Problem 9 - Clinical Nursing Skills and Techniques

Question

The nurse is involved in resuscitating a patient. The AED has just delivered a shock. What should be done immediately after the shock has been delivered? 1 Continue CPR for another minute until the AED recharges 2 Start an IV line of normal saline with a large-size IV catheter 3 Reposition patient's head for better respiratory effort 4 Continue CPR for 2 minutes

Step-by-Step Solution

Answer

Continue CPR for 2 minutes immediately after the shock.

Step 1: Understanding AED Protocol

An Automated External Defibrillator (AED) is a device used to help those experiencing sudden cardiac arrest. It delivers an electric shock to help the heart re-establish an effective rhythm. Standard protocol after delivering a shock is to continue with CPR immediately.

Step 2: Identifying the Correct CPR Duration

The current guidelines suggest that after a shock is delivered by the AED, chest compressions should be resumed immediately. The CPR should be continued for 2 minutes before the rhythm is reassessed by the AED. This is to ensure that blood circulation is maintained.

Step 3: Evaluating Given Options

The options provided are: 1) Continue CPR for another minute until the AED recharges, 2) Start an IV line, 3) Reposition patient's head, 4) Continue CPR for 2 minutes. Analyzing these options, option 4 aligns with the guideline to perform CPR for 2 minutes immediately after a shock.

Step 4: Verifying Best Practice

The best practice in AED usage confirms that CPR should be immediately resumed after a shock and continued for about 2 minutes before re-assessment.

Key Concepts

AED Protocol

When a person experiences a sudden cardiac arrest, an Automated External Defibrillator (AED) can be crucial in saving their life. An AED is designed to assess the heart's rhythm and, if necessary, deliver an electric shock to restore a normal heartbeat.
The AED comes with voice prompts and visual instructions to guide you through the procedure. Here's an outline of the typical AED protocol:

• Turn on the AED by pressing the power button.
• Attach the electrode pads to the patient's bare chest as shown in the diagrams on the pads.
• Ensure nobody is touching the patient while the AED analyzes the heart rhythm.
• If the AED advises a shock, make sure everyone stands clear and press the shock button.

It is vital to act quickly and follow these steps accurately to increase the chances of resuscitating the patient.

Standard CPR Duration

After a shock is delivered by an AED during a cardiac arrest scenario, immediate action is essential. The standard duration for performing CPR following this intervention is 2 minutes. This time frame is based on current medical guidelines and is designed to optimize blood circulation.
Performing CPR for 2 minutes ensures that oxygen-rich blood continues to circulate throughout the body, reaching vital organs, particularly the brain. It's crucial not to pause for longer than necessary to check for a pulse or breathing. The focus should remain on high-quality chest compressions to maintain circulation until further assessment can be made. This approach helps keep the patient as stable as possible during this critical period.

Cardiac Arrest Management

Managing cardiac arrest requires a quick and coordinated response. Once it is determined that a person is in cardiac arrest, immediate action can significantly improve their chance of survival.
Here are the key steps involved in managing cardiac arrest:

• Recognize the signs, such as an unconscious state and absence of breathing or pulse.
• Call for emergency medical services immediately.
• Start CPR with chest compressions and breaths if trained to do so, or only compressions if you are not.
• Deploy and utilize an AED as soon as it is available.

These actions should be performed as a continuous cycle until professional help arrives. The goal is to restore the heart's function by addressing the stoppage in circulation and preventing deterioration of the patient's condition.

Post-Shock Procedure

After delivering a shock with an AED, there is a critical window where CPR must be resumed without delay. This is referred to as the post-shock procedure and involves performing 2 minutes of CPR.
During these post-shock compressions, keep in mind:

• Focus on maintaining the right depth and speed of compressions: compress to a depth of 2 inches at a rate of 100-120 compressions per minute.
• Ensure minimal interruptions in CPR to maximize the blood flow.
• Continue for the full 2 minutes even if the patient's condition appears to change; reassessment will occur afterwards.

The goal is to prioritize circulation and maximize the chances of successful defibrillation results. Post-shock management is integral to improving outcomes in cardiac arrest cases.
