Correct Answer: B

Rationale: Clients with internal radiation implants (also known as brachytherapy) emit a small amount of radiation, which can pose a risk to others. Pregnant women are particularly vulnerable to the harmful effects of radiation because it can affect both the mother and the developing fetus. Radiation exposure can lead to birth defects, miscarriage, or other developmental issues, so pregnant women should avoid any exposure by not entering the client's room.

Correct Answer: A

Rationale: Fatigue and weakness are common side effects of radiation therapy, often due to the body's response to radiation damage and the energy required to repair both cancerous and healthy cells affected by the treatment. Reassuring the patient that these symptoms are expected while also emphasizing ongoing monitoring (through lab and x-ray studies) provides both comfort and a sense of proactive care. It ensures the patient that their symptoms are being addressed in a safe and medically appropriate way.

Correct Answer: B

Rationale: Malignant (cancer) cells often express tumor-specific antigens (TSAs), which are proteins or markers on the surface of cancer cells that are not found on normal cells. These antigens are produced due to genetic mutations in cancer cells and can sometimes be used to help the immune system recognize and attack cancerous cells. Tumor-specific antigens play a key role in cancer diagnosis, monitoring, and targeted therapies.

Correct Answer: B

Rationale: In oncology patients, particularly those undergoing chemotherapy or radiation therapy, myelosuppression (the decrease in bone marrow activity that leads to reduced white blood cells, red blood cells, and platelets) increases the risk of infection. Maintaining skin integrity is crucial because the skin acts as the body's first line of defense against infections. If the skin becomes compromised, such as through radiation burns, rashes, or breakdowns, it provides a potential entry point for pathogens, increasing the risk of infection. Since infections in oncology patients can quickly become severe due to their weakened immune systems, maintaining skin integrity is a critical intervention to reduce infection risk, especially for patients who are immunosuppressed.

Correct Answer: B

Rationale: Difficulty swallowing (dysphagia) following radiation therapy to the neck area is a significant concern because it can indicate serious complications such as esophageal stricture, inflammation, or damage to the surrounding tissues, including the esophagus. This can lead to malnutrition, dehydration, or aspiration, all of which require prompt intervention. Radiation therapy can cause irritation and scarring in the esophageal and throat tissues, which may progressively worsen if not treated. Therefore, dysphagia should be addressed immediately to prevent further complications.
