Question

Newborns' (neonates') and premature infants' medication needs are different from those of older infants and children, because their

a. kidneys and some endocrine systems are not mature, thus metabolism and excretion are impaired.
b. nervous systems and blood-brain barriers are not mature at birth, thus their nervous systems are more susceptible to the effects of medications.
c. bodies have impaired immune systems, leaving them vulnerable to infections.
d. kidneys, some endocrine systems, nervous systems, and blood-brain barriers are not mature.

Answer 1

The medication needs of newborns' (neonates') and premature infants' are different from those of older infants and children due to the immaturity of their kidneys, some endocrine systems, nervous systems, and blood-brain barriers.

Step-by-step explanation:

The medication needs of newborns' (neonates') and premature infants' are different from those of older infants and children because their kidneys, some endocrine systems, nervous systems, and blood-brain barriers are not mature. These immaturities have various effects on the metabolism, excretion, immune system, and nervous system of newborns, making it necessary to adjust medication dosages and types for newborns. For example, the immature kidneys of neonates can result in impaired metabolism and excretion of medications, necessitating careful consideration of drug doses and administration.
