Questions with All Actual Detailed
Answers 2025-2026 Updated.
Purpose of IV therapy - Answer - Maintain/replace/correct fluid and electrolyte
balance/losses/imbalance
- Provide venous access
IV Therapy - Answer - Immediate absorption into bloodstream
- Rapid onset (immediate physiological response)
Peripheral IV (PIV) - Answer - most common IV
- short term therapy
- placement = superficial veins of the hands and forearm
- IV fluids, medications, blood products
Peripheral Venous Catheters (PIVCs) types - Answer Short PIVCs
Long PIVC
Midline catheter
Short PIVCs - Answer 1. Inserted into superficial veins
2. Duration of therapy = <4 days
3. Length of catheter = <3"
4. Tip of catheter terminates in peripheral vein
5. Not appropriate for vesicants, irritants, are parenteral nutrition
Long PIVCs - Answer 1. Inserted in either superficial or deep peripheral veins
2. Can be considered when:
- short PIVC is not long enough to cannulate available vein
- difficulty palpating or visualizing vessels with naked eye
Midline Catheter (MC) - Answer 1. Duration of therapy = 5-14 days
2. Can be inserted thru basilic, cephalic, or brachial veins and terminate at or before axillary lvl
3. Not considered a central line -> no continuous vesicants/extreme pH or osmolarity/parenteral
nutr.
, MC Contraindications - Answer Pt history of:
- Thrombosis
- Hypercoagulability
- Dec venous flow to extremities
- End stage renal disease
Over the needle catheter types - Answer - Magma = 14g
- Gray = 16g
- Green= 18g
- Pink = 20g
- Blue = 22g
- Yellow = 24g
Magma (14g) for - Answer Trauma
Gray (16g) for - Answer Major surgery, large vol infusions, unstable pts
Green (18g) for - Answer Large vol infusions, multiple/rapid transfusion
Pink (20g) for - Answer Meds, hydration, infusions
Blue (22g) for - Answer Small veins, common for SHORT TERM access, usually can't
administer blood products
Yellow (24g) for - Answer Fragile small veins, pediatrics, last resort for adults
Recommended gauge size for infusions - Answer 20-24 gauge
22-26 gauge catheters are recommended for... - Answer Neonates, peds, older adults,
limited venous access
Primary lines - Answer - continuous primary infusion
- bolus of fluid, intermittent
- may have intermittent secondary infusions
