A client who has developed acute compartment syndrome from a compound fracture of the arm asks the nurse to define what this means. Based on an understanding of the condition, the nurse should explain that:

Bleeding and swelling cause increased pressure under the fascia.

Displaced bones compress nerves and vessels.

Blood supply to the bone is interrupted.

Compression of the muscle tissue restricts blood flow to the area.

Answer and Explanation

The Correct Answer is A

Choice A Reason
Acute compartment syndrome occurs when bleeding or swelling within an enclosed bundle of muscles – known as a muscle compartment – leads to increased pressure. This pressure can impede blood flow to the body tissue and destroy function. The fascia, which is a tough layer of fibrous tissue, does not stretch easily, so any swelling or bleeding can quickly lead to increased pressure.

Choice B Reason
While displaced bones can compress nerves and vessels, this is not the primary mechanism of acute compartment syndrome. Displaced bones are more likely to cause direct injury or impingement, but compartment syndrome specifically refers to the pressure build-up within a muscle compartment that affects circulation and tissue viability.

Choice C Reason
Interruption of blood supply to the bone is a serious concern and can lead to conditions such as avascular necrosis. However, in the context of acute compartment syndrome, the primary issue is the pressure within the muscle compartment rather than direct disruption of blood supply to the bone.

Choice D Reason
Compression of muscle tissue can restrict blood flow to the area, which is a part of the pathophysiology of compartment syndrome. However, the compression is a result of increased pressure within the compartment, not the primary cause. The increased pressure is due to bleeding and swelling, which is why choice A is the most accurate description.

Correct Answer is A

Explanation

Choice A Reason:
Dantrolene is used in the management of malignant hyperthermia, a life-threatening complication characterized by muscle rigidity and elevated temperature, often triggered by certain anesthetics. The patient's symptoms of muscle rigidity and brown urine, which may indicate myoglobinuria, along with elevated temperature and heart rate, are suggestive of this condition. Dantrolene acts by reducing calcium release from the sarcoplasmic reticulum of skeletal muscle, thereby reducing muscle contraction and metabolic demand.

Choice B Reason:
Metoprolol, a beta-blocker, is not the first-line treatment for symptoms suggestive of malignant hyperthermia. While it can reduce heart rate and blood pressure, it does not address the underlying pathophysiology of malignant hyperthermia and is not indicated in this scenario.

Choice C Reason:
Increasing the rate of lactated Ringer's solution is not the primary intervention for malignant hyperthermia. While maintaining hydration is important, it does not directly counteract the pathophysiological processes at play in malignant hyperthermia.

Choice D Reason:
While liver function tests can be important in assessing overall organ function post-operatively, they are not the immediate priority in a suspected case of malignant hyperthermia. The priority is to treat the acute and life-threatening symptoms first.

A. Assess if the client's urine output has increased. B. Ask the client if chest pain is relieved. C. Take the client's blood pressure. D. Ask the client to ambulate and assess for the absence of dyspnea.

Correct Answer is B

Explanation

Choice A Reason
Increased urine output is not a direct indicator of the effectiveness of nitroglycerin for angina pectoris. Nitroglycerin is a vasodilator used primarily to relieve chest pain by improving blood flow to the heart muscle, not to influence urine production.

Choice B Reason
Asking the client if their chest pain has been relieved is the most direct method of evaluating the effectiveness of nitroglycerin. Relief of chest pain indicates that the medication is working as intended, reducing the ischemia that causes angina.

Choice C Reason
While taking the client's blood pressure is important, especially since nitroglycerin can cause hypotension, it is not the primary method for evaluating the effectiveness of the medication in relieving angina. Blood pressure measurements are more of a safety check to monitor for adverse effects.

Choice D Reason
Ambulation and assessing for the absence of dyspnea can be part of an overall evaluation of the client's cardiovascular status, but they are not specific to evaluating the effectiveness of nitroglycerin for angina relief. Dyspnea may be a symptom of heart failure or other conditions, not specifically angina pectoris.
