Which intervention for treating croup at home should be taught to parents?

Choice A reason: This is not correct because the mother's action is not intended to calm or punish the child for having a tantrum. It is a traditional healing method that aims to restore the balance of energy in the body.

Choice B reason: This is correct because the mother's action is a form of folk medicine known as coining or cao gio. It involves rubbing a coin or a spoon on the skin with oil or ointment to create red marks or bruises. It is believed to release the wind or bad energy that causes illness or pain.

Choice C reason: This is not correct because the mother's action is not a form of discipline or correction. It is a way of showing care and concern for the child's well-being.

Choice D reason: This is not correct because the mother's action is not abusive or harmful. It is a cultural practice that is based on a different understanding of health and disease. It may look alarming to outsiders, but it is not intended to hurt or injure the child.

Choice A reason: Calling the physician is not the first action because it would delay the immediate intervention of oxygen administration, which is critical for a patient with hypoxia. The physician should be notified after initiating oxygen therapy and assessing the patient's condition.

Choice B reason: Placing the patient on 10 L/min oxygen per nasal cannula is not the first action because it is too high of a flow rate for a two-year-old patient, and it could cause oxygen toxicity or barotrauma. The appropriate oxygen delivery device and flow rate should be determined based on the patient's age, weight, and clinical status.

Choice C reason: Assessing the patient is not the first action because it would also delay the immediate intervention of oxygen administration. The patient's pulse oximetry reading indicates severe hypoxia, which requires prompt treatment to prevent organ damage or death. The patient should be assessed after initiating oxygen therapy and monitoring vital signs.

Choice D reason: Administering oxygen and monitoring vital signs while calling the physician is the correct answer because it provides the most effective and timely response to the patient's hypoxia. Oxygen administration improves the patient's oxygen saturation and tissue perfusion, while vital sign monitoring helps to evaluate the patient's response to therapy and identify any complications. Calling the physician informs them of the situation and allows them to order further interventions or tests as needed.
