Question 1 of 5
A baby is born temporarily immune to the diseases to which the mother is immune. The nurse understands that this is an example of which of the following types of immunity?
Correct Answer: A
Rationale: The correct answer is A: Naturally acquired passive immunity. This type of immunity occurs when antibodies are passed from mother to baby through the placenta or breast milk, providing temporary protection. The baby does not produce its antibodies, hence it is passive. Choice B, naturally acquired active immunity, involves the body producing its antibodies after exposure to a pathogen. Choice C, artificially acquired passive immunity, involves receiving preformed antibodies from an external source. Choice D, artificially acquired active immunity, involves the body producing antibodies in response to vaccination.
Question 2 of 5
Which of the following would the nurse evaluate as laboratory data that support the occurrence of AIDS?
Correct Answer: D
Rationale: The correct answer is D: 200 CD4+ cells. In AIDS, the immune system is severely compromised, leading to a decrease in CD4+ T cells. A CD4+ count below 200 cells/mm3 is a key indicator of AIDS, as it signifies advanced immunodeficiency. Choices A, B, and C all have CD4+ cell counts above 200, which would not support the occurrence of AIDS. Therefore, the nurse would evaluate a CD4+ count of 200 cells as laboratory data that support the occurrence of AIDS.
Question 3 of 5
The nurse is caring for a client with thrombocytopenia. What is the best way to protect this client?
Correct Answer: C
Rationale: The correct answer is C: Use the smallest needle possible for injections. This is important for a client with thrombocytopenia because they have a low platelet count, leading to an increased risk of bleeding. Using a small needle minimizes the risk of causing bleeding or bruising during injections. Limiting family visits (choice A) is not directly related to protecting the client from bleeding. Encouraging wheelchair use (choice B) is not specifically relevant to protecting the client with thrombocytopenia. Maintaining accurate fluid intake and output records (choice D) is important but not directly related to preventing bleeding in a client with thrombocytopenia.
Question 4 of 5
In a client who has human immunodeficiency virus (HIV) infection, CD4+ levels are measured to determine the:
Correct Answer: B
Rationale: Step-by-step rationale: 1. CD4+ cells are a type of white blood cell crucial for immune function. 2. HIV targets and destroys CD4+ cells, leading to immune system damage. 3. Measuring CD4+ levels helps determine the extent of this damage. 4. Therefore, the correct answer is B. Summary: A: Presence of opportunistic infections - CD4+ levels indirectly affect susceptibility, but not measured for this purpose. C: Level of the viral load - Measured separately from CD4+ levels. D: Resistance to antigens - CD4+ levels do not directly indicate resistance.
Question 5 of 5
For a client diagnosed with idiopathic thrombocytopenic purpura (ITP), which nursing intervention is appropriate?
Correct Answer: B
Rationale: The correct answer is B: Administering platelets, as ordered to maintain an adequate platelet count. In ITP, the client has low platelet count leading to risk of bleeding. Administering platelets helps raise platelet levels and prevent bleeding complications. Teaching coughing and deep-breathing techniques (A) is important for preventing respiratory infections but not directly related to ITP. Giving aspirin (C) is contraindicated as it can further decrease platelet count. Administering stool softeners (D) is important for preventing straining but not specific to managing ITP.
