ASU BME100 MIDTERM

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. De�ning 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 speci�es 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 veri�cation activity?

Choices:

1) Con�rming that users prefer the device color 2) Testing whether the prototype meets a speci�ed 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 speci�ed battery-life requirement Explanation: Veri�cation asks whether the design was built to speci�cation. Measuring battery life against a stated requirement directly checks a design speci�cation.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 speci�ed resistor value 2) Con�rming that the �nal device addresses the intended user need in its use environment 3) Measuring whether a drawing has the speci�ed dimensions 4) Reviewing whether a part number matches the bill of materials Correct Answer: Con�rming 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 speci�cations.Page 3
