Question 1 of 5
Which of the following blood types would the nurse identify as the rarest?
Correct Answer: B
Rationale: The correct answer is B (AB). AB blood type is the rarest because it is a result of inheriting both A and B alleles, making it less common in the population. AB individuals can only receive blood from other AB individuals due to their unique antigens. Blood types A, B, and O are more common in the population, with O being the most common as it is the universal donor. Blood type A and B are more common than AB since they only require one allele for their respective antigens. Thus, the rarity of AB blood type is due to the inheritance of both A and B alleles, making it the least common among the choices provided.
Question 2 of 5
A client is diagnosed with human immunodeficiency virus (HIV). After recovering from the initial shock of the diagnosis, the client expresses a desire to learn as much as possible about HIV and acquired immunodeficiency syndrome (AIDS). When teaching the client about the immune system, the nurse states that adaptive immunity is provide by which type of white blood cell?
Correct Answer: D
Rationale: The correct answer is D: Lymphocyte. Lymphocytes are a type of white blood cell that play a crucial role in adaptive immunity. They include T cells and B cells, which are responsible for recognizing and attacking specific pathogens. T cells help regulate the immune response and directly attack infected cells, while B cells produce antibodies to target pathogens. Neutrophils (A), monocytes (B), and basophils (C) are important for innate immunity, not adaptive immunity. Neutrophils are phagocytic cells that engulf and destroy pathogens, monocytes differentiate into macrophages to engulf pathogens, and basophils are involved in allergic reactions. Therefore, the correct answer is D because lymphocytes are key players in adaptive immunity.
Question 3 of 5
In teaching a female client who is HIV positive about pregnancy, the nurse would know more teaching is necessary when the client says:
Correct Answer: B
Rationale: The correct answer is B because starting birth control pills does not protect against HIV transmission to the baby during pregnancy. The other choices demonstrate understanding of HIV transmission risks and prevention methods. A shows awareness of vertical transmission, C recognizes that not all babies born to HIV-positive mothers are infected, and D acknowledges the potential need for a C-section to reduce transmission risk. Starting birth control pills is unrelated to preventing mother-to-child HIV transmission during pregnancy.
Question 4 of 5
What is the causative agent in HIV/AIDS?
Correct Answer: C
Rationale: The correct answer is C: Human, T-cell lymphotrophic virus, as it is the causative agent for HIV/AIDS. This virus specifically targets and infects the body's T-cells, weakening the immune system. Trichomonas vaginalis, Treponema pallidum, and Chlamydia trachomatis are all different pathogens that do not cause HIV/AIDS. Trichomonas vaginalis is a protozoan parasite that causes trichomoniasis, Treponema pallidum causes syphilis, and Chlamydia trachomatis causes chlamydia. Therefore, the correct answer is C based on the specific viral agent responsible for HIV/AIDS.
Question 5 of 5
The nurse is preparing to assist the physician with a bone marrow biopsy. Which of the ff. interventions is most important for the nurse to do before the procedure?
Correct Answer: B
Rationale: The correct answer is B: Observe the patient for bleeding. Before a bone marrow biopsy, it is crucial to monitor the patient for bleeding tendencies as the procedure can cause bleeding. This step ensures early detection and prompt intervention if bleeding occurs. Explanation for other choices: A: Explaining the procedure to the family is important for informed consent but not the most crucial before the procedure. C: Administering an analgesic may be necessary for pain management but monitoring for bleeding takes precedence. D: Draping the biopsy site is important for maintaining a sterile field but does not directly impact patient safety like monitoring for bleeding.
