The safest type of razor for a nursing assistant to use on residents is

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: 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.

Correct Answer: C

Rationale: The correct answer is C: Under the tongue. Nitroglycerin pills are typically taken sublingually, or under the tongue, where they can be rapidly absorbed into the bloodstream to provide quick relief for angina symptoms. This route allows the medication to bypass the digestive system and liver metabolism, leading to faster onset of action. Explanation of other choices: A: Injections - Nitroglycerin is not typically administered as injections for angina relief. B: Intravenously - Intravenous administration is not a common route for nitroglycerin used in the treatment of angina. D: Rectally - Nitroglycerin is not typically given rectally for the treatment of angina.

Correct Answer: B

Rationale: The correct answer is B: Adduction. Adduction refers to the movement of a body part towards the midline of the body. This is the correct term for moving a body part towards the body. In contrast, A: Addition is not a term used in anatomy for this type of movement. C: Agitation is unrelated to the movement of body parts. D: Abduction is the opposite movement, where a body part moves away from the midline of the body. Therefore, B is the correct answer as it specifically describes the action of moving a body part towards the body's midline.
