Final answer:
A very active 2-year-old child pulls out a tunneled central venous catheter. A. Obtain emergency equipment initial nursing action is most appropriate.
Step-by-step explanation:
The most appropriate initial nursing action when a very active 2-year-old child pulls out a tunneled central venous catheter is to obtain emergency equipment. This action prioritizes the preparation for potential complications and ensures that the necessary tools and resources are readily available for immediate intervention.
When a central venous catheter is dislodged, there is an increased risk of bleeding, infection, and other complications. Obtaining emergency equipment allows the nurse to be prepared for any immediate life-threatening situations that may arise, such as severe bleeding. This may include sterile dressings, pressure dressings, and supplies for securing a new catheter if needed.
After obtaining emergency equipment, further assessments and interventions can be initiated. Assessing heart rate, rhythm, and pulses (Option B) is important but may follow the immediate need for equipment. Using cold packs at the exit incision site (Option C) or applying pressure to the vessel insertion site (Option D) are not the primary actions in this situation and could potentially delay necessary interventions.
In summary, obtaining emergency equipment is the most crucial initial nursing action to address the immediate risks associated with a pulled-out tunneled central venous catheter in a very active 2-year-old child.
