Question 1 pts
Which of the following are advantages of volume-controlled intravenous (IV) infusions? (Select all that apply.)
There is less risk of rapid-dose infusion (as compared with IV push) because medications are diluted and infused over longer time intervals
(e.g., 30 to 60 minutes).
It allows for administration of medications (e.g., antibiotics) that are stable for a limited time in solution.
The risk of side effects is minimal because this is the safest method of administering IV medications.
It is the preferred method in an emergency.
Using volume-controlled infusions has several advantages: It reduces the risk of rapid-dose infusion by IV push.
Medications are diluted and infused over longer time intervals (e.g., 30 to 60 minutes). It allows for administration of
medications (e.g., antibiotics) that are stable for a limited time in solution. It allows for control of IV fluid intake. The risk of
side effects still remains; the safest method of administering IV medications is by large-volume infusions. IV bolus is the
preferred method in an emergency when quick-acting medications are needed.
Question 2 pts
The nurse is administering vancomycin (Vancocin) 500 mg by IV piggyback over 60 minutes. An hour later the nurse returns to find
that approximately half of the infusion has been administered and the IV site appears swollen, pale, and is cool to the touch. What
is the appropriate action to be taken for this unexpected outcome? (Select all that apply.)
Stop the infusion.
Recheck the patient for an allergy to vancomycin.
Provide extravasation care.
Increase the flow rate.

These are signs of infiltration. The infusion will have to be stopped and the IV access device discontinued. Some IV
medications are extremely harmful to subcutaneous tissue. The nurse should provide IV extravasation care (e.g., injecting
phentolamine around the IV infiltration site) as indicated by agency policy, use a medication reference, or consult a
pharmacist to determine appropriate follow-up care. If continuation of therapy is indicated, a new IV site, preferably in the
other extremity, will have to be started. Increasing the rate of flow would only make the infiltration worsen. Providing the
patient with a blanket may provide comfort but will fail to resolve the problem. These symptoms are not indications of an
allergic response.
Question 3 pts
Which of the following is a correct sequence for administering an IV piggyback through a saline lock?
Cleanse the port with alcohol and assess the patency of the IV line by flushing it with 2 to 3 mL of sterile normal saline. Attach IV piggyback
tubing to the saline lock, and administer the medication per order. When the infusion is completed, disconnect the tubing, cleanse the port
with alcohol, and flush the IV line with 2 to 3 mL sterile normal saline.

Cleanse the port with alcohol and assess the patency of the IV line by flushing it with 2 to 3 mL of sterile normal saline. Attach IV piggyback
tubing to the saline lock, and administer the medication per order. When the infusion is completed, disconnect the tubing and document.
The nurse should flush the port with normal saline prior to administering the IV piggyback to verify patency and flush any
blood from the access device. After the piggyback solution has infused, the nurse should again flush the access device with
normal saline to clear the port of any medication and maintain patency of the saline lock. In the other sequences critical
steps were missed. The nurse failed to assess for patency by aspirating for blood return or flushing the access device in
one and in the other the nurse failed to flush the access device after the IV piggyback had infused. This may result in
medication being left in the access device and clotting of the catheter.
Question 4 pts
Order: Oxacillin (Bactocil) 400 mg, IV, q6h.
Medication available: 400 mg oxacillin (Bactocil) in 100 mL of D5W.
Instruction: Infuse over 40 minutes. Micro-drip tubing (60 gtts/mL) is being used.
The infusion pump should be set to mL per hour.
