Answer to Question 1

A
Feedback:
Oxytocin and mild stress act to increase actual learning. Childbirth is the only time that oxytocin levels increase and this phenomenon is not clearly understood. Acetylcholine, serotonin, and dopamine do not increase actual learning; they function as neurotransmitters.

Answer to Question 2

C
Feedback:
The nurse will administer 100 mg rectally. The other doses are inappropriate. A usual dose of palonosetron for an adult is 0.25 mg IV. A usual dose of hydroxyzine for a child is 1.1 mg/kg IM, and a usual dose of trimethobenzamide for a child weighing more than 30 pounds is 200 mg orally.

This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
