The nurse is caring for an infant admitted with dehydration, irritability, signs of extreme hunger, and a palpable olive-like mass in the upper right abdominal quadrant. When feeding the infant, the nurse should monitor for which development?

Choice A reason: Having the child blow a cotton ball and have the parent catch it is not a good strategy to ensure the child's cooperation. This activity might distract the child from the assessment and make it difficult for the nurse to listen to the lung sounds.

Choice B reason: Allowing the child to use a stethoscope on a stuffed animal is a good strategy to ensure the child's cooperation. This activity helps the child to understand the purpose of the stethoscope and reduces the fear of the unfamiliar device. It also allows the nurse to observe the child's breathing pattern and chest movement.

Choice C reason: Offering the child bubbles before the stethoscope is placed is not a good strategy to ensure the child's cooperation. This activity might alter the child's breathing pattern and interfere with the accuracy of the assessment.

Choice D reason: Placing a toy in the child's hands while listening to the breath sounds is not a good strategy to ensure the child's cooperation. This activity might distract the child from the assessment and make it difficult for the nurse to listen to the lung sounds.

Choice A reason: Changing position every 2 hours is not the most important intervention that the nurse should implement. This is because the child's position is limited by the traction and the splint, and frequent repositioning may interfere with the alignment and stability of the fracture. The nurse should only change the position of the child as ordered by the physician and with the assistance of another nurse.

Choice B reason: Assessing skin for redness and signs of tissue breakdown is not the most important intervention that the nurse should implement. This is because the skin is not directly in contact with the traction or the splint, and the risk of pressure ulcers is low. The nurse should still inspect the skin regularly and provide skin care as needed, but this is not the priority.

Choice C reason: Cleansing pin sites as prescribed is not the most important intervention that the nurse should implement. This is because the pin sites are not the main source of infection or complication in this type of traction. The nurse should still follow the protocol for pin site care and monitor for signs of infection, such as redness, swelling, drainage, or odor, but this is not the priority.

Choice D reason: Monitoring peripheral pulses and sensation in the right leg is the most important intervention that the nurse should implement. This is because the traction and the splint can impair the circulation and nerve function of the affected extremity, leading to complications such as compartment syndrome, ischemia, or nerve damage. The nurse should check the pulses, temperature, color, capillary refill, and sensation of the right leg at least every hour and report any changes or abnormalities to the physician.
