Immune System Drugs Questions
Question 1 of 5
A patient who is receiving an immune suppressant has been admitted to the unit. What would be a priority action by the nurse?
Correct Answer: C
Rationale: The correct answer is C: Protect the patient from exposure to infection. This is the priority action because immune suppressants weaken the immune system, making the patient more susceptible to infections. By protecting the patient from exposure to infection, the nurse can prevent potential complications and promote the patient's safety. Monitoring nutritional status (A) is important but not as critical as preventing infections. Patient teaching (B) and providing support for adverse effects (D) can be addressed after ensuring the patient's safety from infections.
Question 2 of 5
How do immune suppressants work when ordered for a patient who has had an organ transplant?
Correct Answer: A
Rationale: The correct answer is A: Blocking normal effects of the immune system. Immune suppressants are prescribed post-organ transplant to prevent rejection by inhibiting the immune system's response against the new organ. By blocking the immune system's normal function, these medications help maintain the transplanted organ's viability. Explanation for incorrect choices: B: Stimulating the immune system to fight off infection contradicts the purpose of immune suppressants, which aim to dampen the immune response. C: Working with corticosteroids to enhance healing is not the primary mechanism of action of immune suppressants. D: Working with corticosteroids to promote suppressor cells is not accurate as immune suppressants primarily target different pathways compared to corticosteroids.
Question 3 of 5
The nurse admits a patient who was newly diagnosed with Kaposi's sarcoma to the unit. The physician has ordered an IV infusion of an interferon. What drug would be appropriate?
Correct Answer: C
Rationale: The correct answer is C: Interferon alfa 2b. This is the appropriate drug for Kaposi's sarcoma treatment due to its antiviral and immunomodulatory properties. Interferon alfa 2b is commonly used in the treatment of this condition. Interferon beta1a (A) is used for multiple sclerosis, not Kaposi's sarcoma. Interferon gamma 1b (B) is mainly used for chronic granulomatous disease. Peginterferon alfa 2b (D) is used for hepatitis C treatment, not Kaposi's sarcoma. Therefore, the correct choice is Interferon alfa 2b for this patient.
Question 4 of 5
What monoclonal antibody is used to prevent respiratory syncytial virus (RSV) in high-risk children?
Correct Answer: A
Rationale: The correct answer is A: Palivizumab. Palivizumab is specifically designed to prevent RSV in high-risk children by targeting the virus. Natalizumab is used for multiple sclerosis, Belimumab for lupus, and Eculizumab for paroxysmal nocturnal hemoglobinuria. These choices are incorrect as they do not target RSV.
Question 5 of 5
The pharmacology instructor is explaining interleukins to the class. What would be the best definition of interleukins?
Correct Answer: C
Rationale: Rationale for choice C: Interleukins are chemicals that facilitate communication between leukocytes, aiding in the stimulation of immunity. This is accurate because interleukins play a crucial role in regulating immune responses and coordinating interactions between different immune cells. They help in the activation, proliferation, and differentiation of leukocytes, thereby enhancing the body's immune defense mechanisms. Summary of other choices: A: Incorrect. Interleukins are not specifically related to responses against viral infections, but rather play a broader role in immune regulation. B: Incorrect. Interleukins generally do not block inflammatory reactions; instead, they often promote immune responses. D: Incorrect. While interleukins do bind to specific receptors, their functions are not limited to responding to very specific situations, but rather involve broader immune regulation.
