Limb-threatening extremity injuries:

Correct Answer: B

Rationale: The correct answer is B. Limb-threatening extremity injuries should be definitively managed with a traction splint to stabilize and immobilize the limb, preventing further damage and reducing the risk of complications. This method helps to maintain proper alignment, reduce pain, and minimize the potential for neurovascular compromise. A: Requiring a tourniquet is not always necessary and may lead to complications such as tissue damage. C: Limb-threatening injuries can occur without an open wound, especially in cases of blunt trauma. D: Limb-threatening injuries can include a range of conditions beyond just ischemic or crushed tissue, so this statement is too narrow.

Correct Answer: B

Rationale: The correct answer is B because OBRA was passed in response to reports of abuse and poor care in long-term care facilities. This legislation aimed to improve the quality of care provided to residents in these facilities by setting standards for training, staffing, and resident rights. Choices A, C, and D are incorrect because they do not directly address the main purpose of OBRA, which was to address the issues of abuse and poor care in long-term care facilities.

Correct Answer: B

Rationale: The correct answer is B: Root. The root is the main part of a word that carries its core meaning. It is essential for understanding the basic meaning of the word. Prefixes (A) are added at the beginning of a root to modify its meaning. Suffixes (C) are added at the end of a root to change its grammatical function. Abbreviations (D) are shortened forms of words or phrases and do not inherently provide meaning to a word. Therefore, the root is the main part of a word that gives it meaning, making choice B the correct answer.

Correct Answer: B

Rationale: The correct answer is B: Touch the resident on the arm before identifying herself to let her know the NA is there. This approach is effective because it helps the visually impaired resident to be aware of the nursing assistant's presence before verbal communication. By gently touching the resident's arm, the nursing assistant establishes physical contact and ensures the resident is prepared for interaction. This gesture shows respect for the resident's personal space and helps build trust and rapport. A: Waiting until the resident speaks is not proactive and may lead to confusion or frustration for the visually impaired resident. C: Speaking as little as possible is not helpful as communication is essential for providing care and addressing the resident's needs. D: Using the face of an imaginary clock may be confusing and unnecessary for the resident, as simple and direct communication through touch and verbal cues is more effective.

Correct Answer: A

Rationale: The correct answer is A: Respect the resident's beliefs. This is important in promoting person-centered care and respecting individual autonomy. Nursing assistants should acknowledge and accommodate residents' religious beliefs to provide culturally sensitive care. Trying to change beliefs (B) violates the resident's autonomy. Ignoring dietary restrictions (C) could harm the resident's health. Refusing care (D) goes against the nursing assistant's duty to provide care to all residents.
