A 25 year old male is brought to the hospital after sustaining partial and full thickness burns involving 60% of his body surface are His right arm and hand are severely burne There are obvious full thickness burns of the entire right hand and a circumferential burn of the right arm. Pulses are absent at the right wrist and are not detected by doppler examination. The first step in management of the right upper extremity should be:

Correct Answer: C

Rationale: The correct answer is C: "Escharotomy." An escharotomy is a surgical procedure done to release constriction caused by eschar (burned tissue) in order to restore circulation and prevent ischemia. In this case, the patient has circumferential burns on the right arm leading to absent pulses, indicating compromised blood flow. Performing an escharotomy will relieve the pressure, restore blood flow, and prevent further tissue damage and potential limb loss. Choice A: "Fasciotomy" is incorrect as fasciotomy is usually performed in cases of compartment syndrome, which is a different condition from constriction due to burns. Choice B: "Angiography" is incorrect as it is a diagnostic procedure to visualize blood vessels, not a treatment for constriction caused by burns. Choice D: "Heparinization" is incorrect as heparinization is a treatment for blood clotting disorders and not indicated in this scenario of compromised blood flow due to burns.

Correct Answer: A

Rationale: The correct answer is A because sharing personal information about residents violates their right to privacy and confidentiality. Residents have the right to keep their personal information confidential. Choice B is correct as it aligns with the residents' right to voice grievances. Choice C respects the resident's right to be informed. Choice D empowers the resident in making choices, respecting their autonomy.

Correct Answer: C

Rationale: The correct conversion of 7:45 p.m. to military time is 1945 hours. In military time, the hours from 1 p.m. to 11 p.m. are simply expressed by adding 12 to the standard time. Therefore, 7 p.m. + 12 = 19, making it 1900 hours. Then, add the minutes, which remain the same, giving us 1945 hours. Choice A is incorrect as it is missing the "1" in front of the "9". Choice B is incorrect as 975 hours would not be a valid military time format. Choice D is incorrect as it combines the incorrect format of choice A with an incorrect hour value.

Correct Answer: A

Rationale: The correct answer is A: Displacement. Laura is displacing her anger from her supervisor onto the resident. This defense mechanism involves redirecting emotions from the original source to a less threatening target. This is evident as Laura is taking out her frustration on the resident, who is an easier target than her supervisor. Regression (B) involves reverting to earlier developmental stages, denial (C) is refusing to acknowledge reality, and rationalization (D) is justifying behaviors with logical reasoning, none of which apply in this scenario.

Correct Answer: A

Rationale: The correct answer is A because removing the resident from the situation immediately ensures their safety and reporting it to the nurse is essential for proper investigation and intervention by the appropriate authorities. Choice B is incorrect as ignoring the abuse enables further harm. Choice C is incorrect as the family may not be equipped to handle the situation effectively. Choice D is incorrect as confronting the abuser directly can escalate the situation and compromise safety.
