Q1 QUESTION 1 OF 319
Nutrition
Page 1
, CORRECT ANSWER
provides the body with the nutrients it needs to perform its daily tasks
RATIONALE
Nutrition is the process of consuming and utilizing food for growth, metabolism, and repair, ensuring the body receives necessary
macronutrients and micronutrients for energy and physiological function. This intake fuels cellular processes and maintains homeostasis,
enabling all bodily systems to operate effectively.
Q2 QUESTION 2 OF 319
Undernutrition
CORRECT ANSWER
implies that the individual is not getting enough nutrients. This can occur even if the person is consuming more than enough
calories
RATIONALE
Undernutrition signifies an insufficient intake of essential nutrients, irrespective of caloric consumption, highlighting the distinction
between energy and nutrient adequacy. This concept emphasizes that adequate calorie intake alone does not guarantee optimal
nutritional status.
Q3 QUESTION 3 OF 319
Malnutrition
CORRECT ANSWER
an imbalance of proper nutrients
RATIONALE
Malnutrition signifies a state where the body lacks or has an excess of essential nutrients, disrupting normal physiological functions. This
imbalance fundamentally impairs cellular processes and health.
Q4 QUESTION 4 OF 319
Anorexia nervosa
CORRECT ANSWER
literally means loss of appetite, but this is a misnomer: A person with this is hungry, but denies the hunger because of an irrational
fear of becoming fat. Self-starvation, food preoccupation and rituals, compulsive exercising, and often an absence of menstrual
cycles in women.
Untreated, can be fatal.
RATIONALE
Anorexia nervosa is a misnomer as individuals experience hunger but suppress it due to an intense fear of weight gain, leading to self-
starvation and potentially fatal consequences. This condition is characterized by food preoccupation, compulsive behaviors like
exercising, and amenorrhea in women.

, Q5 QUESTION 5 OF 319
Bulimia
CORRECT ANSWER
characterized by recurring periods of binge eating, during which large amounts of food are consumed in a short period of time
followed by purging (through self-induced vomiting, abuse of laxatives and/or diuretics) or periods of fasting
RATIONALE
Bulimia nervosa is defined by recurrent episodes of uncontrolled binge eating coupled with compensatory behaviors, such as purging or
fasting, to prevent weight gain. This cycle reflects a core disturbance in impulse control and body image.
Q6 QUESTION 6 OF 319
Binge eating disorder (BED)
CORRECT ANSWER
episodes of binge eating characterized by eating rapidly, eating large amounts of food even when not feeling hungry, and feeling
guilty or depressed after overeating.
RATIONALE
Binge eating disorder is defined by recurrent episodes of consuming significantly more food than normal in a discrete period,
accompanied by a sense of lack of control, and followed by distress, guilt, or depression. This pattern distinguishes it from other eating
disorders due to the absence of compensatory behaviors like purging.
Q7 QUESTION 7 OF 319
Obesity
CORRECT ANSWER
15 to 20 percent above normal weight. Poor dietary patterns; include increased intake of sugars in sweetened soft drinks, foods, and
meals of high energy, low nutrient density, and large portion sizes. At risk for serious health problems such as type 2 diabetes,
hypertension, heart disease, stroke, and some types of cancer.
RATIONALE
Obesity is defined as being 15-20% above normal weight, often resulting from high-energy, low-nutrient-density diets and large
portions, placing individuals at risk for chronic diseases like type 2 diabetes and hypertension. This condition signifies a complex
interplay of dietary habits and metabolic state, leading to significant health sequelae.
Q8 QUESTION 8 OF 319
Nutrients
CORRECT ANSWER
the substances in food needed to support life functions. provide energy that the body needs
Page 3
, RATIONALE
Nutrients are essential compounds from food that fuel metabolic processes and cellular repair, enabling the body to perform all life-
sustaining functions. They provide the caloric energy required for physical activity and maintaining homeostasis.
Q9 QUESTION 9 OF 319
Kilocalorie (or Calorie)
CORRECT ANSWER
the amount of heat energy required to raise the temperature of one kilogram of water one degree Celsius
RATIONALE
This definition highlights the fundamental concept of energy as heat transfer, specifically quantifying the energy needed to elevate
water's temperature by a defined increment. This establishes the kilocalorie as a unit of thermodynamic energy measurement.
Q10 QUESTION 10 OF 319
Basal metabolism
CORRECT ANSWER
the minimum amount of energy required by the body to maintain essential body functions (e.g., to maintain a normal body
temperature, muscle tone, respiration) when at rest
RATIONALE
Basal metabolism represents the energy expenditure necessary for sustaining vital physiological processes, such as thermoregulation
and respiration, in a complete state of rest and fasting. This core metabolic rate is foundational for all cellular activity and homeostasis.
Q11 QUESTION 11 OF 319
Antibodies
CORRECT ANSWER
combat infection. Synthesized from proteins in response to infectious agent. destroy or lessen the effects of the invading antigen.
RATIONALE
Antibodies are proteins produced by B lymphocytes that bind specifically to antigens, neutralizing pathogens or marking them for
destruction by other immune cells to combat infection. This process exemplifies the adaptive immune system's targeted response to
foreign invaders.
Q12 QUESTION 12 OF 319
Parkinson's disease
CORRECT ANSWER
A chronic, progressive neurological condition that causes tremors and other symptoms.
