The MoCA serial 7s subtraction task is primarily designed to assess which cognitive domain?
Answer: Attention and working memory
The serial 7s task targets attention and working memory by requiring sustained mental calculation.
A patient scores 1 out of 3 on the MoCA serial 7s. How many of the five subtractions did the patient answer correctly?
Answer: Exactly 1
MoCA scoring: 1 correct = 1 point, 2–3 correct = 2 points, 4–5 correct = 3 points.
What is the correct result of subtracting 7 from 79?
Answer: 72
79 minus 7 equals 72, which is the fourth step in the serial 7s sequence from 100.
In the MoCA serial 7s task, the examiner says 'subtract 7' five times starting at 100. What is the fifth (final) expected answer?
Answer: 65
The sequence is 93, 86, 79, 72, 65; the fifth subtraction results in 65.
Which condition would most directly impair a patient's ability to complete the MoCA serial 7s task?
Answer: Working memory impairment
Working memory is essential for holding intermediate results during sequential subtraction.
On the MoCA, the serial 7s task contributes a maximum of how many points to the total possible score of 30?
Answer: 3 points
The serial 7s subtraction task is worth a maximum of 3 points on the 30-point MoCA scale.
A patient answers the serial 7s as: 93, 86, 80, 73, 66. How many subtractions were correct?
Answer: 2
Only 93 and 86 are correct; 80 should be 79, and subsequent answers inherit the error, so only 2 are correct.
