Correct Answer: A

Rationale: The correct answer is A: Ewald tube. This tube is used for gastric lavage due to its large diameter and open end which allows for effective suction of gastric contents. The Ewald tube is specifically designed for gastric lavage and is ideal for removing toxins from the stomach. Summary of why the other choices are incorrect: B: Dobhoff tube is a small-bore feeding tube, not suitable for gastric lavage. C: Miller-Abbott tube is used for intestinal decompression, not gastric lavage. D: Sengstaken-Blakemore tube is used for esophageal varices, not gastric lavage.

Correct Answer: A

Rationale: The correct answer is A because administering a lethal dose of medication to a patient whose death is imminent directly causes the patient's death, constituting assisted suicide. This action is intentional and aims to end the patient's life. In contrast, choices B, C, and D do not involve intentionally causing the patient's death. Choice B involves a medication error but not with the intent to end the patient's life. Choice C respects the patient's autonomy in refusing treatment. Choice D honors the patient's wishes for end-of-life care. Thus, only choice A aligns with the definition of assisted suicide.

Correct Answer: C

Rationale: The correct answer is C (900 mL) because the weight of 900 g corresponds to a blood loss of the same amount in milliliters. Blood density is close to that of water, so 1 g ? 1 mL. Therefore, a blood-soaked peripad weighing 900 g indicates a blood loss of 900 mL. Choice A (1800 mL) is incorrect as it doubles the weight instead of converting it to milliliters. Choice B (450 mL) is incorrect as it halves the weight. Choice D (90 mL) is incorrect as it divides the weight by 10, which is too small for the blood loss indicated.

Correct Answer: B

Rationale: The correct answer is B: Count and inspect each perineal pad that the patient uses. This method directly measures postoperative blood loss and allows for accurate monitoring. It provides quantitative data to assess the severity of hemorrhage. A: Having the patient void and have bowel movements using a commode rather than toilet does not directly measure blood loss and may not provide accurate monitoring. C: Swabbing the patient's perineum for the presence of blood is not as accurate as directly counting and inspecting perineal pads. D: Leaving the patient's perineum open to air does not provide a method for quantifying blood loss and may not be as reliable as inspecting perineal pads.

Correct Answer: C

Rationale: The correct answer is C: "You are anxious about the surgery. Do you see smoking as helping?" This response acknowledges the patient's anxiety and invites him to explore his reasons for wanting to smoke, opening up a dialogue and potentially uncovering underlying issues. It also avoids judgment or direct orders, fostering a therapeutic nurse-patient relationship. Explanation of why the other choices are incorrect: A: "Smoking is the reason you are here." - This response is blaming and may increase the patient's guilt or anxiety, hindering effective communication. B: "The doctor left orders for you not to smoke." - This response is authoritative and may lead to resistance or defensiveness from the patient, rather than addressing his concerns. D: "Smoking is OK right now, but after your surgery it is contraindicated." - This response is unclear and may send mixed messages to the patient, potentially leading to confusion or misunderstanding.
