6. The nurse is working during a very busy night shift, and the health care provider has just given the nurse a medication order o
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
ver the telephone, but the nurse does not recall the route. What is the best way for the nurse to avoid medication errors?
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
a. Recopy the order neatly on the order sheet, with the most common route indicated
#? #? #? #? #? #? #? #? #? #? #? #? #?
b. Consult with the pharmacist for clarification about the most common route
#? #? #? #? #? #? #? #? #? #?
c. Call the health care provider to clarify the route of administration
#? #? #? #? #? #? #? #? #? #?
d. Withhold the drug until the health care provider visits the patient
#? #? #? #? #? #? #? #? #? #?
ANS: C #?
If a medication order does not include the route, the nurse must ask the health care provider to clarify it. Never assume the route of a

d. Right patient, right diagnosis, right drug, right route, and right time
#? #? #? #? #? #? #? #? #? #?
ANS: A #?
The traditional Five Rights of medication administration were considered to be Right drug, Right route, Right dose, Right time, and
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
Right patient. Right effect, right strength, and right diagnosis are not part of the traditional Five Rights.

8. What correctly describes the nursing process?
#? #? #? #? #?
a. Diagnosing, planning, assessing, implementing, and finally evaluating #? #? #? #? #? #?
b. Assessing, then diagnosing, implementing, and ending with evaluating #? #? #? #? #? #? #?
c. A linear direction that begins with assessing and continues through diagnosing

d. An ongoing process that begins with assessing and continues with diagnosing
#? #? #? #? #? #? #? #? #? #?
, planning, implementing, and evaluating
#? #? #? #?
ANS: D #?
The nursing process is an ongoing, flexible, adaptable, and adjustable five-
#? #? #? #? #? #? #? #? #? #?
step process that begins with assessing and continues through diagnosing, planning, implementing, and finally evaluating, which
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
may then lead back to any of the other phases.

9. When the nurse is considering the timing of a drug dose, which is most important to assess?
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
a. The patient’s identification #? #?
b. The patient’s weight #? #?
c. The patient’s last meal #? #? #?
d. Any drug or food allergies #? #? #? #?
ANS: C #?
The pharmacokinetic and pharmacodynamic properties of the drug need to be assessed with regard to any drug–
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
food interactions or compatibility issues. The patient’s identification, weight, and drug or food allergies are not affected by the drug’
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
s timing.

10. The nurse is writing nursing diagnoses for a plan of care. Which reflects the correct format for her nursing diagnosis?
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
a. Anxiety
b. Anxiety related to new drug therapy #? #? #? #? #?
c. Anxiety related to anxious feelings about drug therapy, as evidenced b

d. Anxiety related to new drug therapy, as evidenced by statements such as “I’
#? #? #? #? #? #? #? #? #? #? #? #?
m upset about having to give myself shots”
#? #? #? #? #? #? #?
ANS: D #?
Formulation of nursing diagnoses is usually a three- #? #? #? #? #? #? #?
step process. The only complete answer is “Anxiety related to new drug therapy, as evidenced by statements such as ‘I’m upset
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
about having to give myself shots.’” The answer “Anxiety” is missing the “related to” and “as evidenced by” portions. The ans
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
wer “Anxiety related to new drug therapy” is missing the “as evidenced by” portion of defining characteristics. The “related to”
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
section in “Anxiety related to anxious feelings about drug therapy, as evidenced by statements such as ‘I’m upset about having t
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
o give myself shots’” is simply a restatement of the problem “anxiety,” not a separate factor related to the response.

a. Equivalent
b. Synergistic
c. Compatible
d. Bioequivalent
ANS: D #?
Two drugs absorbed into the circulation at the same amount (in specific dosage forms) have the same bioavailability; thus, they a

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.

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.
#? #? #? #? #? #? #? #?
ANS: 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 or
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?

ver the telephone, but the nurse does not recall the route. What is the best way for the nurse to avoid medication errors?
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?
a. Recopy the order neatly on the order sheet, with the most common route indicated
#? #? #? #? #? #? #? #? #? #? #? #? #?
b. Consult with the pharmacist for clarification about the most common route
#? #? #? #? #? #? #? #? #? #?
c. Call the health care provider to clarify the route of administration

d. Withhold the drug until the health care provider visits the patient
#? #? #? #? #? #? #? #? #? #?
ANS: C #?
If a medication order does not include the route, the nurse must ask the health care provider to clarify it. Never assume the route of a

MULTIPLE CHOICE #?
1. A patient is receiving two different drugs, which, at their current dose forms and dosages, are both absorbed into the circulation
#? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #? #?

#? #? #? #? #? #? #? #? #? #? #? #? #? #?
a. Equivalent
b. Synergistic
c. Compatible
d. Bioequivalent
ANS: D #?
Two drugs absorbed into the circulation at the same amount (in specific dosage forms) have the same bioavailability; thus, they a

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.
#? #? #? #? #? #? #? #? #? #? #? #? #? #?

#? #? #? #? #? #? #? #?
ANS: 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 or
