Immune System Quiz Quizlet Questions
Question 1 of 5
Which of the following is an example of passive immunization?
Correct Answer: C
Rationale: Passive immunization involves the transfer of pre-formed antibodies to confer immediate protection. Choice C is correct as it describes receiving serum containing antibodies from an immune individual. Choice A is incorrect because it describes active immunization. Choice B is incorrect as it refers to the primary immune response, which is part of active immunization. Choice D is incorrect as it describes the process of immunization itself, not passive immunization.
Question 2 of 5
Which of the following is an example of a live attenuated bacterial vaccine?
Correct Answer: B
Rationale: The correct answer is B: Typhoid. Live attenuated vaccines contain weakened forms of the pathogen that can replicate in the host to stimulate a strong immune response without causing disease. Typhoid vaccine is an example of a live attenuated bacterial vaccine because it contains weakened Salmonella typhi bacteria. Cholera (A), Anthrax (C), and Plague (D) vaccines are not live attenuated bacterial vaccines; they are either killed/inactivated or subunit vaccines. Live attenuated vaccines provide longer-lasting immunity compared to other vaccine types.
Question 3 of 5
The nurse notes that a patient's eosinophil level is elevated. For which health problem should the nurse plan care for this patient?
Correct Answer: B
Rationale: The elevated eosinophil level indicates an allergic reaction. Eosinophils are white blood cells involved in allergic responses. They increase in response to allergens. Allergic reactions involve the immune system's response to harmless substances, triggering the release of eosinophils. Cancer, acute viral infections, and autoimmune diseases typically do not directly cause eosinophil elevation. Therefore, the correct answer is B (Allergic reactions).
Question 4 of 5
During data collection, the nurse learns the patient is allergic to shellfish. Which precautions should be implemented during the patient's hospitalization?
Correct Answer: D
Rationale: Rationale: 1. The correct answer is D because it addresses the essential action of noting the patient's allergy on the medical record and communicating it to all caretakers to prevent inadvertent exposure. 2. Choice A is not necessary unless the patient's allergy poses an infection control risk that warrants isolation. 3. Choice B is excessive and not required as long as cross-contamination is prevented during food preparation. 4. Choice C is unrelated to the patient's shellfish allergy and not a standard precaution in this scenario.
Question 5 of 5
Who accidentally identified the antimicrobial action of penicillin?
Correct Answer: C
Rationale: The correct answer is C: Alexander Fleming. Fleming discovered the antimicrobial action of penicillin in 1928 through his experiment with Staphylococcus bacteria. He noticed that mold from a contaminated petri dish inhibited the growth of the bacteria. Robert Koch (A) is known for his work in identifying specific bacteria causing diseases. Richard Petri (B) is not a known figure in the field of microbiology. Louis Pasteur (D) is famous for his germ theory and pasteurization, but he did not discover penicillin's antimicrobial action. Therefore, based on historical evidence and Fleming's specific contribution to microbiology, choice C is the correct answer.
