Complete Solutions
A client has a long history of hypertension. The healthcare

the nurse?
Choose all that apply
A.
"Newer drugs are altered to affect your cells' receptors in a
different way."
B.
"Receptors tend to 'burn-out,' so newer drugs are required."
C.
"Research into receptors helps 'fine-tune' drugs to be more
effective."
D.
"Changing the response of the drug to protein receptor-
complexes produces fewer side effects."
E.
"It is a process of trial and error with receptors until the new
drug proves effective." Correct Answers A.
"Newer drugs are altered to affect your cells' receptors in a
different way."
C.
"Research into receptors helps 'fine-tune' drugs to be more
effective."
,A client looks up the drug they are taking in a drug guide. The
client asks a nurse why the healthcare provider prescribed a
medication that has a lethal dose measure. What is the best
response by the nurse?
A.

determine the safe dose to give."
B.
"Don't worry about that, I'll have your healthcare provider

given could be lethal. Correct Answers 2
A nurse explains to a student nurse that pharmacogenetics is a
relatively new area within pharmacology. Which statement best
describes the potential of this new area?
A.
To reduce the overall number of drugs and their associated
adverse effects
B.
To reduce medication errors and provide optimal drug choices
C.
