An emergency department nurse triages a group of school children injured in a school bus crash. Which of the following children should the nurse have the provider evaluate first?

A. Dependent edema may occur in some cases of pericarditis but is not typically a priority finding compared to chest pain, which can indicate cardiac compromise.

B. A pericardial friction rub is a classic finding in pericarditis but is not necessarily the priority over the chest pain, which requires immediate attention.

C. A paradoxical pulse (pulse amplitude decreasing during inspiration) can occur in pericarditis but is not typically as concerning as substernal chest pain.

D. Substernal chest pain is a common and significant symptom of pericarditis, and assessing and managing the pain is a priority to ensure adequate cardiac function and alleviate discomfort.

A. Using the injection port farthest from the IV catheter insertion site is not necessary for administering an IV bolus of medication and may not be practical depending on the setup of the IV tubing.

B. Occluding the IV tubing above the injection port prevents the bolus medication from flowing into the continuous IV infusion, ensuring that the medication is delivered directly to the patient.

C. Checking for blood return after medication administration is not relevant in this context, as albumin 5% is administered intravenously and does not require blood return.

D. Flushing the IV tubing with a heparinized solution is not necessary for administering an IV bolus of medication and may not be appropriate for all medications.
