A Client of a Domiciliary Nursing Agency Requires Vitamin B12

A client of a domiciliary nursing agency requires vitamin B12 injections every two weeks and insists on self-administration. The client is legally blind. The best way to assist this client is for the nurse to:

A) prefill syringes with the correct dose, so the client can use them for self-administration.
B) schedule the client's clinic appointments in accordance with the dosing schedule, then give the injection when the client is at the clinic.
C) teach the spouse to draw up the medication, then the client can give the injection.
D) make sure that the injection is scheduled during a visit so the nurse can supervise.
