Administering of Medicines to the Patient

I learned the proper way of administering the medicines to the patient and the right medicine for them. by doing the proper way of administering the medicine, the patient can properly recover because he has taken the proper medicine and took the proper medicine properly. I also learned the proper medicine when it is taken from the mouth, the medicines are supposed to be capsules or in tablets. when the medicine is being taken from the outer skin, he/she must use creams, lotions or ointments.when it is in the eyes,ears or nose, you must take drops like eye drops or ear drops and nasal and so on. I also learned that doctors used codes in prescribing the time intervals to observe in the administration of medicine and these are the following:
                                          qd- once a day                                bid-twice a day
                                           tid- thrice a day                               qid- four times a day
                                          ac- before meals                              q4h- every 4 hours
and so on.
I guess you can say that I learned a lot from this lesson and it can help me a lot in my way of taking care of people.
