Correct Answer: A

Rationale: The correct answer is A because avoiding environmental allergens and cold air can help prevent asthma attacks. This shows the patient understands the importance of managing triggers. Choice B is incorrect because over-the-counter medications may not be sufficient for asthma management. Choice C is incorrect because smoking can worsen asthma symptoms. Choice D is incorrect because using the inhaler only when feeling short of breath is not a proactive approach to managing asthma triggers.

Correct Answer: A

Rationale: The correct answer is A: Psoriasis. Psoriasis is characterized by red, scaly patches on the skin, which align with the symptoms described. Psoriasis commonly affects the lower legs and is associated with severe itching. Eczema (choice B) is characterized by red, inflamed, and itchy skin patches, but typically presents differently from psoriasis. Contact dermatitis (choice C) is a localized reaction that occurs when the skin comes into contact with an irritant or allergen, and fungal infections (choice D) typically present with itching, redness, and sometimes peeling skin, but not necessarily scaly patches like psoriasis.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. ARDS is characterized by severe hypoxemia, and oxygen therapy is essential to improve oxygenation. Administering corticosteroids (B) is not recommended as they do not improve outcomes in ARDS. Monitoring serum glucose (C) is unrelated to the treatment of ARDS. Administering pain relief (D) is important for patient comfort but does not address the underlying hypoxemia in ARDS. Oxygen therapy is the primary treatment to support respiratory function and improve oxygen delivery in ARDS.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. Oxygenation is the priority in stroke management to ensure adequate oxygen supply to the brain. Oxygen therapy can help reduce hypoxia, which is crucial in the acute phase of a stroke. Administering aspirin (B) is important but comes after ensuring oxygenation. Administering thrombolytics (C) requires proper assessment and diagnostic confirmation, not an immediate priority. Placing the client in a supine position (D) may worsen stroke symptoms if there is compromised blood flow, so it is not recommended as the initial action.

Correct Answer: B

Rationale: The correct answer is B: Monitoring serum albumin levels. This is because serum albumin is a protein synthesized by the liver that reflects long-term protein intake and overall nutritional status. Low levels indicate malnutrition or inflammation. Obtaining a dietary history (choice A) is important but may not always reflect the actual nutritional status. Monitoring weight (choice C) is helpful but may not provide a comprehensive view of the client's nutritional status. Providing a meal plan (choice D) is a proactive approach but does not directly assess the client's current nutritional status.
