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

Answer and Explanation

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 A

Explanation

Choice A reason:

The inability to abduct the arm at the shoulder is a classic sign of a rotator cuff injury. The rotator cuff is responsible for stabilizing the shoulder joint and aiding in various movements, including abduction. When there is a tear or significant weakness in the rotator cuff muscles, especially the supraspinatus muscle, the patient may be unable to lift the arm away from the body or may experience pain while doing so.

Choice B reason:

A negative drop arm test would actually indicate that there is no rotator cuff injury. The drop arm test is performed by asking the patient to fully abduct the arm to 90 degrees and then slowly lower it. If the patient can control the motion and lower the arm smoothly, the test is negative. A positive drop arm test, where the patient cannot control the descent of the arm, would suggest a rotator cuff tear.

Choice C reason:

While an alteration in the contour of the joint may indicate some form of shoulder pathology, it is not specific to a rotator cuff injury. Changes in the contour could be due to various conditions, including dislocation, arthritis, or other musculoskeletal disorders.

Choice D reason:

A positive Tinel's sign is used to diagnose nerve compression or nerve damage, not rotator cuff injuries. It is performed by tapping over the course of a nerve to elicit a tingling sensation or pain in the distribution of the nerve. This sign is commonly associated with conditions like carpal tunnel syndrome.

A. Measure the circumference of the thigh. B. Palpate the femoral pulse. C. Monitor the client's calf for edema. D. Instruct the client to wiggle his toes.

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.
