Basic Immune System Quizlet Questions
Question 1 of 5
The nurse is instructing a patient with rheumatoid arthritis about a prescribed exercise program. Which information should the nurse include?
Correct Answer: A
Rationale: The correct answer is A because a consistent exercise routine is important for managing rheumatoid arthritis. Performing exercises every day helps improve joint mobility and strength without causing excessive strain. Option B is incorrect as exercising during inflammation can worsen symptoms. Option C is incorrect as exercising past the point of pain can lead to injury. Option D is incorrect as overcompensating the following day can also lead to injury and disrupt the exercise program's consistency.
Question 2 of 5
The dark zone of germinal centers (GC) is composed of
Correct Answer: A
Rationale: The dark zone of germinal centers is composed of rapidly proliferating B cells. This is because during the dark zone phase of the germinal center reaction, B cells undergo rapid proliferation and somatic hypermutation to generate high-affinity antibodies. T cells and dendritic cells are typically found in the light zone of the germinal centers where B cells interact with them to receive signals for selection. Rapidly proliferating T cells are not typically found in the dark zone. Follicular dendritic cells are present in the light zone where they present antigens to B cells but not in the dark zone where B cell proliferation mainly occurs.
Question 3 of 5
The current Influenza vaccine includes
Correct Answer: B
Rationale: Step 1: The current Influenza vaccine is designed to provide protection against multiple strains to increase effectiveness. Step 2: Option B includes a combination of different strains (H1N1, H5N1, and B), covering a broader spectrum of the virus. Step 3: Including different strains helps to address potential mutations and variations in circulating viruses. Step 4: Option B is the most comprehensive choice compared to others, offering a more robust protection against various strains. Summary: Option A is too limited with only 3 type A strains, while option C focuses only on 2009 H1N1 strain. Option D is also limited to only the most common seasonal H1N1 strain. Option B stands out as the correct choice for its broad coverage of different strains.
Question 4 of 5
"Hamburger disease" is caused by
Correct Answer: C
Rationale: The correct answer is C: A strain of E. coli. "Hamburger disease" is commonly caused by E. coli O157:H7, a strain of Escherichia coli bacteria found in undercooked ground beef. This strain can lead to severe foodborne illness. Helicobacter pylori (Choice A) is associated with stomach ulcers, not hamburger disease. Salmonella typhimurium (Choice B) and Shigella flexneri (Choice D) are both known to cause food poisoning, but they are not typically linked to hamburger disease specifically. In this case, the unique association between E. coli O157:H7 and undercooked ground beef makes Choice C the correct answer.
Question 5 of 5
What is Louis Pasteur's main contribution to immunology?
Correct Answer: C
Rationale: Louis Pasteur's main contribution to immunology is the germ theory of disease and vaccine development. Firstly, Pasteur's germ theory revolutionized our understanding of infectious diseases by demonstrating that microorganisms are the cause. Secondly, he developed the concept of vaccination by creating vaccines for diseases such as rabies and anthrax, laying the foundation for modern immunology. The other choices are incorrect because: A: Pasteur worked on the rabies vaccine, not the smallpox vaccine. B: Phagocytosis was discovered by Metchnikoff, not Pasteur. D: Pasteur did not propose the theory of innate immunity.
