    B. Extended posture when at rest.
    C. Testes descended into scrotum.
    D. Ability to move his elbow past his sternum.
    C. Testes descended into scrotum.

     full-term male infant will have both testes in his scrotum and rugae on his scrotum.
    (this multiple choice question has been scrambled)
  34. T/F: A newborn male, estimated to be 39 weeks of gestation, would exhibit extended posture when at rest.
    F: The newborn’s good muscle tone will result in a more flexed posture when at rest.
  35. T/F: A newborn male, estimated to be 39 weeks of gestation, would exhibit a moderate amount of lanugo over his entire body.
    F: The newborn will exhibit only a moderate amount of lanugo, usually on his shoulders and back.

    During human development, the lanugo grows on fetuses as a normal part of gestation, but is usually shed and replaced by vellus hair at about 33 to 36 weeks of gestational age. As the lanugo is shed from the skin, it is normal for the developing fetus to consume the hair with the fluid, since it drinks from the amniotic fluid and urinates it back into its environment. Subsequently, the lanugo contributes to the newborn baby's meconium. The presence of lanugo in newborns is a sign of premature birth.

    A hypothesis, according to the NHS, is that the lanugo of human fetuses has to do with temperature regulation.
  36. A newborn would OR would not have the ability to move his elbow past midline.
    would not
  37. While examining a newborn, the nurse notes uneven skinfolds on the buttocks and a click sound when performing the Ortolani maneuver. The nurse recognizes these findings as a sign that the newborn probably has:

    A. Webbing
    B. Hip dysplasia.
    C. Polydactyly.
    D. Clubfoot.
    B. Hip dysplasia.

    The Ortolani maneuver is used to detect the presence of hip dysplasia.

    The Ortolani test or Ortolani maneuver is part of the physical examination for developmental dysplasia of the hip, along with the Barlow maneuver. It relocates the dislocation of the hip joint that has just been elicited by the Barlow maneuver. It is performed by an examiner first flexing the hips and knees of a supine infant to 90 degrees, then with the examiner's index fingers placing anterior pressure on the greater trochanters, gently and smoothly abducting the infant's legs using the examiner's thumbs. A positive sign is a distinctive 'clunk' which can be heard and felt as the femoral head relocates anteriorly into the acetabulum.  Specifically, this tests for posterior dislocation of the hip. This is part of the standard infant exam performed preferably in early infancy; it usually becomes negative after 2 months of age. It is performed with the Barlow maneuver and inspection of the hip joint and legs.
    (this multiple choice question has been scrambled)
  38. ___ is the presence of extra digits.
    Polydactyly
  39. Polydactyly is ___.

  41. Webbing, or ___, is ___.
    • syndactyly
    • a fusing of the fingers or toes
  42. A patient feels too warm and asks for a fan in her room for her comfort. The nurse enters the room to assess the mother and her infant and finds the infant unwrapped in his crib with the fan blowing over him on “high.” The nurse instructs the mother that the fan should not be directed toward the newborn and the newborn should be wrapped in a blanket. The mother asks why. The nurse’s best response is:

    A. “Your baby may lose heat by conduction, which means that he will lose heat from his body to the cooler ambient air. You should keep him wrapped and prevent cool air from blowing on him.”
    B. “Your baby may lose heat by convection, which means that he will lose heat from his body to the cooler ambient air. You should keep him wrapped and prevent cool air from blowing on him.”
    C. “Your baby will get cold stressed easily and needs to be bundled up at all times.”
    D. “Your baby may lose heat by evaporation, which means that he will lose heat from his body to the cooler ambient air. You should keep him wrapped and prevent cool air from blowing on him.”
    B. “Your baby may lose heat by convection, which means that he will lose heat from his body to the cooler ambient air. You should keep him wrapped and prevent cool air from blowing on him.”
    (this multiple choice question has been scrambled)

    thermogenesis

    Hypothermia from excessive heat loss is a common and dangerous problem in neonates. The newborn infant's ability to produce heat (thermogenesis) often approaches that of the adult; however, the tendency toward rapid heat loss in a cold environment is increased in the newborn and poses a hazard.
