, Question 1
In an older adult with reduced renal clearance, which change in drug handling
most directly explains increased risk of toxicity from renally eliminated drugs
even when serum creatinine appears normal?
A. Decreased hepatic first-pass metabolism
B. Reduced lean body mass and total body water
C. Age-related decline in glomerular filtration rate not reflected by
creatinine
D. Increased serum albumin binding of acidic drugs
Correct Answer: C - Age-related decline in glomerular filtration
rate not reflected by creatinine
RATIONALE
GFR declines with age while creatinine may remain normal due to
reduced muscle mass, masking renal impairment and increasing drug
exposure. Decreased first-pass metabolism affects hepatic clearance,
not renal elimination. Reduced lean mass and water alter volume of
distribution, not clearance. Albumin binding typically decreases,
increasing free drug but not the primary renal toxicity mechanism.
Question 2
A patient with chronic heart failure and preserved ejection fraction reports new
orthopnea and a 3-lb weight gain over 2 days. Which assessment finding is the
most sensitive early indicator of volume overload?
A. Jugular venous distention
B. Bibasilar crackles
C. Peripheral edema
D. S3 gallop
Correct Answer: A - Jugular venous distention
Page 2
, RATIONALE
JVD reflects elevated right atrial pressure and often precedes
pulmonary congestion and edema in HFpEF. Crackles indicate
alveolar fluid and are a later finding. Peripheral edema is nonspecific
and may be chronic. S3 gallop suggests volume overload but is less
specific and may be absent in HFpEF.
Question 3
Which physiologic change of aging most directly increases the risk of
hyperthermia and heat-related illness during a summer heat wave?
A. Decreased sebaceous gland activity
B. Reduced sweat gland output and cutaneous vasodilation
C. Increased subcutaneous fat thickness
D. Decreased basal metabolic rate
Correct Answer: B - Reduced sweat gland output and cutaneous
vasodilation
RATIONALE
Aging reduces sweat production and skin blood flow, impairing heat
dissipation and raising hyperthermia risk. Sebaceous gland changes
affect skin lubrication, not thermoregulation. Increased subcutaneous
fat may insulate but is not the primary mechanism. Lower metabolic
rate reduces heat production but does not explain impaired dissipation.
Question 4
A patient with advanced dementia and dysphagia has recurrent aspiration
pneumonia. Which intervention best reflects current evidence for reducing
aspiration risk while honoring comfort-focused goals?
A. Routine use of a nasogastric tube for feeding
B. Thickened liquids and upright positioning during meals
C. NPO status with intravenous fluids only
D. Percutaneous endoscopic gastrostomy placement
Page 3
, Correct Answer: B - Thickened liquids and upright positioning
during meals
RATIONALE
Thickened liquids and upright positioning are evidence-based,
low-burden strategies that reduce aspiration and align with comfort
goals in advanced dementia. NG tubes and PEG placement do not
prevent aspiration and may increase discomfort. NPO with IV fluids
does not meet nutritional needs and may worsen quality of life.
Question 5
Which statement best explains why the Beers Criteria are used as a screening
tool rather than an absolute prohibition in older adults?
A. They apply only to patients over 85 years
B. They identify medications that are potentially inappropriate, requiring
clinical judgment for individualization
C. They are based solely on cost-effectiveness data
D. They replace the need for renal dose adjustment
Correct Answer: B - They identify medications that are
potentially inappropriate, requiring clinical judgment for
individualization
RATIONALE
Beers Criteria list potentially inappropriate medications in older
adults, but decisions must be individualized based on goals, benefits,
and risks. They are not age-restricted to over 85 and are not based
solely on cost. They do not replace renal dosing adjustments.
Question 6
Which finding in an older adult with chronic obstructive pulmonary disease
most strongly suggests chronic hypoxemia rather than an acute exacerbation?
A. Increased sputum production
