Immune System Test Quizlet Questions
Question 1 of 5
A nurse has educated a client on an epinephrine autoinjector. What statement by the client indicates additional instruction is needed?
Correct Answer: A
Rationale: The correct answer is A. If the client states they don't need to go to the hospital after using the epinephrine autoinjector, additional instruction is needed. The rationale is that after using an epinephrine autoinjector, it is crucial to seek medical attention immediately due to the potential for severe allergic reactions. Choice B is incorrect because carrying two autoinjectors is recommended in case the first dose is not effective. Choice C is incorrect as it demonstrates good practice in tracking the expiration date. Choice D is incorrect as it is acceptable to inject through clothes in an emergency situation.
Question 2 of 5
A TH2 immune response will not induce
Correct Answer: E
Rationale: The correct answer is E because a TH2 immune response is associated with isotype switching to IgE and secretion of IL-4, which are essential for allergic responses. Activation of macrophages is not associated with a TH2 response. Resistance to Leishmania infection is mediated by a TH1 response, not TH2.
Question 3 of 5
An HIV encoded protein that if targeted therapeutically could result in the blocking of binding of HIV to T lymphocytes is
Correct Answer: E
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Alumn is an adjuvant that triggers
Correct Answer: B
Rationale: The correct answer is B: DAMPs formation. Alum is known to trigger the release of damage-associated molecular patterns (DAMPs), which are endogenous molecules released by damaged cells. This activation of DAMPs plays a crucial role in initiating and enhancing the immune response. The other choices, TLR4, NOD1, and TLR9, are receptors involved in recognizing specific pathogen-associated molecular patterns (PAMPs) rather than DAMPs. Therefore, they are not directly triggered by alum. This makes choice B the correct answer based on the known mechanism of action of alum as an adjuvant.
Question 5 of 5
Indicate the incorrect statement. Chronic granulomatous disease is
Correct Answer: A
Rationale: The correct answer is A. Chronic granulomatous disease (CGD) is caused by mutations of the NADPH oxidase genes, leading to defective respiratory burst in neutrophils. Neutrophils are recruited to sites of infection normally in CGD. Therefore, choice A is incorrect. Choices B, C, and D are incorrect because CGD is indeed associated with defective respiratory burst of neutrophils due to mutations in NADPH oxidase genes, leading to recurrent bacterial infections.
