Q1.
Which physiological change in the aging kidney most significantly impacts the
pharmacokinetics of renally excreted drugs, and how does it alter the clinical response?
A. Decreased renal blood flow and GFR, B. Increased tubular secretion, leading to
leading to reduced clearance and increased faster elimination and subtherapeutic levels.

C. Reduced tubular reabsorption, causing D. Increased renal mass, enhancing drug
increased urinary loss of water-soluble clearance and necessitating higher doses.
drugs.
Correct: A - Decreased renal blood flow and GFR, leading to reduced clearance and
increased half-life, requiring dose adjustment.
Rationale:Aging kidneys show decreased renal blood flow and GFR, reducing drug clearance
and prolonging half-life. This increases the risk of toxicity, so dose adjustments are necessary.
The other options describe changes not typical of aging.
Q2.
A patient with type 2 diabetes and chronic kidney disease (eGFR 30 mL/min) is being
started on metformin. According to current FDA guidelines, what is the most appropriate
action?
A. Initiate metformin at a reduced dose and B. Avoid metformin entirely due to the risk of
monitor renal function every 3 months. lactic acidosis.
C. Start metformin at full dose but D. Use metformin as first-line but switch to
discontinue if eGFR falls below 30 mL/min. insulin if eGFR declines further.
Correct: A - Initiate metformin at a reduced dose and monitor renal function every 3
months.
Rationale:Current guidelines allow metformin use if eGFR is 30-45 mL/min with reduced
dose and close monitoring. It is contraindicated when eGFR <30, but not entirely avoided. Full
dose is not recommended at this level.
Q3.
Which of the following best describes the mechanism by which sarcopenia contributes to
frailty in older adults?
A. Loss of muscle mass leads to decreased B. Sarcopenia directly causes cognitive
basal metabolic rate and increased fatigue. decline, leading to frailty.

, Section A - Chronic
C. Increased muscle mass leads to higher D. Sarcopenia results from increased
energy expenditure, causing malnutrition. physical activity, causing joint damage.
Correct: A - Loss of muscle mass leads to decreased basal metabolic rate and increased
fatigue.
Rationale:Sarcopenia, age-related loss of muscle mass, reduces strength and metabolic rate,
contributing to frailty, falls, and disability. It does not directly cause cognitive decline; that's
separate. The other options misrepresent the mechanism.
Q4.
A patient with heart failure is prescribed an ACE inhibitor. Which laboratory value requires
immediate attention before administration?
A. Potassium 5.8 mEq/L B. Creatinine 1.2 mg/dL
C. Hemoglobin 12 g/dL D. Sodium 138 mEq/L
Correct: A - Potassium 5.8 mEq/L
Rationale:ACE inhibitors can cause hyperkalemia. A potassium of 5.8 mEq/L is elevated and
increases the risk of arrhythmias. The other values are within normal limits and do not
preclude ACE inhibitor use.
Q5.
A patient with advanced dementia develops aspiration pneumonia. The family requests
that no artificial nutrition be initiated. Which ethical principle primarily supports the
family's decision?
A. Beneficence B. Nonmaleficence
C. Autonomy D. Justice
Correct: C - Autonomy
Rationale:Autonomy respects the patient's right to self-determination, often exercised by
surrogates. Withholding artificial nutrition aligns with the patient's previously expressed
wishes. Nonmaleficence (do no harm) is relevant but not primary; beneficence (do good) and
justice (fairness) are less direct.
Q6.
Which of the following assessment findings is most indicative of delirium rather than
dementia?
A. Acute onset and fluctuating level of B. Gradual progression over years
consciousness
