Which of the following statements should the nurse include in the teaching? (Select all that apply.)

“The Moro reflex is also called the startle reflex because it occurs when the baby is startled by something.”

“The Moro reflex helps the baby develop their sense of balance and coordination.”

“The Moro reflex involves extending and flexing the arms and legs in response to a sudden movement.”

“The Moro reflex can be used to assess the integrity of the baby’s nervous system.”

“The Moro reflex can be triggered by changing the baby’s position or temperature.”

Answer and Explanation

Correct Answer : A,C,D

The Moro reflex, or startle reflex, is an involuntary response to a sudden loss of support or a loud noise that involves spreading and curling the arms and legs.

The Moro reflex involves three distinct components: spreading out the arms (abduction), pulling the arms in (adduction), and crying (usually). The baby may also extend and flex their legs.

The Moro reflex can be used to assess the integrity of the baby’s nervous system, as it reflects the development and function of the brain stem. Absence, asymmetry, or persistence of the Moro reflex may indicate neurological problems.
