IV therapy, or intravenous therapy, involves the administration of fluids, medications, nutrients, or blood products directly into a patient’s vein using a needle or catheter. This method allows for rapid absorption and delivery, bypassing the digestive system.
Key Purposes:
– Hydration: Replenishes fluids and electrolytes in cases of dehydration from illness, surgery, or excessive sweating.
– Medication Delivery: Provides antibiotics, pain relievers, chemotherapy drugs, or other treatments that require quick systemic effects.
– Nutrition: Supplies essential nutrients for patients who cannot eat or absorb food normally, such as in cases of gastrointestinal disorders.
– Blood Transfusions: Replaces blood loss or corrects deficiencies in blood components like red cells or platelets.
Types of IV Therapy:
IV Fluids: Solutions like saline or dextrose to maintain hydration and balance electrolytes.
IV Medications: Infusions of drugs for targeted treatment, often via pumps for controlled dosing.
Parenteral Nutrition: Delivers calories, proteins, vitamins, and minerals for long-term nutritional support.
Blood and Blood Products: Transfusions of whole blood, plasma, or platelets for trauma, surgery, or anemia.
IV therapy is commonly used in hospitals, clinics, and home settings, tailored to individual patient needs under professional guidance.

Part 2: 20 IV therap quiz questions & answers
or
1. Question: What is the primary purpose of IV therapy?
Options:
A. To deliver medications directly into the bloodstream
B. To monitor blood pressure
C. To perform blood draws only
D. To administer oral medications
Answer: A
Explanation: IV therapy allows for rapid absorption and delivery of fluids, medications, and nutrients directly into the vein, bypassing the digestive system for immediate effect.
2. Question: Which type of IV fluid is isotonic and used to expand intravascular volume?
Options:
A. 0.9% Sodium Chloride
B. 5% Dextrose in Water
C. 0.45% Sodium Chloride
D. 3% Sodium Chloride
Answer: A
Explanation: 0.9% Sodium Chloride is isotonic, meaning it has the same osmolarity as blood, making it suitable for fluid resuscitation without causing cell shifts.
3. Question: What is a common complication of IV therapy involving fluid leaking into surrounding tissues?
Options:
A. Infiltration
B. Phlebitis
C. Embolism
D. Hematoma
Answer: A
Explanation: Infiltration occurs when IV fluid escapes from the vein into the surrounding tissue, potentially causing swelling, pain, and tissue damage if not addressed promptly.
4. Question: Which gauge of IV catheter is typically used for rapid fluid resuscitation in emergencies?
Options:
A. 14-16 gauge
B. 18-20 gauge
C. 22-24 gauge
D. 26-28 gauge
Answer: A
Explanation: Larger gauge catheters (14-16) allow for higher flow rates, which is essential for delivering large volumes of fluids quickly during emergencies like trauma or shock.
5. Question: What should be done if a patient experiences pain at the IV site?
Options:
A. Stop the infusion and assess the site
B. Increase the infusion rate
C. Ignore it if the patient is stable
D. Administer more pain medication orally
Answer: A
Explanation: Pain at the IV site may indicate complications like infiltration or phlebitis, so stopping the infusion and assessing the site is critical to prevent further harm.
6. Question: Which IV solution is hypertonic and used for patients with hyponatremia?
Options:
A. 3% Sodium Chloride
B. Lactated Ringer’s
C. 5% Dextrose
D. 0.45% Sodium Chloride
Answer: A
Explanation: 3% Sodium Chloride is hypertonic, drawing fluid into the vascular space to correct low sodium levels, but it must be used cautiously to avoid complications like pulmonary edema.
7. Question: What is the recommended angle for inserting a peripheral IV catheter?
Options:
A. 10-30 degrees
B. 45-60 degrees
C. 90 degrees
D. 0-5 degrees
Answer: A
Explanation: Inserting at a 10-30 degree angle helps ensure the catheter enters the vein without going through the other side, reducing the risk of complications.
8. Question: In IV therapy, what does the acronym “KVO” stand for?
Options:
A. Keep Vein Open
B. Potassium Via Osmosis
C. Key Venous Occlusion
D. Continuous Volume Output
Answer: A
Explanation: KVO refers to a low infusion rate to keep the IV line open and prevent clotting, ensuring the line remains patent for future use.
9. Question: Which patient factor increases the risk of IV therapy complications?
Options:
A. Obesity
B. Young age
C. High blood pressure
D. All of the above
Answer: D
Explanation: Factors like obesity, young age, and high blood pressure can complicate IV access and increase risks such as infiltration or thrombosis due to variations in vein accessibility and condition.
10. Question: What is the first step in preparing for IV insertion?
Options:
A. Explain the procedure to the patient
B. Select the vein
C. Gather supplies
D. Apply a tourniquet
Answer: A
Explanation: Explaining the procedure to the patient first promotes informed consent, reduces anxiety, and ensures patient cooperation during IV insertion.
11. Question: Which type of IV access is used for long-term therapy, such as chemotherapy?
Options:
A. Central venous catheter
B. Peripheral IV
C. Subcutaneous infusion
D. Intraosseous line
Answer: A
Explanation: Central venous catheters provide reliable access for extended periods, allowing for the administration of irritants or large volumes without damaging peripheral veins.
12. Question: What should be monitored during IV antibiotic administration?
Options:
A. Infusion rate and patient vital signs
B. Only the IV site
C. Patient’s diet
D. Room temperature
Answer: A
Explanation: Monitoring the infusion rate and vital signs helps detect adverse reactions, such as anaphylaxis or fluid overload, ensuring safe administration.
13. Question: Which IV fluid is hypotonic and risks causing cell lysis?
Options:
A. 0.45% Sodium Chloride
B. 0.9% Sodium Chloride
C. Lactated Ringer’s
D. 5% Dextrose in 0.9% Sodium Chloride
Answer: A
Explanation: 0.45% Sodium Chloride is hypotonic, which can cause water to shift into cells, potentially leading to hemolysis if not used appropriately.
14. Question: How often should IV sites be rotated to prevent complications?
Options:
A. Every 72-96 hours
B. Daily
C. Weekly
D. Only if complications occur
Answer: A
Explanation: Rotating IV sites every 72-96 hours minimizes the risk of infection, phlebitis, and infiltration by allowing veins time to recover.
15. Question: What is a sign of air embolism during IV therapy?
Options:
A. Sudden shortness of breath
B. Increased urine output
C. Warm skin
D. Bradycardia
Answer: A
Explanation: Air embolism can cause sudden respiratory distress as air bubbles block blood flow, requiring immediate intervention like positioning the patient on their left side.
16. Question: Which medication is commonly administered via IV push for rapid effect?
Options:
A. Furosemide
B. Aspirin
C. Antacids
D. Vitamins
Answer: A
Explanation: Furosemide, a diuretic, is often given via IV push to quickly reduce fluid overload in conditions like heart failure.
17. Question: What is the purpose of flushing an IV line?
Options:
A. To clear the line of blood or medications
B. To increase the infusion rate
C. To add nutrients
D. To test for allergies
Answer: A
Explanation: Flushing maintains patency by preventing clot formation and ensures compatibility when switching between different IV solutions or medications.
18. Question: In pediatric IV therapy, what is a key consideration?
Options:
A. Using smaller gauge catheters
B. Higher infusion rates
C. Adult doses of medication
D. Ignoring vein fragility
Answer: A
Explanation: Pediatric patients require smaller gauge catheters due to their smaller veins, reducing the risk of damage and ensuring safe access.
19. Question: What complication can occur if IV fluids are infused too rapidly?
Options:
A. Fluid overload
B. Hypoglycemia
C. Dehydration
D. Hypokalemia
Answer: A
Explanation: Rapid infusion can lead to fluid overload, causing symptoms like edema, hypertension, and potential heart failure, especially in vulnerable patients.
20. Question: Which practice helps prevent IV-related infections?
Options:
A. Using aseptic technique
B. Reusing needles
C. Infusing without gloves
D. Sharing IV lines between patients
Answer: A
Explanation: Aseptic technique, including proper hand hygiene and sterile equipment, is essential to minimize the introduction of pathogens and reduce infection risk.
