A second grader enters the school nurse's office crying and states, "I feel sick. My tummy hurts." The nurse replies, "I'll call your mommy or daddy to come pick you up." The child replies, "I don't have a mommy. I have two daddies." Which of the following comments by the nurse is appropriate?

Choice A reason: This is the most comprehensive and accurate way of assessing a child's pain, as it takes into account the child's own perception, the parent's observation, and the objective signs of pain.

Choice B reason: This is not the best approach, as the parents may not be able to accurately rate the child's pain, especially if the child is too young or has communication difficulties.

Choice C reason: This is not the best approach, as behavioral clues may not always reflect the intensity or quality of pain, and may be influenced by other factors such as fear, anxiety, or coping strategies.

Choice D reason: This is not the best approach, as physiological measures may not always correlate with pain, and may be affected by other variables such as medication, stress, or illness.

Choice A reason: This is the most appropriate action because it respects the youth's autonomy and maturity, and allows for timely and necessary intervention. Assent is the agreement of a minor to participate in a medical decision, and it is usually sufficient in emergency situations when parental consent is not available.

Choice B reason: This is not the most appropriate action because it may delay the surgery and put the youth at risk of further complications. Another relative may not have the legal authority to consent for the youth, and may not be reachable in time.

Choice C reason: This is not the most appropriate action because it does not address the underlying problem of the injury. Pain medications may provide temporary relief, but they may also mask the symptoms and interfere with the surgery.

Choice D reason: This is not the most appropriate action because it may jeopardize the youth's health and safety. Waiting for parents to obtain consent may result in irreversible damage or even death. The youth's best interest should be the priority in this case.
