The nurse understands that the dose-response relationship is graded and should expect to observe
what response?
Once a drug is given, the response is predictably all-or-nothing.
The response is maintained at a specific level when the therapeutic objective is achieved.
As the dosage increases, the response becomes progressively greater.
A graded response is based on relative potency and maximal efficacy. - Answer>>> As the
dosage increases, the response becomes progressively greater.
Which statement by the nursing student indicates a need for further instruction about drug
selectivity?
"Botulinum toxin is very selective and therefore very safe for administration."
"Selective drug action is made possible by many types of receptors in the body."
"The more selective a drug is, the fewer side effects it will produce."
"Even though a drug is selective, it can produce nonselective results." - Answer>>> Botulinum
toxin is very selective and therefore very safe for administration

When studying the effects of drugs in humans, the nurse is learning about what?

Clinical pharmacology
Therapeutics
Effectiveness - Answer>>> Clinical pharmacology

, A nursing student is caring for a patient who has been taking morphine sulfate for pain for 2
weeks. The nursing student shows an understanding of pharmacodynamic tolerance by
describing it to the instructor in what way?
"It is a form of tolerance that is a reduction in drug responsiveness brought on by repeated
dosing over a short period."
"It affects the minimum effective concentration."
"It is a drug response caused by psychologic factors, not by biochemical or physiological
properties."
"It is a condition in which the patient requires increased doses of morphine sulfate to achieve
pain relief." - Answer>>> "It is a condition in which the patient requires increased doses of
morphine sulfate to achieve pain relief."
Which statement by a new nurse indicates that further study is indicated?

The nurse administers 100 mg of drug X by mouth. After the drug moves through the hepatic
