The nurse is caring for a client on a telemetry unit. The client's cardiac monitor exhibits the rhythm below. How should the nurse document this rhythm?
Sinus rhythm with first-degree heart block
ST-segment elevation myocardial infarction (STEMI)
Atrial fibrillation
Ventricular tachycardia
The Correct Answer is B
A. Sinus rhythm with first-degree heart block: This rhythm is characterized by a regular sinus rhythm with a prolonged PR interval (greater than 0.20 seconds), indicating a first-degree heart block.
B. ST-segment elevation myocardial infarction (STEMI): STEMI is indicated by significant ST-segment elevation in specific leads, showing acute myocardial infarction.
C. Atrial fibrillation: Atrial fibrillation shows an irregularly irregular rhythm without distinct P waves.
D. Ventricular tachycardia: Ventricular tachycardia is a rapid heart rhythm originating from the ventricles, with wide QRS complexes and no preceding P waves.

Correct Answer is ["A","C","D"]
Explanation
A. Pharmacological toxins can contribute to myocarditis, as certain drugs may induce inflammatory responses in the myocardium.
B. Pleural infusion is incorrect. Pleural infusion, or pleural effusion, is not directly associated with myocarditis.
C. Autoimmune disorders such as lupus and rheumatoid arthritis can predispose individuals to myocarditis due to immune system dysregulation.
D. Viral infections are a major cause of myocarditis, particularly infections like coxsackievirus, parvovirus B19, and HIV.
E. Peripheral vascular disease is incorrect. While peripheral vascular disease is related to poor circulation, it does not directly contribute to the development of myocarditis.
Correct Answer is B
Explanation
A. Pelvic fracture: Pelvic fractures may cause significant pain and instability but do not typically result in a shortened, adducted, and externally rotated leg.
B. Femoral neck fracture: These findings (shortened, adducted, externally rotated leg) are classic for a femoral neck fracture due to muscle contraction and displacement of the bone.
C. Tibia fracture: Tibia fractures typically present with swelling and deformity, not shortening or rotation of the leg.
D. Fibula fracture: A fibula fracture alone rarely causes leg shortening or rotation as it is a non-weight-bearing bone.
