The nurse is caring for an infant with suspected pyloric stenosis. Which clinical manifestation would indicate pyloric stenosis?

Abdominal rigidity and pain on palpation

Rounded abdomen and hypoactive bowel sounds

Visible peristalsis and weight loss

Distention of lower abdomen and constipation

Answer and Explanation

The Correct Answer is C

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.

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.

A. Respiratory rate of 36 breaths/minute at rest B. Appetite slowly increasing C. Temperature above 37.7° C (100° F) D. New, frequent coughing E. Turning blue or bluer than normal

Correct Answer is ["C","D","E"]

Explanation

The parents should notify the physician if the infant has a temperature above 37.7° C (100° F), new frequent coughing, or turning blue or bluer

than normal. These are signs of infection, respiratory distress, or cyanosis, which could indicate complications after cardiac surgery.

Choice A is wrong because a respiratory rate of 36 breaths/minute at rest is within the normal range for an infant.

Choice B is wrong because an appetite slowly increasing is a positive sign of recovery and does not require immediate attention.
