Ch 13: Altered Immune Response and Transplantation

4. An older adult patient who is having an annual check-up tells the nurse, "I feel fine, and I don't want to pay for all these unnecessary cancer screening tests!" Which information should the nurse plan to teach this patient? a. Consequences of aging on cell-mediated immunity b. Decrease in antibody production associated with aging c. Impact of poor nutrition on immune function in older people d. Incidence of cancer-associated infections in older individuals

ANS: A The primary impact of aging on immune function is on T cells, which are important for immune surveillance and tumor immunity. Antibody function is not affected as much by aging. Poor nutrition can also contribute to decreased immunity, but there is no evidence that it is a contributing factor for this patient. Although some types of cancer are associated with specific infections, this patient does not have an active infection.

1. The nurse provides discharge instructions to a patient who has an immune deficiency involving the T lymphocytes. Which health screening should the nurse include in the teaching plan for this patient? a. Screening for allergies b. Screening for malignancies c. Screening for antibody deficiencies d. Screening for autoimmune disorders

ANS: B Cell-mediated immunity is responsible for the recognition and destruction of cancer cells. Allergic reactions, autoimmune disorders, and antibody deficiencies are mediated primarily by B lymphocytes and humoral immunity

15. The nurse teaches a patient about drug therapy after a kidney transplant. Which statement by the patient would indicate a need for further instructions? a. "I need to be monitored closely for development of malignant tumors." b. "After a couple of years I will be able to stop taking the cyclosporine." c. "If I develop acute rejection episode, I will need additional types of drugs." d. "The drugs are combined to inhibit different ways the kidney can be rejected."

ANS: B Cyclosporine, a calcineurin inhibitor, will need to be continued for life. The other patient statements are accurate and indicate that no further teaching is necessary about those topics.

11. Which statement by a patient would alert the nurse to a risk for decreased immune function? a. "I had a chest x-ray 6 months ago." b. "I had my spleen removed after a car accident." c. "I take one baby aspirin every day to prevent stroke." d. "I usually eat eggs or meat for at least two meals a day."

ANS: B Splenectomy increases the risk for septicemia from bacterial infections. The patient's protein intake is good and should improve immune function. Daily aspirin use does not affect immune function. A chest x-ray does not have enough radiation to suppress immune function.

14. A patient seeks care in the emergency department after sharing needles for heroin injection with a friend who has hepatitis B. To provide immediate protection from infection, what medication will the nurse expect to administer? a. Corticosteroids c. Hepatitis B vaccine b. Gamma globulin d. Fresh frozen plasma

ANS: B The patient should first receive antibodies for hepatitis B from injection of gamma globulin. The hepatitis B vaccination series should be started to provide active immunity. Fresh frozen plasma and corticosteroids will not be effective in preventing hepatitis B in the patient.

12. Which patient should the nurse assess first? a. Patient with urticaria after receiving an IV antibiotic b. Patient who is sneezing after subcutaneous immunotherapy c. Patient who has graft-versus-host disease and severe diarrhea d. Patient with multiple chemical sensitivities who has muscle stiffness

ANS: B Sneezing after subcutaneous immunotherapy may indicate impending anaphylaxis and assessment and emergency measures should be initiated. The other patients also have findings that need assessment and intervention by the nurse, but do not have evidence of life-threatening complications.

16. An older adult patient has a prescription for cyclosporine following a kidney transplant. Which information in the patient's health history has implications for planning patient teaching about the medication at this time? a. The patient restricts salt to 2 grams per day. b. The patient eats green leafy vegetables daily. c. The patient drinks grapefruit juice every day. d. The patient drinks 3 to 4 quarts of fluid each day.

ANS: C Grapefruit juice can increase the toxicity of cyclosporine. The patient should be taught to avoid grapefruit juice. Normal fluid and sodium intake or eating green leafy vegetables will not affect cyclosporine levels or renal function.
