A new mother shows the nurse that her baby grasps her finger when she touches the baby's palm. How might the nurse respond to this information?

A. "This is a primitive reflex known as the palmar grasp.": The palmar grasp reflex is a primitive reflex observed in newborns where they automatically grasp onto objects (or fingers) that touch

their palms. This reflex typically disappears by around 6 months of age.

B. "This is a protective reflex known as rooting.": Rooting is a reflex where newborns turn their head and open their mouth in response to cheek or mouth stimulation, facilitating breastfeeding. It is not related to grasping objects with the hands.

C. "This is a primitive reflex known as the plantar grasp.": The plantar grasp reflex is similar to the palmar grasp but occurs when pressure is applied to the sole of the foot. It is unrelated to grasping objects with the hands.

D. "This is a protective reflex known as the Moro reflex.": The Moro reflex, also known as the startle reflex, involves the newborn's arms and legs extending and then flexing in response to a sudden movement or loud noise. It is not related to grasping objects with the hands.

A. At the beginning: It is not necessary to examine the tympanic membrane at the very beginning of the physical examination.

B. Before auscultating the chest and abdomen: While the tympanic membrane examination may precede auscultation of the chest and abdomen, it is not typically performed before all other components of the physical examination.

C. Before examining the head and neck: Examination of the tympanic membrane is usually part of the head and neck assessment, so it would not occur before examining these areas.

D. At the enD. Examination of the tympanic membrane is typically performed towards the end of the physical examination, after other components such as inspection, palpation, and auscultation have been completed. This sequence allows the nurse to maintain the flow of the examination and ensures a thorough assessment of all body systems.
