Correct Answer: A

Rationale: During the vascular stage of inflammation, there is an outpouring of exudate into the interstitial spaces, leading to swelling and edema. Choice B, chemotaxis, occurs during the cellular stage of inflammation, where leukocytes move to the site of injury in response to chemical signals. Choice C, accumulation of leukocytes along the epithelium, is not a typical event during the vascular stage. Phagocytosis of cellular debris, as in choice D, mainly occurs during the resolution stage of inflammation.

Correct Answer: C

Rationale: Alcohol impairs judgment and dulls mental awareness, making a person less likely to seek shelter when experiencing hypothermia. This impaired judgment can lead to risky behaviors that exacerbate the effects of cold exposure. Choice A is incorrect because alcohol does not directly interfere with the appetite center in the brain to the extent described. Choice B is incorrect as alcohol consumption does not directly impact the amount of body fat present. Choice D is incorrect because alcohol does not increase the basal metabolic rate but rather slows it down.

Correct Answer: A

Rationale: The correct answer is A. Statins like atorvastatin should be taken at night to reduce the risk of muscle pain and other side effects. Taking the medication with a high-fat meal (choice D) is not recommended as it can decrease the effectiveness of the medication. Alcohol consumption (choice C) should be moderated but does not need to be completely avoided unless contraindicated. Taking the medication with breakfast (choice B) may not be as effective as taking it at night due to the circadian rhythm of cholesterol synthesis.

Correct Answer: A

Rationale: The correct instruction for medroxyprogesterone acetate (Provera) is to take the medication at the same time each day to maintain consistent hormone levels and ensure its effectiveness. Choice B is incorrect because discontinuing the medication abruptly without consulting healthcare providers can be harmful. Choice C is incorrect as taking the medication with food is not necessary for this specific drug. Choice D is incorrect as medroxyprogesterone is typically taken orally, not applied topically.

Correct Answer: C

Rationale: The priority nursing intervention during an acute asthma exacerbation is to administer short-acting beta-agonists (SABAs) as prescribed. SABAs help in quickly relieving bronchospasm and are considered the first-line treatment for acute exacerbations. Administering corticosteroids, positioning the client, and obtaining a peak flow reading are important interventions but come after administering SABAs in the management of acute asthma exacerbation.
