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 C
Explanation
Choice A reason:
Keeping artificial nails trimmed is a recommended practice in healthcare settings to maintain effective hand hygiene. Long nails can harbor bacteria and make it difficult to clean hands thoroughly. However, the CDC does not provide specific guidelines on the length of artificial nails for healthcare workers.
Choice B reason:
When caring for a client with Clostridium difficile, it is recommended to wash hands with soap and water rather than using alcohol-based hand rubs. Alcohol-based hand rubs are not effective against C. difficile spores. Therefore, thorough handwashing with soap and water is necessary to remove spores.
Choice C reason:
Chlorhexidine is an antiseptic agent that provides broad-spectrum antimicrobial activity and is recommended for hand hygiene in certain situations, such as before invasive procedures or for clients who are immunosuppressed. It is effective against a wide range of bacteria, viruses, and fungi, making it a suitable choice for immunocompromised patients to reduce the risk of infection.
Choice D reason:
The use of alcohol-based hand rubs before administering eye drops is not specifically recommended. While hand hygiene is essential before any contact with a patient, there is no particular preference for alcohol-based hand rubs in this context. The primary concern is to ensure that hands are clean to prevent contamination of the eye drops or the patient's eyes.
Correct Answer is B
Explanation
Choice A reason:
Generalized urticaria, or hives, is not a common side effect of radiation therapy for lung cancer. While skin reactions can occur, they are usually localized to the area being treated. Urticaria might be a sign of an allergic reaction, which would require immediate attention, but it is not typically associated with radiation therapy¹.
Choice B reason:
Xerostomia, or dry mouth, is a common side effect of radiation therapy, especially when the radiation field includes salivary glands. For lung cancer patients, if the radiation field is near the neck or upper chest, it could potentially affect salivary gland function. Monitoring for xerostomia is important because it can lead to difficulties in speaking, eating, and swallowing, and it increases the risk for dental problems².
Choice C reason:
While reviewing laboratory test results for low hemoglobin is an important part of nursing care, it is not specific to radiation therapy for lung cancer. Low hemoglobin could be related to the cancer itself or a side effect of other treatments like chemotherapy. It is important to monitor, but not the primary action related to radiation therapy³.
Choice D reason:
Observing for signs of infection is a general nursing responsibility for all patients, not specific to those receiving radiation therapy for lung cancer. However, if the patient's immune system is compromised due to the cancer or other treatments, vigilance for infection is heightened.
