Correct Answer: C

Rationale: Rationale: Choice C, apply ice, is the correct answer as the first intervention for a client at risk for dehydration. Applying ice helps to lower the body temperature, which can reduce sweating and fluid loss. This intervention is crucial in preventing further dehydration. Administering IV fluids (Choice A) may be necessary in severe dehydration cases, but it is not the first intervention. Administering oxygen (Choice B) is not directly related to dehydration. Elevating the leg (Choice D) is not effective in addressing dehydration. In summary, applying ice is the most appropriate initial intervention to prevent dehydration by reducing body temperature and fluid loss.

Correct Answer: A

Rationale: Step 1: Stop the transfusion - Febrile reaction can indicate a transfusion reaction, so stopping the transfusion is crucial. Step 2: Administer antipyretics - To reduce fever and prevent further complications. Step 3: Assess for other signs of transfusion reaction - Such as chills, rash, or hypotension. Summary: Option A is correct as it addresses the immediate need to stop the transfusion and manage the fever. Options B, C, and D do not prioritize stopping the transfusion, which is crucial in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Tenderness, warmth, and swelling at the site. Post-operative wound infection often presents with localized tenderness, warmth, and swelling due to inflammation and immune response. Redness, heat, and purulent drainage (choice A) can also indicate infection but are not specific to wound infections. Excessive swelling and redness (choice C) may be present in inflammatory responses but do not specifically point to an infection. Fever, chills, and nausea (choice D) can be systemic signs of infection but are not specific to wound infections. Tenderness, warmth, and swelling are more indicative of a localized wound infection.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. This is the most important intervention for a client with an obstructed airway because it helps to ensure that the patient is receiving adequate oxygen supply to prevent hypoxia. Oxygen therapy can help maintain oxygen saturation levels and support proper gas exchange in the lungs. Monitoring respiratory rate (B) is important but not as critical as ensuring oxygen supply. Administering morphine (C) is contraindicated as it can depress respiratory function further. Administering fluids (D) is not the priority in managing an obstructed airway.

Correct Answer: A

Rationale: The correct answer is A: Assess airway. In caring for a client with a traumatic head injury, the first priority is to ensure there is a clear airway to maintain oxygenation and ventilation, which is crucial for brain function. If the airway is compromised, it can lead to hypoxia and further brain damage. Providing pain relief (B) is important but not the immediate priority. Monitoring intracranial pressure (C) is essential but comes after ensuring a patent airway. Maintaining a quiet environment (D) can help reduce stimulation, but it is not as critical as assessing the airway for immediate intervention.
