Correct Answer: B

Rationale: The correct answer is B: Pernicious anemia. This condition is characterized by a deficiency in vitamin B12, leading to neurological symptoms like tingling sensations in the feet (peripheral neuropathy) and glossitis, causing the tongue to become red and painful. Polycythemia (A) is an increase in red blood cell mass, not related to the symptoms described. Micronucleus anemia (C) is not a recognized medical condition. Iron-deficiency anemia (D) can lead to symptoms like fatigue and pallor, but not typically tingling sensations in the feet or glossitis.

Correct Answer: A

Rationale: The correct answer is A: Light therapy. Light therapy is effective for treating sleep problems, stress, and seasonal affective disorders because exposure to bright light can regulate circadian rhythms, improve mood, and alleviate symptoms associated with these conditions. Light therapy helps reset the body's internal clock, promoting better sleep patterns and reducing stress. Exercise (choice B) can also improve sleep and reduce stress, but it may not specifically target seasonal affective disorders. Medication (choice C) and herbal treatments (choice D) are not typically recommended as the first-line treatment for these conditions and may have side effects or limited efficacy compared to light therapy.

Correct Answer: C

Rationale: The primary purpose of an abdominal binder after surgery is to increase circulation. An abdominal binder helps improve blood flow to the surgical site, which can aid in reducing swelling, promoting healing, and preventing complications such as blood clots. It provides gentle compression to support the abdominal muscles and tissues without restricting circulation. Choice A (Promote comfort) is incorrect because while an abdominal binder may provide some comfort by supporting the abdomen, its primary purpose is not solely for comfort. Choice B (Prevent infection) is incorrect because an abdominal binder does not directly prevent infection. Infection prevention is primarily achieved through proper wound care and infection control practices. Choice D (Provide wound care) is incorrect because an abdominal binder does not provide wound care. Wound care involves cleaning, dressing changes, and monitoring for signs of infection, which are separate from the purpose of an abdominal binder.

Correct Answer: A

Rationale: Step-by-step rationale: 1. High HDL cholesterol is considered beneficial as it helps remove LDL cholesterol from arteries, reducing the risk of plaque buildup. 2. Low HDL cholesterol is associated with an increased risk of cardiovascular disease. 3. Low total cholesterol may not necessarily indicate a decreased risk, as it could be due to low levels of protective HDL cholesterol. 4. Low triglycerides, while generally considered good, do not directly indicate a decreased risk of cardiovascular disease like high HDL cholesterol does. In summary, high HDL cholesterol is the correct answer as it plays a crucial role in reducing the risk of cardiovascular disease by removing LDL cholesterol, whereas the other choices do not offer the same protective benefits.

Correct Answer: C

Rationale: The correct answer is C: large-census metropolitan areas. This is supported by the fact that large cities like Toronto, Montreal, and Vancouver attract the most immigrants due to job opportunities, diverse communities, and cultural amenities. These cities offer better infrastructure and services compared to smaller areas, making them more appealing for settlement. Choices A and B are incorrect because smaller areas may lack the resources and opportunities that large cities provide. Choice D is incorrect as extremely large cities might be overwhelming and less conducive to successful integration for newcomers. Therefore, the majority of immigrants settling in Canada choose large-census metropolitan areas for better prospects and quality of life.
