NURS 320 MIDTERM II IV THERAPY
QUESTIONS AND CORRECT ANSWERS
(GRADED A+) | NEW 2025
**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
3. tunneled central catheters
4. non-tunneled central catheters
5. implanted ports
6. intraosseous route
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
