Nurs 320 Midterm || IV Therapy Final
Exam Questions Fully Solved Graded
A+.
what assessments should the nurse complete prior to initiating IV therapy? - Answer - perform
renal and cardiac assessment
- monitor patient status (weight, I/Os, labs)
- vitals
what lab value are important when monitoring IV fluids? - Answer sodium and potassium
**list several factors that might influence the flow rate via gravity (off pump) of an IV solution -
Answer 1. height of solution
2. patency of cannula
3. venous spasms
4. size of cannula
5. blood in tubing
6. present of local complications
Factors Influencing Gravity Flow Rate: height of solution - Answer higher the solution the
faster the rate
Factors Influencing Gravity Flow Rate: patentcy of cannula - Answer can be blocked by blood
or clots
Factors Influencing Gravity Flow Rate: venous spasms - Answer cold IV fluid dec rate
Factors Influencing Gravity Flow Rate: size of cannula - Answer low gauge size = faster rate
**list several types of central catheters (6) - Answer 1. peripherally inserted central catheters
(PICC)
2. multi-lumen catheter
, peripherally inserted central catheters - Answer - placed in antecubital fossa
- tip resides in SVC
- no BP/blood draws in this extremity
PICC advantages - Answer low complication rates, less money, ability to be inserted at bedside
multi lumen catheter - Answer can deliver 2 or more solution at same time via separate
pathways
tunneled central catheter location - Answer tunneling of catheter through subcutaneous
tissue
tunneled central catheter advantages - Answer used for long term needs
non-tunneled catheters location - Answer placed in subclavian or internal jugular vein
non-tunneled catheter advantages - Answer short term use
implanted ports location - Answer no part of catheter is visible
- tip subsides in SVC
- venous system
what are implanted ports commonly used for? - Answer chemotherapy
Intraosseous route location - Answer IO route into bone marrow of proximal humerus,
proximal and distal tibia
Intraosseous route advantages - Answer high infusion rates
good for severely dehydrated
cardiac/respiratory emergencies
