Which of the following interventions promotes patient safety?

Correct Answer: D

Rationale: All the listed interventions are essential for promoting patient safety. Assessing the patient's ability to ambulate and transfer helps prevent falls, demonstrating the signal system ensures effective communication in emergencies, and checking the patient's identification band aids in accurate identification and treatment. By combining these interventions, healthcare providers can enhance patient safety and quality of care.

Correct Answer: C

Rationale: Patients with impaired awareness may exhibit symptoms such as being semiconscious, overfatigued, disoriented, confused, or demonstrating symptoms of drug or alcohol withdrawal. A patient who cannot care for themselves at home does not necessarily indicate impaired awareness, as this could be due to physical limitations or lack of support, rather than a cognitive deficit.

Correct Answer: D

Rationale: Hip fracture is the most common injury among elderly persons. As people age, their bones become more fragile, making them more susceptible to hip fractures, often resulting from falls. These fractures can significantly impact an elderly person's quality of life and mobility, making them a significant concern in geriatric care.

Correct Answer: A

Rationale: Depression is the most common psychogenic disorder among elderly individuals. It can manifest as persistent feelings of sadness, hopelessness, and loss of interest in activities that were once enjoyed. Elderly individuals may also experience changes in appetite, sleep disturbances, and difficulty concentrating. Detecting and addressing depression in the elderly is crucial for their overall well-being and quality of life.

These changes include increased peripheral resistance of the blood vessels, decreased blood flow, and an increased workload of the left ventricle. Therefore, all the listed changes result from aging, making option D, 'All of the above,' the correct answer.
