NYSTCE Health Education Exam Prep 1 — Questions and Answers
Question 1: How many calories are in one gram of protein?
- 1
- 7
- 9
- 4 (Correct answer)
Correct answer: 4
Proteins are one of the three macronutrients that provide energy to the human body. Each gram of protein supplies approximately 4 kilocalories (often simply referred to as calories) of energy. This caloric value is a key component in understanding nutritional content and dietary energy intake.
Question 2: Nutrient availability is influenced by:
- Size
- Solubility
- Interaction with other food and nutrients
- All of the above (Correct answer)
Correct answer: All of the above
Nutrient availability, also known as bioavailability, is influenced by a complex interplay of factors. The physical size of food particles, the solubility of nutrients in the digestive tract, and their interactions with other food components or nutrients all impact how efficiently they are absorbed and utilized by the body. Therefore, all these elements collectively determine how much of a nutrient is truly available.
Question 3: When an individual is excreting more nitrogen than being consumed they are:
- Anemic
- In negative nitrogen balance (Correct answer)
- In positive nitrogen balance
- Cachexic
Correct answer: In negative nitrogen balance
Nitrogen balance is a measure of protein metabolism, comparing nitrogen intake to nitrogen excretion. When an individual excretes more nitrogen than they consume, it indicates that the body is breaking down more protein (e.g., muscle tissue) than it is synthesizing. This state is known as negative nitrogen balance and often occurs during periods of illness, injury, or insufficient protein intake.
Question 4: Which of the following is an enzyme:
- Lipase (Correct answer)
- Sterol
- Sucrose
- Phosphatidyl choline
Correct answer: Lipase
Lipase is a specific type of enzyme that plays a crucial role in the digestion of fats (lipids). It catalyzes the hydrolysis of fats into smaller molecules like fatty acids and glycerol, making them absorbable by the body. Sterols, sucrose, and phosphatidyl choline are not enzymes; they are types of lipids, sugars, and phospholipids, respectively.
Question 5: Magnesium excess may cause hypocalcemia by:
- Modulating PTH release (Correct answer)
- Aiding Ca uptake in the intestine
- Using a cofactor in an enzyme needed to cleave Ca into elemental form
- None of the above
Correct answer: Modulating PTH release
Excess magnesium can disrupt calcium homeostasis by modulating the release of parathyroid hormone (PTH). High magnesium levels can suppress PTH secretion, and PTH is vital for maintaining normal blood calcium levels by promoting calcium release from bones and reabsorption in the kidneys. Reduced PTH activity consequently leads to decreased serum calcium, resulting in hypocalcemia.
Question 6: Antioxidants are:
- Compounds that inhibit hydrogens
- Compounds that create free radicals
- Compounds that are bacteriolytic
- Compounds that inhibit damaging oxidizing agents (Correct answer)
Correct answer: Compounds that inhibit damaging oxidizing agents
Antioxidants are compounds that protect cells from damage caused by harmful molecules called free radicals. They achieve this by inhibiting or neutralizing these damaging oxidizing agents, often by donating electrons to stabilize them. This protective action is crucial for maintaining cellular integrity and overall health.
Question 7: Women of childbearing age are urged to take folic acid supplements because:
- Deficiency may result in internal bleeding
- Deficiency increases gestation period of child
- Deficiency may result in neural tube defects in infants (Correct answer)
- Sufficiency is associated with higher social economic status
Correct answer: Deficiency may result in neural tube defects in infants
Folic acid (folate) is a B vitamin essential for proper cell division and the healthy development of the neural tube, which forms the brain and spinal cord in a fetus. Adequate intake of folic acid before and during early pregnancy significantly reduces the risk of neural tube defects, such as spina bifida, in infants. This is why supplementation is strongly recommended for women of childbearing age.
Question 8: The benefits of breastfeeding include:
- Sensitizes infant to diet of mother
- Increases mother infant pair bonding
- Weight loss for mother
- All of the above (Correct answer)
Correct answer: All of the above
Breastfeeding offers a wide range of benefits for both the infant and the mother. For the baby, it provides optimal nutrition, antibodies, and can sensitize them to the mother's diet. For the mother, it aids in postpartum weight loss and strengthens the mother-infant bond, encompassing all the listed advantages.
Question 9: How many calories are equivalent to a pound?
- 3500 (Correct answer)
- 3300
- 3000
- 1300
Correct answer: 3500
A widely accepted nutritional estimate states that one pound of body fat is equivalent to approximately 3,500 kilocalories (often referred to simply as calories). This conversion is a fundamental principle in weight management, guiding individuals in understanding the caloric balance needed for weight loss or gain.
Question 10: Cooling down after rigorous exercise is important as abrupt cessation may result in blood pooling in the legs, consequently resulting in:
- Varicose veins
- Fainting
- Cardiac complications
- B and C (Correct answer)
Correct answer: B and C
Abruptly stopping rigorous exercise can lead to blood pooling in the extremities, especially the legs, due to the sudden cessation of the muscle pump action. This can cause a rapid drop in blood pressure, potentially leading to fainting (syncope) as less blood returns to the heart and brain. In some cases, this physiological stress can also contribute to cardiac complications, making a gradual cool-down crucial for cardiovascular safety.
Question 11: The ABCs of CPR refer to:
- Airway, breathing, circulation (Correct answer)
- Airway, blockage, cardiac
- Append, breakage, circulation
- Append, breathing, cardiac
Correct answer: Airway, breathing, circulation
The ABCs of CPR stand for Airway, Breathing, and Circulation, representing the critical sequence of actions to take during cardiopulmonary resuscitation. This mnemonic guides rescuers to first ensure an open airway, then check for and assist breathing, and finally assess and support circulation to maintain vital organ function and improve patient outcomes.
Question 12: In the event of an injury or minor wound, providing first-aid is necessary in which order:
- Clean, stop the bleeding, apply antibiotic, cover
- Stop the bleeding, clean, apply antibiotic, cover (Correct answer)
- Apply antibiotic, stop the bleeding, clean, cover
- Stop the bleeding, apply antibiotic, clean, cover
Correct answer: Stop the bleeding, clean, apply antibiotic, cover
When providing first aid for an injury or minor wound, the immediate priority is to stop any bleeding to prevent further blood loss. Once bleeding is controlled, the wound should be thoroughly cleaned to remove dirt and bacteria, followed by the application of an antibiotic to prevent infection. Finally, covering the wound protects it from further contamination and aids in the healing process.
Question 13: One side effect of anorexia nervosa is amenorrhea, which is:
- Atrophy of muscles
- Excessive urination
- Cessation of menstrual cycle (Correct answer)
- Excessive arm hair growth
Correct answer: Cessation of menstrual cycle
Amenorrhea refers to the absence or cessation of the menstrual cycle. In individuals with anorexia nervosa, severe calorie restriction and extremely low body fat levels disrupt the hormonal balance necessary for regular menstruation. The body conserves energy by shutting down non-essential functions, including the reproductive system, leading to amenorrhea.
Question 14: Those who suffer from Bulimia often use excessive laxatives for weight loss, however, this is:
- Effective but dangerous to epithelial lining of intestinal tract
- Ineffective as nutrients/calories have already been absorbed (Correct answer)
- Not a common method of weight loss used by Bulimics
- Effective, and not considered harmful
Correct answer: Ineffective as nutrients/calories have already been absorbed
Using laxatives for weight loss, common in bulimia, is ineffective for reducing calorie absorption. Most nutrients and calories are absorbed in the small intestine, whereas laxatives primarily act on the large intestine to promote water and electrolyte excretion. Therefore, laxative abuse leads to dehydration and electrolyte imbalances, not significant calorie loss.
Question 15: A common health misconception is:
- Trans-fat is linked to heart disease
- All fat is bad (Correct answer)
- We need essential fatty acids
- All of the above
Correct answer: All fat is bad
The idea that 'all fat is bad' is a common health misconception. While some fats, like trans fats and excessive saturated fats, can be detrimental, healthy fats are essential for bodily functions. Monounsaturated and polyunsaturated fats, found in foods like avocados, nuts, and olive oil, are crucial for energy, hormone production, and nutrient absorption, and can even improve heart health.
Question 16: Alcohol consumption lowers blood glucose by:
- Blunting insulin release
- Increases glucose uptake by the liver
- Inhibits gluconeogenesis (Correct answer)
- None of the above
Correct answer: Inhibits gluconeogenesis
Alcohol consumption lowers blood glucose primarily by inhibiting gluconeogenesis. The liver, which is responsible for producing new glucose (gluconeogenesis) when blood sugar is low, prioritizes metabolizing alcohol. This process generates byproducts that interfere with glucose production, leading to a drop in blood sugar, especially in individuals with depleted glycogen stores or those who haven't eaten.
Question 17: Protein supplements alone (such as whey powder) increases muscle gain:
- True, but only with appropriate water consumption to aid in the excretion of harmful nitrite metabolites
- False, excess protein is stored as fat (Correct answer)
- True, but only if the protein is an enantiomer
- None of the above
Correct answer: False, excess protein is stored as fat
Protein supplements alone do not automatically increase muscle gain without resistance training. The body requires a combination of adequate protein intake, sufficient overall calories, and physical stimulation from exercise to build muscle tissue. Any excess protein consumed beyond the body's needs for repair and growth will be converted and stored as fat, not muscle.
Question 18: How much daily fiber intake is recommended?
- No strict recommendation has been set
- 10 grams
- 20-30 grams (Correct answer)
- <100grams
Correct answer: 20-30 grams
The recommended daily fiber intake for adults is generally 20-30 grams. Fiber is crucial for maintaining digestive health, regulating blood sugar levels, lowering cholesterol, and promoting satiety. Consuming adequate fiber contributes significantly to overall well-being and can help prevent various chronic diseases.
Question 19: Fiber is defined as:
- Any material found in both fruits and vegetables that is water soluble
- A substance which inhibits diarrhea
- Any material found in both fruits and vegetables that is lipid insoluble
- None of the above (Correct answer)
Correct answer: None of the above
Fiber is a type of carbohydrate found in plant-based foods that the human body cannot digest or absorb. It is broadly categorized into soluble fiber (which dissolves in water) and insoluble fiber (which does not). The provided options do not accurately or comprehensively define fiber, making 'None of the above' the correct choice.
Question 20: Regular exercise has positive effects on cardiac system by:
- Releasing protective heart hormones
- Increasing reflex arc timing
- Increasing cholesterol metabolism and excretion
- Increasing muscle mass in heart (Correct answer)
Correct answer: Increasing muscle mass in heart
Regular exercise positively impacts the cardiac system by strengthening the heart muscle itself. Similar to other muscles, the heart adapts to the demands of exercise by becoming larger and more efficient. A stronger heart can pump more blood with each beat, leading to a lower resting heart rate and improved overall cardiovascular function.
Question 21: Regular exercise has positive effects on the circulatory system by:
- Increased blood flow (Correct answer)
- Decreased blood volume
- Decreased excretion of CO2
- All of the above
Correct answer: Increased blood flow
Regular exercise enhances the efficiency of the circulatory system primarily by increasing blood flow. A stronger heart pumps blood more effectively, and blood vessels become more flexible and dilated, allowing for better circulation. This improved blood flow ensures that oxygen and nutrients are delivered more efficiently to all tissues and organs, while waste products are removed more effectively.
Question 22: Characteristics of an effective health education curriculum include:
- Addressing social pressures and influences
- Addressing individual values, attitudes, and beliefs
- Is research-based and theory-driven
- All of the above (Correct answer)
Correct answer: All of the above
An effective health education curriculum is comprehensive and addresses multiple facets of health behavior. It must consider social pressures and influences that impact choices, acknowledge individual values, attitudes, and beliefs, and be grounded in scientific research and established theories to ensure its efficacy and relevance.
Question 23: Age-appropriate information for effective health education curriculum should:
- Address students’ desires
- Address students’ emotional maturity (Correct answer)
- Incorporate popular culture references
- Age appropriate information is not necessary
Correct answer: Address students’ emotional maturity
Age-appropriate information in health education is crucial for effective learning. It means tailoring content to match students' cognitive abilities and, importantly, their emotional maturity. Presenting information in a way that resonates with their developmental stage helps students understand, process, and apply health concepts to their lives more effectively.
Question 24: Learned behavior change requires:
- Repeated effort
- Intensive and sustained effort
- “One-shot” approaches
- A and B, but not C (Correct answer)
Correct answer: A and B, but not C
Learned behavior change is a complex and ongoing process that requires both repeated and intensive, sustained effort. 'One-shot' approaches are generally ineffective because new habits and attitudes need consistent reinforcement and practice to become ingrained. Long-term commitment and persistence are key to achieving lasting behavioral modifications.
Question 25: Effective curriculum includes material that is free of cultural bias, but includes information regarding:
- Gender, race, ethnicity, religion, age but not sexual orientation
- Gender, ethnicity, religion, age, sexual orientation but not race
- Gender, race, ethnicity, religion, age and sexual orientation (Correct answer)
- Gender, race, religion, age, sexual orientation but not ethnicity
Correct answer: Gender, race, ethnicity, religion, age and sexual orientation
An effective health education curriculum must be inclusive and free of cultural bias, acknowledging the diverse identities of its students. This means incorporating information and perspectives relevant to all aspects of identity, including gender, race, ethnicity, religion, age, and sexual orientation, to ensure all students feel represented and understood.
Question 26: Why is goal setting important?
- Helps individuals feel accomplished
- Helps individuals focus on specific tasks (Correct answer)
- Improves the likelihood of continuing with exercise routine once goal has been attained
- B and C
Correct answer: Helps individuals focus on specific tasks
Goal setting is important because it helps individuals focus their efforts on specific tasks and actions. By establishing clear, measurable goals, individuals gain direction and purpose, making it easier to prioritize activities and concentrate on what is needed to achieve desired health outcomes. This focus enhances motivation and makes the path to improvement more manageable.
Question 27: What are some benefits of stretching?
- Stretching has no proven benefits
- Decreases stress, improves focus
- Improves coordination and prevents injuries (Correct answer)
- None of the above
Correct answer: Improves coordination and prevents injuries
Regular stretching offers several proven benefits, including improved coordination and injury prevention. By increasing flexibility and range of motion, stretching helps muscles and joints move more efficiently, reducing the risk of strains, sprains, and other injuries during physical activity. It also contributes to better balance and overall physical performance.
Question 28: What are classes of fats?
- Saturated, unsaturated, polysaturated
- Saturated, monounsaturated, polyunsaturated (Correct answer)
- Unsaturated, monosaturated, polyunsaturated
- Saturated, unsaturated, polysaturated
Correct answer: Saturated, monounsaturated, polyunsaturated
Dietary fats are primarily classified into three main categories based on their chemical structure: saturated, monounsaturated, and polyunsaturated. These classifications refer to the number of double bonds present in the fatty acid chains, which influences their physical properties and health effects.
Question 29: How many essential amino acids are there?
- 9 (Correct answer)
- 3
- 12
- 21
Correct answer: 9
There are nine essential amino acids that the human body cannot synthesize on its own and must obtain through dietary sources. These include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine, all of which are vital for protein synthesis and numerous physiological functions.
Question 30: Saturated fatty acids are: A. Fats with no double bonds
- Fats with no double bonds (Correct answer)
- Fats with double bonds
- Fats which are bonded to a glycerol molecule
- All of the above
Correct answer: Fats with no double bonds
Saturated fatty acids are characterized by having only single bonds between carbon atoms in their hydrocarbon chains. This means they are 'saturated' with hydrogen atoms and lack any double bonds. This molecular structure typically makes them solid at room temperature, distinguishing them from unsaturated fats.
