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:
Measuring the circumference of the thigh can be part of the assessment for swelling or edema, which may indicate compartment syndrome or other issues. However, it is not a direct measure of neurovascular status, which focuses on blood flow and nerve function.
Choice B reason:
Palpating the femoral pulse is important for assessing blood flow to the leg, but for a midshaft femur fracture, more distal pulses such as the popliteal, dorsalis pedis, or posterior tibial pulses would be more indicative of the neurovascular status of the affected limb.
Choice C reason:
Monitoring the client's calf for edema is a useful technique for identifying signs of swelling that could suggest complications like deep vein thrombosis or compartment syndrome. However, it does not provide a complete picture of neurovascular integrity, which also includes sensory and motor function assessment.
Choice D reason:
Instructing the client to wiggle his toes is a direct assessment of motor function, which is a key component of neurovascular status. This action, along with checking for sensation and capillary refill, helps to determine if there is any impairment in nerve function or blood supply to the affected area.
Correct Answer is B
Explanation
Choice A reason:
The statement "This procedure is routinely performed during a Pap test" is incorrect. A colposcopy is not routinely performed during a Pap test; it is a separate procedure that is often recommended if a Pap test shows abnormal results. The colposcopy allows for a closer examination of the cervix, vagina, and vulva to detect any signs of disease.
Choice B reason:
The statement "During the procedure, a biopsy may be performed" is correct. If the healthcare provider sees an area of concern during the colposcopy, they may take a small sample of tissue (biopsy) from the cervix or from inside the opening of the cervix.
Choice C reason:
The statement "Do not eat or drink after midnight tonight" is not necessary for a colposcopy. Unlike some surgical procedures that require general anesthesia, a colposcopy is usually done with local anesthesia, and fasting is not required.
Choice D reason:
The statement "You will have general anesthesia during this procedure" is incorrect. General anesthesia is not typically used for a colposcopy. The procedure may cause some discomfort, but it is usually performed using local anesthesia or no anesthesia at all.
