A nurse is explaining to parents how the central nervous system of a child differs from that of an adult. Which statement accurately describes these differences?
 
  a. The infant has 150 milliliters of cerebrospinal fluid compared with 50 milliliters in the adult.
  b. Papilledema is a common manifestation of increased intracranial pressure in the very young child.
  c. The brain of a term infant weighs less than half of the weight of the adult brain.
  d. Coordination and fine motor skills develop as myelinization of peripheral nerves progresses.

Question 2

A nurse is preparing to administer 10 units of Regular insulin and 5 units of Lente insulin. Place in order the steps the nurse should follow to administer the total dosage of 15 units of insulin.
 
  Place the initial step first and end with the final step. Use the following format for your Answer: A, B, C, D a. Inject 5 units of air into the Lente insulin vial.
  b. Draw up the 5 units of Lente insulin.
  c. Inject 10 units of air into the Regular insulin vial.
  d. Cleanse the insulin vials with alcohol wipes.
  e. Draw up the 10 units of Regular insulin.

Answer to Question 1

D
Peripheral nerves are not completely myelinated at birth. As myelinization progresses, so does the child's coordination and fine muscle movements. An infant has about 50 milliliters of cerebrospinal fluid compared with 150 milliliters in an adult. Papilledema rarely occurs in infancy because open fontanels and sutures can expand in the presence of increased intracranial pressure. The brain of the term infant is two-thirds the weight of an adult's brain.

Answer to Question 2

D, A, C, E, B

Cleanse the insulin vials with alcohol wipes initially. When mixing two different types of insulin, inject the appropriate amount of air into both vials and then withdraw the short-acting (clear) insulin first. So the steps should be to cleanse the insulin vials, inject air into the Lente, inject air into the Regular insulin vial, then draw the Regular (clear) insulin, and lastly draw the Lente (cloudy) insulin.
