Questions with Verified Answers and Detailed
Rationales Grade A Study Guide
1. A client has hypoalbuminemia based on nutritional intake and laboratory findings.
Why is this critical for the nurse to consider regarding medication administration?
A. It increases the risk of renal excretion of the drug.
B. It affects the distribution of drugs to target tissues.
C. It enhances the drug's first-pass metabolism.
D. It decreases the potential for drug-drug interactions.
CORRECT ANSWER: B
Rationale: Albumin is a major plasma protein that binds to many drugs.
Hypoalbuminemia decreases protein binding, leading to higher levels of free, active drug
in the bloodstream. This alters drug distribution and increases the risk of toxicity,
especially for highly protein-bound medications.

2. The nurse understands that drugs with a significant first-pass effect have which
primary characteristic?
A. They are primarily excreted unchanged by the kidneys.
B. They are rapidly metabolized by the liver, which may reduce their therapeutic effect.
C. They are best administered via the transdermal route.
D. They have a prolonged duration of action.
CORRECT ANSWER: B
Rationale: The first-pass effect refers to the extensive hepatic metabolism of an oral
drug before it reaches the systemic circulation. This can significantly reduce the
bioavailability and intended therapeutic action of the medication.
3. The nurse is caring for a client receiving a volatile gaseous anesthetic. The primary
route of excretion for this drug will be the:
A. Kidneys.
B. Liver.
C. Lungs.
D. Sweat glands.
CORRECT ANSWER: C
Rationale: Volatile drugs, such as gaseous anesthetics, are primarily eliminated via

exhalation through the lungs. They are not metabolized for excretion by the liver or
kidneys in a significant way.
4. On a serum drug concentration curve, the point indicating the first sign of a
therapeutic effect is known as the:
A. Peak level.
B. Trough level.
C. Onset of action.
D. Duration of action.
CORRECT ANSWER: C
Rationale: The onset of action is the time it takes after administration for a drug to
produce a measurable therapeutic response. It is the initial point on the drug
concentration curve where the minimum effective concentration is reached.
5. Which factor is a primary determinant of a drug's absorption in the stomach?
A. The drug's lipid solubility.
B. The client's glomerular filtration rate.
C. The drug's degree of ionization in the small intestine.
D. The client's liver enzyme activity.
CORRECT ANSWER: A
Rationale: Lipid-soluble drugs can more easily pass through the lipid bilayer of cell

membranes in the gastrointestinal tract. This makes lipid solubility a key factor
influencing the rate and extent of gastric drug absorption.
6. The nurse knows that bioavailability is a particularly important consideration for
which class of drugs?
A. Drugs with a wide therapeutic index.
B. Drugs administered intravenously.
C. Drugs with narrow therapeutic ranges or sustained-release mechanisms.
D. Topical drugs.
CORRECT ANSWER: C
Rationale: Bioavailability refers to the fraction of an administered dose that reaches the
systemic circulation. For drugs with a narrow therapeutic range (where the difference
between a therapeutic and toxic dose is small) or sustained-release formulations, small
variations in bioavailability can lead to treatment failure or toxicity.
7. A client has been receiving a medication at the same dose via continuous IV infusion
for 24 hours. The nurse explains that the client has likely reached "steady state." What
does this term mean?
A. The drug is no longer effective.
B. The amount of drug administered equals the amount eliminated per unit of time, so
the plasma level remains constant.
