Which of the following is true of body language?

C: Body language is crucial in communication as it conveys emotions and intentions. D: Body language can be both conscious and unconscious, depending on the situation.

Correct Answer: B

Rationale: The correct answer is B because encouraging the use of eyeglasses and hearing aids can improve the resident's ability to see and hear, potentially reducing confusion. This addresses sensory deficits commonly seen in the elderly. Providing alone time (A) may increase feelings of isolation. Limiting introductions (C) can worsen confusion. Turning up volume (D) may overwhelm the resident.

Correct Answer: D

Rationale: The correct answer is D: The NA should report unsafe situations or people to a supervisor. This is the correct answer because it emphasizes the importance of prioritizing safety in the workplace. By reporting unsafe situations or people, the nursing assistant can help prevent potential harm to themselves and others. It also demonstrates professionalism and adherence to ethical standards. Choice A is incorrect because keeping valuable belongings locked up does not directly relate to protecting oneself while working in a facility. Choice B is incorrect because sharing residents' information with friends violates confidentiality and can lead to legal consequences. Choice C is incorrect because limiting visitors in a resident's room does not necessarily protect the nursing assistant from potential risks within the facility.

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. When struck, the tuning fork produces a specific frequency of sound waves that can be used to assess a patient's ability to hear different pitches. The vibrations from the tuning fork are transmitted through bone conduction, allowing the healthcare provider to determine the patient's hearing acuity. Incorrect choices: A: Tongue depressor - This is used to hold down the tongue to allow for examination of the mouth and throat, not for testing hearing. B: Reflex hammer - This is used to test reflexes by striking tendons, not for testing hearing. C: Otoscope - This is used to examine the ear canal and eardrum, but not specifically for testing hearing with vibrations.

Correct Answer: C

Rationale: The correct answer is C: Safety belts. Safety belts on a stretcher help secure the person in place and prevent them from falling off or getting injured during transportation. Safety stirrups are used for medical procedures involving the legs, safety sheets are used for patient lifting and transferring, and safety trays are typically used for carrying medical supplies. Therefore, C is the most appropriate choice for safety devices specifically designed to protect the person on the stretcher.
