Question 1 of 5
A client is having blood tests and has an elevated lymphocyte level. Based on knowledge of cellular components, what does the nurse know about these cells?
Correct Answer: C
Rationale: Lymphocytes are a type of white blood cells that play a crucial role in supporting the body's immune system. They are responsible for producing substances that protect the body against infections and foreign substances that could potentially harm the client. Lymphocytes consist of two main types: T cells, which are produced in the thymus, and B cells, which are produced in the lymphatic tissue.
Choice A is incorrect because histamine is mainly associated with basophils and mast cells, not lymphocytes.
Choice B is incorrect as phagocytosis is a function of other white blood cells such as neutrophils and macrophages.
Choice D is also incorrect as carrying hemoglobin and oxygen is a function of red blood cells, not lymphocytes.
