Question 1 of 5
The nurse is reinforcing teaching to a person who has tested positive for HIV. Which test should the nurse explain is done to confirm the diagnosis of HIV?
Correct Answer: A
Rationale: The correct answer is A: Western blot. This test is used to confirm the diagnosis of HIV by detecting specific antibodies produced in response to the virus. It is considered the gold standard for confirming HIV infection due to its high specificity and sensitivity. The other choices (B, C, D) are not used to diagnose HIV. Rheumatoid factor and antinuclear antibodies are tests for autoimmune conditions, while immunoglobulin assay measures levels of antibodies in the blood, not specific to HIV.
Question 2 of 5
Which group(s) of fungi do not generally produce sexual reproductive structures and are also sometimes known as imperfect fungi?
Correct Answer: E
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
Match the following terms (1-6) with their respective meanings (A-F).
Correct Answer: C
Rationale: The correct match for the terms is: 1 - D 2 - C 3 - B 4 - E 5 - A 6 - F Rationale: 1. Term 1 corresponds to definition D, as per choice C. 2. Term 2 matches with definition C, as per choice C. 3. Term 3 aligns with definition B, as per choice C. 4. Term 4 correlates with definition E, as per choice C. 5. Term 5 matches with definition A, as per choice C. 6. Term 6 corresponds to definition F, as per choice C. Summary: - Choice A has incorrect matches for terms 1, 2, 3, 5, and 6. - Choice B has incorrect matches for terms 1, 2, 3, and 4. - Choice D has incorrect matches for terms 1, 2, 4, and 6. Therefore, the correct answer
Question 4 of 5
Which compounds produced by microorganisms can cause fever in humans and can withstand autoclaving?
Correct Answer: D
Rationale: The correct answer is D, peptidoglycan. Peptidoglycan is a component of bacterial cell walls that can trigger fever in humans. It is a sturdy molecule that can withstand autoclaving. A: Endotoxin is a component of the outer membrane of Gram-negative bacteria, not resistant to autoclaving. B: Lipid A is the toxic component of endotoxin, not resistant to autoclaving. C: Lipopolysaccharide is the major component of the outer membrane of Gram-negative bacteria, not resistant to autoclaving.
Question 5 of 5
Select incorrect mechanism for the development of autoimmune disorder.
Correct Answer: A
Rationale: The correct answer is A. A second exposure to an allergen does not lead to the development of autoimmune disorders. The key mechanisms involved in autoimmune disorders are self-tolerance breakdown and immune system attacking self-antigens. Explanation: 1. B: Cross-reaction of antibodies formed against foreign antigens with self-antigens is a possible mechanism for autoimmune disorders. 2. C: Exposure of previously 'hidden' self-antigens to the adaptive immune system can trigger autoimmune responses. 3. D: Mutation followed by the appearance of membrane proteins not previously present can lead to autoimmune disorders, as the immune system may recognize these proteins as foreign. Summary: Choice A is incorrect because a second exposure to an allergen does not cause the immune system to target self-antigens, which is the hallmark of autoimmune disorders. Choices B, C, and D are more plausible mechanisms for the development of autoimmune disorders.
