Answer to Question 1

A
Feedback:
At the acetylcholine receptor site on the effector's side of the synapse, the acetylcholine interacts with the nicotinic cholinergic receptors causing the depolarization. Serotonin, GAMA, and epinephrine are not part of muscle contraction and relaxation.

Answer to Question 2

D
Feedback:
Normal reactions to immunizations include pain, redness, and swelling at the site of the injection. Vomiting, diarrhea, high fever, sweating, lethargy, or drowsiness would not be expected and should be reported. The child could also be slightly irritable due to the pain at the injection site.
