1) A young girl requires a liver
transplant due to failure of her liver to function. What is required for her to have a good prognosis and why?
The ABO and other blood group antigens of the donor and recipient must be determined. Next, the donor/ recipient tissues are matched as closely as possible. After surgery she must receive immunosuppressive therapy to keep her body from rejecting the new liver as foreign tissue.
2) A physician orders Tylenol for a
temperature greater than 101 degrees F. The patient's temperature is 100.4 F. Explain the rationale for not medicating a fever of 100.4 F.
A mild or moderate fever is an adaptive response that seems to benefit the body. Bacteria need large amounts of zinc and iron to multiply. During fever, the liver and spleen make them less avilable which helps reduce the bacterial population.
3) Nursing care of a patient with
acquired immune deficiency syndrome (AIDS) includes monitoring of T lymphocyte counts. Explain why.
The primary defect in patents with AIDS is depletion of helper T cells, and therefore the cell- mediated response. This immunodeficiency makes the patient more susceptible to infection and unusual cancers.
4) When the white blood cell count is
depressed, the classic signs of infection such as redness, heat, and swelling are not manifested. In this case, the nurse should avoid administering aspirin. Explain why.
Aspirin would disguise a fever that would indicate infection.
