NR 509 FINAL EXAM QUESTION
WITH VERIFIED ANSWERS
Palmer Grasp Reflex - correct answer-the infant will flex all finger to grasp your finger.
*If seen beyond 4 mo= pyramidal tract dysfunction.
Persistance of a clinched hand over 2 mo=CNS damage *especially if fingers overlap
the thumb.
Plantar grasp reflex - correct answer-6-8 mo Touch the sole at the base of the toes , the
toes will curl. -reflex after 8 months suggest pyramidal tract dysfunction.
Moro reflex (startle reflex) - correct answer-Birth to 4 persistence beyond 4 mo
=cerebral palsy, asymmetric response = fx clavicle, humerus, brachial plexus injury.
Rooting reflexterm-4 - correct answer-3-4 mo. absence- CNS disease
Asymmetric Tonic Neck Reflex - correct answer-Birth- 2 mo infant supine turn head to
one side holding jaw over shoulder the arms/legs on side to which head is turned will
extend while the opposite arm/leg flex. Birth -2 mo. Persistence beyond 2 months
suggest asymmetric central nervous system development/ cerebral palsy
Trunk incurvation (Galant) Reflex - correct answer-Support the infant prone with one
hand and stroke one side of the back 1 cm from midline from shoulder to buttocks. The
spine will curve toward stimulated side.
Absence: transverse spinal cord lesion or injury, persistence may indicate delayed
development.
Landau Reflex - correct answer-Birth- 6 mo suspend infant prone with one hand the
head will flip up and the spine will straighten.
Persistence may indicate delayed development
Parachute Reflex - correct answer-8 mo. does not disappear. Prone lower head toward
surface arms and legs will extend in a protective fashion. Delay in appearance- future
delays in voluntary motor development.
Positive support reflex - correct answer-Birth or 2 mo - 6 mo Hold the infant around the
trunk and lower until the feet touch a flat surface the hips and knees with extend infant
will stand up and partially bear weight. Lack of reflex suggests hypotonia or flaccidity,
fixed extension and adduction of the legs (scissoring) suggest spasticity from neurologic
disease (cerebral palsy)
