The nurse is preparing to replace a bag of IV fluids for a client receiving fluid therapy. When as-sessing the client, the nurse notes that the IV solution is not dripping. Which of the following should the nurse do to assess the patency of the site?
1. Lower IV container below level of IV site for presence of blood return.
2. Use a large-volume syringe to apply negative pressure to achieve a blood return.
3. Carefully adjust the roller clamp to see an increase in flow rate.
4. Massage the client's arm proximal to where the catheter is inserted.
ANS: 3
The catheter may be lodged against the vein wall; allowing additional pressure from the bag of fluid to flow into the vein may float the catheter into the vein, allowing the instillation of fluids. Using a large-volume syringe could cause the vein to collapse, and massaging the client's arm could dislodge a clot, causing an embolus.
