Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. This is the priority intervention because severe dehydration requires immediate fluid replacement to restore fluid balance and prevent further complications. IV fluids are the most rapid and effective way to rehydrate a severely dehydrated client. Monitoring vital signs (B) and blood pressure (D) are important, but administering IV fluids takes precedence. Encouraging oral fluids (C) may not be sufficient for a client with severe dehydration who may not be able to adequately absorb fluids orally.

Correct Answer: B

Rationale: The correct answer is B: Hypertrophic scar. This type of scar is raised, red, and irregular, but it does not extend beyond the boundaries of the original wound like a keloid. A keloid is characterized by excessive scar tissue that grows beyond the wound site. Contracture is a scar that causes tightening of the skin and may restrict movement. Stretch marks, on the other hand, are not raised or irregular like the described scar.

Correct Answer: A

Rationale: The correct answer is A because broccoli, oranges, and dark greens are rich in essential nutrients like vitamin C, antioxidants, and phytochemicals that boost the immune system and help prevent diseases. Broccoli contains sulforaphane, which has been shown to have anti-cancer properties. Oranges are high in vitamin C, crucial for immune function. Dark greens like spinach and kale are packed with vitamins and minerals that support overall health. Choice B is incorrect because no single food can cure many diseases. Choice C is incorrect because relying solely on vitamin pills may not provide all the necessary nutrients and benefits of whole foods. Choice D is incorrect as there is no scientific evidence supporting the concept of balancing body molecules through food.

Correct Answer: A

Rationale: The correct answer is A: Administer anticoagulants. Anticoagulants are the primary treatment for DVT as they prevent blood clots from getting bigger and reduce the risk of new clots forming. This helps prevent complications like pulmonary embolism. Elevating the leg and applying compression (option B) can help with symptoms but do not address the underlying cause. Providing anticoagulant therapy (option C) is similar to the correct answer but lacks specificity. Applying compression stockings (option D) can help prevent complications but do not treat the existing clot.

Correct Answer: A

Rationale: The correct answer is A: Use a numeric pain scale. This method allows for quantitative assessment of pain intensity, aiding in accurate pain management. It is widely used in healthcare settings, providing a standardized way to communicate and monitor pain levels. Visual analog scale (B) is subjective and less precise than numeric scales. Facial expression scale (C) may be influenced by cultural factors and is subjective. Observing for signs of depression (D) is important but not specific to assessing pain intensity.
