PIV

(peripheral intravenous catheter) catheter inserted into the peripheral veins for delivery of short-term infusion therapies

4 techniques for the older pt with fragile veins (3)

2

The nurse is preparing a continuous intravenous (IV) infusion at the medication cart. As the nurse goes to insert the spike end of the IV tubing into the IV bag, the tubing drops and the spike end hits the top of the medication cart. The nurse should take which action? 1. Obtain a new IV bag. 2. Obtain new IV tubing. 3. Wipe the spike end of the tubing with Betadine. 4. Scrub the spike end of the tubing with an alcohol swab.

2. Obtain new IV tubing. NCLEX

The nurse has a prescription to hang a 1000-mL intravenous (IV) bag of 5% dextrose in water with 20 mEq of potassium chloride. The nurse also needs to hang an IV infusion of piperacillin/tazobactam. The client has one IV site. The nurse should plan to take which action first? 1. start a second IV site 2. check compatibility of the medication and IV fluids 3. mix the prepackaged piperacillin/tazobactam per agency policy 4. prime the tubing with the IV solution and back-prime the medication

2. check compatibility of the medication and IV fluids -if fluids and medications are compatible, the nurse should hang them together -if fluids and medications aren't compatible, it would be appropriate to start a second IV site NCLEX

For most adults, the catheter gauge for infusing fluids and medication is:

20- to 22-gauge (20-gauge is most common according to PowerPoint)

Which gauge would you use for pediatric pts and older adult pts?

22- 24-gauge

Which gauge would you use for neonates?

24- 26-gauge

The nurse plans to administer a medication by intravenous (IV) bolus through the primary IV line. The nurse notes that the medication is incompatible with the primary IV solution. Which is the appropriate nursing action to safely administer the medication? 1. Start a new IV line for the medication. 2. Flush the tubing after the medication with sterile water. 3. Flush the tubing before and after the medication with normal saline. 4. Call the health care provider for a prescription to change the route of the medication.

3. Flush the tubing before and after the medication with normal saline. NCLEX

The nurse is preparing to infuse (piggyback) a 50-mL dose of a compatible medication through the primary intravenous (IV) line. How should the nurse correctly attach the medication bag? 1. Hanging the medication bag level with the primary IV bag 2. Hanging the medication bag lower than the primary IV bag 3. Hanging the medication bag higher than the primary IV bag 4. Disconnecting the primary IV solution and plugging in the medication

3. Hanging the medication bag higher than the primary IV bag (For an intermittent IV infusion that is piggybacked to the primary IV line, the bag for the intermittent infusion is placed higher than the primary solution bag. This allows gravity to assist in infusing the medication.) NCLEX

Place the discontinuing a peripheral IV steps in order: 1. Remove IV site dressing and any stabilization devices 2. Inspect catheter and for intactness after removal 3. Place sterile gauze over venipuncture site 4. Check HCP orders 5. Keep gauze in place and continue to apply pressure for 2-3 minutes 6. Explain to patient 7. Keep catheter hub parallel to skin during withdrawal 8. Apply light pressure while withdrawing catheter away from insertion site 9. Perform hand hygiene and don clean gloves
