ATI: Skills Module - IV Therapy

Which of the following is an important nursing action when converting an IV infusion to a saline lock?
A. Open the roller clamp of the primary infusion to prime the saline lock
B. Apply pressure with a syringe to clear resistance in the IV catheter
C. Att

D. Flush the IV catheter to confirm patency
Rationale: It is essential to attach the pried saline lock adapter to the extension tubing and to flush the tubing with normal saline to confirm patency. B could cause embolism.

A nurse is discontinuing an IV infusion. For which of the following reasons is it important to verify and document the integrity and condition of the IV catheter?
A. A broken-off catheter tip indicates the risk for an embolus
B. Catheter erosion indicates

A. A broken-off catheter tip indicates the risk for an embolus
Rationale: The tip of the catheter can break off, thus creating an embolus. To limit the movement of the embolus, the nurse should apply a tourniquet high on the extremity where the IV line wa

A nurse initiating a peripheral IV infusion punctures the skin and selected vein and observes blood return in the flashback chamber of the IV catheter. Which of the following actions should the nurse preform next?
A. Secure the catheter to the skin with a

B. Lower the catheter until it is almost flush with the skin
Rationale: Lowering the angle and then advancing the catheter slightly facilitates full penetration of the wall of the vein, thus placing the catheter within the vein's lumen and making it easy

A nurse has just inserted a peripheral IV catheter for a continuous infusion. To secure the catheter, the nurse should
A. leave the connection between the hub and the tubing uncovered
B. wrap tape around the circumference of the patient's arm
C. tape the

A. leave the connection between the hub and the tubing uncovered
Rationale: This makes it possible to replace the tubing without removing the dressing.

A nurse finds a patient's IV insertion site red, warm, and slightly edematous. Which of the following actions should the nurse perform first?
A. Check for a blood return
B. Elevate the extremity
C. Discontinue the IV line
D. Apply warm, moist heat

C. Discontinue the IV line
Rationale: The patient has classic signs of phlebitis, an inflammation of the vein. The IV line must be discontinued immediately to reduce the risk of thrombophlebitis and embolism.

A nurse is removing an IV catheter from a patient whose IV infusion has been discontinued. Which of the following actions is appropriate?
A. Apply firm pressure over the vein
B. Leave the roller clamp slightly open
C. Pull the catheter straight back form

C. Pull the catheter straight back form the insertion site
Rationale: With the catheter stabilized and using a slow, steady movement, the nurse should withdraw the catheter straight back and away form the insertion site, making sure to keep the hub parall

A patient in early stage renal failure is prescribed an infusion of 0.45% NaCl. This type of solution is appropriate because it
A. pulls fluid from the cells and increases vascular volume
B. dilutes extracellular fluid and rehydrates the cells
C. replaces

B. dilutes extracellular fluid and rehydrates the cells
Rationale: Infusing a hypotonic solution such as 0.454% sodium chloride moves fluid into the cells, thus enlarging and rehydrating them. A is hypertonic, C is isotonic, D is hypertonic

A nurse has just initiated a peripheral IV infusion of 5% dextrose in water. How often should the nurse plan to replace the primary infusion tubing?
A. Every 24 hours
B. Every 48 hours
C. Every 72 hours
D. Every 96 hours

D. Every 96 hours
Rationale: Unless the infusion system has been compromised in some way, changing the administration set 72 hours after initiating the IV would be inappropriate.
CDC recommends changing the IV tubing no more than every 92 hours unless the

A nurse who has just initiated an IV infusion explains to the patient that complications are possible and that she will monitor the infusion regularly. The nurse should teach the patient that which of the following findings is an indication of early infil

D. Coolness
Rationale: Coolness is a classic sign of infiltration, along with swelling, pallor, and possibly tenderness. Infiltration is a leakage of IV solution out of the intravascular compartment into the surrounding tissue.

A patient is to receive 1,000 mL of 5% dextrose in lactated Ringer's over 8 hours. Using tubing with a drop factor of 15 gtt/mL, the nurse should regulate the fluid to infuse at how many drops per minute?

31 gtt/min
