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: A

Rationale: The correct answer is A. Secondary MDS can occur at any age and results from prior toxic exposure to chemicals, including chemotherapeutic medications. Asking about exposure to toxic chemicals in previous jobs directly addresses the potential etiology of this patient's health problem. Choices B, C, and D are not as directly related to the etiology of secondary MDS. Recurrent infections (Choice B) are not a known cause of MDS. Family history (Choice C) is more pertinent to primary MDS, which has a genetic component, while sun exposure (Choice D) is not associated with the etiology of MDS.

Correct Answer: C

Rationale: For patients experiencing difficulties with oral intake, the provision of small, easily chewed meals may be beneficial. Option A (TPN) and B (PEG tube placement) are more invasive interventions and should be considered if non-oral routes are necessary. Option D is not appropriate as the primary responsibility for a patient's nutrition should lie with healthcare professionals to ensure proper management and monitoring.

Correct Answer: C

Rationale: The correct answer is C: Muscle weakness. In patients with multiple myeloma who have developed hypercalcemia, monitoring for muscle weakness is crucial. Hypercalcemia can lead to muscle weakness due to its effects on neuromuscular function. Choice A, increased heart rate, is more commonly associated with conditions like dehydration or anxiety rather than hypercalcemia. Choice B, decreased urine output, is commonly seen in conditions leading to acute kidney injury rather than hypercalcemia. Choice D, hypertension, is not a typical symptom of hypercalcemia and is more commonly associated with other conditions like uncontrolled high blood pressure.

Correct Answer: B

Rationale: The patient's signs of ecchymoses and petechiae are suggestive of thrombocytopenia, which is a common complication of leukemia. Thrombocytopenia is a condition characterized by a low platelet count, leading to abnormal bleeding. Checking the patient's most recent platelet level is crucial to assess the severity of thrombocytopenia and guide further interventions. Initiating measures to prevent venous thromboembolism (VTE) (Choice A) is not directly related to the patient's current signs. Placing the patient on protective isolation (Choice C) is not necessary for ecchymoses and petechiae. Ambulating the patient (Choice D) is not appropriate without addressing the underlying cause of abnormal bleeding.
