What is the purpose of an escharotomy?

Correct Answer: A

Rationale: An escharotomy is performed to relieve pressure and improve circulation in areas affected by deep burns. This procedure helps prevent complications such as compartment syndrome by releasing the constricting eschar. Choice B is incorrect because while pain relief may be a secondary outcome of the procedure, the primary purpose is to address pressure and circulation issues. Choice C is incorrect as an escharotomy specifically focuses on releasing pressure, not removing necrotic tissue. Choice D is incorrect as the primary goal of an escharotomy is not to prevent infection but rather to address the immediate issues related to deep burn injuries.

Correct Answer: A

Rationale: The correct action to take when a patient reports cramping during enema administration is to lower the height of the solution container. Lowering the height reduces the pressure and speed of the solution entering the rectum, alleviating cramping. Increasing the flow of the enema solution (Choice B) can worsen the discomfort. Stopping the procedure and removing the tubing (Choice C) is not necessary unless there are severe complications. Continuing the enema at a slower rate (Choice D) may not effectively address the immediate cramping issue and could still cause discomfort to the patient.

Correct Answer: A

Rationale: Administering sublingual nitroglycerin is the priority nursing action for a patient with chest pain and possible acute coronary syndrome. Nitroglycerin helps dilate the blood vessels, improve blood flow to the heart, and reduce cardiac workload. This action aims to relieve chest pain promptly and prevent further cardiac tissue damage. Increasing fluids is not the initial priority for a patient with chest pain and possible acute coronary syndrome. Obtaining cardiac enzymes is important for diagnosis but is not the first action in managing acute symptoms. Getting IV access and auscultating heart sounds are important interventions, but they come after administering sublingual nitroglycerin in the management of acute coronary syndrome.

Correct Answer: A

Rationale: The priority action when a patient experiences hypoglycemia after an insulin dose is to check the patient's blood glucose level. This is crucial to confirm hypoglycemia before initiating any treatment. While administering IV dextrose may be necessary if the patient's blood glucose level is critically low, confirming hypoglycemia is essential to guide appropriate interventions. Documenting the incident is important for documentation purposes but is not the immediate priority when the patient's safety is at risk. Continuing to monitor the patient is essential, but it should follow the confirmation and initial management of hypoglycemia.

Correct Answer: A

Rationale: The correct answer is A: 'Gradual loss of function on one side of the body.' In a thrombotic stroke, a clot blocks a cerebral artery, leading to a gradual onset of symptoms such as weakness, numbness, or paralysis on one side of the body. Choice B, 'Sudden loss of consciousness,' is more characteristic of a hemorrhagic stroke. Choice C, 'Severe headache and confusion,' are often associated with subarachnoid hemorrhage rather than thrombotic stroke. Choice D, 'Loss of sensation in the affected limb,' is not a typical symptom pattern for a thrombotic stroke, which usually presents with motor deficits.
