Answer to Question 1
Ans: A
Feedback:
The nurse should check the previous injection site before administering each insulin dose. The injection sites should be rotated to prevent lipodystrophy. Prefilled syringes should not be kept horizontally; they should be kept in a vertical or oblique position to avoid plugging the needle. The nurse checks for symptoms of myalgia or malaise when administration of metformin leads to lactic acidosis. Insulin should not be mixed with other drugs in the syringe. Some types of insulin may be combined in one syringe, but sterile water is never used.
Answer to Question 2
Ans: B
Feedback:
When administering insulin glargine to the client, the nurse should avoid mixing it with other insulins 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 the subcutaneous route 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 they are to be stored for about 3 months for later use.
