Questions on the Immune System Questions
Question 1 of 5
Döhle bodies mostly seen in?
Correct Answer: B
Rationale: The correct answer is B: Leukemoid reaction. Döhle bodies are blue-gray cytoplasmic inclusions seen in neutrophils, indicating rough endoplasmic reticulum disruption. Leukemoid reaction is a benign condition with elevated white blood cell count due to infections, inflammation, or stress. In chronic myeloid leukemia (A), abnormal myeloid cells are present but not Döhle bodies. Chediak-Higashi syndrome (C) is a rare genetic disorder with giant granules in neutrophils, not Döhle bodies. Infectious mononucleosis (D) shows atypical lymphocytes but not Döhle bodies.
Question 2 of 5
Type 1 hypersensitivity involves:
Correct Answer: A
Rationale: Step 1: Type 1 hypersensitivity is an immediate allergic reaction. Step 2: IgE antibodies are responsible for triggering Type 1 hypersensitivity reactions. Step 3: IgG is not involved in Type 1 hypersensitivity. Step 4: Delayed reactions (Choice C) are not characteristic of Type 1 hypersensitivity. Therefore, the correct answer is A: IgE, as it is the key mediator of Type 1 hypersensitivity reactions. Choices B and C are incorrect because IgG is not involved and Type 1 hypersensitivity is not a delayed reaction. Choice D is incorrect because it includes choices B and C, which are not relevant to Type 1 hypersensitivity.
Question 3 of 5
After reviewing lab results, which client to see first?
Correct Answer: C
Rationale: The correct answer is C: Prothrombin time 28 seconds. A prolonged prothrombin time indicates impaired blood clotting function, posing a higher risk of bleeding. This is a critical issue that requires immediate attention to prevent severe complications. INR of 2.8 (choice A) is slightly elevated but not as urgent as PT. Platelet count of 128,000/mm³ (choice B) is low but not an immediate concern unless it drops further. RBC count of 5.1 million/L (choice D) is within the normal range and does not indicate an urgent issue.
Question 4 of 5
A nurse caring for a client who has an immunosuppressive disorder knows that continual monitoring of the client is critical. What is the primary rationale behind the need for continual monitoring?
Correct Answer: C
Rationale: The correct answer is C. Continual monitoring is crucial for early detection and treatment of infections in clients with immunosuppressive disorders. By closely observing the client's condition, the nurse can identify subtle signs of infection early, allowing prompt intervention to prevent complications. Choices A, B, and D do not directly address the primary rationale for monitoring immunosuppressed clients. Meeting functional needs, administering medications, and maintaining accurate documentation are important but not as critical as detecting and treating infections promptly in this population.
Question 5 of 5
A nurse is performing an admission assessment on a client with stage 3 human immunodeficiency virus (HIV). After assessing the client's gastrointestinal system and analyzing the data, which nursing diagnosis is most likely to be the priority?
Correct Answer: B
Rationale: The correct answer is B: Diarrhea. For a client with stage 3 HIV, diarrhea is a priority nursing diagnosis due to the increased risk of opportunistic infections and medication side effects causing gastrointestinal disturbances. Diarrhea can lead to dehydration, electrolyte imbalances, and malnutrition, which can exacerbate the client's condition. Acute abdominal pain (choice A) may be a symptom of an underlying issue, but addressing diarrhea is more crucial in this case. Bowel incontinence (choice C) and constipation (choice D) are not typically associated with stage 3 HIV and are less urgent compared to diarrhea in this scenario.
