IV Therapy Quiz
Questions: 16 · 10 minutes
1. A 1,000 mL infusion is scheduled to run evenly over 10 hours. After 4 hours, 700 mL remains. How does the actual infusion compare with the schedule?
It is 100 mL behind
It is 100 mL ahead
It is exactly on schedule
It is 300 mL behind
2. An infusion pump reports air in the line, and air is visibly present in the tubing before it reaches the patient. What is the safest immediate response?
Increase the rate so the air passes through quickly
Silence the alarm and continue while observing the patient
Stop or clamp the infusion and follow the approved air-removal procedure
Flush the tubing into the patient with a syringe
3. A clinician orders controlled hypertonic-fluid therapy for a patient with severe symptomatic hyponatremia. Which ordered solution fits that classification?
D5W
0.45% sodium chloride
3% sodium chloride
Lactated Ringer's solution
4. A patient reports burning and pain during a vesicant infusion, and swelling appears around the catheter. What is the appropriate initial response?
Flush the medication through rapidly with saline
Remove the catheter immediately before attempting any aspiration
Stop the infusion and initially leave the catheter in place for aspiration or antidote steps under protocol
Reduce the rate and reassess after the dose is complete
5. An adult has extracellular-volume depletion after substantial vomiting and diarrhea, with no identified contraindication to routine fluid replacement. Which fluid category most directly supports initial volume expansion?
An isotonic crystalloid
A hypotonic crystalloid
A concentrated hypertonic saline solution
A dextrose solution that primarily supplies free water after metabolism
6. A patient with reduced cardiac or kidney reserve develops shortness of breath and new lung crackles during a rapid IV infusion. Which complication is the main concern?
Local infiltration
Local extravasation
Mechanical phlebitis
Fluid overload
7. An IV site becomes cool, pale, and swollen, and the infusion slows. The fluid is non-vesicant. Which complication best matches these findings?
Phlebitis
Infiltration
Systemic fluid overload
Catheter-related bloodstream infection
8. A peripheral IV site is warm, red, and tender, with discomfort following the path of the vein. What is the most likely local complication?
Infiltration
Fluid overload
Phlebitis
Air embolism
9. Why should a peripheral IV site be assessed regularly while an infusion is running?
To determine the fluid's tonicity from its appearance
To identify infiltration, phlebitis, or extravasation as early as possible
To replace the need for monitoring the patient's overall condition
To prove that the catheter tip remains in a central vein
10. After the dextrose in D5W is metabolized, how does the remaining fluid generally behave in the body?
As a sustained isotonic extracellular-volume expander
As a colloid that remains mainly in the bloodstream
As a hypertonic fluid that draws water out of cells
As free water with a physiologically hypotonic effect
11. A patient with an acute neurological injury has significant cerebral swelling. Why might a hypotonic IV solution be inappropriate?
It contains enough protein to sharply increase plasma oncotic pressure
It can promote water movement into cells and potentially worsen swelling
It remains confined to the vascular space and cannot distribute to tissues
It expands plasma volume more strongly than a concentrated colloid
12. Which crystalloid is ordinarily used to prime compatible blood-administration tubing, subject to the blood bank's protocol?
0.9% sodium chloride
D5W
Lactated Ringer's solution
0.45% sodium chloride
13. An order calls for 1,000 mL to infuse evenly over 8 hours using an infusion pump. What rate should be programmed?
80 mL/hour
125 mL/hour
100 mL/hour
133 mL/hour
14. A 500 mL bag must infuse over 4 hours through tubing calibrated at 15 drops per mL. Rounded to the nearest whole drop, what gravity rate is required?
21 drops/minute
125 drops/minute
42 drops/minute
31 drops/minute
15. Which fluid contains sodium, chloride, potassium, calcium, and lactate?
Lactated Ringer's solution
0.9% sodium chloride
0.45% sodium chloride
D5W
16. Which IV solution is classified as an isotonic crystalloid?
Sterile water for injection
0.45% sodium chloride
3% sodium chloride
0.9% sodium chloride
