ABRAMS CLINICAL DRUG THERAPY
RATIONALES FOR NURSING PRACTICE EXAM
PREPARATION PACK 2026 KEY CONCEPTS
AND REVISION NOTES
◉ 1.2 Error-reduction strategies during medication administration
include which of the following? (Select all that apply.)
A. quiet zone signs at entrance to the medication room
B. protocols and checklist outlining medication administration
C. wearing of a sash or vest to signal others to avoid interruptions of
the nurse during medication administration
D. carrying several patients' prescanned medications on a tray.
Answer: A, B, and C.
Rationale: All of these strategies, except for carrying several clients'
prescanned medications on a cart, potentially reduce the risk of
medication error. The work-around of removing more than one
client's medication from an automated medication dispensing
system could lead to the administration of the wrong medication to
a client.
◉ 2.1 A nurse practitioner (NP) has just changed a patient's
medication from an oral form to a patch formulation to avoid the
first-pass effect. The NP has explained it to the patient, but the
patient still has questions and asks the nurse to explain again what
,is meant by the first-pass effect. The nurse would be most correct in
explaining that this has to do with how
A. drugs initially bind to plasma proteins
B. initial renal function is involved in drug excretion
C. the way drugs first reach their target cells
D. initial metabolism of an oral drug occurs before it reaches the
systemic circulation.
Answer: D.
Rationale: The "first-pass effect" involves metabolism of an oral drug
in the liver so that only a portion of a drug dose reaches the systemic
circulation and becomes available to act on target tissues or to be
eliminated from the body. Drug binding to plasma proteins affects
drug distribution; an increased amount of drug has to be absorbed
before effective therapeutic levels of unbound drug are reached.
◉ 2.2 A nurse is reading a research report about use of a medication
that describes the pharmacokinetics of a particular medication that
a patient is taking. Pharmacokinetics involves
A. drug effects on human cells
B. drug binding with receptors
C. drug absorption, distribution, metabolism, and elimination
D. drug stimulation of normal cell functions.
Answer: C.
,Rationale: Pharmacokinetics involves movement of a drug through
the body and its elimination. Drug binding with receptors and drug
effects on cells are pharmacodynamic processes. Drug stimulation of
normal cell functions describes an agonist drug.
◉ 2.3 A nurse is caring for a man who has worsening liver disease.
In monitoring his medication, it is important to know that a patient
with liver disease may have impaired drug
A. absorption
B. distribution
C. metabolism
D. excretion.
Answer: C.
Rationale: The liver is mainly involved in drug metabolism. The
gastrointestinal tract is mainly involved in absorption of oral drugs,
the cardiovascular system is concerned with distribution, and the
kidneys are concerned with excretion.
◉ 2.4 A nurse is looking up information about the effects of a drug
on different receptors. Characteristics of receptors include which of
the following?
A. They are carbohydrates located in cell membranes or inside cells.
B. They are constantly synthesized and degraded in the body.
C. They bind with molecules of any drug circulating in the
bloodstream.
, D. They regulate the actions of all drugs..
Answer: D.
Rationale: Receptors are mainly proteins that are manufactured and
eliminated like other proteins in the body. Their numbers and
binding capacities can be increased or decreased in particular
situations. Most receptors bind with relatively few drugs. Some
drugs do not require receptor binding for their actions (e.g., antacids
such as TUMS or Mylanta).
◉ 2.5 A patient with an overdose of an oral drug usually receives
which of the following?
A. specific antidote
B. activated charcoal
C. syrup of ipecac
D. strong laxative.
Answer: B.
Rationale: Activated charcoal is considered the "universal antidote."
Most therapeutic drugs do not have specific antidotes; syrup of
ipecac to induce vomiting with overdoses of some drugs is no longer
recommended (questionable effectiveness, danger of aspiration of
vomitus), and strong laxatives are not indicated.
◉ 2.6 The mother of a 14-month-old girl calls a nurse working in a
pediatric clinic and reports that her daughter ingested an unknown
number of sleeping pills about 4 hours ago and is now drowsy. The
