Correct Answer: D

Rationale: The correct answer is D: Hold the breath for at least 5 seconds after inhaling the medication. Holding the breath after inhaling the medication allows for better absorption of the medication into the lungs. This helps ensure the medication reaches the target area for optimal effectiveness. Exhaling deeply before using the inhaler (Choice A) is not necessary and can actually reduce the amount of medication reaching the lungs. Using the inhaler only when asthma symptoms are severe (Choice B) is not recommended as it is important to use the inhaler as prescribed by the healthcare provider. Inhaling deeply while activating the inhaler (Choice C) is important, but holding the breath after inhaling the medication is crucial for optimal medication delivery.

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.

Correct Answer: C

Rationale: The correct answer is C: Assessing for signs of infection. This is the priority because diabetic foot ulcers are at high risk for infection, which can lead to serious complications. By assessing for signs of infection such as redness, warmth, swelling, pus, or foul odor, the nurse can promptly identify and initiate appropriate treatment. Administering antibiotics (A) should be based on the assessment findings. Providing pain relief (B) is important but not the priority when infection is a concern. Encouraging weight-bearing activity (D) may worsen the ulcer and should be avoided initially.

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: A

Rationale: The correct answer is A: Administer IV fluids. The initial priority in managing sepsis is to restore perfusion and oxygenation by giving IV fluids to support blood pressure and organ perfusion. This helps to improve tissue oxygenation and prevents further organ damage. Administering insulin (choice B) is not the priority in the initial management of sepsis. Monitoring blood pressure (choice C) is important but not the first step in the management of sepsis. Administering insulin is also listed twice and is not relevant to the immediate management of sepsis.
