Correct Answer: C

Rationale: The correct statement is that Brachytherapy is an internal radiation therapy. Brachytherapy involves placing radioactive sources inside or near the tumor, delivering a high radiation dose to the targeted area while minimizing exposure to surrounding healthy tissues. Choices A and B are incorrect because pregnant nurses should not administer radiation therapy and brachytherapy does not make the patient radioactive. Choice D is incorrect as feces is not a source of radiation in teletherapy, and it does not require special disposal.

Correct Answer: B

Rationale: Arm edema on the operative side (lymphedema) is a known complication after a mastectomy. This can indicate impaired lymphatic drainage, leading to fluid accumulation in the arm. Pain at the incision site is expected postoperatively and may not necessarily indicate a complication. Sanguineous drainage in the Jackson-Pratt drain is a common finding in the immediate postoperative period. Complaints of decreased sensation near the operative site could be related to nerve damage or surgical manipulation, but it is not a typical complication after a mastectomy.

Correct Answer: A

Rationale: The correct answer is A: Bowel sounds. Checking for bowel sounds is crucial before administering any diet to ensure the gastrointestinal tract is functioning properly following surgery. This assessment helps prevent complications such as paralytic ileus. Choices B, C, and D are not the priority in this situation. While the ability to ambulate, incision appearance, and urine specific gravity are important assessments, ensuring bowel function takes precedence in this postoperative scenario.

Correct Answer: D

Rationale: The correct answer is D because the statement 'Chemotherapy is effective in killing all cancer cells' is incorrect. Chemotherapy does not kill all cancer cells and is not the same as radiation therapy. Chemotherapy targets rapidly dividing cells, including cancer cells, but it may not kill every single cancer cell. It is important for the student nurse to understand and communicate this distinction to the patient. Choices A, B, and C provide accurate information about teletherapy, brachytherapy, and chemotherapy, respectively, and do not require additional teaching.

Correct Answer: B

Rationale: The most appropriate response for a patient presenting with a firm, painless cervical lymph node and denying recent infectious diseases is to promptly refer the patient for medical assessment. This is crucial to rule out serious underlying conditions such as malignancy or other concerning causes. Calling 911 is not necessary in this situation as it is not an emergency. Ordering a radiograph may not be the most immediate or appropriate action, as further evaluation by a healthcare provider is needed first. Encouraging the patient to wait and track the lymph node for a week is not advisable when a potential serious condition needs to be ruled out promptly.
