A nurse is assessing a client's immune function by reviewing the laboratory value of the cellular response of the T-cells. The nurse should recognize that which of the following conditions is affected by the T-cells?
Hay fever allergy
Anaphylaxis
Transplant rejection
Bacterial phagocytosis
The Correct Answer is C
Choice A reason:
Hay fever allergy, also known as allergic rhinitis, is primarily associated with the action of Immunoglobulin E (IgE) antibodies and not directly with T-cells. T-cells can contribute to the regulation of the immune response in allergies, but IgE is the main immunoglobulin involved in the typical symptoms of hay fever.
Choice B reason:
Anaphylaxis is a severe, potentially life-threatening allergic reaction that involves the release of large amounts of histamine and other chemicals from mast cells and basophils, often triggered by IgE antibodies. While T-cells can play a role in the sensitization phase of allergy, anaphylaxis itself is not directly caused by T-cells.
Choice C reason:
Transplant rejection is a process in which T-cells play a central role. When a transplant recipient's immune system recognizes the donated organ as foreign, T-cells can mediate the rejection by attacking the transplanted tissue, leading to its failure.
Choice D reason:
Bacterial phagocytosis is primarily the function of phagocytes like neutrophils and macrophages. T-cells are involved in the adaptive immune response and can activate phagocytes, but they do not directly perform phagocytosis.

Correct Answer is D
Explanation
Choice A reason:
Hyperplasia is an increase in the number of cells in an organ or tissue, which can lead to its enlargement. While hyperplasia can be a response to a stimulus and is not necessarily precancerous, it does not describe the abnormal changes in the shape, size, and organization of mature cells.
Choice B reason:
Metaplasia is a reversible change in which one differentiated cell type is replaced by another cell type. This process can be a response to chronic irritation and inflammation, and while it may predispose cells to cancerous changes, it is not in itself a precancerous condition.
Choice C reason:
The term 'malignant' refers to cancerous cells that have the ability to invade and destroy nearby tissue and spread to other parts of the body. The description of the cells as 'moderately abnormal' does not indicate that the cells are malignant but rather that they are showing signs of potentially precancerous changes.
Choice D reason:
Dysplasia refers to the presence of abnormal cells within a tissue or organ. It is characterized by changes in cell size, shape, uniformity, arrangement, and structure, particularly when such changes are strongly suggestive of developing neoplasia, or new, abnormal growth. In the context of a Pap smear, dysplasia is indicative of precancerous changes and is the term used to describe the abnormal development of cells on the cervix.
Correct Answer is C
Explanation
Choice A reason:
Hypertension is not typically an early manifestation of fat embolism syndrome (FES). FES is more commonly associated with hypoxemia, which can lead to hypotension rather than hypertension².
Choice B reason:
While a swollen calf may indicate deep vein thrombosis, it is not an early sign of FES. FES primarily affects the lungs and neurological systems early on, rather than causing localized swelling such as in a calf².
Choice C reason:
Tachypnea, or rapid breathing, is indeed an early sign of FES. This symptom usually develops before others and is due to the fat globules causing respiratory distress by blocking the pulmonary microcirculation²³⁴.
Choice D reason:
Bradycardia, or a slower than normal heart rate, is not an early sign of FES. Instead, patients may experience tachycardia as a response to hypoxemia and respiratory distress².
