Correct Answer: B

Rationale: Radiation therapy can cause skin irritation, dryness, and sensitivity in the treated area. Wearing loose, soft clothing helps minimize friction and pressure on the skin, reducing irritation and promoting comfort. The skin in the treated area is often more sensitive and vulnerable to damage, so this intervention helps protect the skin while maintaining the client's comfort during the course of treatment.

Correct Answer: A

Rationale: Essential thrombocythemia (ET) is a myeloproliferative disorder characterized by an abnormally high platelet count, which increases the risk of hypercoagulation and thrombosis (blood clot formation). These clots can impair blood flow to tissues, leading to ineffective tissue perfusion. Thrombotic events, such as strokes, deep vein thrombosis, or myocardial infarctions, are common complications of ET, making Risk for Ineffective Tissue Perfusion the most critical nursing diagnosis to prioritize. The goal of nursing interventions will be to prevent clot formation and ensure adequate blood flow to tissues.

Correct Answer: D

Rationale: While chemotherapy does affect normal, healthy cells-particularly those that divide rapidly-it is not "more likely" to kill normal cells compared to cancer cells. Chemotherapy targets rapidly dividing cells, which includes both cancer cells and some normal cells (like those in hair follicles, the gastrointestinal tract, and bone marrow). However, its primary goal is to kill cancer cells, and its effects on normal cells are a side effect, not the main function. Therefore, the statement that chemotherapy is "more likely" to kill normal cells is inaccurate and indicates a need for further teaching.

Correct Answer: B

Rationale: The best time to perform a testicular self-examination (TSE) is after a warm shower or bath. The heat from the water relaxes the scrotal skin, making it easier to feel any abnormalities, lumps, or changes in the testicles. This relaxation allows for a more thorough and accurate examination.

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.
