Question 1
Drug action is affected by many factors. All of the following affect drug action
EXCEPT:
A. The patient's intelligence
B. The size and age of the patient
C. Other drugs the resident is taking
D. Time and route of administration
VERIFIED ANSWER A. The patient's intelligence
Rationale: Drug action depends on numerous physiological and
pharmacological factors, such as age-related metabolism, concurrent
medications, and the timing or method (route) of administration. A patient's
intelligence level does not directly affect how a drug is absorbed, distributed,
metabolized, or excreted. In contrast, factors such as body size, organ
function, and drug interactions have a profound impact on a medication's
effectiveness and safety .
Question 2
Which abbreviations are most likely to be found on an order for eye
medication?
A. IM, IV, SQ
B. Stat, n.p.o., h.s.
C. bid, qid, tid, qod
D. OD, OU, OS, ophth.
VERIFIED ANSWER D. OD, OU, OS, ophth.
Rationale: OD (oculus dexter) = right eye, OS (oculus sinister) = left eye, OU
,(oculus uterque) = both eyes. "ophth." is shorthand for ophthalmic, pertaining
to the eye. The other abbreviations (IM – intramuscular, IV – intravenous, etc.)
are not meant for eye-specific orders .
Question 3
The drug name owned by the manufacturer is called the:
A. Brand name
B. Product name
C. Trade name
D. All of the above
VERIFIED ANSWER D. All of the above
Rationale: "Brand name," "trade name," and "product name" are often used
interchangeably to describe the proprietary name a manufacturer gives to a
drug. This name is distinct from the generic or chemical name, which does not
belong exclusively to any one company .
Question 4
Pharmacokinetics is the study of:
A. The study of prescription drugs only
B. The signs and symptoms of disease
C. The absorption, distribution, metabolism, and excretion of drugs
D. None of the above
VERIFIED ANSWER C. The absorption, distribution, metabolism, and excretion
of drugs
Rationale: Pharmacokinetics (often remembered by the acronym ADME)
focuses on how the body handles a drug: how it is absorbed, how it travels
(distributed), how it is chemically altered (metabolized), and how it is
,eliminated (excreted). This is different from pharmacodynamics, which studies
the drug's effects on the body .
Question 5
Examples of drugs made from animal sources are:
A. Insulin and heparin
B. Furosemide and castor oil
C. Magnesium hydrochloride and iodine
D. Iron and calcium
VERIFIED ANSWER A. Insulin and heparin
Rationale: Some medications are derived from animal substances: insulin
(commonly from pork or recombinant DNA sources) and heparin (traditionally
sourced from animal tissues). The other examples (like furosemide, iron
supplements, or castor oil) come from different sources (synthetic, mineral, or
plant) .
Question 6
A patient may take two drugs for hypertension because of their:
A. Antagonistic effect
B. Potentiation
C. Synergistic effect
D. Idiosyncratic response
VERIFIED ANSWER C. Synergistic effect
Rationale: A synergistic effect occurs when two drugs taken together produce
a combined effect greater than the sum of their separate effects. In
hypertension, combination therapy that has a synergistic effect may improve
blood pressure control .
, Question 7
Pharmacodynamics is the study of:
A. Drug sources
B. The medical field
C. The diseases of the body
D. The interactions between drugs and the body
VERIFIED ANSWER D. The interactions between drugs and the body
Rationale: Pharmacodynamics examines how a drug exerts its effect on the
body, including the mechanism of action and the relationship between drug
concentration and effect. It differs from pharmacokinetics, which deals with
how the body processes the drug .
Question 8
The following abbreviations are correct EXCEPT:
A. b.i.d. means 2 times daily
B. n.p.o. means nothing by mouth
C. stat means now
D. q.i.d. means every other day
VERIFIED ANSWER D. q.i.d. means every other day
Rationale: q.i.d. (quater in die) actually means "four times a day." "Every other
day" is typically written as "q.o.d." or "qod" but is recommended to be spelled
out to avoid confusion .
Question 9
Rules that ensure uniform strength, quality, and purity of drugs are called:
A. Drug standards
B. Drug references
C. Drug laws
