A nurse is assessing a newborn. Which of the following should the nurse understand is a clinical manifestation of pyloric stenosis?
Projectile vomiting after feedings.
Absent bowel sounds.
Increased sodium levels.
Golf ball-sized mass over the left quadrant.
The Correct Answer is A
Choice A rationale
Projectile vomiting after feedings is a classic symptom of pyloric stenosis. This occurs because the enlarged pyloric muscle obstructs the passage of food from the stomach to the small intestine.
Choice B rationale
Absent bowel sounds are not typically associated with pyloric stenosis. While this condition affects the gastrointestinal tract, it does not typically cause a complete absence of bowel sounds.
Choice C rationale
Increased sodium levels are not a typical finding in a newborn with pyloric stenosis. In fact, these infants may have low sodium levels due to vomiting.
Choice D rationale
A golf ball-sized mass over the left quadrant is not a typical finding in a newborn with pyloric stenosis. The classic physical examination finding in pyloric stenosis is a palpable “olive-like” mass in the right upper quadrant of the abdomen.

Correct Answer is C
Explanation
Hypoglycemia, or low blood sugar, is a common condition in newborns, especially those born to mothers with diabetes, those who are small for their gestational age, or those who have been stressed during birth. It’s important to monitor the newborn’s serum glucose level and report any abnormalities to the healthcare provider.
Correct Answer is A
Explanation
Choice A rationale
This is the correct answer. In infants of mothers with poorly controlled diabetes, hyperinsulinemia can lead to increased oxygen consumption and metabolic rate, which can contribute to the development of respiratory distress syndrome.
Choice B rationale
Increased blood viscosity is not the most likely cause of respiratory distress in a macrosomic newborn of a mother with poorly controlled diabetes.
Choice C rationale
A brachial plexus injury is a potential complication of delivery for macrosomic infants, but it is not a cause of respiratory distress syndrome.
Choice D rationale
Increased deposits of fat in the chest and shoulder areas can make delivery more difficult and can increase the risk of birth injuries, but they are not the most likely cause of respiratory distress syndrome in a macrosomic newborn of a mother with poorly controlled diabetes.
