Answer to Question 1

ANS: B
The blood-brain barrier is not fully developed at birth. Therefore infants are much more sensitive to central nervous system drugs than are children and older adults.

Answer to Question 2

ANS: C
Physical dependence would require the dose to be decreased and eventually tapered off to prevent an abstinence syndrome, which is specific to physical withdrawal.
A dose increase would be contraindicated, because it may make the patient more dependent and is consistent with drug tolerance.
There is no indication that the patient should be monitored for signs and symptoms of tolerance, which is different from physical dependence.
The central nervous system drug would not be augmented with another drug, because this indicates an addition to the drug regimen, not a replacement.
