The nurse is planning preoperative care for a client who has a fractured wrist. Which of the following should the nurse include in the client's plan of care?

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.

Choice A Reason:
A 10 mm wheal is not indicative of TB infection. A wheal is a raised, often itchy area of skin that usually signifies an allergic reaction, not an infection. The TST looks for induration, which is a firm swelling, as a sign of TB infection.

Choice B Reason:
A 5 mm induration is considered positive in certain high-risk groups, such as people living with HIV, recent contacts of TB patients, or those with a history of organ transplants. For individuals without these risk factors, a 5 mm induration is not considered a positive result.

Choice C Reason:
A 15 mm induration is considered a positive TST result for individuals with no known risk factors for TB. This indicates that the person's immune system has reacted to the tuberculin purified protein derivative (PPD) injected under the skin, suggesting exposure to TB bacteria.

Choice D Reason:
Erythema, or redness of the skin, is not measured when interpreting TST results. The test measures induration, which is a palpable, raised, hardened area or swelling. Therefore, a 4 mm erythema does not indicate TB infection.
