Question

Difficulty: easy. Skill: recognize. 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 efficiency measurement? The case file includes 4 recent sessions, 4 implementers, and 1 setting.

A
Rely on caregiver's report alone and stop collecting direct evidence
B
Change the intervention immediately based on the concern alone
C
Continue unchanged and ignore the new contextual information
D
Choose the measurement system that matches the behavior dimension and decision question in relation to client's repeating questions after instructions

Correct answer

Explanation

Answer D

The clue is the combination of parent report that conflicts with recent session data, repeating questions after instructions, and the required task: Efficiency measurement. The case file includes 4 recent sessions, 4 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

Clue
Key scenario clue

The clue is the combination of parent report that conflicts with recent session data, repeating questions after instructions, and the required task: Efficiency measurement. The case file includes 4 recent sessions, 4 implementers, and 1 setting.

Trap
Common trap

Stakeholder input matters, but direct data, context, and integrity checks are still needed for a defensible answer.

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

Stakeholder input matters, but direct data, context, and integrity checks are still needed for a defensible answer.

B
Choice B

This is weaker because it skips the assessment, integrity, or decision rule needed before changing procedures.

C
Choice C

Ignoring relevant data or context prevents a defensible behavior-analytic decision.
