It was very great to know that your internships are going on in the hospital and now I can understand that you have direct contact with patient also so you can better understand than me that intravenous way of giving medicine to your patient is more effective than to give oral medications because most of the time many patient bodies are unable to absorb particular medicine so IV route is best.

Agree with you that intra muscular injections are more easy to use that's why it is your preference I wish you good luck in this engagement challenge in which you put your reasonable efforts to participate.
