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.

A. Diarrhea is a common side effect associated with ondansetron, which is used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, and surgery.

B. Ondansetron can potentially cause changes in glucose metabolism, leading to hyperglycemia, especially in clients with diabetes mellitus. Monitoring blood glucose levels is essential during ondansetron administration, particularly in clients who are already predisposed to hyperglycemia.

D. Headache is a potential adverse effect of ondansetron. It is listed as a common side effect and should be monitored, especially in older adults who may be more sensitive to medication effects.

C. Ondansetron can affect the QT interval rather than the PR interval. It may cause QT interval prolongation, which can predispose the client to arrhythmias
