A superficial burn is also known as a

Correct Answer: A

Rationale: The correct answer is A: First-degree burn. A superficial burn, also known as a first-degree burn, affects only the outer layer of the skin (epidermis). It is characterized by redness, minor swelling, and pain but does not blister. Second-degree burns (choice C) involve the epidermis and part of the dermis, causing blistering. Third-degree burns (choice B) affect all layers of the skin and may involve underlying tissues, while fourth-degree burns (choice D) extend even deeper, affecting muscles and bones. Therefore, the superficial nature of the burn described in the question aligns with a first-degree burn, making it the correct choice.

Correct Answer: B

Rationale: The correct answer is B: An electric razor. This is the safest option because it reduces the risk of cuts and injuries to residents due to its design and operation. Electric razors have a protective guard that minimizes direct contact with the skin, making them ideal for use by nursing assistants. Choice A, a safety razor, may still pose a risk of cuts if not used properly. Choice C, a disposable razor, lacks the protective guard of an electric razor, increasing the risk of accidental cuts. Choice D, a straight edge razor, is the most dangerous option as it requires skill and precision to use without causing harm to the resident.

Correct Answer: D

Rationale: The correct answer is D: Twice per week. MyPlate recommends consuming seafood as a protein source at least twice a week for optimal health benefits. Seafood is a rich source of omega-3 fatty acids, vitamins, and minerals that support heart health and overall well-being. Eating seafood twice a week helps individuals meet their recommended intake of essential nutrients. Choice A (Once per week) is incorrect because consuming seafood only once a week may not provide enough beneficial nutrients to support optimal health. Choice B (Four times per week) is incorrect as consuming seafood too frequently may lead to excessive intake of certain contaminants like mercury. Choice C (Three times per week) is incorrect as it exceeds the recommended frequency according to MyPlate guidelines.

Correct Answer: B

Rationale: The correct answer is B: Texas catheter. This type of catheter, also known as a condom catheter, is designed to fit over the penis externally rather than being inserted internally like the other types listed. It is commonly used for male patients who have urinary incontinence. The other choices, A: Internal catheter, C: Straight catheter, and D: Indwelling catheter, all refer to catheters that are inserted into the body through the urethra or another access point, which is not the case with a Texas catheter.

Correct Answer: C

Rationale: The correct answer is C because the integumentary system, which includes the skin, hair, and nails, acts as a protective barrier for internal organs from physical injury, pathogens, and harmful UV radiation. The skin's multiple layers provide a tough, waterproof covering that shields organs underneath. Option A is incorrect because waste excretion is primarily carried out by the urinary system. Option B is incorrect as the production of vitamin C occurs in the liver and some other body tissues, not the integumentary system. Option D is incorrect as the integumentary system helps regulate body temperature through processes like sweating and shivering, rather than directly increasing body temperature.
