A nurse administers drug A to a patient. The nurse understands that the more types of receptors there are for the drug to work with, the greater the chance of producing which effect in the patient?
a. Toxic levels
b. Subtherapeutic levels
c. Selective drug effects
d. Minimal drug effects
ANS: C
Selective drug effects are elicited when more types of receptors are available for the drug to work with.
Toxic levels would more likely be produced by too much of a drug, not by the greater number of receptors available for the drug to work with.
Subtherapeutic levels are related to the presence of a smaller amount of the drug or to fewer doses of the drug rather than more types of receptors available for the drug to work with.
Minimal drug effects would be below the minimal concentration and therefore the same as subtherapeutic effects.
