Maternity Nursing Q 3

---

A newborn who has an asymmetrical Moro reflex response should be further assessed for which of the following?

  

     A. Talipes equinovarus

     B. Fractured clavicle

     C. Congenital hypothyroidism

     D. Increased intracranial pressure

    

    

Correct Answer: B. Fractured clavicle

---

A fractured clavicle would prevent the normal Moro response of symmetrical sequential extension and abduction of the arms followed by flexion and adduction.

---

Option A: In talipes equinovarus (clubfoot) the foot is turned medially, and in plantar flexion, with the heel elevated. The feet are not involved with the Moro reflex.

Option C: Hypothyroidism has no effect on the primitive reflexes. Hypothyroidism means that the thyroid gland can’t make enough thyroid hormones to keep the body running normally.

Option D: The absence of the Moro reflex is the most significant single indicator of central nervous system status, but it is not a sign of increased intracranial pressure.
