Which of the following clients is at the greatest risk for developing an intracellular pathogen infection?
A. Hyperthyroid client who has received treatment with radioactive iodine
B. A breast cancer client who has a WBC count of 8000
C. A teenager who attends a crowded high school
D. An aids client with a decreased CD4 + TH1 count
An AIDS client with a decreased CD4+ TH1 count
Explanation:
Thus, the CD4+ TH1 cell controls and coordinates host defenses against certain intracellular pathogens, a function that helps to explain why a decreased CD4+ TH1 count in persons with acquired immunodeficiency syndrome (AIDS) places them at high risk for intracellular pathogen infections. If the teenager has a healthy immune system, high school should not place him or her at high risk for infection. A WBC of 8000 is normal. Radioactive iodine attacks the thyroid gland and does not usually interfere with immunity.
