A nurse is caring for a newborn who was delivered by vacuum extraction and has swelling on his head that crosses the suture line. The newborn's mother asks about the swelling on her newborn's head. Which of the following responses should the nurse make?
A. "This is a Mongolian spot, which is found on many newborns.".
A Mongolian spot is a benign, flat, bluish-gray pigmented area often found on the sacral or gluteal area of some newborns with darker skin tones. It is not related to the swelling on the newborn's head caused by vacuum extraction.
B. "This is a caput succedaneum, which is a collection of fluid from pressure of the vacuum extractor.".
A caput succedaneum is a localized swelling on the baby's scalp that occurs due to pressure from the vacuum extractor during delivery. It is typically soft and may cross the suture lines. This explanation accurately describes the swelling the baby has on his head.
C. "This is erythema toxicum, which is a transient allergic reaction that causes edema in the skin.".
Erythema toxicum is a common rash that appears as small red bumps with white or yellow centers. It is a benign and self-resolving condition that does not cause swelling on the head or involve the suture lines.
D. "This is a cephalhematoma, which will resolve on its own in 3 to 5 days.".
A cephalhematoma is a collection of blood between the skull and the periosteum that does not cross the suture lines. It is caused by trauma during birth and may take weeks to months to resolve. This does not match the description of the swelling caused by vacuum extraction.

Full Explanation
"This is a caput succedaneum, which is a collection of fluid from the pressure of the vacuum extractor.”.
Choice A rationale:
A Mongolian spot is a benign, flat, bluish-gray pigmented area often found on the sacral or gluteal area of some newborns with darker skin tones. It is not related to the swelling on the newborn's head caused by vacuum extraction.
Choice B rationale:
A caput succedaneum is a localized swelling on the baby's scalp that occurs due to pressure from the vacuum extractor during delivery. It is typically soft and may cross the suture lines. This explanation accurately describes the swelling the baby has on his head.
Choice C rationale:
Erythema toxicum is a common rash that appears as small red bumps with white or yellow centers. It is a benign and self-resolving condition that does not cause swelling on the head or involve the suture lines.
Choice D rationale:
A cephalhematoma is a collection of blood between the skull and the periosteum that does not cross the suture lines. It is caused by trauma during birth and may take weeks to months to resolve. This does not match the description of the swelling caused by vacuum extraction.
Similar Questions
The nurse enters the room and notices that the room feels cold. The mother says, "He has been crying and kicking and now he seems very tired.”. What is the nurse's priority concern?
A. Metabolic alkalosis.
This condition typically results from excessive loss of acid, often due to vomiting or diuretics. It is not the most likely concern in a cold environment with an infant who has been crying and kicking.
B. Metabolic acidosis.
A cold environment can lead to nonshivering thermogenesis in newborns, where they metabolize brown fat to generate heat. This process can lead to increased lactic acid production, potentially causing metabolic acidosis. The infant's fatigue following crying and kicking may indicate that the body has expended significant energy to stay warm, making metabolic acidosis a priority concern.
C. The infant is hungry.
While hunger could be a reason for crying, it is not the priority concern in this scenario where environmental cold and fatigue are present.
D. The infant is overstimulated.
Overstimulation might cause crying, but the environmental cold and subsequent risk of metabolic acidosis are more critical concerns in this context.

A nurse is reinforcing teaching about phenylketonuria (PKU) testing with the parent of a newborn. Which of the following statements by the parent indicates a need for further teaching?
A. "My baby will be placed under special lights if the test is elevated.".
This statement indicates a need for further teaching. Phenylketonuria (PKU) is a metabolic disorder that leads to the accumulation of phenylalanine in the body. If the PKU test is elevated, it means that the baby has high levels of phenylalanine, and immediate dietary intervention is required. The parent's statement about special lights suggests a confusion with jaundice treatment, which is not related to PKU.
B. "My baby must take formula or breast milk before the test is done.".
This statement is accurate. Before the PKU test is done, the baby needs to consume formula or breast milk to ensure accurate test results.
C. "This test checks for a genetic disorder that can be corrected by diet.".
This statement is also accurate. PKU is a genetic disorder that can be managed with a special diet low in phenylalanine. By adhering to the prescribed diet, the harmful effects of PKU can be minimized.
D. "Sometimes the test is repeated in the doctor's office at the 2-week check-up.".
This statement is accurate. It is common for the PKU test to be repeated at the 2-week check- up to confirm the initial results and ensure early detection and management of PKU if present.

A nurse is collecting data from a newborn. Which of the following anatomical landmarks should the nurse use to measure chest circumference?
A. Sternal notch.
The sternal notch is not an appropriate landmark for measuring chest circumference. It is a notch at the top of the sternum and not indicative of chest circumference.
B. Nipple line.
When measuring the chest circumference of a newborn, the correct anatomical landmark to use is the nipple line. This method ensures that the measurement is taken at a consistent and reproducible location across different individuals, providing an accurate assessment of the chest size relative to growth and development standards. It's important to position the measuring tape at the level of the nipples, encircling the chest at its largest point, which typically aligns with the nipple line.
C. Lower ribcage border.
The lower ribcage border is not suitable as it may vary significantly with respiratory movements and is not a stable landmark for consistent measurements.
D. Axillae.
The axillae (armpits) are not used as a landmark for measuring chest circumference. It is not a standardized anatomical point for this purpose.
