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:
Cosmetic surgery is performed to improve the appearance of a body part. It is elective and usually not medically necessary. In the case of fallopian tube removal due to endometriosis, the surgery is not performed for aesthetic reasons but to relieve pain and treat a medical condition.
Choice B reason:
Diagnostic surgery is carried out to diagnose a condition. While endometriosis can be diagnosed through surgery, the removal of the fallopian tube in this scenario is not for diagnostic purposes but rather for treatment.
Choice C reason:
Constructive surgery is done to restore function or normal appearance by reconstructing defective organs or body parts. The removal of the fallopian tube for endometriosis does not fit this category as it does not aim to reconstruct but rather to remove a part causing pain.
Choice D reason:
Ablative surgery involves the removal of an organ or abnormal growth. It is often used to treat conditions that cause pain or to prevent further complications. The removal of the fallopian tube due to severe endometriosis falls under this category as it aims to alleviate symptoms and prevent further issues related to the condition.
Correct Answer is A
Explanation
Choice a) Raloxifene:
Raloxifene is part of a class of drugs known as selective estrogen-receptor modulators (SERMs). It works by imitating the beneficial effects of the hormone estrogen on your bones, helping to prevent bone loss and improve density. Therefore, it is used in the prevention and treatment of osteoporosis.
Choice b) Calcitonin:
Calcitonin is a hormone that a person’s thyroid gland produces. It helps regulate the amount of calcium in the body. For the treatment of postmenopausal osteoporosis, scientists typically extract calcitonin from salmon. This is because salmon calcitonin has a much higher potency than human calcitonin. Osteoclasts are cells in the body that degrade bone. Calcitonin can inhibit osteoclasts. This helps slow the loss of bone density and increases bone mass, hindering the progression of osteoporosis.
Choice c) Allopurinol:
Allopurinol is primarily used to treat gout and certain types of kidney stones. It is not typically used in the prevention or treatment of osteoporosis.
Choice d) Levothyroxine:
Levothyroxine is used to treat hypothyroidism (underactive thyroid). It is not typically used in the prevention or treatment of osteoporosis. However, if you are prescribed levothyroxine you should have regular blood tests, at least once a year, to ensure your thyroid hormone levels are not too high. Continuous high thyroid hormone levels may lead to developing or worsening of low bone density and osteoporosis.
