
