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
Turning the client onto her side is the first action the nurse should take when late decelerations are noted on the fetal monitor. Late decelerations can indicate uteroplacental insufficiency, and turning the client onto her side can improve placental blood flow and oxygen delivery to the fetus.
Choice B rationale
Increasing the client’s IV fluid infusion rate can help increase maternal blood volume and improve placental perfusion. However, it is not the first action to take when late decelerations are noted.
Choice C rationale
Palpating the client’s uterus can provide information about the strength, duration, and frequency of contractions, but it is not the first action to take when late decelerations are noted.
Choice D rationale
Administering oxygen to the client can increase the amount of available oxygen for fetal oxygenation. However, it is not the first action to take when late decelerations are noted.
Correct Answer is B
Explanation
Choice A rationale
While a pattern of contractions can be a sign of labor, it is not the definitive sign of true labor. Contractions may also occur in false labor, also known as Braxton Hicks contractions. These contractions do not lead to changes in the cervix.
Choice B rationale
Changes in the cervix, including effacement (thinning) and dilation (opening), are the definitive signs of true labor. During true labor, contractions lead to progressive changes in the cervix, which allow for the baby to be born.
Choice C rationale
Rupture of the membranes, or “water breaking,” can occur in both true labor and false labor. Therefore, it is not the definitive sign of true labor.
Choice D rationale
The station of the presenting part refers to the position of the baby’s head (or other presenting part) in relation to the mother’s pelvis. While the station can change during labor as the baby descends into the pelvis, it is not the definitive sign of true labor.
