MULTIPLE CHOICE

1. A patient is diagnosed with cancer and requires 6 months of chemotherapy infusions. Which type of intravenous access device will likely be used?
A.
Peripheral venous access device
B.
Midline catheter
C.
Winged-needle venous access device
D.
Implantable venous infusion port

ANS: D

Feedback
A
Peripheral lines are not used for administration of chemotherapy because of the risk of extravasation.
B
A midline catheter is intended only for a 2- to 4-week interval, less than the projected length of time for chemotherapy infusion.
C
Winged needles are for use in peripheral veins that are too small for ongoing infusion of chemotherapy.
D
Implantable venous infusion ports are placed into central veins for long-term therapy. Chemotherapy treatment is often irritating and best tolerated in the larger central veins.

2. The nurse notes that a patient with cardiac disease has intravenous (IV) heparin infusing and that it is behind by 2 hours. What is the best nursing action?
A.
Increase the IV rate and recheck in 1 hour.
B.
Change the infusion rate to TKO.
C.
Discontinue the solution using aseptic technique.
D.
Contact the health care provider for consultation.

ANS: D

Feedback
A
Increasing the infusion rate might place the patient into fluid overload and might infuse too much heparin in a short time.
B
Reducing the infusion rate to TKO would put the schedule even further behind.
C
Discontinuing the solution would put the infusion even further behind.
D
The patient has a history of cardiac problems and is receiving a critical care medication, IV heparin. In this case, contacting the patient’s health care provider would be appropriate to avoid harm.

3. What is the composition of hypotonic intravenous solutions such as 0.45% NaCl?
A.
Fewer dissolved particles than blood
B.
Approximately the same number of dissolved particles as blood
C.
Higher concentrations of dissolved particles than blood
D.
Electrolytes and dextrose

ANS: A

Feedback
A
Hypotonic solutions have fewer dissolved particles than blood.
B
By definition, a hypotonic solution has fewer dissolved particles than blood.
C
By definition, a hypotonic solution has fewer dissolved particles than blood.
D
Half-normal saline does not contain dextrose.

4. Which condition would the nurse expect to be treated with an isotonic solution?
A.
Fluid overload
B.
Hemorrhagic shock
C.
Cellular dehydration
D.
Cerebral edema

ANS: B

Feedback
A
Administering isotonic solutions for fluid overload would exacerbate the problem.
B
Isotonic solutions have approximately the same osmolality as blood. Isotonic fluids are ideal replacement fluids for patients experiencing an intravascular fluid deficit that occurs in conditions such as acute blood loss from hemorrhage and gastrointestinal bleeding. Isotonic fluids increase vascular volume, thus counteracting hypovolemia and hypotension.
C
Hypotonic solutions are administered for cellular dehydration.
D
Hypertonic solutions are administered for cerebral edema.
