A client is ordered to receive amiodarone 0.5 mg/min. The supply on hand is 1 g/500 mL of NS. Calculate the flow rate of the intravenous medication _________mL/hr. Round answer to the nearest whole number. Enter numeric answer only.

A. Prepare for transcutaneous pacing: The client is symptomatic with sinus bradycardia, hypotension, syncope, and weakness, indicating hemodynamic instability. Transcutaneous pacing provides temporary electrical stimulation to increase heart rate and maintain adequate perfusion until definitive treatment can be initiated.

B. Administer an antiarrhythmic medication: Antiarrhythmic drugs are used to treat tachyarrhythmias, not symptomatic bradycardia. Administering such medications could worsen the bradycardia and further compromise cardiac output.

C. Prepare for synchronized cardioversion: Synchronized cardioversion is indicated for unstable tachyarrhythmias, such as atrial fibrillation or ventricular tachycardia with a pulse. It is not appropriate for bradycardia and could be harmful.

D. Administer a thrombolytic medication: Thrombolytic therapy is used for acute myocardial infarction or thromboembolic events, not for bradycardia. There is no evidence of an occlusive clot causing the current hemodynamic instability.

A. Skin petechiae: Small, pinpoint red or purple lesions on the skin, known as petechiae, are caused by embolic phenomena from vegetations on the heart valves. They are a classic peripheral manifestation of infective endocarditis and support the diagnosis.

B. Friction rub heart sounds: A friction rub is associated with pericarditis, not endocarditis. It occurs when the pericardial layers rub against each other and is not a typical finding in infective endocarditis.

C. Hypothermia: Infective endocarditis generally presents with fever due to systemic infection. Hypothermia is uncommon and would suggest another underlying condition rather than supporting endocarditis.

D. Fever: Fever is the most common systemic manifestation of infective endocarditis. It results from the body’s inflammatory response to bacterial infection of the endocardial surfaces. Persistent or intermittent fevers are characteristic of this condition.

E. New onset murmur: The development of a new heart murmur indicates valve damage or regurgitation caused by vegetations on the heart valves. This is a cardinal cardiovascular sign of infective endocarditis.

F. Splinter hemorrhages on fingernails: Linear, reddish-brown lesions under the fingernails are caused by small emboli from valvular vegetations. Splinter hemorrhages are a classic peripheral sign supporting the diagnosis of infective endocarditis.
