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 D
Explanation
Choice A rationale
Neonatal Abstinence Syndrome (NAS) is a group of problems that occur in a newborn who was exposed to addictive opiate drugs while in the mother’s womb. While NAS can pose risks to a newborn, it is not considered the greatest risk.
Choice B rationale
Developmental Dysplasia of the Hip (DDH) is a condition where the “ball and socket” joint of the hip does not properly form in babies and young children. While DDH can pose risks to a newborn, it is not considered the greatest risk.
Choice C rationale
Subgaleal hemorrhage is a rare but potentially lethal condition in newborns, usually resulting from vacuum-assisted delivery. While it can pose risks to a newborn, it is not considered the greatest risk.
Choice D rationale
Congenital cardiac defects are the most common type of birth defect. They can alter the way blood flows through the heart and pose a significant risk to a newborn.
Correct Answer is C
Explanation
Choice A rationale
While congenital anomalies, growth restriction, and fetal distress during labor can occur in pregnancies, they are not directly associated with polyhydramnios. Polyhydramnios is a condition characterized by an excessive accumulation of amniotic fluid in the uterus during pregnancy.
Choice B rationale
Carrying more than one fetus can lead to a condition known as twin-to-twin transfusion syndrome, which can result in polyhydramnios in one twin and oligohydramnios in the other. However, carrying more than one fetus does not directly mean the mother will experience polyhydramnios.
Choice C rationale
Polyhydramnios is indeed characterized by an excessive amount of amniotic fluid present in the uterus during pregnancy. This can be due to various reasons such as fetal abnormalities, maternal diabetes, and others.
Choice D rationale
An elevated level of alpha-fetoprotein (AFP) in the amniotic fluid can be an indication of certain fetal abnormalities, but it is not a direct indicator of polyhydramnios.
