WGU C458 HWF
Pass the WGU C458 exam 2025/2026 with confidence. This exam resource
features questions in areas like: knowledge of health, wellness, nutrition,
and fitness concepts. It is best suited for students pursuing nursing,
healthcare, and health science degrees at WGU.
Nutrition ....... ANSWER ........provides the body with the nutrients
it needs to perform its daily tasks
Undernutrition ....... ANSWER ........implies that the individual is not
getting enough nutrients. This can occur even if the person is
consuming more than enough calories
Malnutrition ....... ANSWER ........an imbalance of proper nutrients
Anorexia nervosa ....... 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.
, Bulimia ....... ANSWER ........characterized by recurring periods of
binge eating, during which large amounts of food are consumed in a
Page | 2 short period of time followed by purging (through self-induced
vomiting, abuse of laxatives and/or diuretics) or periods of fasting
Binge eating disorder (BED) ....... 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.
Obesity ....... 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.
Minerals ....... ANSWER ........inorganic material. Form body parts
(teeth and bones), maintain acid-base neutrality, regulate nerve
impulses, osmotic pressure, and electrolyte balance
Major minerals ....... ANSWER ........needed by the body:
• calcium—milk, cheese, sardines, salmon, green vegetables
• phosphorus—milk, cheese, lean meat
• potassium—oranges, bananas, dried fruits
• sulfur—eggs, poultry, fish
, • sodium—table salt, beef, eggs, cheese
• chloride—table salt, meat
• magnesium—green vegetables, whole grains

Trace minerals ....... ANSWER ........required in lesser amounts, and
include iron, zinc, selenium, magnesium, copper, iodine, fluorine,
chromium, molybdenum, and manganese
HDL cholesterol (high density lipoproteins) ....... ANSWER
........protect the body against heart disease. Often called "good"
cholesterol.
LDL cholesterol (low density lipoproteins) ....... ANSWER ........most
cholesterol in the blood is of this type. Often referred to as the bad
cholesterol. high levels in the blood increases the risk of fatty deposits
forming in the arteries, which in turn increases the risk of a heart
attack
Lipoproteins ....... ANSWER ........large molecules of fat and protein
in the bloodstream; how cholesterol is transported
Antioxidants ....... ANSWER ........slow the aging process. Reduce
cellular damage by binding with free radicals produced during
oxidation reactions
, Oxidation reactions ....... ANSWER ........the energy-yielding
reactions in which either an oxygen atom adds an electron to or a
hydrogen atom removes an electron from a substrate (a group of atoms
Page | 4 or molecule)—the net result is a substrate that has had a partial or
complete loss of a negatively charge particle, an electron. Two
partially charged atoms or groups of atoms, one positively charged and
the other negatively charged, now exist
Free radical (Oxidant) ....... ANSWER ........any atom or group of
atoms that has an unpaired electron. Because electrons typically
function in pairs, these are very prone to binding to other substrates in
an effort to regain this paired status. When this happens in the human
body, there is potential for a great deal of damage.
Carbohydrates ....... ANSWER ........produce 4 calories of energy per
gram. Found in foods as monosaccharides, disaccharides, and
polysaccharides. Sources include fruits, vegetables, pasta, and rice
which consist of simple sugars and starches
Protein ....... ANSWER ........produce 4 calories of energy per gram.
Sources include meats and milk. Composed of 8 essential (provided by
the diet) and 12 nonessential (synthesized by the body) amino acids.
Perform many functions including building cells and tissues, forming
blood and enzymes, and fighting infection.
means primary, and no organism can live, and almost no biological
process can take place, without it
