Immune System Drugs Questions
Question 1 of 5
The health care provider plans to inject an interferon directly into the patient's wart. What interferon will the nurse prepare?
Correct Answer: C
Rationale: Rationale: The correct answer is C, Interferon alfa n3 (Alferon N), because it is specifically approved for the treatment of warts caused by human papillomavirus (HPV). Alferon N has been shown to have antiviral activity against HPV, making it the most suitable choice for injecting directly into the wart. Interferon alfa 2a (A), Interferon alfacon 1 (B), and Interferon beta 1a (D) are not specifically indicated for the treatment of warts caused by HPV, making them incorrect choices for this scenario.
Question 2 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 3 of 5
A 70-year-old patient with acute myelocytic leukemia is receiving sargramostim (Leukine). What is a priority nursing action for this patient?
Correct Answer: B
Rationale: The correct answer is B: Increasing fluids. In a patient with acute myelocytic leukemia receiving sargramostim, hydration is crucial to prevent dehydration and maintain renal function due to the potential for increased urine output. Adequate fluids help prevent complications such as renal impairment and electrolyte imbalances. Providing a quiet environment (A) can be beneficial but not the priority. Comfort measures for nausea (C) are important but do not address the immediate need for hydration. Encouraging appropriate dietary intake (D) is important but not as critical as ensuring adequate fluid intake in this scenario.
Question 4 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 5 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.
