Answer to Question 1

Ans: B
Myelinization occurs in a cephalocaudal, proximodistal manner and is completed by 2 years of age. As myelinization proceeds, nerve impulses become faster and more accurate.

Answer to Question 2

Ans: A
Subcutaneous (SQ) administration distributes medication into the fatty layers of the body. It is used primarily for insulin administration, heparin, and certain immunizations, such as MMR. Intradermal administration is used primarily for tuberculosis screening and allergy testing. Intramuscular administration is used to administer certain medications, such as many immunizations. Insulin is not administered orally.
