Which stock rotation methods are used to minimize the risk of using expired or outdated materials? (Choose two) Response:

The correct answer is A. First-in/first-out (FIFO) C. First-expired/first-out (FEFO). FIFO (A) and FEFO (C) are correct because both methods prioritize using older or sooner-expiring stock first, directly reducing the chance that materials sit unused until they expire. FIFO rotates stock by receipt date - the oldest items entered are used first - while FEFO goes…

Explanation

FIFO (A) and FEFO (C) are correct because both methods prioritize using older or sooner-expiring stock first, directly reducing the chance that materials sit unused until they expire. FIFO rotates stock by receipt date - the oldest items entered are used first - while FEFO goes further by sorting specifically by expiration date, making it especially valuable for perishables or pharmaceuticals where items received later may actually expire sooner.

LIFO (B) is wrong because it does the opposite: the newest stock is used first, leaving older items to sit longer and potentially expire. MEFO (D) is a distractor - it prioritizes cost over freshness, which has nothing to do with preventing expiration.

Memory tip: Think of the "F" in FIFO and FEFO as standing for "Fresh out first" - both keep old/expiring stock from getting buried. If you see an answer about expiry risk, FEFO is your precision tool (it uses expiration dates directly), while FIFO is the general-purpose rotation standard.
