What is the name for the active form of vitamin D? - 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 - 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 - 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 - 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.

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 - ANSWER-Diarrhea
The elderly are considered individuals over 65 years of age and are categorized as
young old (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.
Diarrhea is not a common nutrition problem; rather, constipation is more common due to
decreased gastric mobility and decreased HCl stomach secretion in the elderly.
Which manager reflects a systems approach to management?
Ted, who formally organizes and administers his employees' work in a scholar principle
Maggie, who considers the external and internal factors before making a decision
Martina, who tells her employees that everyone will be involved in decisions and that
they are the keys to the company's productivity
Jeff, who inspires employees to become leaders and to motivate each other towards the
group mission - ANSWER-Correct answer: Maggie, who considers the external and
internal factors before making a decision
, Maggie uses a systems approach by considering both the external and internal
environments that can impact her company before making a decision or allocating
resources.
Ted uses a traditional or classical approach by administering work in a scalar principle,
where authority and responsibility flow in a one-way direction from high to low.
Martha uses a human relations or Theory Z approach by preaching to her employees
that everyone is involved in the decision-making process and that employee
involvement is the key to productivity.
Jeff uses a transformational management style where he uses activities to transform
inputs to outputs to link, manage, and build functional systems by inspiring agents of
change.
Greg is a marathon runner who weighs 63 kilograms and is 65 inches tall. During his
last marathon, he lost 3.5 pounds of sweat. How much fluid should he have drunk
during the race?
84 oz
56 oz
63 oz
3.5oz - ANSWER-Correct answer: 56 oz.
During endurance exercise, athletes should replace 100% of fluids lost during moderate
to vigorous activity. For example, Greg lost 3.5 pounds (3.5 pounds = 56 ounces) so he
should have drunk 56 oz. of fluid to replace 100% of his loss. The amount of fluids
required during exercise can increase for high heat, high altitude, and/or high humidity
situations.
After endurance exercise, athletes should replace 100-150% of fluids lost during
moderate to vigorous activity with carbohydrates and electrolytes (Na) to rehydrate. For
example, Greg lost 3.5 pounds during exercise so he should drink 84 oz. to replace
150% of his losses (3.5 pounds = 56 ounces x 1.5 = 84 oz.).
According to the ADA, which of the following is a "reasonable accommodation" to make
a workplace and dining area accessible to a person with disabilities?

The Americans with Disabilities Act (ADA) went into effect in 1994 for companies with
15 or more employees. It provides general guidelines for implementing reasonable
accommodations for persons with disabilities in the workplace and dining areas.
Accommodations may include installing ramps, widening doorways, and lowing shelves
and counters.
