One normal age-related change for the respiratory system is

Correct Answer: C

Rationale: The correct answer is C: Oxygen in the blood decreases. As people age, lung function declines, leading to reduced oxygen intake and exchange in the bloodstream. This is a normal age-related change due to decreased lung elasticity and efficiency. Choice A is incorrect as air sacs typically decrease in number and size with age. Choice B is incorrect because chest muscles tend to weaken, not strengthen, as individuals age. Choice D is also incorrect since lung capacity tends to decrease with age due to changes in lung tissue and decreased respiratory muscle strength.

Correct Answer: A

Rationale: The correct answer is A: Biopsy. A biopsy involves removing a sample of tissue for analysis and diagnosis. This procedure helps in identifying diseases or conditions. Arthroscopy (B) is a minimally invasive surgical procedure to visualize and treat joint problems. Telemetry (C) is a method of monitoring and transmitting data wirelessly. Bronchoscopy (D) is a procedure to visualize the airways in the lungs, not specifically for tissue sampling. In conclusion, only a biopsy involves tissue removal for diagnostic purposes.

Correct Answer: A

Rationale: The correct answer is A because it involves a physical cue that directly assists the resident in completing a task independently. By guiding the resident's hand to bring food to their mouth, the NA is providing a tangible, hands-on support that promotes independence. This type of cue helps the resident learn the physical movement required for eating and encourages self-reliance. Choices B, C, and D do not involve physical cues that directly assist the resident in performing the task. B involves verbal prompting, C involves verbal instruction after the fact, and D involves listing steps without providing physical assistance. These options do not offer the same level of immediate, hands-on support as choice A does.

Correct Answer: A

Rationale: Step-by-step rationale for why choice A is correct: 1. The dying person's right to be free from pain is a fundamental aspect of compassionate care. 2. Receiving pain medication when needed ensures the person's comfort and dignity in their final moments. 3. Pain management is a key component of palliative care to improve quality of life. 4. By providing pain medication when needed, the person's suffering can be alleviated, promoting a peaceful transition. Summary: Choice A is correct because it aligns with the ethical principle of beneficence by prioritizing the dying person's well-being and dignity. Choices B, C, and D are incorrect as they disregard the person's right to pain relief, lack empathy, and fail to address the person's physical comfort.
