Question 3 of 5
During an outbreak in the hospital, all staff members were given immunoglobulin if they were not already immune to the disease. Which type of immunity will the staff who received the immunoglobulin have?
Correct Answer: D
Rationale: Passive immunity is the temporary resistance that has been donated to the host through transfusions of plasma proteins, immunoglobulins, or antitoxins, or transplacentally from mother to neonate. Passive immunity lasts only as long as these substances remain in the bloodstream. Active immunity is when the body produces its own antibodies against an antigen, from either infection with the pathogen or introduction of the pathogen in a vaccine.
Question 4 of 5
Which best describes the importance of discovering all of the variables that may be involved in creating a disease state in some persons?
Correct Answer: C
Rationale: Identifying risk factors is critical to creating or discovering specific prevention and intervention approaches that reduce chronic disease morbidity and mortality. Because some risk factors cannot be avoided, knowing other risk factors involved allows for more possibilities of preventing the problem. These variables need to be identified first so that health care providers are able to provide an explanation to persons as to why they are ill, obtain funding for research for the problem, and educate the community about the avoidance of the known risk factors.
Question 5 of 5
For which would a screening test be most appropriate?
Correct Answer: B
Rationale: It is extremely useful to the individuals concerned and society if screening can lead to early diagnosis and successful control of the disease process. There is no point in doing a screening if there is no treatment or if there is a known risk of social stigma and discrimination if it becomes known that the person has the disease. Discussion and disagreement continue as to whether genetic information should be used in family planning.
