Correct answer: D — Keep spare pens refrigerated and protect in-use pens from heat

Insulin should be protected from extremes of temperature. Unopened supplies usually require refrigeration, while in-use pens may be kept at room temperature for a product-specific period. Heat can reduce potency and should be avoided.
