RASMUSSEN PHARMACOLOGY EXAM 1 –QUESTIONS WITH RATIONALES
SECTION 1: PHARMACOKINETICS – ABSORPTION (Questions 1-25)
1. A nurse is teaching a patient about how medications enter the body. Which
statement by the nurse correctly describes the pharmacokinetic process of drug
absorption?
A) The breakdown of a drug into inactive metabolites by liver enzymes
B) The movement of a drug from its administration site into the bloodstream
C) The transport of a drug from the bloodstream to target tissues
D) The elimination of a drug from the body through the kidneys
Correct Answer: B
Rationale: Absorption is the first phase of pharmacokinetics, defined as the movement
of a drug from its site of administration into the bloodstream. Option A describes
metabolism, option C describes distribution, and option D describes excretion.
2. A patient asks the nurse why the intravenous medication works so quickly
compared to the oral pills they take at home. What is the best explanation the
nurse should provide regarding intravenous drug administration?
A) Intravenous drugs are metabolized more slowly by the liver
B) Intravenous administration delivers the drug directly into the bloodstream, bypassing
absorption barriers
C) Intravenous drugs have a longer duration of action than oral drugs
D) Intravenous administration allows the drug to be excreted more rapidly
, Page 2 of 84
Correct Answer: B
Rationale: Intravenous administration provides 100% bioavailability because the drug
enters the systemic circulation directly, bypassing the absorption phase entirely. This
results in immediate onset of action. Options A, C, and D are incorrect statements
regarding IV administration.
3. A nurse is reviewing factors that affect drug absorption in a patient with
decreased gastric motility. Which factor would most significantly impair the
absorption of an orally administered medication in this patient?
A) Increased gastric pH
B) Decreased gastric emptying time
C) Increased intestinal blood flow
D) Decreased first-pass metabolism
Correct Answer: B
Rationale: Gastric emptying time significantly affects oral drug absorption. When
gastric emptying is decreased (slower), drugs remain in the stomach longer, which can
delay or reduce absorption into the small intestine where most absorption occurs.
4. The nurse is administering a medication that is known to have extensive first-
pass metabolism. Which route of administration would allow this drug to
completely bypass the first-pass effect and achieve the highest bioavailability?
A) Oral administration
B) Sublingual administration
C) Intravenous administration
D) Rectal administration
Correct Answer: C
Rationale: Intravenous administration bypasses first-pass metabolism entirely
because the drug enters the systemic circulation directly. Oral drugs undergo first-pass
metabolism in the liver before reaching systemic circulation. Sublingual and rectal
routes partially bypass first-pass but not completely.
5. A patient with a history of liver disease is prescribed a medication that
undergoes extensive first-pass metabolism. The nurse anticipates that the
prescriber will most likely order which adjustment to the medication regimen?
A) A higher oral dose to compensate for reduced absorption
B) A lower dose or an alternative route to avoid first-pass metabolism
, Page 3 of 84
C) The medication to be given with food to enhance absorption
D) An increased dosing frequency to maintain therapeutic levels
Correct Answer: B
Rationale: In patients with liver disease, first-pass metabolism may be reduced,
leading to higher than expected drug levels. The prescriber would most likely order a
lower dose or an alternative route to avoid first-pass metabolism and prevent toxicity.
6. Which of the following factors would most significantly increase the rate of
absorption of a medication administered via the oral route?
A) Administration with a high-fat meal
B) The drug being highly lipid-soluble
C) The drug being highly water-soluble
D) Decreased blood flow to the gastrointestinal tract
Correct Answer: B
Rationale: Lipid-soluble drugs cross cell membranes more readily than water-soluble
drugs, resulting in faster absorption. High-fat meals can delay absorption, water-soluble
drugs absorb more slowly, and decreased blood flow reduces absorption.
7. The nurse is preparing to administer a medication via the intramuscular route.
Which factor is most important for the nurse to consider regarding absorption of an
intramuscular injection?
A) The pH of the medication solution
B) The blood flow to the muscle tissue
C) The patient's age and gender
D) The time of day the medication is administered
Correct Answer: B
Rationale: Blood flow to the injection site significantly affects absorption from
intramuscular injections. Areas with greater blood flow (such as the deltoid) absorb
medications faster than areas with less blood flow.
8. A patient is prescribed a medication that is 95% protein-bound. The nurse
understands that which statement about this medication is accurate regarding its
distribution and availability?
A) The medication will have a rapid onset of action
B) Only 5% of the drug is available as free, active drug
, Page 4 of 84
C) The medication will be rapidly excreted by the kidneys
D) The medication has a narrow therapeutic index
Correct Answer: B
Rationale: When a drug is 95% protein-bound, only 5% exists as free, unbound drug
capable of producing a pharmacologic effect. The bound portion is inactive and serves
as a reservoir. Option A is incorrect because protein binding delays onset.
9. A nurse is caring for a patient who is taking two highly protein-bound
medications concurrently. What is the primary concern the nurse should have
regarding this drug combination?
A) Increased renal excretion of both medications
B) Competition for protein-binding sites leading to increased free drug levels and
potential toxicity
C) Decreased absorption of both medications from the gastrointestinal tract
D) Enhanced first-pass metabolism of both medications
Correct Answer: B
Rationale: When two highly protein-bound drugs are taken together, they compete for
binding sites on plasma proteins. This displacement can increase the concentration of
free (active) drug, potentially leading to accumulation and toxicity.
10. The nurse is teaching a patient about a newly prescribed medication. Which
statement indicates that the patient correctly understands the concept of drug
distribution?
A) "The medication will be broken down by my liver before it reaches my cells"
B) "The medication will travel through my bloodstream to reach the organs where it
needs to work"
C) "The medication will be eliminated from my body through my kidneys"
D) "The medication will be absorbed from my stomach into my bloodstream"
Correct Answer: B
Rationale: Distribution is the process by which a drug is transported from the
bloodstream to its site of action in tissues and organs. Option A describes metabolism,
option C describes excretion, and option D describes absorption.
11. A patient has low serum albumin levels due to malnutrition. The nurse should
be most concerned about which potential consequence when administering highly
protein-bound medications to this patient?
