Immune System Exam Questions Questions
Question 1 of 5
Neutrophils, bands, basophils, eosinophils, platelets increased. Suggests?
Correct Answer: C
Rationale: The increased presence of neutrophils, bands, basophils, eosinophils, and platelets suggests Chronic Myelocytic Leukemia (CML). In CML, there is a high proliferation of myeloid cells leading to an increase in these cell types. Neutrophils, basophils, and eosinophils are myeloid cells, and their elevated levels are characteristic of CML. Bands are immature neutrophils also seen in CML. Platelets can be increased due to the bone marrow's overproduction of cells. Acute myeloid leukemia (Choice A) typically presents with blasts, not mature cells like in this scenario. Acute lymphoid leukemia (Choice B) involves the overproduction of lymphoid cells, not myeloid cells as seen here. LAP score is typically low in CML, not high as in Choice D.
Question 2 of 5
Examples of autoimmune diseases except:
Correct Answer: A
Rationale: The correct answer is A: Malaria. Autoimmune diseases are conditions where the immune system mistakenly attacks the body's own cells. Malaria, on the other hand, is caused by a parasite transmitted through mosquito bites and does not involve the immune system attacking the body. Pernicious anemia, Grave's disease, and Hashimoto's disease are all autoimmune diseases where the immune system targets specific tissues or organs in the body. Therefore, A is the correct answer as it does not fit the definition of an autoimmune disease, unlike the other choices.
Question 3 of 5
Client anxious about bone marrow biopsy. Best action?
Correct Answer: A
Rationale: The correct answer is A: Assess fears and coping mechanisms. This is the best action because it allows the healthcare provider to understand the specific anxieties the client has about the bone marrow biopsy. By assessing fears and coping mechanisms, the healthcare provider can tailor their approach to provide appropriate support and information. Reassuring it's a common test (B) may not address the client's specific fears. Sedating prior to the procedure (C) may not be necessary if the client's anxiety can be adequately managed through other means. Telling the client they'll be asleep (D) may not address the underlying anxieties and may lead to false expectations.
Question 4 of 5
A nurse is planning the care of a client who requires immunosuppression to ensure engraftment of depleted bone marrow during a transplantation procedure. What is the most important component of infection control in the care of this client?
Correct Answer: D
Rationale: The correct answer is D: Thorough and consistent hand hygiene. This is essential to prevent the transmission of microorganisms between the client and healthcare providers. Hand hygiene is the most effective measure to reduce the risk of infection in healthcare settings. IVIG (A) is not directly related to infection control. Antibiotic administration (B) is important in treating infections but does not prevent transmission. While appropriate use of gloves and goggles (C) is important, it is not as critical as hand hygiene in preventing infections.
Question 5 of 5
A client with a recent diagnosis of HIV infection expresses an interest in exploring alternative and complementary therapies. How should the nurse best respond?
Correct Answer: C
Rationale: Step 1: Acknowledge client interest in alternative therapies. Step 2: Provide balanced information about alternative therapies. Step 3: Emphasize benefits and risks of alternative therapies. Step 4: Encourage open discussion and decision-making with healthcare provider. Choice C is correct as it acknowledges client autonomy, provides information, and promotes informed decision-making. Choice A is incorrect as it dismisses alternative therapies outright. Choice B is incorrect as it discourages without considering individual preferences. Choice D is incorrect as it presents a binary choice without discussing the nuances of treatment options.
