Consistency
Flavor
Levels of one or more nutrients
Inclusion or exclusion of specific foods
Feeding intervals
4. What is the primary role of Potassium?
cardiac contractions
, fluid and acid/base balance
regulates neuromuscular activity
all of the above
5. If a dietary plan is low in phosphorus, which health aspect might be
negatively impacted?
Muscle recovery
Vision
Bone health
Skin hydration
6. If an individual practices intermittent fasting, what potential benefits might
they experience related to cellular repair?

Higher caloric intake
Enhanced cellular repair processes
Increased muscle mass
7. If a patient with peritonitis is advised to increase their intake of dark leafy
greens, what benefits might they expect from this dietary change?
Higher levels of saturated fats
Enhanced carbohydrate absorption
Increased intake of B-vitamins and calcium
Improved protein synthesis
,8. What type of cholesterol is increased by trans fat consumption?
LDL cholesterol
HDL cholesterol
Total cholesterol
Triglycerides
9. If a patient is recovering from oral surgery and requires a mechanical soft
diet, which of the following meals would be most appropriate?

risk.
Saturated fat intake has no impact on heart disease risk.

High intake of saturated fat is associated with increased risk of
heart disease due to elevated LDL cholesterol levels.
High intake of saturated fat decreases heart disease risk by lowering
cholesterol levels.
14. What are the key dietary modifications suggested for individuals with heart
failure?
Increased protein, increased carbohydrates, and increased sodium.
Fluid restriction, increased sodium, and increased carbohydrates.
Fluid restriction, decreased sodium, decreased fat, and decreased
