MoCA Practice Test: Video 1 Answers (25 Questions) Flashcards

In the context of MoCA administration, what cognitive domain does the Clock Drawing task primarily assess?

Answer: Visuospatial and executive function

Clock Drawing probes visuospatial ability (constructing the circle and numbers) and executive function (planning hand placement).

A patient draws all 12 numbers but places them all on the right side of the clock face. Which scoring criterion is affected?

Answer: Numbers only

Crowding all numbers to one side violates the approximate correct position requirement for the numbers criterion.

What maximum score can a patient earn on the MoCA Clock Drawing subtest?

Answer: 3

The Clock Drawing subtest on the MoCA is worth a total of 3 points: contour, numbers, and hands.

Which cognitive process is most taxed when a patient must translate the verbal time '11:10' into correct hand positions on the drawn clock?

Answer: Abstract conceptual transformation and spatial planning

Converting a spoken time into spatial hand positions requires abstract conceptual processing (understanding clock conventions) and executive planning.

The MoCA manual states that the clock contour must be drawn 'without assistance.' What does this mean operationally?

Answer: The patient must draw freehand without a compass or template

The patient must draw the clock circle freehand; using a template, tracing, or compass would invalidate the constructional component of the task.

Why is performing simple arithmetic operations important in cognitive assessments?

Answer: It helps assess cognitive processing and memory functions.

Performing simple arithmetic operations requires several cognitive functions, including attention, working memory to hold numbers, and the ability to follow rules and sequences. Difficulties can indicate issues with these underlying cognitive processes, making it a valuable tool for assessing overall cognitive health. It provides insight into mental manipulation and processing speed.

Which of the following correctly continues the serial 7s sequence started at 100: 93, 86, ___?

Answer: 79

86 minus 7 equals 79, which is the next correct value in the sequence.

What total remains after subtracting 7 from 100 exactly four times?

Answer: 72

100-7=93, 93-7=86, 86-7=79, 79-7=72; four subtractions from 100 yield 72.

What is the importance of attention in performing calculations?

Answer: It ensures focus and reduces errors in calculations.

Attention is paramount for accurate calculation, as it allows an individual to focus on the numbers and operations, preventing distractions and careless mistakes. Sustained attention ensures that each step of a calculation is performed correctly and in the right sequence. Without adequate attention, even simple arithmetic can become error-prone.

A neuropsychologist adapts the MoCA for a patient with dyscalculia. Which accommodation is most consistent with standard MoCA guidelines?

Answer: Skip serial 7s and note the omission

Standard MoCA protocol does not have an official alternative for serial 7s; skipping and noting it preserves score integrity.

The MoCA abstraction subtest is most analogous to which classic neuropsychological concept?

Answer: Conceptual categorization / similarities subtest

The MoCA abstraction task mirrors the Similarities subtest used in Wechsler intelligence scales, assessing conceptual categorization.

A patient groups 'ruler and clock' as 'both have numbers.' How is this scored?

Answer: 0 points — concrete feature, not a category

Identifying a shared feature (numbers) rather than a superordinate category (measurement instruments) scores 0 points.

A patient scores 0 on both abstraction pairs. Which condition is LEAST likely to explain this finding?

Answer: Isolated peripheral neuropathy

Peripheral neuropathy affects the peripheral nervous system and would not impair cortical abstract reasoning as measured by the MoCA.

A clinician is explaining MoCA abstraction to a caregiver. Which description is MOST accurate?

Answer: The patient explains how two objects are similar in category

The abstraction subtest asks the patient to identify a categorical similarity between two presented word pairs.

Why is Abstract Thinking crucial for cognitive assessments?

Answer: It is a fundamental part of cognitive testing.

Abstract thinking is a key indicator of executive function and higher-order cognitive processing. Cognitive assessments like the MoCA include tasks requiring abstract thought (e.g., proverb interpretation, similarities) to evaluate a person's ability to conceptualize, reason, and shift mental sets. Deficits in this area can signal cognitive impairment.

A patient recalls 5 words spontaneously, then receives category cues and recalls 0 additional words. What is their Delayed Recall score?

Answer: 10 points

Five words recalled spontaneously × 2 points each = 10/10, the maximum possible score.

In the context of MoCA administration, what is an 'intrusion error' during Delayed Recall?

Answer: Reporting a word that was never on the original list

An intrusion error occurs when the patient reports a word not included in the original five-word list, potentially indicating confabulation or poor memory monitoring.

Which cuing condition in MoCA Delayed Recall does NOT contribute to the scored points but is recorded for clinical purposes?

Answer: Multiple-choice (recognition) recall

Multiple-choice recognition performance is recorded to aid differential diagnosis but earns 0 points toward the Delayed Recall score.

Which set of five words is used in the standard English MoCA Delayed Recall task?

Answer: Face, Velvet, Church, Daisy, Red

The five target words in the standard MoCA are Face, Velvet, Church, Daisy, and Red.

Which brain region is most critically linked to successful MoCA Delayed Recall performance?

Answer: Hippocampus and medial temporal lobe

The hippocampus and surrounding medial temporal lobe structures are essential for consolidating and retrieving episodic memories tested by delayed recall.
