The nurse is caring for a newborn born at 30 weeks' gestation.
Which assessment finding should the nurse anticipate?
Plantar creases over the entire sole.
Flexion of all four extremities.
Abundance of subcutaneous fat deposits.
Lanugo covering most of the body.
The Correct Answer is D
Choice A rationale
Plantar creases appear over the entire sole closer to term gestation (37-40 weeks). At 30 weeks, these creases are confined to the anterior sole, reflecting the immature integumentary system. Absence of full creases correlates with preterm gestational age, assisting in clinical age assessment of neonates.
Choice B rationale
Preterm neonates at 30 weeks exhibit hypotonia, with minimal extremity flexion. Flexion develops progressively as the central nervous system matures. Hypotonia reflects developmental immaturity and is a distinguishing feature in preterm infants compared to term neonates.
Choice C rationale
Subcutaneous fat deposition is limited in preterm neonates, contributing to their thin, translucent skin and increased risk of thermoregulation issues. Fat accumulation occurs primarily in the third trimester, and its absence is a hallmark of premature neonates, requiring external temperature support.
Choice D rationale
Lanugo, a fine hair covering the body, is prominent in neonates born at 30 weeks. It serves as an adaptive mechanism for thermoregulation in utero. Lanugo decreases closer to term as subcutaneous fat increases. Its presence confirms preterm status and aids in gestational age assessment.

Correct Answer is B
Explanation
Choice A rationale
Positioning the infant supine increases pressure on the surgical site, potentially disrupting healing or increasing the risk of cerebrospinal fluid leakage. Supine positioning is contraindicated immediately after myelomeningocele repair as it can compromise the integrity of the repair.
Choice B rationale
Monitoring head circumference detects signs of hydrocephalus, a common complication after myelomeningocele repair due to cerebrospinal fluid dynamics. Enlarging head circumference can indicate increased intracranial pressure and require immediate intervention to prevent further neurological damage.
Choice C rationale
Intake and output monitoring provides essential hydration and renal function data post-surgery. While important, it is not the priority intervention immediately following surgery, as it does not directly address complications such as hydrocephalus or infection risk.
Choice D rationale
Maintaining skin integrity prevents infection and promotes healing but does not address potential neurological complications. While this intervention remains vital for recovery, it is secondary to detecting hydrocephalus or fluid imbalances post-surgery.
Correct Answer is ["B","C","D"]
Explanation
Choice A rationale
A large bruise on the forehead of a 2-year-old could occur from accidental falls, which are common at this developmental stage due to increased mobility and decreased coordination. It does not necessarily suggest abuse unless accompanied by other suspicious findings.
Choice B rationale
Circular abrasions around the wrists are highly indicative of physical abuse as they suggest binding injuries. Restraining a child is neither acceptable nor normal, and such findings must be reported for further investigation by child protective services.
Choice C rationale
A burn on the palm of a 10-year-old’s hand raises concerns for abuse as accidental burns usually occur on accessible areas like arms or legs, not the palm. This pattern could indicate intentional infliction, requiring mandatory reporting to authorities.
Choice D rationale
Splash burns on the front torso in a 6-year-old are suspicious if inconsistent with the child’s developmental abilities or history provided by caregivers. Intentional scald burns often follow specific patterns, like splash marks, and must be reported for investigation.
