Which newborn reflex is elicited by stroking the lateral sole of the infant's foot from the heel to the ball of the foot?
a. Babinski
b. Tonic neck
c. Stepping
d. Plantar grasp
A
The Babinski reflex causes the toes to flare outward and the big toe to dorsiflex.
The tonic neck reflex (also called the fencing reflex) refers to the posture assumed by new-borns when in a supine position.
The stepping reflex occurs when infants are held upright with their heel touching a solid sur-face and the infant appears to be walking.
Plantar grasp reflex is similar to the palmar grasp reflex: when the area below the toes is touched, the infant's toes curl over the nurse's finger.

A patient presents at the walk-in clinic complaining of stomach pain that is relieved by eating which the nurse suspects is caused by a peptic ulcer. How would the nurse explain the ulceration in the stomach to the patient?
A) A mucosal lining protects the stomach from hydrochloric acid and a reduction in the mucosal lining or increase in acid production allows peptic ulcers to develop. B) After digesting food, the stomach secretes a neutralizing solution to make the pH of the stomach neutral and if this doesn't occur peptic ulcers can develop. C) Our body makes hydrochloric acid for the digestion of the food we eat and that can eat right through the stomach causing ulceration when you eat a diet high in spicy food. D) Acid is secreted by cells in the first part of the small intestine and when we eat the acid flows into the stomach so people who eat often have more exposure to acid.
