LEHNE PHARM GERIATRIC PHARMACOTHERAPY
LATEST UPDATED 2026-2027 ACTUAL FINAL EXAM
WITH WELL ELABORATED 100 PRACTICE
QUESTIONS AND 100% CORRECT DETAILED
ANSWERS WITH VERIFIED RATIONALES A+ GRADE
GUARANTEED MOST RECENT!!!
1. The most significant age-related pharmacokinetic change affecting drug
dosing in older adults is:
A. Increased hepatic enzyme activity
B. Increased renal clearance
C. Decreased renal function
D. Increased gastric emptying
Rationale: Renal clearance declines with age, leading to drug accumulation.
2. Which of the following best describes polypharmacy?
A. Use of one drug for multiple conditions
B. Use of five or more medications concurrently
C. Use of herbal drugs only
D. Use of OTC medications only
Rationale: Polypharmacy is commonly defined as ≥5 medications.
3. The Beers Criteria is primarily used to:
A. Diagnose dementia
B. Adjust insulin doses
C. Identify potentially inappropriate medications in older adults
D. Treat hypertension
Rationale: Beers Criteria lists high-risk medications in geriatrics.
4. Older adults are at increased risk of adverse drug reactions mainly due to:
A. Faster metabolism
, B. Increased body water
C. Multiple comorbidities and drug interactions
D. Improved kidney function
Rationale: Comorbidity and polypharmacy increase ADR risk.
5. Which organ shows the most clinically significant decline in drug elimination
with age?
A. Liver
B. Heart
C. Kidney
D. Pancreas
Rationale: Renal excretion declines significantly in aging.
6. Pharmacodynamics in older adults typically shows:
A. Decreased drug sensitivity
B. Increased sensitivity to some drugs
C. No change
D. Complete resistance
Rationale: CNS and cardiovascular sensitivity often increases.
7. Which drug class is most likely to cause confusion in elderly?
A. Antibiotics
B. Antacids
C. Benzodiazepines
D. Vitamins
Rationale: CNS depressants increase delirium risk.
8. A common cause of medication non-adherence in elderly is:
A. High literacy
B. Excess hydration
C. Cognitive impairment
D. Faster metabolism
Rationale: Memory decline affects adherence.
, 9. Which is a START criteria concept?
A. Stops medications
B. Identifies prescribing omissions
C. Detects overdose
D. Measures renal function
Rationale: START identifies under-prescribing.
10.Aging leads to decreased:
A. Fat mass
B. Total body water
C. Drug half-life
D. Cardiac output increase
Rationale: Reduced body water increases drug concentration.
11.Lipophilic drugs in elderly tend to:
A. Have shorter half-life
B. Have prolonged half-life
C. Be eliminated faster
D. Not distribute
Rationale: Increased fat stores prolong lipophilic drug action.
12.Which is a high-risk drug class in Beers Criteria?
A. Antihypertensives
B. Vitamins
C. Anticholinergics
D. Oral rehydration salts
Rationale: Anticholinergics cause confusion and falls.
13.Falls in elderly are commonly associated with:
A. Antibiotics
B. Antacids
C. Sedatives and hypnotics
D. Vaccines
