FINALS - Reflexes Flashcards
What is the rooting reflex?
Stimulus: Stroking the baby’s cheek.
Response: Turns head and opens mouth toward the stimulus.
What is the sucking reflex?
Stimulus: Placing an object (like a finger or nipple) in the baby’s mouth.
Response: Sucks rhythmically.
What is the Moro reflex?
Stimulus: Sudden movement, loud sound, or dropping sensation.
Response: Extends arms, spreads fingers, then retracts arms and cries.
What is the palmar grasp reflex?
Stimulus: Placing a finger or object in the baby’s palm.
Response: Grasps the object firmly.
What is the plantar grasp reflex?
Stimulus: Pressing a finger against the sole of the baby’s foot.
Response: Toes curl down.
What is the Babinski reflex?
Stimulus: Stroking the sole of the foot from heel to toes.
Response: Toes fan out and the big toe dorsiflexes.
What is the tonic neck reflex?
Stimulus: Turning the baby’s head to one side.
Response: Arm on the same side extends, opposite arm flexes.
What is the stepping reflex?
Stimulus: Holding the baby upright with feet touching a surface.
Response: Mimics stepping movements.
What is the Galant reflex?
Stimulus: Stroking one side of the baby’s spine while holding them face down.
Response: Curves body toward the stimulated side.
What stimulus elicits the rooting reflex in a newborn?
A. Stroking the cheek
Rationale: The rooting reflex is triggered when the baby’s cheek is stroked, causing them to turn their head and open their mouth toward the stimulus.
Which reflex involves the newborn turning their head and extending the arm on the same side?
B. Tonic neck reflex
Rationale: The tonic neck reflex, also called the fencing reflex, occurs when the baby’s head is turned, causing the arm on the same side to extend while the opposite arm flexes.
What response is expected when the baby’s palm is stimulated?
B. Grasp the object firmly
Rationale: The palmar grasp reflex is demonstrated when a baby firmly grasps an object placed in their palm.
What is the expected response in the Babinski reflex?
C. Toes fan out and the big toe dorsiflexes
Rationale: The Babinski reflex involves fanning of the toes and dorsiflexion of the big toe when the sole is stroked.
Which reflex disappears as the infant begins voluntary walking?
C. Stepping reflex
Rationale: The stepping reflex, where the baby mimics walking movements when held upright, disappears as they begin voluntary walking.
Which stimulus triggers the Moro reflex?
B. Sudden movement or loud noise
Rationale: The Moro reflex, or startle reflex, is triggered by a sudden movement, loud sound, or the sensation of being dropped.
What is the response to stroking one side of the baby’s spine in the Galant reflex?
C. Curving the body toward the stimulus
Rationale: In the Galant reflex, the baby curves their body toward the side being stroked.
What action demonstrates the plantar grasp reflex?
B. Curling of the toes downward
Rationale: The plantar grasp reflex is observed when the toes curl downward in response to pressure on the sole of the foot.
Which reflex is vital for feeding in a newborn?
B. Rooting reflex
Rationale: The rooting reflex helps the baby locate the nipple for feeding by turning toward the cheek stimulus.
When placing an object in a newborn’s mouth, what reflex is observed?
B. Sucking reflex
Rationale: The sucking reflex is seen when a baby rhythmically sucks on an object placed in their mouth.
At what age does the Moro reflex typically disappear?
B. 4–6 months
Rationale: The Moro reflex usually fades by 4–6 months as the baby develops more controlled movements.
What response is expected when the baby’s head is turned to one side in the tonic neck reflex?
B. Arm and leg on the same side extend
Rationale: In the tonic neck reflex, turning the baby’s head results in extension of the arm and leg on the same side.
What reflex involves spreading and retracting the arms after a loud noise?
B. Moro reflex
Rationale: The Moro reflex, or startle reflex, is characterized by the baby extending and retracting the arms in response to a loud noise.
Which reflex is also known as the fencing reflex?
B. Tonic neck reflex
Rationale: The tonic neck reflex is nicknamed the fencing reflex due to the arm positioning resembling a fencer’s stance.
What reflex helps babies prepare for voluntary walking?
B. Stepping reflex
Rationale: The stepping reflex mimics walking movements, aiding neuromuscular development for voluntary walking.
What is the typical response in the palmar grasp reflex?
B. Baby grasps an object placed in the palm
Rationale: The palmar grasp reflex is activated when an object is placed in the baby’s palm, leading to a firm grasp.
What does the Galant reflex help indicate in newborns?
A. Neuromuscular development of the spine
Rationale: The Galant reflex assesses neuromuscular function and spinal development in newborns.
What is the appropriate response to a Babinski reflex test in a newborn?
B. Big toe dorsiflexes and other toes fan out
Rationale: The Babinski reflex in newborns demonstrates a dorsiflexed big toe and fanning of the other toes.
Which reflex is considered an indicator of neurological health in newborns?
D. All of the above
Rationale: Reflexes like Moro, rooting, and sucking are vital indicators of a newborn’s neurological development and function.
At what age does the rooting reflex typically disappear?
B. 4–6 months
Rationale: The rooting reflex fades as the baby begins to develop more voluntary head and neck control by 4–6 months.
What reflex involves a rhythmic sucking motion?
B. Sucking reflex
Rationale: The sucking reflex ensures that newborns can feed effectively when an object is placed in their mouth.
Which reflex is elicited by placing pressure on the sole of the foot?
B. Plantar grasp reflex
Rationale: The plantar grasp reflex is observed when the toes curl downward in response to pressure on the sole.
How is the stepping reflex tested?
B. Holding the baby upright with feet touching a surface
Rationale: The stepping reflex mimics walking motions when the baby’s feet touch a flat surface while being held upright.
Which reflex helps the baby locate the source of food?
B. Rooting reflex
Rationale: The rooting reflex assists the baby in locating the source of food by turning their head toward the stimulus.
What is a typical response during the Moro reflex?
C. Arms extend and retract with crying
Rationale: The Moro reflex involves extending the arms, spreading the fingers, then retracting the arms with or without crying.
What reflex is observed when a newborn’s spine is stroked?
C. Galant reflex
Rationale: The Galant reflex causes the baby’s body to curve toward the side of the spine being stroked.
What is the purpose of the Moro reflex in evolutionary terms?
B. Protection from danger
Rationale: The Moro reflex is thought to be an evolutionary response that protects the infant by reacting to perceived threats.
What is the expected response in a tonic neck reflex?
B. Arm on the same side extends while the opposite arm flexes
Rationale: The tonic neck reflex results in a fencing posture where the arm on the side the head is turned extends.
What reflex typically appears at birth and disappears by 2–4 months?
D. All of the above
Rationale: Reflexes like Galant, rooting, and Moro appear at birth and fade as voluntary motor control develops.
Which reflex is tested by stroking the cheek of a newborn?
B. Rooting reflex
Rationale: Stroking the cheek triggers the rooting reflex, which helps the newborn locate a source of food.
