Rationale: The correct answer is to instruct the client to seek treatment for the sarcoma immediately. Ewing's sarcoma is an aggressive cancer, and prompt treatment is crucial for improving prognosis. Option A is incorrect because while pain management is important, addressing the underlying cause (sarcoma) is the priority. Option B is not as critical as seeking treatment for the sarcoma itself. Option C is not the most important instruction as the primary concern is addressing the cancer diagnosis.

Correct Answer: D

Rationale: The correct answer is D: "Ginseng can increase blood pressure, which is a concern for clients with hypertension." Choice A is incorrect because ginseng does not typically decrease the effectiveness of blood pressure medication. Choice B is incorrect as stopping ginseng while on blood pressure medication may not be necessary. Choice C is not the most direct concern related to ginseng use in a hypertensive client, making it less relevant than the correct answer.

Correct Answer: C

Rationale: Understanding what losses the client recently experienced is crucial for the nurse in developing a therapeutic relationship. This information helps the nurse comprehend the client's emotional state, the potential triggers for the self-harm behavior, and provides insights into the client's current psychological and social challenges. Choice A, the family's reaction, may be important but is secondary to understanding the client's own experiences. Choice B, the nurse's feelings, is not relevant as the focus should be on the client. Choice D, why the client attempted suicide, is important but delving into recent losses can provide a broader context for the client's emotional distress and suicidal behavior.

Correct Answer: A

Rationale: In this situation, the priority action for the nurse is to apply a sterile saline dressing to the wound. This helps prevent infection and keeps the wound moist, which is crucial in promoting healing and preventing further complications. Option B, notifying the healthcare provider, is important but should come after addressing the wound. Administering pain medication (Option C) may be necessary but is not the first action to take in this emergency situation. Covering the wound with an abdominal binder (Option D) is not appropriate and may cause further harm by applying pressure to the protruding bowel.

Correct Answer: B

Rationale: To calculate the correct dosage, first, determine the total daily dose: 1.5 grams = 1500 mg. Since the medication is 200 mg/5 ml, for 1500 mg, the nurse needs to administer 1500/200 = 7.5 times the 5 ml dose. Therefore, 7.5 x 5 ml = 37.5 ml total daily dose. To administer this every 8 hours, divide 37.5 ml by 3 (8 hours intervals in a day) to get 12.5 ml to be administered every 8 hours. Choice A, C, and D are incorrect as they do not reflect the correct calculation of the dose based on the prescription and the available concentration.
