The practical nurse (PN) knows that AIDS is a viral infection that compromises the effectiveness of the immune system. Which component of the immune system is characteristically affected?
Lymph nodes.
Spleen.
T cells.
B cells.
The Correct Answer is C
Choice A reason: Lymph nodes are important components of the immune system and play a crucial role in filtering harmful substances and housing lymphocytes. While HIV/AIDS can affect lymph nodes, it is not the primary target of the virus.
Choice B reason: The spleen is another vital organ in the immune system that helps filter blood and fight infections. However, it is not the specific target of HIV.
Choice C reason: T cells, specifically CD4+ T cells, are the main target of HIV (the virus that causes AIDS). HIV infects and destroys these cells, leading to a weakened immune system. The progressive loss of CD4+ T cells impairs the body's ability to fight off infections and certain cancers, which is characteristic of AIDS.
Choice D reason: B cells are responsible for producing antibodies and play a key role in the humoral immune response. While HIV/AIDS can indirectly impact B cell function due to the overall compromised immune system, B cells are not the primary cells affected by the virus.

Correct Answer is C
Explanation
Choice A reason: Placing the food and utensils in the client's left visual field and leaving him alone does not address the underlying issue of the visual field deficit. While it may temporarily solve the problem of the client eating only the food on the left side, it does not encourage the client to adapt to or compensate for the right homonymous hemianopsia. The goal of rehabilitation is to help the client develop strategies to manage their condition independently, and this approach does not foster such skills.
Choice B reason: Feeding the client foods that are on the right side of his visual field is not the most effective approach, as it does not promote the client's independence or help them adapt to their visual field deficit. While it ensures the client consumes the food on the right side, it does not teach the client to compensate for their hemianopsia, which is an essential aspect of their rehabilitation.
Choice C reason: Reminding the client to look all over the tray to view and eat all the foods provided is the best approach. This action helps the client become more aware of their visual field deficit and encourages them to develop the habit of scanning their environment. Teaching the client to consistently look around their entire visual field promotes independence and helps them adapt to daily activities despite their condition. This strategy supports the goal of rehabilitation, which is to enhance the client's ability to manage their visual impairment independently.
Choice D reason: Prompting the client to rotate his plate to see foods on the right side of the tray is a practical solution, but it does not address the broader need for the client to learn to scan their environment. While rotating the plate may temporarily help the client access the food on the right side, it does not encourage the development of compensatory strategies for the visual field deficit. Encouraging the client to look all over the tray is a more effective approach for long-term adaptation and independence.
Correct Answer is D
Explanation
Choice A reason: Flushed, hot skin is not directly related to the client's CBC results. This symptom can indicate various conditions, such as fever, inflammation, or an allergic reaction, but it does not specifically correlate with the lab findings provided. The client's WBC count, hemoglobin, hematocrit, and basophils are within normal ranges, and the most significant abnormality is the low platelet count.
Choice B reason: Hives, or urticaria, are typically associated with allergic reactions and not directly related to the client's CBC results. While a low platelet count can sometimes be associated with immune-mediated conditions, hives are not a primary symptom of thrombocytopenia (low platelet count). The main concern with a low platelet count is the increased risk of bleeding and bruising.
Choice C reason: Inelastic turgor is a sign of dehydration or poor skin elasticity, often seen in conditions such as severe dehydration or malnutrition. The client's CBC results do not indicate dehydration or issues with skin turgor. The hemoglobin and hematocrit levels are within normal ranges, suggesting that the client's overall fluid status is likely stable.
Choice D reason: Bruising is the most relevant finding to assess for in a client with a low platelet count (thrombocytopenia). Platelets play a crucial role in blood clotting, and a low platelet count increases the risk of bleeding and easy bruising. The client's platelet count of 98,000/mm³ (98 x 10⁹/L) is below the normal range, which predisposes them to bruising and potential bleeding complications. It is important for the practical nurse to assess for signs of bruising and bleeding and to monitor the client closely for any further complications.
