Rationales
1. The patient is exhibiting symptoms of organ transplant rejection which manifests as symptoms of organ failure. This type of rejection is associated with host verses graft disease in which the body is fighting the rejection.
2. Chronic stress can impair the immune response. While all the other responses are stressors on the body, they are not a result of chronic stress.
3. The patient is exhibiting symptoms of anaphylaxis likely as a result of the penicillin injection. Anaphylactic reactions are type I hypersensitivity reactions.
4. The exhaustion phase of the GAS occurs when coping mechanisms have been fully used up resulting in either the stressor being resolved or disease. Alarm is the body’s recognition of the stressor, and resistance is the initiation of coping mechanisms. Transference is not a stage of GAS.
5. Epinephrine produces much of the “fight-or-flight” symptoms. Insulin is not produced during this response and is not produced by the adrenal medulla. Cortisol is released during this response but by the adrenal cortex. Corticotropin is produced by the hypothalmus.
6. Histamine produces much of the inflammatory manifestations by dilating vessels. It is triggered by allergens, not inhibited by them. Constricting vessels would make them less permeable not more. Histamine is not stored in phagocyte skin cells.
7. Placental transfer is the only example of passive immunity because the infant is not actively creating antibodies, but it is borrowing the mothers. Immunizations and having the disease are examples of active immunity because the body actively forms antibodies when exposed to the vaccine or disease. Transplant rejection is not a form of immunity.
8. The body has lost the ability to distinguish self from non-self and begins to fight self in autoimmune conditions. Immunodeficiency is an ineffective immune response. Hypersensitivity and anaphylaxis are excessive immune reactions.
9. The 79 year old has 2 risk factors, advancing age and uncontrolled diabetes mellitus, and the other patients only have one.
10. The “first line of defense” is the skin and mucous membranes that provide a nonspecific barrier to keep all foreign substances out. A breach in the first line would be the presence of an indwelling catheter. A low WBC count, a “shift to the left”, and poor nutrition would give some indication of an issue with the second and third lines of defense.
11. The HIV infect and replicate in the CD4, which are T cells. The CD4s are destroyed in the process. With less CD4s the immune system is ill equipped to manage invasions. The other options do not occur with HIV.
12. The 58 year old woman has 2 firm risk factors, a chronic disease and a medication that impairs immune response. Her age may be a factor but not a strong one. A doesn’t have any risk factors. B has one, a chronic disease. With D, his age may be a weak risk factor, but the past medical condition should not be a significant factor.
13. The butterfly patterned rash across the face is a classic manifestation associated with SLE. The other options are not generally seen.
14. To be changed from HIV+ to a diagnosis of AIDS, requires a drop in the CD4 count to below 200 cells/mm3. The other options are not specific to AIDS.
15. Photosensitivity is a common manifestation of SLE, and sunbathing would worsen the condition. The patient will have to take medications even in the absence of symptoms. Infections are often a trigger for a exacerbation, and the patient is at increased risk for infection because they have a chronic disease and the medications often impair the immune reaction. Fever can be an indication of an infection.
16. Elevated erythryocyte sedimentation rate is the only systemic indicator of inflammation. The other manifestations are local.
