A nurse is teaching a client how to care for their behind-the-ear hearing aids. Which of the following statements by the client indicates an understanding of the teaching?

A. Changing the inner cannula on a tracheostomy: This procedure falls within the RN's scope of practice, as it involves basic tracheostomy care and maintenance, which nurses commonly perform.
B. Administering a platelet transfusion: Administering blood and blood products, including platelet transfusions, is within the RN's scope of practice, provided the nurse has appropriate training and competency.
C. Irrigation of an external ear canal: Irrigation of an external ear canal is a routine nursing procedure that falls within the RN's scope of practice, as long as it does not involve invasive procedures beyond irrigation.
D. Inserting a tunneled central venous catheter: Inserting tunneled central venous catheters is typically performed by advanced practice nurses or physicians with specific training and certification, such as nurse practitioners or interventional radiologists. This procedure is beyond the scope of practice for RNs and requires specialized skills and knowledge.

A. Attach a dosimeter to the client's gown: A dosimeter measures the radiation dose received by the wearer over a period of time. While healthcare providers and personnel working closely with the client during brachytherapy may wear dosimeters, attaching one to the client's gown is not a standard practice.
B. Strain the client's urine: Straining the client's urine is not directly related to the care required for a client undergoing brachytherapy. The primary focus of care during brachytherapy is to minimize radiation exposure to others and promote the client's comfort and safety.
C. Limit each of the client's visitors to 2 hr per day: While it may be appropriate to limit the duration of visits to reduce the potential radiation exposure of visitors, the specific time limit of 2 hours per day is not standard and should be determined based on individual circumstances and institutional policies.
D. Instruct visitors to stay 1 m (3.3 feet) away from the client: This intervention is appropriate because it helps minimize radiation exposure to visitors. Maintaining distance from the client reduces the risk of radiation exposure to others while still allowing for social interaction and support during the client's treatment.
