What instruction is given for the handling of insulin regarding temperature?

  1. Only store at room temperature

  2. Freeze before use

  3. Do not freeze

  4. Keep in direct sunlight

The correct answer is: Do not freeze

Insulin is a temperature-sensitive medication, and therefore it should not be frozen. Freezing can cause the insulin to become ineffective, resulting in improper blood glucose control. Storing insulin at room temperature is recommended, as it maintains its effectiveness and is easier to administer. Freezing the insulin before use is unnecessary and could potentially lead to dosing errors. Keeping insulin in direct sunlight can also have negative effects, as exposure to heat and light can cause it to break down and become ineffective. Therefore, the correct instruction for handling insulin in regards to temperature is to avoid freezing it.
