Compare the nutritional value of egg white and egg yolks—ANSWER--Egg white is a high-
quality, fat-free source of protein; it is also a good source of niacin, riboflavin, potassium and
magnesium
Egg yolk contains all of the egg's fat; vitamins A, D, and E; and zinc; it also is a source of
cholesterol.
A patient's weight has decreased from 200 to 180 in the past 3 months. What is the percent
weight change?f—ANSWER--% Weight Change = Usual body weight (UBW) − Current
BW/UBW x 100
Patient: 200 − 180/200 x 100 = 10%
During the nutrition focused physical exam, you find that your patient has koilonychia, what
is the most likely cause of koilonychia and what nutrition strategy should be recommended
to the patient?—ANSWER--Koilonychia (spoon-shaped nails) may indicate that your patient
has a diet-related iron deficiency. Modifications should be made to the diet by increasing
iron through foods or supplementation.
When would a foodservice kitchen opt to use the L-shape variation of parallel design?—
ANSWER--A foodservice kitchen may be designed as an L-shape when there is insufficient
,space to use the back-to-back or face-to-face setup. The L-shape is well suited for accessing
several groups of equipment.
What is a convection oven?—ANSWER--In a convection oven, heat is transferred through hot
air circulated from a fan.
Describe fat-soluble vitamins in terms of absorption, transport, and storage—ANSWER--Fat-
soluble vitamins are absorbed like fat into the lymphatic system, then the blood. They must
travel with protein carriers and are stored in the liver or fatty tissue.
Describe water-soluble vitamins in terms of absorption, transport, and storage—ANSWER--
Water-soluble vitamins are absorbed directly into the blood. They travel freely throughout
the body; usually excess amounts are excreted through the kidneys.
Define intracellular water and extracellular water—ANSWER--Intracellular Water (ICW):
Water that's contained within the cell
Extracellular Water (ECW): The water in plasma, lymph, spinal fluid, secretion, and ICW
around and between the cells; accounts for 20% of body weight
What vitamin deficiency is a likely cause of night blindness?—ANSWER--Night blindness is
one of the first signs of vitamin A deficiency.
When is vitamin A intake a concern in pregnant women?—ANSWER--Vitamin A intake in
pregnant women is concerning when the vitamin A is preformed (ie, in supplement form).
Vitamin A intakes that exceed the tolerable upper limit can lead to congenital birth defects in
the eyes, skull, lungs, and heart.

, What are the DRI and tolerable upper intake level for vitamin A for adults?—ANSWER--DRI
for men: 900 mcg/day
DRI for women: 700 mcg/day, need more during lactation
UL: 3000 mcg/day or 10,000 IU
What is the tolerable upper intake level for vitamin D for adults?—ANSWER--Tolerable upper
intake level: 100 mcg (4000 IU)/day
What does 2% on a milk label indicate?—ANSWER--Milkfat is 2% of the total weight of the
milk
Identify the DRI and tolerable upper intake level for vitamin E for adults—ANSWER--DRI: 15
mg/day
UL: 1000 mg/day
Identify the DRI, deficiency symptoms, and toxicity for vitamin K—ANSWER--Men: 120
mcg/day
Women: 90 mcg/day
Vitamin K deficiency can cause bruising and abnormal bleeding due to its critical role in
blood clotting. Deficiency may also decrease bone density and, as a result, increase the risk
for osteoporosis.
For individuals taking anticoagulants, vitamin K toxicity can also block the effect of these
therapeutic medications. However, vitamin K toxicity is rare in healthy populations.
