PRACTICE EXAM
Question 1: Which statement best describes biomedical engineering?
Choices:
1) Applying engineering principles to problems in biology and medicine 2) Studying only the chemical synthesis of pharmaceutical compounds 3) Diagnosing disease independently of physicians 4) Manufacturing consumer electronics without health applications Correct Answer: Applying engineering principles to problems in biology and medicine Explanation: Biomedical engineering integrates engineering with biology and medicine to analyze physiological systems and develop technologies such as devices, diagnostics, biomaterials, and therapies.Page 1
Question 2: A team is beginning a project to improve mobility for patients with
limited hand strength. What should the team do rst in a needs-driven design process?
Choices:
1) Select a material for the nal product 2) Identify and characterize the unmet user need 3) Write a marketing slogan 4) Begin manufacturing the rst design concept
Correct Answer: Identify and characterize the unmet user need
Explanation: Needs-driven design begins by understanding the clinical or user problem before choosing a solution. Dening the need helps prevent premature commitment to an unsuitable design.
Question 3: Why is it important to distinguish a need statement from a solution
statement?
Choices:
1) A need statement species the nal device geometry 2) A need statement keeps the problem open to multiple possible solutions 3) A solution statement is always required before user observation 4) A solution statement eliminates the need for design constraints Correct Answer: A need statement keeps the problem open to multiple possible solutions Explanation: A well-formed need statement describes the problem and desired outcome without locking the team into one device or method, preserving room for multiple concepts.Page 2
Question 4: A design requirement states that a wearable monitor must operate for at least 12 hours per charge. Which test is a verication activity?
Choices:
1) Conrming that users prefer the device color 2) Testing whether the prototype meets a specied battery-life requirement 3) Determining whether the device improves the intended clinical outcome 4) Estimating the market size for the device Correct Answer: Testing whether the prototype meets a specied battery-life requirement Explanation: Verication asks whether the design was built to specication. Measuring battery life against a stated requirement directly checks a design specication.Question 5: After technical requirements are met, a team evaluates the device with intended users in the expected use setting. What is this evaluation primarily assessing?
Choices:
1) Checking whether a circuit uses the specied resistor value 2) Conrming that the nal device addresses the intended user need in its use environment 3) Measuring whether a drawing has the specied dimensions 4) Reviewing whether a part number matches the bill of materials Correct Answer: Conrming that the nal device addresses the intended user need in its use environment Explanation: Validation asks whether the team built the right product for the intended users and purpose. It focuses on satisfying the real-world need rather than merely meeting component specications.Page 3
