The singular factor that makes nursing to be different from all other profession is that nurses put the life of others before theirs. This means they have to endure emotional and physical pains of mind and body. For example, nurses have to give up their comfort and time to be by the side of patients, hence miss important appointments with friends.
No matter how empathetic you may be towards your patients, there are times when a nurse has to be brutal with the truth. Though what every patient wants to hear is that they are getting better but when the patients are never going to get better (like a case of malignant cancer), it will be in the best interest of the nurse to let them know.
