ACNS Guidelines – CLTM QUESTIONS WITH COMPLETE SOLUTIONS

Sufficient storage space to allow for _______ hours of continuos video EEG monitoring is essential correct answer: 24 Perceived optical resolution is 525 line pairs, satisfactory for LTME, higher optical resolution of up to 1,000 line pairs available in some monitors correct answer: Monochrome Display Monitor Perceived optical resolution in 250 line paris, minimal acceptable standard for LTME. The current optimal standards are 1600 x 1200 pixels with a screen diagonal size of 20 inches or more correct answer: Color Display monitor Requires illumination of 0.5 footcandle, satisfactory for daylight monitoring conditions, unsatisfactory for nocturnal monitoring under reduced lighting conditions. correct answer: Standard monochrome (black and white) Allows monitoring in only 0.03 footcandles of illumination, particularly sensitive to red light, useful for nocturnal monitoring under reduced lighting conditions, automatic iris need to compensate for sudden increases in light level correct answer: Low light level monochrome Effective in as little as 0. footcandles of illumination, image intensifier technology, high resolution for nocturnal monitoring, expense is substantial, value for increased resolution not established correct answer: Silicon intensified (Starlight) Can be used for nocturnal monitoring with small night light, increased expense, value not established in nocturnal conditions except to attempt exlusive use of color cameras. correct answer: Low-light level color Longer lasting than tube cameras, good resolution, no "blooming" and no image retention ("burn in"), tolerates difficult lighting conditions, is available with built-in infrared
