1.
A 72-year-old patient reports increasing fatigue, constipation, cold
intolerance, and weight gain. Which laboratory finding most strongly
supports primary hypothyroidism?
A. Low TSH and high free T4
B. High TSH and high free T4
C. High TSH and low free T4
D. Low TSH and low free T4
Rationale: Primary hypothyroidism results from thyroid gland
dysfunction, causing low free T4 with compensatory elevation of TSH.
2.
A 68-year-old patient with hypertension has an estimated GFR of 42
mL/min/1.73 m². Which stage of chronic kidney disease is present?
A. Stage 1
B. Stage 2
C. Stage 3a
D. Stage 4
Rationale: Stage 3a CKD corresponds to an eGFR of 45–59, while an
eGFR of 30–44 is classified as stage 3b. Therefore, an eGFR of 42
indicates stage 3b, making none of the listed choices fully correct.
The correct classification is Stage 3b.
,3.
Which screening recommendation is most appropriate for an
average-risk 70-year-old adult with no previous colorectal cancer
screening?
A. No screening is recommended after age 65
B. Screening should occur annually with abdominal CT
C. Screening may be appropriate based on overall health, life
expectancy, and prior screening history
D. Colonoscopy is mandatory every year
Rationale: Colorectal cancer screening decisions in adults aged 76–85
should be individualized according to health status, life expectancy,
and previous screening.
4.
An older adult taking warfarin begins treatment with trimethoprim-
sulfamethoxazole. What is the primary concern?
A. Reduced INR
B. Hypercalcemia
C. Increased INR and bleeding risk
D. Severe hypoglycemia
Rationale: Trimethoprim-sulfamethoxazole can significantly increase
warfarin's anticoagulant effect, requiring closer INR monitoring and
possible dose adjustment.
5.
A 75-year-old patient presents with new-onset atrial fibrillation.
Which assessment is most important when determining the need for
anticoagulation?
A. Body mass index
B. Serum sodium
,C. Stroke risk using an appropriate validated risk score
D. Pulmonary function testing
Rationale: Stroke-risk assessment, commonly using CHA₂DS₂-VASc,
helps determine whether anticoagulation is indicated in atrial
fibrillation.
6.
Which finding is most characteristic of iron-deficiency anemia?
A. Macrocytosis
B. Elevated ferritin
C. Low ferritin and microcytosis
D. Elevated mean corpuscular volume
Rationale: Iron deficiency typically produces depleted iron stores,
reflected by low ferritin, and eventually causes microcytic,
hypochromic anemia.
7.
A 79-year-old patient develops sudden unilateral weakness and
difficulty speaking. What is the priority action?
A. Schedule an outpatient MRI
B. Administer oral aspirin before evaluation
C. Activate emergency stroke evaluation immediately
D. Reassure the patient that symptoms may resolve
Rationale: Sudden focal neurologic deficits suggest acute stroke.
Rapid emergency evaluation is essential because time-sensitive
reperfusion therapies may be available.
8.
Which medication is generally considered potentially inappropriate
in many older adults because of its anticholinergic effects?
, A. Acetaminophen
B. Diphenhydramine
C. Amoxicillin
D. Calcium carbonate
Rationale: Diphenhydramine has strong anticholinergic effects that
can contribute to confusion, urinary retention, constipation, and falls
in older adults.
9.
A 70-year-old patient reports dizziness when standing. Orthostatic
measurements show a significant fall in blood pressure after
standing. What is the most appropriate initial intervention?
A. Increase antihypertensive medications
B. Restrict all fluids
C. Review medications and assess hydration status
D. Recommend prolonged bed rest
Rationale: Medication effects and volume depletion are common
contributors to orthostatic hypotension and should be evaluated first.
10.
Which finding is most suggestive of heart failure with reduced
ejection fraction?
A. Normal ventricular systolic function
B. Left ventricular ejection fraction of 35%
C. Increased serum HDL
D. Sinus bradycardia alone
Rationale: An LVEF of 40% or less is generally consistent with heart
failure with reduced ejection fraction.
