A nurse is admitting an 8-hour-old, term newborn following a cesarean birth. The nurse observes that the newborn’s skin is yellow.
This finding indicates the newborn is experiencing a complication related to which of the following?
Physiologic jaundice.
Maternal/newborn blood group incompatibility.
Maternal cocaine abuse.
Absence of vitamin K. .
The Correct Answer is A
Choice A rationale
Physiologic jaundice is a common condition in newborns, usually appearing between the second and fourth day of life. It is caused by an increase in bilirubin, a substance produced by the breakdown of red blood cells.
Choice B rationale
Maternal/newborn blood group incompatibility can cause jaundice, but it typically appears within the first 24 hours of life.
Choice C rationale
Maternal cocaine abuse can lead to various complications in the newborn, but it does not directly cause jaundice.
Choice D rationale
Absence of vitamin K does not cause jaundice. Vitamin K is given to newborns to prevent bleeding disorders.

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.
Correct Answer is D
Explanation
Choice A rationale
Covering the cord with the diaper can create a moist environment that promotes bacterial growth and delays healing.
Choice B rationale
Washing the cord daily with mild soap and water is not recommended. It’s better to keep the cord dry and clean.
Choice C rationale
Applying petroleum jelly to the cord stump is not advised. It can create a moist environment that can delay the drying and falling off of the stump.
Choice D rationale
Giving a sponge bath until the cord stump falls off is the correct instruction. This prevents the stump from getting wet, which can delay healing and increase the risk of infection.
