A nurse is teaching a client who is to begin chemotherapy about a peripherally inserted central catheter (PICC). Which of the following statements should the nurse include in the teaching?

Rationale: A. "We will change the dressing daily." The dressing for a PICC is typically changed every 7 days, or sooner if it becomes wet or soiled. Changing it daily is not necessary unless there is a specific indication for more frequent changes, such as infection or drainage. B. "We can measure your blood pressure in either arm." It is not recommended to measure blood pressure in the arm with the PICC line as this could increase the risk of complications, such as dislodging the catheter or causing discomfort. BP should be measured in the opposite arm. C. "We will replace the PICC every month." It is a long-term catheter, used for several months, unless there are complications or it needs to be replaced due to malfunction or infection. Regular assessments and care are necessary, but replacement is not routine monthly. D. "We can draw blood samples from the PICC for diagnostic tests." The PICC line is often used for drawing blood samples, as it provides easy access to the central venous system. Blood can be drawn from the PICC for diagnostic tests, which is one of its primary uses in chemotherapy patients.
