A 34-year-old man is brought to the ED after being pinned to the wall of a building by a cement truck. He is in obvious shock, and has deformities and marked swelling of both thighs. Although no open wounds are present, his shock:

Correct Answer: C

Rationale: Step 1: The scenario describes a man pinned by a cement truck with deformities and swelling in both thighs, indicating significant trauma. Step 2: The absence of open wounds suggests internal bleeding as the cause of shock. Step 3: Bilateral femoral fractures can lead to significant blood loss, resulting in shock. Step 4: Therefore, the shock is consistent with blood loss from bilateral femoral fractures, making choice C the correct answer. Step 5: The other choices are incorrect because shock in this case is more likely due to internal bleeding rather than pelvic fracture (A), fixed percentage blood loss (B), or traction splints (D).

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: Bathing a resident. Nursing assistants typically assist with activities of daily living, such as bathing, grooming, and feeding residents. This task falls under the scope of practice for nursing assistants and helps maintain the hygiene and comfort of residents. Administering medication (choice A) is typically done by licensed nurses. Changing sterile dressings (choice C) is usually performed by nurses or other healthcare professionals with specialized training. Giving tube feedings (choice D) also requires specialized training and is usually done by licensed nurses or dietitians. Therefore, the correct answer is B as it aligns with the typical responsibilities of nursing assistants.

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.
