Answer to Question 1

ANS: A
The brain is involved in mental activity, maintenance of homeostasis, and control of all
physiological functions. Brain neuronal activity involves conducting electrical impulses from one
end of the cell to the other, involving inward movement of sodium followed by outward movement
of potassium. Without sufficient sodium and potassium, electrical conduction of impulses is
impaired. Physical and mental symptoms result.

Answer to Question 2

C
Staying with a distraught client who is hearing voices serves several purposes: ongoing observation,
the opportunity to provide reality orientation, a means of helping dismiss the voices, the opportunity
of forestalling an action that would result in self-injury, and general support to reduce anxiety.
Option A is not particularly relevant at this point. Option B is relevant for assessment purposes but
is less helpful than option C. Option D shifts responsibility for intervention from the nurse to the
client and other clients.
