Clinical Question Stem (2–4 sentences)
A 58-year-old man with newly diagnosed hypertension asks
whether changing his diet could reduce his cardiovascular risk.
He reports a diet high in processed foods, frequent fast-food
meals, and low fruit/vegetable intake. Based on nutrition–
health relationships, which initial dietary counseling priority
most directly targets population-level risk reduction for
hypertension and CVD?
,Options
A. Advise a low-carbohydrate, high-protein eating pattern.
B. Emphasize sodium reduction and increased potassium-rich
foods.
C. Recommend intermittent fasting 5 days per week.
D. Encourage replacing all fats with margarine and low-fat
products.
Correct Answer
B
Rationales
Correct (B): Reducing sodium intake while increasing
potassium-rich foods (fruits, vegetables) directly lowers blood
pressure and cardiovascular risk; this aligns with nutrition–
disease relationships emphasizing salt–BP links and dietary
patterns that lower population-level risk.
Incorrect (A): Low-carbohydrate, high-protein diets may aid
weight loss but do not directly or consistently target
hypertension mechanisms and carry adherence and lipid-profile
concerns.
Incorrect (C): Intermittent fasting may influence weight but is
not the primary population-level strategy for blood-pressure
reduction and lacks immediate evidence as a hypertension-first-
line intervention.
Incorrect (D): Blanket replacement of all fats with margarine
ignores fat quality; substituting saturated fats with unsaturated
,fats (not hydrogenated margarines) is the appropriate
approach.
Teaching Point
Sodium reduction plus potassium-rich foods is a priority for
hypertension risk reduction.

Clinical Question Stem (2–4 sentences)
A 34-year-old lactating mother asks whether “natural”
supplements guarantee safety for her infant. She reads internet
claims and wants a science-based evaluation. What principle
should you use to assess the supplements’ safety and efficacy
for mother and infant?
Options
A. Assume “natural” equals safe if produced by plants.
B. Evaluate supplements by evidence: dose, bioavailability, and
risk–benefit in lactation.
C. Recommend maximum tolerated doses since breast milk
dilutes exposure.
D. Use only historical/traditional use as the safety standard.
, Correct Answer
B
Rationales
Correct (B): Scientific evaluation requires assessing dosage,
bioavailability, pharmacokinetics in lactation, and documented
risks/benefits—consistent with the science-of-nutrition
principle that biological effects depend on dose and evidence.
Incorrect (A): “Natural” does not guarantee safety; many
natural compounds have potent biological effects and potential
harm.
Incorrect (C): Recommending maximum tolerated doses is
unsafe—breast milk can concentrate or transmit compounds to
infants and requires evidence-based dosing.
Incorrect (D): Historical use may inform hypotheses but cannot
replace controlled evidence for safety in lactation.
Teaching Point
Evaluate supplements by dose, bioavailability, and lactation-
specific risk–benefit evidence.
