During a routine assessment of an 8-month-old, the nurse is assessing primitive reflexes. Which finding should the nurse expect for an infant of this age?
When hearing a loud noise, the infant cries and extends both arms and legs.
When stroking the outer edge of the sole of the infant's foot, the toes fan upward and out.
When infant's head is turned to one side, extension of the same side arm and leg occurs.
When stroking the cheek, the infant turns toward that side of stimulation.
The Correct Answer is B
A. The Moro reflex, where the infant cries and extends both arms and legs in response to a loud noise, typically disappears by 4-6 months of age and would not be expected at 8 months.
B. The Babinski reflex, where the toes fan upward and out when the outer edge of the sole is stroked, is normal in infants and usually disappears by 12-24 months of age.
C. The tonic neck reflex (fencing reflex) typically disappears around 4-6 months of age, so it would not be expected in an 8-month-old.
D. The rooting reflex, where the infant turns their head toward the side of stimulation when the cheek is stroked, typically disappears by 3-4 months of age.
