What is the name for the active form of vitamin D? - correct answer ✔✔ Calcitriol
Calcitriol, also called 1,25-dihydroxycholecalciferol or 1,25-dihydroxyvitamin D3, is the active
form of vitamin D.
Vitamin D can be absorbed and metabolized through sunlight and/or dietary intake. Cholesterol
is a precursor for vitamin D metabolism.
To metabolize vitamin D by sunlight, first our skin absorbs previtamin D in the form of 7-
dehydrocholestrol to become precalciferol (previtamin D3). Thermal isomerization occurs to
produce cholecalciferol (vitamin D3). Cholecalciferol is the form of vitamin D found in animal
food products.
Then, cholecalciferol goes to the liver and converts to 25-OH-D3 (calcidiol), which is the storage
form of vitamin D. This form travels to the kidneys to become 1,25-OH2-D3 (calcitriol), which is
the active form of vitamin D.
A restaurant has decided to change its name to either Jane's Steakhouse or The Texas Steak
House. The CEO is hosting a vote on the new name and will be accepting the majority decision.
What type of leadership style is this?
Democratic
consensus
Autocratic
Participative - correct answer ✔✔ Democratic
Leadership styles and techniques reflect the personality of the management. The democratic
style accepts the majority decision.
The consensus style requires the entire group to come to an agreement. For example, the CEO
might require everyone to meet and discuss until they all agree on which restaurant name to go
with.
,The participative style seeks input from and shares power with employees. A participative CEO
might have used this method to brainstorm ideas for the new name with the employees.
The autocratic style takes control, makes decisions, and assumes full responsibility. An
autocratic CEO would choose the new restaurant's name on his own without input from the
employees.
A manager performs in a decisional role when committing an organization to a specific course of
action or strategy. Whose management theory is this an example of?
Taylor's Scientific Management
Mintzberg's Management Roles
Katz's Skills Management
Drucker's Management by Objectives - correct answer ✔✔ Mintzberg's Management Roles
Mintzberg's Management Roles argued there are ten primary roles that can be used to
categorize a manager's different functions to accomplish work and use skills.
Katz's Skill Management identified three managerial skills essential to successful management:
technical, human, and conceptual.
Drucker's Management by Objectives (MBO) is the process of defining specific objectives within
an organization that management can convey to organization members, then deciding how to
achieve each objective in sequence.
Taylor's Scientific Management is a theory that analyzes and synthesizes workflows, with the
main objective being to improve economic efficiency, especially labor productivity.

What can be inferred about a patient with a HgbA1C of 5.7%?
T2DM
Prediabetic
T1DM
GDM - correct answer ✔✔ Prediabetic
Prediabetes is indicated by an HgbA1C of 5.7-6.4, which puts a patient at risk for developing
diabetes.
Diabetes (T1DM/T2DM) is diagnosed by a fasting plasma glucose of ≥126 mg/dL, a glucose
tolerance test of ≥200 mg/dL, or an HgbA1C of ≥ 6.5%.
Gestational diabetes (GDM) is diagnosed at 24-28 weeks of gestation with a glucose tolerance
test of ≥140mg/dL to indicate further testing.
Using the chart below and the moving average model, determine the second forecast for the
seven-day moving average.

The moving average model is a time series method of forecasting where a group of past records
are averaged and used as the forecast. The next forecast (second) is calculated by dropping the
first number and adding the next.
To solve for the second forecast (total of days 2 through 8): 54+60+56+53+63+69+62 = =

Which of the following nutritional problems is not common in the elderly?
polypharmacy
sore mouth
hypercholesterolemia
diarrhea - correct answer ✔✔ Diarrhea

(65-74), aged (75-84), and oldest old (>85), according to the US Census Bureau. Common
nutritional problems for the elderly include sore mouth, polypharmacy, chronic disease, protein
energy malnutrition, decreased absorption, hypercholesterolemia, and tooth loss.
