Immune System Test Quizlet Questions
Question 1 of 5
Monoclonal antibodies can be used to:
Correct Answer: D
Rationale: The correct answer is D because monoclonal antibodies have the ability to block the proliferation of cancer cells by targeting specific antigens on the cancer cells. They can also target cancer cells for destruction through various mechanisms such as antibody-dependent cell-mediated cytotoxicity. Additionally, monoclonal antibodies can inhibit inflammatory immune responses by neutralizing pro-inflammatory mediators or blocking immune cell activation pathways. Therefore, all the options A, B, and C are correct, making D the correct answer.
Question 2 of 5
Which of the following is NOT a property of CD8+ T cells?
Correct Answer: D
Rationale: The correct answer is D because CD8+ T cells are not responsible for antibody-dependent cell-mediated cytotoxicity. A is correct as CD8+ T cells differentiate into cytotoxic T cells. B is correct as CD8+ T cells recognize peptide antigens with MHC molecules. C is correct as CD8+ T cells are vital in defense against intracellular pathogens. D is incorrect as CD8+ T cells do not mediate cell cytotoxicity through antibodies.
Question 3 of 5
Select the correct number of statements that are true.
Correct Answer: A
Rationale: The correct answer is A. Statement 1 and 3 are true because selecting them would result in a correct answer. Statement 2 is incorrect as it claims that only 2 and 4 are correct, which contradicts the correct answer. Statement 4 is also incorrect as it claims that only 3 and 4 are correct, which is not consistent with the correct answer. The option "All of the above are correct" (D) is false because it includes statement 2, which is incorrect. Therefore, A is the correct choice because it accurately identifies the true statements.
Question 4 of 5
Which of the following is not a Covid-19 vaccine?
Correct Answer: A
Rationale: Step-by-step rationale: 1. Nuvaxovid is not a known Covid-19 vaccine. 2. Covovax and Moderna are both established Covid-19 vaccines. 3. "None of the above" includes all listed options, so it is not the correct answer. 4. Therefore, the correct answer is A: Nuvaxovid, as it is not a recognized Covid-19 vaccine.
Question 5 of 5
The nurse is administering medications to a patient. Which medications should the nurse understand is being given to suppress C-reactive protein levels?
Correct Answer: A
Rationale: The correct answer is A: Aspirin and steroids. Aspirin is known to suppress C-reactive protein levels by inhibiting inflammatory pathways. Steroids also have anti-inflammatory properties that can lower CRP levels. Antibiotics, diuretics, epinephrine, antihistamines, antihypertensives, and antineoplastic agents do not have direct effects on CRP levels. It is important for the nurse to understand the mechanism of action of medications to ensure safe and effective administration.
