HOSA DIGESTIVE HEALTH AND NUTRITION EXAM 2025
|160 QUESTIONS WITH ACCURATE SOLUTIONS
1. Describe the significance of essential amino acids in the context of
protein quality.
Essential amino acids are found only in plant-based proteins.
Essential amino acids can be produced by the body and are not
necessary in the diet.
Essential amino acids are crucial for protein quality because
they must be obtained from the diet, as the body cannot
synthesize them.
Essential amino acids are only important for muscle growth.
2. Which pathogen contributing to a foodborne illness is known as the
'cafeteria germ'?
Staphylococcus aureus
Norovirus
E. Coli
Clostridium perfringens
3. If a patient is diagnosed with arteriosclerosis, which dietary change might
be recommended to support their digestive health?
Reduce protein consumption
Increase fiber intake
Eliminate all fats
Increase sugar intake
,4. Describe how cooking meat and eggs can influence their digestibility.
Cooking has no effect on the digestibility of proteins.
, Cooking increases the fiber content of meat and eggs.
Cooking reduces the nutrient absorption in the intestines.
Cooking meat and eggs denatures proteins, making them easier
to digest.
5. If a person's buffer systems are compromised, what physiological effect
might occur in relation to digestion?
Impaired pH regulation leading to digestive issues
Increased nutrient absorption efficiency
Enhanced enzyme activity in the stomach
Decreased production of bile
6. What is the primary role of buffer systems in the body?
Producing digestive enzymes
Regulating amounts of hydrogen ions in body fluids
Transporting oxygen in the blood
Absorbing nutrients from food
7. Describe the significance of retinol in the context of vitamin A and its role
in human health.
Retinol is significant as it is the active form of vitamin A essential
for vision, immune function, and skin health.
Retinol is a precursor to vitamin D and is important for calcium
absorption.
Retinol is a mineral that supports bone health.
Retinol is a type of fiber that aids in digestion and gut health.
8. What type of tissue is referred to as adipose tissue?
, Fatty tissue
Muscle tissue
Nervous tissue
Connective tissue
9. Describe the role of biotin in metabolism.
Biotin is essential for the production of red blood cells.
Biotin is necessary for metabolism as it helps convert nutrients
into energy.
Biotin is primarily involved in the synthesis of DNA.
Biotin aids in the absorption of minerals in the digestive tract.
10. What is the primary source of dietary fiber?
Cellulose
Glucose
Starch
Fructose
11. Which bacteria is an important cause of food illness because it can
survive in the fridge:
proteus mirabillus
pseudomonas aeruginosa
Staphylococcus aureus
listeria monocytogenes
12. If a patient presents with xerophthalmia, which vitamin deficiency should
be investigated, and what dietary changes could help address this
deficiency?
