Anurse is assigned to administer glargine to a patient at a health care facility. what precaution should the nurse take when administering glargine?

When administering glargine to the patient, the nurse should avoid mixing it with other insulin or solutions. It will precipitate in the syringe when mixed. If glargine is mixed with another solution, it will lose glucose control, resulting in decreased effectiveness of the insulin. Glargine is administered via SC once daily at bedtime. The nurse should not shake the vial vigorously before withdrawing insulin. The vial should be gently rotated between the palms of the hands and tilted gently end-to-end immediately before withdrawing the insulin. The nurse administers insulin from vials at room temperature. Vials are stored in the refrigerator if it is to be stored for about three months for later use.
