A superficial burn is also known as a

Correct Answer: A

Rationale: The correct answer is A: First-degree burn. A superficial burn only affects the outer layer of the skin, causing redness and pain without blistering. This matches the characteristics of a first-degree burn. Second-degree burns involve damage to the second layer of skin, resulting in blistering. Third-degree burns extend into deeper tissues, while fourth-degree burns affect muscles and bones. Therefore, A is the correct answer as it accurately describes a superficial burn.

Correct Answer: B

Rationale: The correct answer is B: An electric razor. Electric razors are the safest option as they reduce the risk of cuts, nicks, and skin irritation compared to other types of razors. The design of electric razors minimizes the chances of accidental injuries, making them ideal for use by nursing assistants on residents. Safety razors (choice A) can still cause cuts if not used properly. Disposable razors (choice C) can be sharp and pose a risk of accidental cuts. Straight edge razors (choice D) are very sharp and require skill to use safely, making them unsuitable for use by nursing assistants in a healthcare setting.

Correct Answer: D

Rationale: According to MyPlate, individuals are encouraged to consume seafood at least twice a week as a protein source. This recommendation is based on the health benefits of seafood, such as being a good source of omega-3 fatty acids. Consuming seafood twice a week can help lower the risk of heart disease and provide essential nutrients. Therefore, option D is the correct answer. Option A (Once per week) is incorrect as it does not meet the recommended frequency for seafood consumption according to MyPlate. Option B (Four times per week) and option C (Three times per week) are also incorrect as they exceed the recommended intake and may not provide a balanced diet with other protein sources.

Correct Answer: B

Rationale: The correct answer is B: Texas catheter. This type of catheter is also known as an external catheter, as it fits over the penis rather than being inserted internally. This type of catheter is commonly used for male patients who have difficulty controlling their bladder. The other choices are incorrect because: A: Internal catheter is inserted into the bladder through the urethra. C: Straight catheter is a type of intermittent catheter used for short-term bladder drainage. D: Indwelling catheter is inserted into the bladder and remains in place for continuous drainage.

Correct Answer: C

Rationale: The correct answer is C: Protect internal organs from injury. The integumentary system consists of the skin, hair, nails, and glands that protect the body from external factors like pathogens, UV rays, and physical injuries. The skin acts as a barrier, preventing harmful substances from entering the body and also helps regulate body temperature. Choices A, B, and D are incorrect because excreting waste through urine is the function of the urinary system, the production of vitamin C is primarily done by the liver and kidneys, and increasing body temperature is regulated by the thermoregulatory system, not the integumentary system.
