NURS 612 Advanced Pharmacotherapeutics for Special Populations
2026 |Maryville
1. Which physiological factor contributes to the increased risk of toxicity from
highly protein-bound drugs in neonates?
A. Lower levels of serum albumin and competing bilirubin levels
B. Higher levels of serum albumin
C. Decreased total body water percentage
D. Increased alpha-1 acid glycoprotein levels
Answer: A
Rationale: Neonates have lower concentrations of serum proteins, particularly albumin,
and higher levels of endogenous substances like bilirubin that compete for binding sites,
leading to higher free drug fractions and potential toxicity.
2. In the geriatric population, how does the change in body composition
typically affect the distribution of lipophilic drugs like diazepam?
A. Decreased volume of distribution leading to higher peak concentrations
B. Increased volume of distribution leading to a prolonged half-life
C. Reduced absorption through the gastrointestinal tract
D. Faster clearance due to increased hepatic blood flow
Answer: B
Rationale: Geriatric patients typically have an increased percentage of body fat, which
increases the volume of distribution for lipophilic drugs, thereby extending their half-life.
,3. The Pregnancy and Lactation Labeling Rule (PLLR) replaced the old FDA
categories (A, B, C, D, X). Which of the following is a primary requirement of the
PLLR?
A. A single letter grade assigned to every medication
B. Prohibiting the use of any medication during the first trimester
C. A narrative summary of risks, clinical considerations, and data
D. Mandatory clinical trials in pregnant women for all new drugs
Answer: C
Rationale: The PLLR requires a detailed narrative summary for the Pregnancy, Lactation,
and Females and Males of Reproductive Potential subsections, moving away from
oversimplified letter categories.
4. Why are fluoroquinolones generally avoided in the pediatric population
unless the benefit clearly outweighs the risk?
A. Potential for permanent tooth discoloration
B. Risk of premature closure of the epiphyses
C. Potential for tendon rupture and cartilage damage
D. High risk of Reye’s syndrome
Answer: C
Rationale: Fluoroquinolones are associated with arthropathy and potential cartilage
damage in weight-bearing joints in animal studies, leading to caution in pediatric use.
5. When calculating the renal clearance of a 75-year-old patient, which equation
is most commonly utilized in clinical practice despite its limitations?
A. Cockcroft-Gault equation
B. Schwartz formula
C. Body Surface Area method
D. Fried’s Rule
Answer: A
, Rationale: The Cockcroft-Gault equation is the standard clinical tool for estimating
creatinine clearance to adjust drug dosages in the elderly, although it can overestimate
GFR.
6. A pregnant patient in her third trimester requires medication. How does the
increased maternal plasma volume affect the pharmacokinetics of hydrophilic
drugs?
A. It has no effect on water-soluble medications
B. It decreases the volume of distribution, requiring lower doses
C. It increases the volume of distribution, potentially requiring higher doses
D. It increases protein binding, reducing the free drug available
Answer: C
Rationale: During pregnancy, maternal plasma volume expands by up to 50%, which
increases the volume of distribution for hydrophilic drugs, often necessitating dose
adjustments.
7. Which of the following is a key consideration of the Beers Criteria regarding
the use of diphenhydramine in the elderly?
A. It is recommended for use as a first-line sleep aid
B. It is avoided due to risks of confusion, blurred vision, and urinary retention
C. It should be avoided due to high anticholinergic clearance
D. It is only safe in patients with a history of glaucoma
Answer: B
Rationale: The Beers Criteria lists diphenhydramine as potentially inappropriate for the
elderly because of its strong anticholinergic effects, which increase the risk of cognitive
impairment, falls, and urinary retention.
