A nurse is preparing to administer erythromycin 2 g PO daily in equally divided doses every 6 hr. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A.While medication verification is important, this is not specific to administering an intermittent IV bolus. It is standard practice for high-alert medications, not routine antibiotics.

B. Flushing the IV site with sterile water prior to connecting the secondary infusion is not standard practice. Normal saline is typically used to maintain patency, but it is not necessary before connecting the secondary infusion.
C.To administer a secondary infusion (e.g., antibiotic), the secondary bag must be hung higher than the primary infusion. This allows gravity to prioritize the secondary infusion through the Y-site.

D. Disconnecting the primary IV infusion to connect the secondary infusion is not correct. The secondary infusion should connect to the primary line without disrupting the ongoing infusion unless otherwise indicated.

A. Verapamil: Verapamil is a calcium channel blocker primarily used to treat supraventricular

tachycardias, not ventricular dysrhythmias. It is not typically used for life-threatening ventricular dysrhythmias.
B. Digoxin: Digoxin is a cardiac glycoside used primarily for atrial fibrillation and heart failure, not ventricular dysrhythmias. It is not typically used for life-threatening ventricular
dysrhythmias.

C. Dopamine: Dopamine is a sympathomimetic medication used for hemodynamic support in hypotension and shock. While it may be used in some cases of unstable bradycardia, it is not the first-line medication for life-threatening ventricular dysrhythmias.
D. Amiodarone: Amiodarone is an antiarrhythmic medication used for the treatment of various ventricular and supraventricular dysrhythmias, including life-threatening ventricular
dysrhythmias such as ventricular tachycardia and ventricular fibrillation. It is often used as a first-line medication for these conditions due to its efficacy and safety profile. Therefore, the nurse should anticipate administering amiodarone for the client's life-threatening ventricular dysrhythmia.
