SECTION A: PHARMACOKINETICS, PHARMACODYNAMICS & FOUNDATIONAL
CONCEPTS
1. A patient with hepatic cirrhosis is prescribed a medication that undergoes
extensive first-pass metabolism. The nurse practitioner understands that
which of the following routes of administration would MOST effectively
bypass the first-pass effect while maintaining therapeutic drug levels?
- A) Oral administration with a high-fat meal
- B) Sublingual administration
- C) Intramuscular injection
- D) Oral administration with grapefruit juice
Answer: B — Sublingual administration
Rationale: The first-pass effect refers to the rapid hepatic metabolism of a
drug before it reaches systemic circulation. When a drug is taken orally, it is
absorbed in the gastrointestinal tract and enters the portal vein to the liver,
where significant metabolism can occur. Sublingual administration (B) allows
the drug to be absorbed directly into the systemic circulation through the
highly vascularized sublingual mucosa, completely bypassing the portal
circulation and first-pass hepatic metabolism. While intramuscular injection
(C) also bypasses the first-pass effect, it does not provide the rapid onset or
,2
ease of administration that sublingual routes offer for certain medications.
Oral administration with food (A) or grapefruit juice (D) may affect absorption
or metabolism but does not bypass the first-pass effect.
2. A patient with a history of chronic kidney disease (Stage 4, eGFR 25
mL/min) is prescribed a medication that is primarily renally excreted. The
nurse practitioner should anticipate which of the following adjustments to the
dosing regimen?
- A) Increase the dose to achieve therapeutic levels
- B) Decrease the dose or extend the dosing interval
- C) No dose adjustment is needed
- D) Switch to a medication with hepatic clearance
Answer: B — Decrease the dose or extend the dosing interval**
Rationale: In patients with significantly reduced renal function (eGFR < 30
mL/min), medications that are primarily renally excreted accumulate, leading
to toxicity. Dose reduction or extended dosing intervals are required to
maintain therapeutic levels while avoiding adverse effects. Option A would
increase the risk of toxicity. Option C would be unsafe. Option D may be
appropriate in some cases but is not always feasible or necessary.
3. A 68-year-old patient with heart failure is started on digoxin. The patient's
serum creatinine is 1.8 mg/dL, and potassium is 3.2 mEq/L. Which of the
following statements about this patient's risk for digoxin toxicity is MOST
accurate?
,3
- A) The patient is at increased risk for digoxin toxicity due to renal
impairment and hypokalemia
- B) The patient is at decreased risk for digoxin toxicity due to age-related
changes in distribution
- C) The patient's risk for digoxin toxicity is unchanged from a younger patient
with normal renal function
- D) The patient is at increased risk for digoxin toxicity only if they also take a
calcium channel blocker
Answer: A — The patient is at increased risk for digoxin toxicity due to renal
impairment and hypokalemia
Rationale: Digoxin toxicity is more likely in patients with renal impairment
(reduced clearance) and hypokalemia (which increases the binding of digoxin
to cardiac sodium-potassium ATPase pumps). Elderly patients are also at
increased risk due to age-related changes in renal function and body
composition. Hypokalemia sensitizes the myocardium to digoxin and increases
the risk of arrhythmias. Option B is incorrect; age-related changes increase,
not decrease, risk. Option C is incorrect. Option D is incomplete; multiple
factors contribute to digoxin toxicity risk.
. A patient is prescribed a medication that is a known substrate of CYP3A4.
The patient also takes grapefruit juice daily. The nurse practitioner should
anticipate which of the following effects on the medication's serum
concentration?
- A) Decreased serum concentration due to increased metabolism
- B) Increased serum concentration due to inhibition of CYP3A4
, 4
- C) No significant change in serum concentration
- D) Decreased serum concentration due to enhanced renal clearance
Answer: B — Increased serum concentration due to inhibition of CYP3A4**
Rationale: Grapefruit juice inhibits intestinal CYP3A4, reducing the
presystemic metabolism of drugs that are substrates of this enzyme. This
leads to increased bioavailability and higher serum concentrations, potentially
causing toxicity. This interaction is particularly significant for medications with
narrow therapeutic indices, such as certain statins, calcium channel blockers,
and immunosuppressants.
5. A patient is prescribed a medication with a half-life of 24 hours. The nurse
practitioner understands that it will take approximately how many days for
the medication to reach steady-state concentration?
- A) 1 day
- B) 3 days
- C) 5 days
- D) 7 days
Answer: C — 5 days
Rationale: Steady-state concentration is reached after approximately 4-5 half-
lives of continuous dosing. With a half-life of 24 hours, steady-state would be
achieved in approximately 4-5 days. Option A (1 day) represents only one half-
life. Option B (3 days) represents approximately 3 half-lives, which is
