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
Choice A rationale
While itching can be a side effect of opioid analgesics, it is not the priority observation. Itching can be uncomfortable for the client, but it is not life-threatening.
Choice B rationale
A temperature of 38.2°C (100.8°F) indicates a low-grade fever. While this should be monitored, it is not the priority observation in this situation.
Choice C rationale
The priority observation is the client’s blood pressure. Opioid epidural analgesia can cause hypotension, which can lead to inadequate perfusion to the mother and the fetus. Therefore, the nurse should prioritize monitoring the client’s blood pressure.
Choice D rationale
Weakness of the lower extremities can be a side effect of epidural analgesia, but it is not the priority observation. The nurse should monitor for this, but it is not as critical as monitoring the client’s blood pressure.
Correct Answer is A
Explanation
Choice A rationale
Methylergonovine is a medication used to prevent postpartum hemorrhage. It works by causing the uterus to contract, which helps to control bleeding and expel any remaining placental fragments.
Choice B rationale
While infection control is important in the postpartum period, methylergonovine is not specifically used to prevent postpartum infection.
Choice C rationale
Methylergonovine does not prevent hypertension. In fact, it can cause hypertension as a side effect.
Choice D rationale
Methylergonovine is not used to prevent thromboembolic events. Its primary use is to prevent and control postpartum hemorrhage.
