Self-Assessment Questions

Chapter 14: Infusion Therapy


1. What is the purpose of an infusion filter in an intravenous administration set? To:

A. eliminate the risk for blood-borne infection through transfusion products.
B. maintain the intravenous flow at a constant set rate.
C. remove particulate matter from the infusion fluid.
D. prevent backflow of infusion fluid.

2. What is the major advantage of a needleless infusion system?

A. The client does not have to undergo the pain of a needlestick.
B. Health care workers have less exposure to contaminated needles.
C. IV flow rates are faster because the tubing has a larger bore than a needle.
D. The cost of intravenous medication administration is reduced because plastic is less expensive to manufacture than metal.

3. Which infusion regulation device should you select for the client needing the most accurate delivery of intravenous fluids?

A. Volumetric pump
B. Nonvolumetric pump
C. Volumetric controller
D. Nonvolumetric controller

4. The client is right-handed and has had a mastectomy of the left breast with a left axillary node dissection one year ago. Which site should you select to start an IV on this client for administration of an irritant medication for the next 48 hours?

A. Right hand
B. Right dorsal forearm
C. Left dorsal forearm
D. Either foot

5. Which technique alteration should you make when initiating a venous access device in an older adult with tissue-paper–thin skin?

A. Use a circumferential restraint, rather than tape, to hold the IV catheter in place.
B. Start the IV in the upper arm or the foot where the skin is thicker.
C. Decrease the angle for needle/catheter insertion.
D. Avoid using dry gauze pads on the IV site.

6. Which statement accurately describes the differences between tunneled and nontunneled central venous access devices (VADs)?

A. Tunneled VADs have a higher risk for extravasation and infiltration than do nontunneled VADs.
B. Nontunneled VADs of all types are routinely inserted by registered nurses, and tunneled VADs must be placed by a surgeon.
C. Tunneled VADs can have multiple lumens and ports, whereas nontunneled VADs have only a single lumen and one access port.
D. Nontunneled VADs are inserted through the skin directly into a blood vessel and tunneled VADs extend through the tissues for some distance before entering a blood vessel

7. In what way does a peripherally inserted central catheter (PICC) differ from other types of central lines?

A. PICC lines may be used for either arterial or venous access.
B. PICC lines are initially inserted into a peripheral vein and then threaded into a central vein.
C. Central line tips rest in the subclavian or superior vena cava vessels and PICC line tips do not rest that far centrally.
D. Central lines can be used for any type of intravenous therapy and PICC lines are limited to antibiotic therapy and transfusion therapy.

8. Which problem or complication is most commonly associated with peripheral IV therapy rather than central IV therapy?

A. Air embolism
B. Nerve injury
C. Pneumothorax
D. Thrombophlebitis

9. What is the most common use for intra-arterial infusion therapy?

A. Rapid relief of severe, acute pain
B. Emergency management of anaphylaxis
C. High-concentration cancer chemotherapy
D. High-concentration antibiotic therapy for a localized, deep infection

10. When assessing the client receiving fluid therapy by hypodermoclysis, you discover that there is swelling at the infusion site and no blood return when you lower the bag. What is your best action?

A. Notify the physician.
B. Document the finding as the only action.
C. Use a penlight to determine the extent of the infiltration.
D. Discontinue the infusion and apply warm compresses to the site.

11. For which type of cancer is intrathecal chemotherapy administration used?

A. Localized skin cancer
B. Breast cancer that has metastasized to the brain
C. Prostate cancer that has metastasized to the bone
D. Any cancer type for which the person cannot receive radiation therapy
