The client arrives to the emergency department with syncope. After placing the telemetry monitor on the client, the nurse sees this rhythm. How should the nurse interpret this rhythm?

Complete (third-degree) heart block

Pacemaker rhythm

Sinus bradycardia

First-degree heart block

Answer and Explanation

The Correct Answer is B

A. Complete (third-degree) heart block: This rhythm is characterized by a lack of relationship between P waves and QRS complexes, indicating a complete dissociation between atrial and ventricular activity.

B. A pacemaker rhythm on an ECG is characterized by the presence of pacing spikes followed by P waves or QRS complexes, depending on whether the pacemaker is pacing the atrium or the ventricle. If the pacemaker is pacing the ventricle, the pacing spike will be followed by a QRS complex. The QRS complexes in a paced rhythm are often wider than normal.

C. Sinus bradycardia: Sinus bradycardia is a slow but regular rhythm originating from the sinus node, with normal P waves and QRS complexes.

D. First-degree heart block: First-degree heart block is characterized by a prolonged PR interval (greater than 0.20 seconds) but with all P waves followed by QRS complexes, differing from third-degree heart block.

Correct Answer is ["A","B","C","E"]

Explanation

A. Compartment syndrome: This is a serious complication that can occur with fractures, including femur fractures. It occurs when increased pressure in the muscle compartment impairs circulation and nerve function.

B. Hemorrhage: Fractures, particularly of long bones like the femur, can result in significant bleeding. Monitoring for hemorrhage is important.

C. Deep vein thrombosis (DVT): DVT is a common complication in clients with fractures and immobilization. The client is at risk for blood clots forming in the legs due to limited movement and prolonged bed rest.

D. Complex regional pain syndrome: While this can occur after fractures, it is less common and typically develops weeks to months after the injury.

E. Fat embolism: A fat embolism is a potential complication of long bone fractures, especially the femur. Fat globules can enter the bloodstream and cause respiratory distress, neurological impairment, and petechial rash.

A. "It is an amino acid which reflects damage to the endothelial lining of arteries. B. "It is a substance composed of free fatty acids reflective of atherosclerosis C. "It is a reliable indicator of the presence of heart failure." D. “It is a protein produced by the liver in response to systemic inflammation."

Correct Answer is C

Explanation

A. "It is an amino acid which reflects damage to the endothelial lining of arteries." BNP is not related to endothelial damage.

B. "It is a substance composed of free fatty acids reflective of atherosclerosis." BNP is not composed of free fatty acids, and it does not reflect atherosclerosis.

C. "It is a reliable indicator of the presence of heart failure." BNP is a hormone released by the heart in response to increased pressure and volume. Elevated levels of BNP are commonly used as a diagnostic marker for heart failure, especially during exacerbations or decompensation.

D. "It is a protein produced by the liver in response to systemic inflammation." BNP is produced by the heart, not the liver.
