A nurse is planning to insert a peripheral IV catheter for an older adult client. Which of the following actions should the nurse plan to take?

The correct answer is A: Insert the catheter at a 45-degree angle. When inserting a peripheral IV catheter for an older adult client, the nurse should aim to insert the catheter at a 45-degree angle to reduce the risk of complications such as infiltration. Inserting at this angle helps to ensure proper placement in the vein and reduces the likelihood of the catheter slipping out or causing discomfort to the client. Placing the client's arm in a dependent position (B) is not necessary and could potentially cause unnecessary discomfort. Shaving excess hair from the insertion site (C) is not recommended as it can irritate the skin and increase the risk of infection. Initiating IV therapy in the veins of the hand (D) may not be the best choice for an older adult client due to potential fragility of hand veins and difficulty with vein accessibility.
