Answer to Question 1

B
The nurse must be able to explain that alcohol and other CNS depressants act on ?-aminobutyric acid
receptors. Because the receptor sites are the same for each of these classes of drugs, cross tolerance
and cross addiction readily occur. Clients need this information to avoid the pitfalls of inappropriate
medication usage. Option A: This system is affected by neuroleptics. Option B: This system is
affected by opioids and synthetic opioids. Option D: This system is affected by selected
antidepressant medication.

Answer to Question 2

ANS:
A, C, E
Rationale: The child can be hypothesized to have moderate to severe trait (chronic) anxiety. A calm
manner will calm the child. A simple, structured, predictable environment is less anxiety provoking
and will reduce overreaction to stimuli. Calm, simple explanations that reinforce reality validate the
environment. Option B: Repetition is often needed when the individual is unable to concentrate
because of elevated levels of anxiety. Option D: Opportunities for play and exercise should be
provided as avenues to reduce anxiety. Physical movement helps channel and lower anxiety. Play
helps by allowing the child to act out concerns.
