A 32-year-old man’s right leg is trapped beneath his overturned car for nearly two hours. Which of the following is most likely to improve chances for limb salvage?

Correct Answer: D

Rationale: Performing lower extremity fasciotomies is the correct choice in this scenario because the prolonged entrapment of the leg can lead to compartment syndrome, a condition where increased pressure within the muscles compromises blood flow, risking limb loss. Fasciotomies involve making incisions to release the pressure and restore circulation, thus improving chances of limb salvage. Applying skeletal traction (A) may help stabilize the leg but won't address the underlying issue of compromised blood flow. Administering anticoagulant drugs (B) is not directly relevant to the treatment of compartment syndrome. Administering thrombolytic therapy (C) is used for dissolving blood clots and is not indicated in this case.

Correct Answer: A

Rationale: The correct answer is A because initial resuscitation in adult patients should start with 1-2L of crystalloid to restore intravascular volume. This helps improve tissue perfusion and oxygen delivery. Monitoring the patient's response (B) is important but not the initial step. Using crystalloid to normalize BP (C) may lead to fluid overload. Permissive hypotension in patients with head injury (D) is contraindicated as it can worsen cerebral perfusion.

Correct Answer: A

Rationale: The correct answer is A: The nurse. Nurses have the education and training to assess residents, monitor progress, administer treatments, and medication. They play a crucial role in coordinating care and ensuring the well-being of residents. Nursing assistants provide hands-on care but do not assess or administer medications. Medical social workers focus on psychosocial needs, not direct medical care. Registered dietitians specialize in nutrition and dietary needs, not direct patient assessment or medication administration.

Correct Answer: C

Rationale: The correct answer is C: Investigating and resolving resident complaints. Ombudsmen are designated to address concerns and complaints from residents in a fair and unbiased manner. They advocate for residents' rights and work to resolve issues within long-term care facilities. Choice A and B are incorrect as they involve tasks typically handled by staff members or managers, not ombudsmen. Choice D is incorrect as organizing outings and activities is not a primary responsibility of an ombudsman, whose focus is on addressing complaints and ensuring quality of care.

Correct Answer: C

Rationale: The correct answer is C because stating Mr. Castillo's blood pressure as 5/6 is an objective fact that can be measured and verified. It is not influenced by personal opinions or interpretations. Option A involves a subjective judgment of his mood, B relies on his verbal report which may not be accurate, and D is a subjective assessment of his relationship with others. Objective information is factual, measurable, and impartial, making C the most suitable choice.
