Which of the following is true of residents who have angina?

Correct Answer: A

Rationale: Step 1: Angina is chest pain or discomfort caused by reduced blood flow to the heart muscle. Step 2: Emotional distress can trigger angina episodes, so reducing distress is important. Step 3: Managing stress can help prevent angina attacks and improve overall well-being. Step 4: Choice A is correct because emotional distress can worsen angina symptoms. Summary: Choice B is incorrect because only healthcare professionals can administer nitroglycerin. Choice C is incorrect because large meals can strain the heart and worsen angina. Choice D is incorrect because while exercise is important, it should be done in moderation for angina patients.

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.

Correct Answer: C

Rationale: The correct answer is C, Scope of practice. The scope of practice defines the roles, responsibilities, and tasks that nursing assistants are legally allowed to perform. It is set by state or federal laws to ensure patient safety and quality care. A procedure manual (A) typically outlines specific steps for performing tasks but does not specify legal limitations. A cover letter (B) is a document used in job applications and is not related to defining nursing assistant tasks. Choice D is not provided.
