A nurse would suspect an inhalation injury with which of the following findings? Select all that apply.

Correct Answer: A

Rationale: The correct answer is A because a history of burn occurring in an enclosed space can lead to inhalation of toxic fumes causing an inhalation injury. Carbonaceous sputum is associated with smoke inhalation, not egophony or stridor. Egophony is a finding in lung consolidation, and stridor is typically seen in upper airway obstruction.

Correct Answer: A

Rationale: The correct answer is A: Presence of nonintact skin. In stage 2 pressure ulcers, the skin is partially lost, forming an open wound with a shallow crater. This distinguishes it from stage 1, where only intact but reddened skin is present. Choices B, C, and D are incorrect because they describe features associated with stages 4, 3, and 1 pressure ulcers, respectively. Sinus tracts and extensive tissue damage characterize stage 4 ulcers, while damage to subcutaneous tissues is seen in stage 3 ulcers. Reddened skin over bony prominences is indicative of stage 1 pressure ulcers.

Correct Answer: A

Rationale: The correct answer is A: Anterior. "Anterior" is used to describe the front of the body. This term is commonly used in anatomical language to indicate a position closer to the front of the body. In contrast, "posterior" (choice D) refers to the back of the body, "lateral" (choice B) refers to the side of the body, and "dorsal" (choice C) refers to the back side of an organism. Therefore, in this context, "anterior" is the most appropriate term to describe a location towards the front of the body.

Correct Answer: C

Rationale: The correct answer is C: Isotonic. Solutions with equal solute concentration have the same osmotic pressure, allowing for balanced movement of water in and out of cells. This prevents cells from shrinking or swelling. Volumetric (A) refers to measurement, hypertonic (B) means higher solute concentration, and metabolic (D) pertains to biochemical reactions, making them all unrelated to the concept of equal solute concentration.

Correct Answer: D

Rationale: The correct answer is D because it encompasses all the key differences between first-degree and second-degree burns. A: A first-degree burn affects only the epidermis, while a second-degree burn affects both the epidermis and the dermis. This is correct as first-degree burns are superficial, affecting only the outer layer of the skin, while second-degree burns penetrate deeper into the dermis. B: A first-degree burn is characterized by redness and pain, while a second-degree burn is characterized by blisters and swelling. This is accurate as first-degree burns typically result in redness and pain, whereas second-degree burns involve blister formation and swelling due to damage to deeper skin layers. C: A first-degree burn heals within a few days, while a second-degree burn may take several weeks to heal. This is true as first-degree burns are minor and usually heal quickly, whereas second-degree burns require more time to heal due to the deeper tissue damage. Therefore, by considering all the distinctions
