Nursing

Hypothetically, I got injured by the needle during cleaning the room of the patient who suffers from Hepatitis B and C and also an HIV (human immuno deficiency virus) positive patient. The needle must have been in contact with the blood of the patient and there are chances that my blood may also have picked up the antigen from the needle. Thus, the rationale for hepatitis B testing is the chances of infection through the needle.

The comparison of cell mediated and humoral immunity by an antigen is as follows: • In both of the mentioned cases; that is cell-mediated immunity and humoral immunity; the body fight in each case though in a different manner. The respective cells then fight against the cause of the disease that is antigen or a toxin. The contrasting features of cell-mediated immunity and humoral immunity are as follows: • In case of cell-mediated immunity, the T-cells are responsiblefor the formation of antibodies; while in case of humoral immunity, B-cells form antibodies. • The cell-mediated immunity works in case of entrance viruses, bacteria, parasites and it kills tumor cells. The humoral immunity works in case of toxins released by bacteria and viruses that cause disease and in case of viral infections. • Antibodies are not formed in case of cell-mediated immunity but are formed in case of humoral immunity.

Immunization is the process of administering dead or live (weakened) microorganisms of a disease into the body of an individual do as to start an immune response. The body will then recognize the microorganisms or antigen and then form antibodies which will fight against the infection by that particular antigen. The rationale behind giving immunization is development of antibodies in the body because first time antibody formation is slow and the subsequent antibody formation is fast as compared to first time. The information that should be obtained from Abbotts about Samantha's first response is as follows: • If the child had fever up to 105°F. • If the child had non-stop crying for more than 3 hours on the day of vaccination. • If the child had got collapsed on the day of vaccination. • If there was any life threatening allergy to child on or after the days when the child got the vaccination.
