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

Correct Answer: A

Rationale: The correct answer is A because residents with angina need to reduce emotional distress, as stress can trigger angina attacks. Providing emotional support and creating a calm environment can help manage symptoms. B is incorrect because only medical professionals can administer nitroglycerin. C is incorrect because large meals can worsen angina symptoms due to increased blood flow to the digestive system. D is incorrect because residents with angina need to balance rest and activity, and excessive exercise can trigger angina attacks.

Correct Answer: A

Rationale: The correct answer is A because skills used over a lifetime are typically retained longer in individuals with Alzheimer's disease due to the concept of cognitive reserve. This means that engaging in mentally stimulating activities throughout life can help delay cognitive decline. Choice B is incorrect as symptoms of AD can vary greatly among individuals. Choice C is incorrect as NAs should promote independence and provide assistance based on individual needs. Choice D is incorrect as Alzheimer's is not a normal part of aging but a neurodegenerative disease.

Correct Answer: A

Rationale: The correct answer is A because inspecting and cleaning the resident's feet daily helps in early detection of any cuts, sores, or signs of infection, which is crucial for diabetics to prevent complications. Clipping toenails frequently can lead to cuts and infections. Using lotion between the toes can create a moist environment that promotes fungal growth. Using hot water for bathing can cause burns and dry out the skin, increasing the risk of cracks and infections.

Correct Answer: C

Rationale: The correct answer is C: Blood oxygen level. A pulse oximeter measures the oxygen saturation level in the blood, indicating how well oxygen is being carried to the body's tissues. It does this by shining light through the skin to detect the amount of oxygen-bound hemoglobin in the blood. Choice A, blood pressure, is measured using a sphygmomanometer. Choice B, body temperature, is typically measured using a thermometer. Choice D, blood glucose level, is measured using a glucometer. Thus, the correct answer is C as it directly aligns with the function and purpose of a pulse oximeter.

Correct Answer: C

Rationale: The correct answer is C, Scope of practice. A scope of practice outlines the tasks nursing assistants can legally perform. It is based on state or federal regulations and ensures safe and effective care. A procedure manual (A) provides instructions for specific tasks but doesn't define legal boundaries. A cover letter (B) is a document used in job applications and is unrelated to task permissions. Option D is incomplete and irrelevant to the question.
