multiple choice
1. which is a judgement about a particular patient‘s potential need or problem?
a. a goal
b. an assessment
c. subjective data
d. a nursing diagnosis
answer:- d
nursing diagnosis is the phase of the nursing process during which a clinical judgement is made about how a patient responds to hea
rf
th conditions and life processes or vulnerability for that response.
dif: cognitive level: knowledge
2. the patient is to receive oral furosemide (lasix) every day; however, because the patient is unable to swallow, he cannot take
medication orally, as ordered. the nurse needs to contact the physician. what type of problem is this?
a. a —right time‖ problem
b. a —right dose‖ problem
c. a —right route‖ problem
d. a —right medication‖ problem
answer:- c
this is a —right route‖ problem: the nurse cannot assume the route and must clarify the route with the prescriber. this is not a —right ti me‖
problem because the ordered frequency has not changed. this is not a —right dose‖ problem because the dose is not related to an
inability to swallow. this is not a —right medication‖ problem because the medication ordered will not change, just the route.
dif: cognitive level: application
3. the nurse has been monitoring the patient‘s progress on his new drug regimen since the first dose and has been documenting signs o
f possible adverse effects. what nursing process phase is the nurse practising?
a. planning
b. evaluation
c. implementation
d. nursing diagnosis
rf
answer:- b
monitoring the patient‘s progress is part of the evaluation phase. planning, implementation, and nursing diagnosis are not illustrated
by this example.
dif: cognitive level: application
4. the nurse is caring for a patient who has been newly diagnosed with type 1 diabetes mellitus. which statement best illustrates an o
utcome criterion for this patient?
a. the patient will follow instructions.
b. the patient will not experience complications.
c. the patient adheres to the new insulin treatment regimen.
d. the patient demonstrates safe insulin self-administration technique.
answer:- d
having the patient demonstrate safe insulin self-
administration technique is a specific and measurable outcome criterion. following instructions and avoiding complications are not s
pecific criteria. adherence to the new insulin treatment regimen is not objective and would be difficult to measure.
dif: cognitive level: application
5. which activity best reflects the implementation phase of the nursing process for the patient who is newly diagnosed with type 1 d
iabetes mellitus?
a. providing education regarding self-injection technique
b. setting goals and outcome criteria with the patient‘s input
c. recording a history of over-the-counter medications used at home
d. formulating nursing diagnoses regarding knowledge deficits related to the new t
reatment regimen
answer:- a
education is an intervention that occurs during the implementation phase. setting goals and outcome criteria reflects the planning ph
rf rf
ase. recording a drug history reflects the assessment phase. formulating nursing diagnoses regarding a knowledge deficit reflects a
nalysis of data as part of the planning phase.

multiple choice
1. a patient is receiving two different drugs, which, at their current dose forms and dosages, are both absorbed into the circulation in i
rf
dentical amounts. which term best denotes that the drugs have the same absorption rates?
a. equivalent
b. synergistic
c. compatible
d. bioequivalent
answer:- d
two drugs absorbed into the circulation at the same amount (in specific dosage forms) have the same bioavailability; thus, they are bi
rf
oequivalent. —equivalent‖ is incorrect because the term —bioavailability‖ is used to express the extent of drug absorption. —synergisti c‖
is incorrect because this term refers to two drugs given together whose resulting effect is greater than the sum of the effects of eac
h drug given alone. —compatible‖ is incorrect because this term is a general term used to indicate that two substances do not have a c
rf
hemical reaction when mixed (or given, in the case of drugs) together.
dif: cognitive level: comprehension
2. a patient is receiving medication via intravenous injection. which information should the nurse provide for patient education?
a. the medication will cause fewer adverse effects when given intravenously.
b. the medication will be absorbed slowly into the tissues over time.
c. the medication‘s action will begin faster when given intravenously.
d. most of the drug is inactivated by the liver before it reaches the target area.
answer:- c
intravenous injections are the fastest route of absorption. the intravenous route does not affect the number of adverse effects, the intr
avenous route is not a slow route of absorption, and the intravenous route does not cause inactivation of the drug by the liver before
it reaches the target area.
dif: cognitive level: comprehension
3. which is true regarding parenteral drugs?
a. they bypass the first-pass effect.
b. they decrease blood flow to the stomach.
c. they are altered by the presence of food in the stomach.
d. they exert their effects while circulating in the bloodstream.
answer:- a
drugs given by the parenteral route bypass the first-
pass effect, but they still must be absorbed into cells and tissues before they can exert their effects. enteral drugs (drugs taken orally),
not parenteral drugs, decrease blood flow to the stomach and are altered by the presence of food in the stomach. parenteral drugs mu
st be absorbed into cells and tissues from the circulation before they can exert their effects; they do not exert their effects while circul
rf rf
ating in the bloodstream.
dif: cognitive level: analysis
4. a drug‘s half-life is best defined as
a. the time it takes for the drug to elicit half its therapeutic response.
b. the time it takes one-
half of the original amount of a drug to reach the target cells.
c. the time it takes one-
half of the original amount of a drug to be removed from the body.
d. the time it takes one-
half of the original amount of a drug to be absorbed into the circulation.
answer:- c
a drug‘s half-life is the time it takes for one-
half of the original amount of a drug to be removed from the body. it is a measure of the rate at which drugs are removed from the bo
dy. answers a, b, and d are not correct definitions of a drug‘s half-life.

5. the term —duration of action‖ is best defined as
a. the time it takes for the drug to elicit a therapeutic response.
b. the time it takes a drug to reach its maximum therapeutic response.

c. the length of time it takes to remove a drug from circulation.
rf
d. the time during which drug concentration is sufficient to elicit a therapeutic r

answer:- d
duration of action is the time during which drug concentration is sufficient to elicit a therapeutic response. the time it takes for a dr
ug to elicit a therapeutic response is the drug‘s —onset of action.‖ the time it takes a drug to reach its maximum therapeutic respons
rf rf
e is a drug‘s —peak effect.‖ —the length of time it takes to remove a drug from circulation‖ defines a drug‘s elimination and does not

6. a drug interacts with enzymes by
a. altering cell membrane permeability.
b. —fooling‖ a receptor on the cell wall.
c. enhancing the drug‘s effectiveness within the cells.
d. —fooling‖ the enzyme into binding with it instead of its normal target cell.
answer:- d
when drugs interact with enzymes, they inhibit the action of a specific enzyme by —fooling‖ the enzyme into binding to it instead of
rf rf
to its normal target cell. thus, the target cells are protected from the action of the enzymes to result in a drug effect. the alteration o f
cell membrane permeability, the —fooling‖ of a receptor on the cell wall, and the enhancement of the effectiveness of drugs within c
ells do not occur with selective enzyme interactions.

7. when administering a new medication to a patient, the nurse reads that it is highly protein bound. which consequence will result fr
rf
om this protein binding?
a. renal excretion will take longer.
b. the drug will be metabolized quickly.
c. the duration of action of the medication will be longer.
d. the duration of action of the medication will be shorter.
answer:- c
drugs that are bound to plasma proteins are characterized by a longer duration of action. protein binding does not make renal excreti
rf
on longer and does not increase metabolism of the drug. protein binding of a drug means that the duration of action is longer, not sh
rf rf
orter.

8. when monitoring a patient on an insulin drip to reduce blood glucose levels, the nurse notes that the patient‘s glucose level is e
xtremely low, and the patient is lethargic and difficult to awaken. which adverse drug reaction is the nurse observing?
a. an adverse effect
b. an allergic reaction
c. an idiosyncratic reaction
d. a pharmacological reaction
answer:- d
a pharmacological reaction is an extension of the drug‘s normal effects in the body. in this case, the insulin lowered the patient‘s bl
ood glucose levels too much. an adverse effect is a predictable, well-
known adverse drug reaction that results in minor or no changes in patient management. an allergic reaction (also known as a hyper
sensitivity reaction) involves the patient‘s immune system. an idiosyncratic reaction is unexpected and is defined as a genetically de
termined abnormal response to normal dosages of a drug.

9. a patient is experiencing chest pain and needs to take a sublingual form of nitroglycerin. where should the nurse tell the patient to p
lace the tablet?
a. under the tongue
b. in the space between the cheek and gum
c. at the back of the throat, for easy swallowing
d. on a non-hairy area on the chest
answer:- a
drugs taken by the sublingual route are placed under the tongue. placing the tablet in the space between the cheek and gum is done f
or the buccal route; placing the tablet at the back of the throat (for easy swallowing) is done in the oral route; and placing the tablet on
a non-hairy area on the chest is done in the topical or transdermal route.
dif: cognitive level: comprehension
10. the nurse is administering medications to a patient who is in liver failure due to end-
stage cirrhosis. the nurse is aware that patients with liver failure are most likely to have problems with which pharmacokinet ic
phase?
a. absorption
b. distribution
c. metabolism
d. excretion
answer:- c
the liver is the organ that is most responsible for drug metabolism. decreased liver function will most affect a drug‘s metabolism. t he
rf rf
absorption of a drug is not affected by liver function, and distribution is not affected by liver function. excretion is affected only
because decreased liver function may not transform drugs into water-
soluble substances for elimination via the kidneys, but this is not the best answer to this question.

6. a drug interacts with enzymes by
a. altering cell membrane permeability.
b. —fooling‖ a receptor on the cell wall.
c. enhancing the drug‘s effectiveness within the cells.
d. —fooling‖ the enzyme into binding with it instead of its normal target cell.
answer:- d
when drugs interact with enzymes, they inhibit the action of a specific enzyme by —fooling‖ the enzyme into binding to it instead of
rf rf
to its normal target cell. thus, the target cells are protected from the action of the enzymes to result in a drug effect. the alteration o f
cell membrane permeability, the —fooling‖ of a receptor on the cell wall, and the enhancement of the effectiveness of drugs within c
ells do not occur with selective enzyme interactions.

7. when administering a new medication to a patient, the nurse reads that it is highly protein bound. which consequence will result fr
rf
om this protein binding?
a. renal excretion will take longer.
b. the drug will be metabolized quickly.
c. the duration of action of the medication will be longer.
d. the duration of action of the medication will be shorter.
answer:- c
drugs that are bound to plasma proteins are characterized by a longer duration of action. protein binding does not make renal excreti
rf
on longer and does not increase metabolism of the drug. protein binding of a drug means that the duration of action is longer, not sh
rf rf
orter.

8. when monitoring a patient on an insulin drip to reduce blood glucose levels, the nurse notes that the patient‘s glucose level is e
xtremely low, and the patient is lethargic and difficult to awaken. which adverse drug reaction is the nurse observing?
a. an adverse effect
b. an allergic reaction
c. an idiosyncratic reaction
d. a pharmacological reaction
answer:- d
a pharmacological reaction is an extension of the drug‘s normal effects in the body. in this case, the insulin lowered the patient‘s bl
ood glucose levels too much. an adverse effect is a predictable, well-
known adverse drug reaction that results in minor or no changes in patient management. an allergic reaction (also known as a hyper
sensitivity reaction) involves the patient‘s immune system. an idiosyncratic reaction is unexpected and is defined as a genetically de
termined abnormal response to normal dosages of a drug.

9. a patient is experiencing chest pain and needs to take a sublingual form of nitroglycerin. where should the nurse tell the patient to p
lace the tablet?
a. under the tongue
b. in the space between the cheek and gum
c. at the back of the throat, for easy swallowing
d. on a non-hairy area on the chest
answer:- a
drugs taken by the sublingual route are placed under the tongue. placing the tablet in the space between the cheek and gum is done f
or the buccal route; placing the tablet at the back of the throat (for easy swallowing) is done in the oral route; and placing the tablet on
a non-hairy area on the chest is done in the topical or transdermal route.

10. the nurse is administering medications to a patient who is in liver failure due to end-
stage cirrhosis. the nurse is aware that patients with liver failure are most likely to have problems with which pharmacokinet ic
phase?
a. absorption
b. distribution
c. metabolism
d. excretion
answer:- c
the liver is the organ that is most responsible for drug metabolism. decreased liver function will most affect a drug‘s metabolism. t he
rf rf
absorption of a drug is not affected by liver function, and distribution is not affected by liver function. excretion is affected only
because decreased liver function may not transform drugs into water-
soluble substances for elimination via the kidneys, but this is not the best answer to this question.
