A patient tells the nurse that it seems like the only time she gets a cold is when she is under higher than normal stress. The reason for the patient having colds is because of
1. cortisol suppressing the immune system and decreasing T and B cell response.
2. an inadequate intake of nutrients during periods of stress.
3. lack of rest and sleep.
4. an increase in T and B cell production leading to an autoimmune response.
1
Rationale: Cortisol has a direct suppressing effect on the immune system by inhibiting the production of interleukins which stimulate T and B cell production and response. There is no evidence to suggest that the patient has an inadequate intake of nutrients during periods of stress. There is also no evidence to support the patient is lacking sleep or rest. Cortisol suppresses T and B cell production and response and does not increase them.
