A post-op client is to receive the following: D5%W/0.45% NS 1 L to infuse over 5 hours. What is the appropriate setting on an infusion pump in milliliters per hour? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Review daily the necessity of the central venous catheter: One of the most effective strategies to reduce the risk of catheter-related bloodstream infections is to remove the central line as soon as it is no longer needed. Daily evaluation of necessity prevents prolonged catheter use, which significantly increases infection risk. Removing the source of potential infection is the ultimate preventative action.

B. Maintain a pressure of 300 mm Hg on the flush bag: While maintaining appropriate flush pressure is important for catheter patency and preventing blood clots, it does not play a direct role in preventing bloodstream infections. This action is more related to ensuring adequate line function rather than infection control.

C. Cleanse the insertion site daily with isopropyl alcohol: Current guidelines recommend using chlorhexidine-based solutions rather than isopropyl alcohol for skin antisepsis due to better antimicrobial efficacy. Daily site care is important, but the choice of antiseptic is critical in reducing infection risk.

D. Change the pressurized tubing system and flush bag daily: Tubing and flush systems should be changed typically every 72–96 hours unless contamination is suspected. Changing them daily is not recommended and does not provide added protection against infection it may even increase risk with unnecessary manipulation.

A. Administer amiodarone IV push followed by a continuous infusion: Amiodarone is part of the Advanced Cardiac Life Support (ACLS) algorithm for ventricular fibrillation (VF) or pulseless ventricular tachycardia, but it should only be given after confirming the rhythm and initiating basic life support steps, including pulse check.

B. Establish unresponsiveness and check the carotid pulse: The rhythm strip shows ventricular fibrillation, a life-threatening arrhythmia. However, before initiating advanced interventions such as defibrillation, the nurse must first confirm the client is unresponsive and pulseless, which is the correct initial action according to ACLS protocols.

C. Immediately defibrillate the client using the synchronous mode: Defibrillation is the correct treatment for VF, but it must be done in unsynchronized mode. Additionally, it is not appropriate to defibrillate until pulselessness is confirmed. Synchronized mode is used for rhythms like unstable SVT or atrial fibrillation not VF.

D. Initiate a rapid response call and increase the monitor’s sensitivity: A rapid response team is called for deteriorating patients who are still responsive. If the client is unresponsive and pulseless, a code blue or cardiac arrest protocol should be initiated, not just a rapid response. Monitor sensitivity adjustments are irrelevant in a confirmed life-threatening rhythm.
