Chapter 33 : Introduction to the Immune System Questions
Question 1 of 5
Why would it be important for the nurse to question the client about sexual practices, history of substance use disorder, and lifestyle during the interview process?
Correct Answer: B
Rationale: The nurse investigates the client's allergy history and asks about practices that put the client at risk for AIDS. The interview will not determine the client's ability to be compliant. The physician would make the determination if a counseling referral should be made. It is irrelevant to determine the personality traits in the initial interview.
Question 2 of 5
A client asks the nurse about the importance of taking supplements to maximize immune function. The client is healthy and does not have any medical problems. What is the best information to give to the client?
Correct Answer: D
Rationale: Until more is known about nutrient interactions, the best dietary advice to maximize immune function in healthy people is to eat a moderate diet that is balanced and varied. Eating fruits and vegetables and a vegetarian lifestyle may be healthy choices but do not maximize immune function as a balanced diet will.
Question 3 of 5
The nurse is administering a skin test for detection of exposure to tuberculosis. How would the nurse determine if the client was exposed to tuberculosis?
Correct Answer: B
Rationale: The injection area swells if the client has developed antibodies against the antigen. The client is not necessarily actively infectious if the test results are positive. Although a productive cough is one of the symptoms of active tuberculosis, it may also indicate other diseases and disorders. The area should not be painful, and the client should not break out with a rash.
Question 4 of 5
A client is admitted to the hospital with a diagnosis of pneumonia. The client informs the nurse of having several drug allergies. The physician has ordered an antibiotic as well as several other medications for cough and fever. What should the nurse do prior to administering the medications?
Correct Answer: C
Rationale: Clear identification of any substances to which the client is allergic is essential. The nurse must consult drug references to verify that prescribed medications do not contain substances to which the client is hypersensitive. Administering the medications or giving one at a time may cause the client to have an allergic reaction. The nurse may call the pharmacy but still maintains responsibility for the medications administered.
Question 5 of 5
What type of immunoglobulin does the nurse recognize that promotes the release of vasoactive chemicals such as histamine when a client is having an allergic reaction?
Correct Answer: D
Rationale: IgE promotes the release of vasoactive chemicals such as histamine and bradykinin in allergic, hypersensitivity, and inflammatory reactions. IgG neutralizes bacterial toxins and accelerates phagocytosis. IgA interferes with the entry of pathogens through exposed structures or pathways. IgM agglutinates antigens and lyses cell walls.
