Hematologic System Questions Questions
Question 1 of 5
First immunoglobulin in primary response, passed from mother to fetus?
Correct Answer: B
Rationale: Step-by-step rationale: 1. IgM is the first immunoglobulin produced in primary immune response. 2. It is released by plasma cells when an antigen is encountered. 3. IgM is efficient in agglutination and complement activation. Summary of incorrect choices: A: IgA is mainly found in mucosal areas. C: IgE is involved in allergic reactions. D: IgG is the most abundant immunoglobulin in the bloodstream.
Question 2 of 5
At which stage of life are people most commonly diagnosed with PIDD?
Correct Answer: B
Rationale: The correct answer is B: Infancy. Primary Immunodeficiency Disorders (PIDD) are typically diagnosed in infancy due to recurrent infections and failure to thrive. Infants with PIDD often exhibit severe and persistent infections, making diagnosis more apparent at this stage. In contrast, early childhood (A) and adolescence (C) are less common stages for PIDD diagnosis due to the immune system maturing and symptoms becoming more noticeable in infancy. Early adulthood (D) is also less common as PIDD is usually identified earlier in life.
Question 3 of 5
The nurse is addressing condom use in the context of a health promotion workshop. When discussing the correct use of condoms, which instruction should the nurse give the attendees?
Correct Answer: D
Rationale: The correct answer is D: Hold the condom during withdrawal so it doesn't come off. This is crucial to prevent slippage and potential exposure to sexually transmitted infections or unintended pregnancy. Holding the condom during withdrawal maintains its position and reduces the risk of breakage. A: Applying the condom prior to erection is incorrect as it may lead to slippage. B: Reusing a condom is unsafe and increases the risk of breakage and transmission of infections. C: Using skin lotion as a lubricant is not recommended as it can damage the condom and increase the risk of breakage.
Question 4 of 5
A client's primary infection with HIV has subsided and an equilibrium now exists between HIV levels and the client's immune response. This is known as what physiologic state?
Correct Answer: C
Rationale: The correct answer is C: Viral set point. During this stage, the client's immune response has reached a balance with HIV levels, leading to a stable viral load. This term reflects the equilibrium between viral replication and immune control. A: The static stage implies an inactive phase, which does not accurately describe the dynamic balance in the viral set point. B: Latent stage refers to a period of inactivity in viral replication, not the balanced state described in the question. D: The window period is the time between infection and detectable levels of HIV antibodies, not the equilibrium between viral levels and immune response.
Question 5 of 5
You are preparing the client for a bone marrow aspiration and biopsy. Which of the following statements, if made by the patient, indicates the need for further teaching?
Correct Answer: A
Rationale: Correct Answer: A Rationale: 1. Ambulation is encouraged after a bone marrow aspiration to prevent blood clots. 2. Prolonged immobility can increase the risk of complications like deep vein thrombosis. 3. Therefore, the statement indicating to avoid ambulating for 24-48 hours is incorrect and requires further teaching. 4. Other choices (B, C, D) are appropriate and do not raise any concerns regarding patient understanding.
