A nurse is preparing to administer penicillin IM to an adult client. Which of the following angles should the nurse use for injection into the client's ventrogluteal muscle?

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.

C. This method is recommended because it is less painful, as the sides of the fingertips have fewer nerve endings compared to the pads or 'balls' of the fingers.

A. Avoiding the use of the thumbs is not necessary unless they are calloused or used frequently for other tasks that could affect sensitivity.

B. Avoiding the use of the dominant hand's fingers are not necessary unless they are calloused or used frequently for other tasks that could affect sensitivity.

D. Using the ball of the finger is not recommended for blood glucose monitoring because it can be more painful and may lead to less blood flow, resulting in difficulty obtaining an adequate blood sample.
