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 A
Explanation
Choice A rationale
If a client reports feeling down and sad, having no energy, and wanting to cry, the nurse’s priority action should be to ask the client if she has considered harming her newborn. This is because these symptoms may indicate postpartum depression, a serious condition that can lead to harm to both the mother and the baby if left untreated.
Choice B rationale
While reinforcing postpartum and newborn care discharge teaching is important, it is not the priority action in this situation. The client’s emotional health needs to be addressed first.
Choice C rationale
Assisting the family to identify prior use of positive coping skills in family crises can be helpful, but it is not the priority action in this situation. The client’s immediate emotional health needs to be addressed first.
Choice D rationale
Anticipating a prescription by the provider for an antidepressant may be part of the treatment plan for this client, but it is not the priority action. The nurse first needs to assess the safety of the client and her newborn.
Correct Answer is D
Explanation
Choice A rationale
The largest fetal diameter passing through the pelvic outlet is not what is indicated by the presenting part being at 0 station. This would be more indicative of a positive station, such as
+31.
Choice B rationale
The position of the fetal head, such as left occiput posterior, is not determined by the station of the presenting part. The station refers to the level of the presenting part in relation to the mother’s ischial spines.
Choice C rationale
The palpability of the posterior fontanel is not related to the station of the presenting part. The fontanels are soft spots on the baby’s head which allow for compression during birth and brain growth after birth.
Choice D rationale
This is the correct interpretation of the clinical finding. The presenting part is at 0 station when its lowermost portion is at the level of an imaginary line drawn between the client’s ischial spines.
