The ______ is the outer layer of the skin which is composed of dead cells.

Correct Answer: B

Rationale: The correct answer is B: Epidermis. The epidermis is the outer layer of the skin and is composed of dead cells that continuously shed and are replaced by new cells. The integument (choice A) refers to the entire skin organ, not just the outer layer. The dermis (choice C) is the layer beneath the epidermis and contains blood vessels, nerves, and connective tissues. Melanocytes (choice D) are cells within the epidermis that produce the pigment melanin, responsible for skin color, but they are not the outer layer of the skin composed of dead cells.

Correct Answer: B

Rationale: Phantom sensation refers to feeling sensations in the amputated limb location. This happens due to the brain still receiving signals from the missing limb. Choice B is correct as it accurately describes this phenomenon. Choice A is incorrect as phantom sensation is a real experience. Choice C is incorrect as it refers to a different condition, while Choice D is incorrect as it does not relate to phantom sensation.

Correct Answer: A

Rationale: The correct answer, A, is true because skills used over a lifetime are typically stored in long-term memory, which is less affected by Alzheimer's disease. This allows individuals to retain those skills longer compared to newly acquired skills. Choice B is incorrect because residents with AD may exhibit different signs and symptoms at different times due to the progressive nature of the disease. Choice C is incorrect as NAs should encourage residents to perform tasks independently to maintain their sense of autonomy. Choice D is incorrect because Alzheimer's disease is not a normal part of aging but rather a neurodegenerative disorder.

Correct Answer: A

Rationale: Rationale for Choice A: - Inspecting and cleaning the resident's feet daily helps to identify any potential issues early on, such as cuts or sores. - Diabetic individuals are at a higher risk for foot complications, so regular monitoring is crucial to prevent infections. - Cleaning the feet daily can help maintain good hygiene and prevent issues from escalating. Summary of Incorrect Choices: - Choice B (clipping toenails frequently) can increase the risk of injury and infections if not done correctly. - Choice C (using lotion between toes) can trap moisture and lead to fungal infections. - Choice D (using hot water for bathing) can actually cause burns or dry out the skin, increasing the risk of injury.

Correct Answer: C

Rationale: The correct answer is C: Blood oxygen level. A pulse oximeter measures the oxygen saturation levels in the blood by analyzing the amount of oxygen carried by hemoglobin. Hemoglobin absorbs different amounts of light based on the level of oxygen it is carrying, allowing the device to determine the oxygen saturation. A: Blood pressure is incorrect as a pulse oximeter does not measure blood pressure. B: Body temperature is incorrect as a pulse oximeter does not measure body temperature. D: Blood glucose level is incorrect as a pulse oximeter does not measure blood glucose level.
