In developing a signage system for a health care clinic, the designer decides that the room identification signs should be mounted perpendicular to the wall near the door to each room. Whad would be of LEAST concern in the design work?
- A.
The color of the lettering and its background
- B.
The amount the Braille lettering is raised above the surface
- C.
Whether or not the width of the accessible route was reduced
- D.
The mounting height to the center of the sign
Correct Answer
A. The color of the lettering and its backgroundExplanation
The color of the lettering and its background is of least concern in the design work because the question states that the designer has already decided to mount the signs perpendicular to the wall near the door to each room. This suggests that the focus is on the placement and orientation of the signs rather than the color of the lettering and background. Therefore, the color of the lettering and its background would be of least concern in this particular design decision.Rate this question:

Which type of sink is best for barier-free design?
- A.
Vanity
- B.
Pedestal
- C.
Wall hung
- D.

- A.
Interior designer
- B.
Contractor
- C.
Subcontractor
- D.
Worker
Correct Answer

Which type of fee is most often disadvantageous to the interior designer?
- A.
Hourly rate
- B.
Multiple of direct personnel expense
- C.
Fixed fee
- D.
Retail method
Correct Answer
C. Fixed feeExplanation
A fixed fee is most often disadvantageous to the interior designer because it does not take into account the actual time and effort required for a project. If the designer underestimates the amount of work involved, they may end up working more hours than anticipated, resulting in a lower hourly rate. On the other hand, if they overestimate the work, they may end up earning less than they would with an hourly rate or multiple of direct personnel expense fee structure. Additionally, unexpected expenses or changes in the project scope can result in the designer receiving less compensation than they deserve.Rate this question:

Which type of fee is discouraged as a method of charging for professional services?
- A.
Hourly rate
- B.
Multiple of direct personnel expense
- C.
Fixed fee
- D.
Retail method
Correct Answer
D. Retail methodExplanation
The retail method is discouraged as a method of charging for professional services because it does not take into account the actual value or complexity of the services provided. Charging a fixed fee or an hourly rate allows for a more accurate reflection of the time, effort, and expertise required for the services. Similarly, using a multiple of direct personnel expense ensures that the fee is directly tied to the cost of providing the services. However, the retail method simply sets a fee based on the perceived market value, which may not accurately reflect the true value of the services.Rate this question:

A project construction budget prepared by the interior designer should probably NOT include
- A.
The contractor's profit
- B.
The designer's fees and reimbursables
- C.
Estimates for built-in equipment
- D.
Fixtures to be supplied by the owner
Correct Answer
B. The designer's fees and reimbursablesExplanation
The project construction budget prepared by the interior designer should not include the designer's fees and reimbursables because these costs are already accounted for in the designer's contract. The budget should only include costs that are directly related to the construction and installation of the project, such as the contractor's profit, estimates for built-in equipment, and fixtures to be supplied by the owner. Including the designer's fees and reimbursables in the budget would result in double-counting these costs and potentially lead to an inaccurate budget.Rate this question:

An interior designer could determine which clients have not paid by looking at the
- A.
Aged accounts receivable
- B.
Balance sheet
- C.
Cash flow statement
- D.
Income statement
Correct Answer
A. Aged accounts receivableExplanation
The aged accounts receivable is a report that shows the outstanding balances of customers and how long they have been overdue. By looking at this report, an interior designer can identify which clients have not paid their dues. The balance sheet provides a snapshot of a company's financial position, while the cash flow statement shows the movement of cash in and out of the business. The income statement reflects the company's revenues, expenses, and profits. None of these statements specifically highlight unpaid clients like the aged accounts receivable report does.Rate this question:

What type of insurance is LEAST necessary for a practicing interior designer?
- A.
Employee health
- B.
Worker's compensation
- C.
General liability
- D.
Automobile
Correct Answer
A. Employee healthExplanation
As a practicing interior designer, employee health insurance would be the least necessary type of insurance. This is because interior designers typically do not have employees working under them, so there would be no need for health insurance coverage for employees. Instead, the focus would be on insurances such as general liability to protect against any potential accidents or damages, worker's compensation to cover any injuries to themselves, and automobile insurance if they use a vehicle for work purposes. Therefore, employee health insurance is not necessary for a practicing interior designer.Rate this question:

- A.
Idemnification
- B.
Liquidated damages
- C.

The color of any object that people see is dependent upon the color of the object itself (option 1) and the color of the light striking it (option 4). The color of an object is determined by the wavelengths of light that it absorbs and reflects. When light strikes an object, it can be absorbed, transmitted, or reflected. The color that we perceive is the result of the wavelengths of light that are reflected back to our eyes. So, the color of the object and the color of the light are both factors that determine the color we see.Rate this question:
