Correct Answer: B

Rationale: The correct answer is B because encouraging the use of eyeglasses and hearing aids can help improve the resident's ability to see and hear, potentially reducing confusion. This approach addresses sensory deficits commonly associated with confusion in older adults. Providing time alone (A) may increase feelings of isolation, limiting social interaction. Limiting self-introductions (C) can hinder building rapport and trust. Increasing electronic device volumes (D) might overwhelm the resident and exacerbate confusion.

Correct Answer: D

Rationale: The correct answer is D: The NA should report unsafe situations or people to a supervisor. This is important for the safety of both the nursing assistant and the residents. By reporting unsafe situations promptly, necessary actions can be taken to prevent harm. It also ensures a safe working environment for all staff members. A: Keeping valuable belongings locked up is important for personal safety but not directly related to protecting oneself while working in a facility. B: Sharing resident's information with friends violates resident confidentiality and is unethical. C: Limiting visitors in a resident's room is important for infection control, but it is not a direct way to protect the nursing assistant.

Correct Answer: D

Rationale: The correct answer is D: Tuning fork. A tuning fork is used during a physical exam to test hearing with vibrations by placing it on different parts of the body to assess hearing ability. The vibrations produced by the tuning fork help evaluate the patient's ability to hear different frequencies. A: Tongue depressor is used to hold down the tongue during a throat examination, not for testing hearing. B: Reflex hammer is used to test reflexes, not for hearing evaluation. C: Otoscope is used to examine the ear canal and eardrum, but not for testing hearing with vibrations.

They are essential for the safety of the individual being transported. Safety stirrups (A) are used for leg support during medical procedures, not for securing a person on a stretcher. Safety sheets (B) are used for patient transfer and positioning, not for securing them on a stretcher. Safety tray (D) is not a common safety device used on stretchers.
