Question

Difficulty: medium. Skill: apply. Type: data interpretation.

The team must choose how to measure and interpret repeating questions after instructions in a telehealth caregiver meeting. Which option best fits operational definitions? The case file includes 9 recent sessions, 3 implementers, and 1 setting.

A
Send the written protocol again without observing performance
B
Choose the measurement system that matches the behavior dimension and decision question in relation to client's repeating questions after instructions

Correct answer

C
Proceed informally because the team believes the action will help
D
Tell everyone to try harder and review the case next month

Explanation

Answer B

The clue is the combination of parent report that conflicts with recent session data, repeating questions after instructions, and the required task: Operational definitions. The case file includes 9 recent sessions, 3 implementers, and 1 setting. Choose the measurement system that matches the behavior dimension and decision question in relation to client's repeating questions after instructions is best because it answers that clue through measurement system selection instead of treating the scenario as a generic behavior problem. On exam items like this, name the decision point first, then eliminate options that rely on one report, a label, a familiar protocol, or an action that skips the relevant data check.

Why this question is hard

The clue is the combination of parent report that conflicts with recent session data, repeating questions after instructions, and the required task: Operational definitions. The case file includes 9 recent sessions, 3 implementers, and 1 setting.

Trap
Common trap

Written directions alone do not verify performance or correct implementation errors.

Next
If you missed it, review Measurement system selection

Then answer a few related scenarios before moving back to broad practice.

Why the other choices are weaker

A
Choice A

Written directions alone do not verify performance or correct implementation errors.

C
Choice C

Good intent does not replace consent, documentation, competence, or other safeguards.

D
Choice D

Vague delayed feedback does not create a measurable plan for improvement.
