If the informatics nurse is concerned that a computer system may not function well during peak times of access, the type of testing needed is:

• A. functional testing
• B. black box testing
• C. system integration testing
• D. load/volume testing

Answer: (D)

Evaluating system performance under peak demand. When a system may be accessed by many users at once, you need to see how it behaves under heavy load and large data volumes. This kind of testing, often called load/volume testing, simulates high concurrency and data volume to measure response times, throughput, resource usage, and stability. It helps determine if the system will still perform acceptably during busy periods and identifies bottlenecks before going live. This isn’t about whether individual features work (functional testing) or about internal implementation or interfaces (system integration or black box testing). It’s specifically about performance and capacity under peak conditions, which is why it’s the best fit for concerns about functioning well during peak times.
