Rationale: Hypovolemic shock in children is most frequently caused by blood loss, which can result from trauma, surgery, or gastrointestinal bleeding. Sepsis and anaphylaxis can lead to different types of shock (septic and anaphylactic), and heart failure is related to cardiogenic shock.

Correct Answer: C

Rationale: The correct answer is C. By age 5, children should be able to state their name and address. If a child cannot do this, it may indicate a developmental delay that requires further assessment. Choices A, B, and D do not indicate a need for further education as they reflect typical developmental milestones for preschool-age children, such as gradually improving counting skills, asking many questions, and improving speech clarity over time.

Correct Answer: A

Rationale: The correct answer is A: Neuroblastoma. Neuroblastoma, a cancer that arises from nerve tissue, is associated with increased levels of catecholamine metabolites, including VMA and HVA, in the urine. Nephroblastoma (Wilms tumor) is a type of kidney cancer and is not typically associated with elevated levels of catecholamine breakdown products. Leukemia is a cancer of the blood and bone marrow and does not lead to increased VMA and HVA excretion in urine. Osteosarcoma is a bone cancer and is not linked to elevated levels of catecholamine metabolites in the urine.

Correct Answer: C

Rationale: Withdrawing and discarding a sample equal to the amount of fluid in the device ensures that the blood drawn is not diluted by the IV fluids, providing accurate lab results.

Correct Answer: A

Rationale: The correct answer is A. The use of placebos without the patient's consent is unethical and goes against the principles of beneficence and autonomy. Choice B is incorrect because using placebos does not provide reliable information about the presence or severity of the pain; it only indicates the response to the placebo itself. Choice C is wrong as the absence of a response to a placebo does not definitively mean that the child's pain has an organic basis; there could be various reasons for the lack of response. Choice D is also incorrect as individuals may have a positive response to a placebo even if their pain has a significant organic cause. Therefore, the most appropriate response is A, emphasizing the ethical concerns surrounding the use of placebos without informed consent.
