A nurse is preparing to administer an IM injection to a client using a medication from an ampule. Which of the following actions should the nurse plan to take?

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.

B. This range represents the normal serum magnesium level. It is important for maintaining neuromuscular function and other vital processes in the body.

A. This range is too low for normal serum magnesium levels. Magnesium levels below this range can indicate hypomagnesemia, which can lead to symptoms such as muscle cramps, tremors, and cardiac arrhythmias.

C. This range is too high for normal serum magnesium levels. Elevated magnesium levels (hypermagnesemia) can occur in conditions such as renal failure or excessive magnesium intake, leading to symptoms like weakness, decreased reflexes, and in severe cases, cardiac arrest.

D. While this range is broader and includes the correct normal range (1.3-2.1 mEq/L), it also includes values that are below and above normal. Values below 1.3 mEq/L can indicate hypomagnesemia, while values above 2.1 mEq/L can indicate hypermagnesemia.
