What is the most effective action when a client with acute respiratory distress syndrome (ARDS) develops hypoxemia?

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. In ARDS, the primary issue is hypoxemia due to impaired gas exchange in the lungs. Administering oxygen helps to increase the oxygen levels in the blood, improving oxygenation to vital organs. Corticosteroids (B) are not indicated as they have not shown consistent benefit in ARDS treatment. Bronchodilators (C) are not effective as ARDS is not primarily a bronchoconstrictive disorder. Applying an ice pack to the chest (D) is not relevant and will not address the underlying hypoxemia. Administering oxygen is the most effective and essential intervention to correct hypoxemia in ARDS.

Correct Answer: A

Rationale: The correct answer is A - Administer IV fluids. This is the priority intervention for a client with suspected hypovolemia and hypotension as it helps to restore intravascular volume and improve blood pressure. IV fluids will address the underlying cause of hypotension by increasing circulating volume. Monitoring blood pressure (B) is important but administering IV fluids takes precedence. Administering corticosteroids (C) is not indicated for hypovolemia and hypotension. Administering oxygen (D) may be necessary if there is evidence of hypoxia, but addressing fluid volume status is the primary concern in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. The priority nursing action for a client with severe dehydration is to restore fluid volume to maintain vital organ function. Administering IV fluids is crucial in rapidly replenishing lost fluids and electrolytes. Corticosteroids (choice B) are not indicated for dehydration. Re-administering IV fluids (choice C) is redundant. Administering analgesics (choice D) is not a priority in the management of severe dehydration.

Correct Answer: A

Rationale: The correct answer is A: Cleanse and dress the wound. This intervention is essential as it helps prevent infection, promotes healing, and maintains a moist wound environment. Cleansing removes debris and bacteria, while dressing protects the wound from external contaminants. Administering antibiotics (choice B) is not the initial intervention for an open wound. Placing a sterile dressing (choice C) is important, but cleansing the wound first is crucial. Ensuring wound care is sterile (choice D) is important, but the primary focus should be on cleansing and dressing the wound.

Correct Answer: A

Rationale: The correct answer is A (Broccoli, oranges, dark greens) because these foods are high in soluble fiber, antioxidants, and plant sterols which are known to help lower cholesterol levels. Broccoli contains fiber that binds to cholesterol in the gut, oranges are rich in vitamin C and fiber, and dark greens like spinach and kale are packed with antioxidants and fiber. Option B (Fiber-rich foods) is partially correct as fiber can help reduce cholesterol levels, but it is not as specific as the foods mentioned in option A. Option C (Increase intake of omega-3 fatty acids) is not directly related to lowering cholesterol, although omega-3s have other health benefits. Option D (Eliminate fat-rich foods) is not ideal as not all fats are bad for cholesterol, and some healthy fats like those found in avocados and nuts can actually improve cholesterol levels.
