A 22-year-old dialysis patient presents to the ER with chest pain and palpitations. Laboratory tests reveal a Potassium (K+) level of 7.0 mEq/L. Which electrolyte imbalance is the patient suffering from?

A. IV solutions and administration sets should typically be changed every 48 to 72 hours to reduce the risk of contamination and infection. This interval helps prevent the buildup of bacteria in the solution and tubing, which could lead to bloodstream infections (BSIs).

B. Checking the client's IV site every is also important for monitoring for signs of infection, infiltration, or phlebitis. However, every 8 hours is too frequent and unnecessary

C. IV tubing should be changed every 72 hours not every 96 hours. Prolonging the use of IV tubing beyond this timeframe increases the risk of bacterial contamination and infection.

D. Transparent dressings are usually changed every 5 to 7 days, or sooner if they become soiled or compromised.

The nurse should first stop the infusion (D) to prevent further infiltration of the vesicant solution. Next, the nurse should attach a syringe to the catheter (E) to prepare for aspiration.

Following this, the nurse should aspirate the solution from the catheter (C) to remove as much of the vesicant as possible. After aspiration, the nurse should disconnect the tubing from the catheter (A), ensuring that no additional vesicant is administered. Finally, the nurse should remove the IV catheter (B) to prevent any further exposure to the vesicant.
