Immune System Medication Questions
Question 1 of 5
A 30-year-old woman has been diagnosed with leukemia and will be using an immune modulator for treatment. What will be important to discuss with the patient when the nurse provides patient teaching about her treatment?
Correct Answer: B
Rationale: The correct answer is B: The need to use barrier contraceptives while taking the drug. This is important because immune modulators can have teratogenic effects, meaning they can harm a developing fetus. Using barrier contraceptives can help prevent pregnancy and protect the fetus from potential harm. Choice A is incorrect because continuing oral contraceptives may not provide adequate protection against pregnancy while on immune modulators. Choice C is incorrect as avoiding sexual intercourse is not necessary as long as effective contraception is used. Choice D is incorrect as taking aspirin daily is not related to the use of immune modulators and may not decrease adverse effects.
Question 2 of 5
A nurse is discussing interferon alfa 2b with a patient. What will the nurse encourage the patient to do while taking this drug?
Correct Answer: A
Rationale: The correct answer is A: To avoid crowds. Interferon alfa 2b can weaken the immune system, making the patient more susceptible to infections. Avoiding crowds helps reduce the risk of exposure to pathogens. B, increasing salt intake, is incorrect as it is not a recommended action for patients taking interferon alfa 2b. C, decreasing milk intake, is also incorrect as there is no evidence to suggest that milk consumption interferes with the effectiveness of this medication. D, eating three meals a day, is irrelevant to the action needed to manage the side effects of interferon alfa 2b.
Question 3 of 5
While studying for a pharmacology test, a student asks his peers about interferons. What statement about interferons is accurate?
Correct Answer: D
Rationale: Interferons are proteins released by cells in response to viral infections. Choice D is correct because interferons interfere with viral replication within infected cells by activating antiviral proteins. Choices A, B, and C are incorrect because interferons do not stimulate B-lymphocyte activity, interfere with stem cell multiplication, or stimulate growth and differentiation of lymphocytes. Interferons primarily function as part of the innate immune response to combat viral infections.
Question 4 of 5
A patient has just been told that her cancer has metastasized to her right kidney. An interferon (Aldesleukin) has been prescribed to treat this metastasis. The patient asks why this interferon is ordered. What is the nurse's best response?
Correct Answer: B
Rationale: The correct answer is B: It activates human cellular immunity and inhibits tumor growth. Rationale: 1. Interferon (Aldesleukin) is known to activate the immune system, particularly cellular immunity. 2. By activating cellular immunity, interferon helps the body to recognize and attack tumor cells, inhibiting tumor growth. 3. This mechanism is crucial in fighting metastatic cancer, such as in the patient's case. 4. The other options are incorrect because interferon does not protect autologous tumor cells (A), enhance allogeneic stem-cell transplantation (C), or have a direct proliferative effect on renal tumors (D).
Question 5 of 5
The nursing class is studying monoclonal antibodies. What monoclonal antibody reacts to human T cells, disabling them and acting as an immune suppressor?
Correct Answer: D
Rationale: The correct answer is D, Muromonab-CD3. This monoclonal antibody specifically targets and reacts with human T cells, disabling them and acting as an immune suppressor. Muromonab-CD3 is used in conditions where T cells need to be suppressed, such as in transplant rejection. A: Adalimumab targets tumor necrosis factor-alpha, not T cells. B: Cetuximab targets epidermal growth factor receptor, not T cells. C: Rituximab targets CD20 antigen on B cells, not T cells.
