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

- A. Incorrect. The nurse should check the functioning of oxygen equipment daily, not weekly, to ensure safety and proper delivery of oxygen.

- B. Correct. The nurse should instruct the client to wear clothing made with cotton fabrics while oxygen is in use, as synthetic fabrics can generate static electricity and cause sparks that could ignite the oxygen.

- C. Incorrect. The nurse should instruct the client to avoid petroleum-based lubricants, such as Vaseline, as they are flammable and could cause burns if exposed to oxygen. The nurse should recommend water-soluble lubricants, such as K-Y jelly, instead.

- D. Incorrect. The nurse should instruct the client to store full oxygen tanks upright, not on their side, to prevent them from rolling and damaging the valve or regulator.

• A. Incorrect. Withholding pain medications for 24 hr after the old patch is removed is a harmful action that could cause severe withdrawal symptoms and uncontrolled pain for the client. The nurse should respect the client's right to refuse treatment and explore the reasons for their decision.
• B. Correct. Asking another nurse to witness the disposal of the new patch is a safe and legal action that follows the policies and procedures for handling controlled substances. The nurse should document the disposal of the new patch and report it to the appropriate authority.
• C. Incorrect. Sealing the patches in a plastic bag and placing them in the client's trash basket is an unsafe and illegal action that could lead to diversion, misuse, or accidental exposure of fentanyl to others. The nurse should dispose of the patches in a secure and designated container that prevents access by unauthorized persons.
• D. Incorrect. Sticking the two patches to each other and placing them in the sharps bin is an unsafe and improper action that could cause contamination, injury, or infection to others who handle or dispose of sharps waste. The nurse should dispose of the patches separately and carefully, avoiding contact with their adhesive surfaces.
