• The name selected by the original manufacturer based on
the chemical structure of the drug is the:
A. Chemical name
B.Drug name
C.Generic name
D. Trade name
Rationale: Generic name is the identification of the drug as
named by the manufacturer basing from the chemical
structure of the drug, while chemical name is for the
chemical structure of the compound. And lastly the trade
name comes from the company who produces the drug.
• The interaction of one drug increased by the presence of a
second drug is known as:
A. Potentiation
B.Addictive effects
C.Antagonist
D. Synergism
Rationale: One of the drug to drug interactions is the
potentiation, this is answer is to be considered among the
rest because by definition, one drug potentiates the other, in
other words the effectiveness of one drug is being increased
once combined with another.
• When two drugs given together have an effect equal to the
sum of their respective effects, the interaction is known as:
A. Potentiated
B.Antagonized
C.Agonist
D. Additive
,2
Rationale: From the root word itself, “Add”, by definition
once two drug is being administered the effectiveness is the
sum of their respective effects.
• When a drug is 50% protein bound, it means that:
A. 50% of the drug destroys protein
B. 50% of the dose is at work
C.50% of the drug is excreted in the kidneys
D. Protein must be restricted in the diet
Rationale: There are many metabolic activities within the
body that uses protein as a resource of a process, however
answers A,C, and D does not represent any of these actions
done by a 50% protein bound drug. What it does mean is
that 50% is of the dose is at work.
• Safety of a drug is determined by the degree between:
A. Therapeutic and toxic doses
B.Potency and efficacy
C.Subtherapeutic and toxic levels
D. Side and adverse effects
Rationale: Among the rest of the choices what mostly speaks
about the safety of the drug is therapeutic and toxic doses,
potency and efficicacy do not speaks about safety same with
side and adverse effects which are part of the drug’s
responses in the body. .
• When a drug binds to a receptor to produce a pharmacologic
effect, the drug may be called a(n):
A. Agonist
B.Antagonist
C.Blocker
D. Accelerator
Rationale: The action of a drug that binds or connect itself in
a receptor to stimulate a biological response is called
Agonist.
• Distribution is affected by:
, 3
A. Biotransformation
B.Excretion
C.Protein binding
D. Lipid binding
Rationale: The answer is protein binding because it is the
way or manner how drug is being distributed in the body,
while the other two processes, biotransformation and
excretion do not affect drug distribution.
• An unexpected effect of the drug is known as a(n):
A. Side effect
B. Adverse effect
C.Toxic reaction
D. Allergic reaction
Rationale: Side effects are known reaction of the drugs while
adverse effects are undesirable and unpredictable reactions
of a drug.
• When performing an assessment about medication, the drug
history should include:
A. Complete vital signs
B.Client’s goal of therapy
C.Reason for medication
D. Administration of OTC medications
Rationale: Choice D is the most accurate because it is needed
in the assessment to inform the client if she is currently
under OTC medications that their effects are going to be
minimized.
• The volume of SC medication must be no more than:
A. 0.5 mL
B. 1.0 mL
C.1.5 mL
D. 3.0 mL
