A nurse is performing a skin assessment for a client who is on bedrest. Which of the following actions should the nurse take to prevent a pressure injury?

A. Dependent edema can occur with pericarditis but does not indicate an immediate life-threatening complication.
B. A pericardial friction rub is a common finding in pericarditis and helps confirm the diagnosis but is not the priority.
C. A paradoxical pulse (an exaggerated decrease in systolic blood pressure during inspiration) is a sign of cardiac tamponade, a life-threatening complication of pericarditis, and requires immediate intervention.
D. Substernal chest pain is expected with pericarditis and is usually relieved by sitting up and leaning forward, but it is not the most urgent concern.

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.
