CRNI (2026/2027) Exam with Correct Verified and Well Analyzed
ANSWERs Graded A+
Before the administration of intravenous fluid, it is most important for the nurse to obtain which
information from the health care provider's orders?
a. Intravenous catheter size
b. Osmolarity of the solution
c. Vein to be used for therapy
d. Specific type of IV fluid - ANSWER d. Specific type of IV fluid
Rational: An order for infusion therapy must contain the following to be complete: specific type of
fluid, rate of administration, and drugs added to the solution. Osmolarity of the solution is not
necessary because it is incorporated into the specific type of fluid. It is the nurse's independent
decision about the most appropriate vein to cannulate and the catheter size to use.
Which IV order does the nurse question?
a. Flush Groshong catheter with 10 mL normal saline every 8 hours.
b. Infuse 20 mEq potassium chloride in 1000 mL D5W at 50 mL/hr.
c. Infuse 500 mL normal saline over 1 hour.
d. Infuse 0.9% normal saline at keep vein open (KVO) rate. - ANSWER d. Infuse 0.9% normal saline at
keep vein open (KVO) rate.
Rational: To be complete, IV orders for infusion fluids should specify the rate of infusion. This order
does not specify the rate of infusion and is not considered complete.
Which infusion device does the nurse select for the older adult client with a medical diagnosis of
"dehydration"?
a. Cassette pump
b. Elastomeric balloons
c. Volumetric controller
d. Syringe pump - ANSWER a. Cassette pump
Rational: An older adult client who has dehydration will require a large fluid volume that is accurately
measured by using a cassette pump during the infusion. Volumetric controllers count drops for
,administered volume and are inherently inaccurate because of variation in drop size. A syringe pump
is accurate but not appropriate for a large volume. Elastomeric balloons are used to deliver
intermittent medications.
A nursing administrator is concerned about the incidence of complications related to IV therapy,
including bloodstream infection. Which action by the administrator would have the biggest impact
on decreasing complications?
a. Investigate initiating a dedicated IV team.
b. Require inservice education for all RNs.
c. Limit IV starts to the most experienced nurses.
d. Perform quality control testing on skin preparation products. - ANSWER a. Investigate initiating a
dedicated IV team.
Rational: The Centers for Disease Control and Prevention (CDC) recommends having a dedicated IV
team to reduce complications, save money, and improve client satisfaction and outcomes. In-service
education would always be helpful, but it would not have the same outcomes as an IV team. Limiting
IV starts to the most experienced nurses does not allow newer nurses to gain this expertise. The
quality of skin preparation products is only one aspect of IV insertion that could contribute to
infection.
The nurse wants to find written standards for IV therapy. The nursing manager suggests that the
nurse investigate publications from which resource?
a. IV Therapy Nursing Society
b. Infusion Nurses Society
c. Nurse's State Board of Nursing
d. Hospital's IV solutions vendor - ANSWER b. Infusion Nurses Society
The Infusion Nurses Society publishes guidelines and standards related to IV therapy and offers a
national certification examination. The State Board of Nursing publishes legal information related to
nursing practice, and the solutions vendor would have written information pertaining only to specific
products. The IV Therapy Nursing Society does not exist, and the other organizations listed do not
provide standards and guidelines related to IV therapy.
The RN assigned a new nurse to a client who was receiving chemotherapy through an intravenous
extension set attached to a Huber needle. Which information about disconnecting the Huber needle
is most important for the RN to provide to the new nurse?
a. "Apply topical anesthetic cream to the area after discontinuing the system."
, b. "Be aware of a rebound effect when discontinuing the system."
c. "Be sure to flush the system with saline after removing the Huber needle."
d. "Place pressure over the site to prevent bleeding." - ANSWER b. "Be aware of a rebound effect
when discontinuing the system."
Rational: Huber needles are used to access implanted ports placed under the skin. Because the
dense septum holds tightly to the needle, a rebound can occur when it is pulled from the septum,
often resulting in needle stick injury to the nurse. Topical anesthetic cream can be used when
accessing the system. Flushing is carried out when the system is accessed and once monthly. Because
the implanted port is not being removed, there is no need for a pressure dressing.
After discontinuing a nontunneled, percutaneous central catheter, it is most important for the nurse
to record which information?
a. Application of a sterile dressing
b. Length of the catheter
c. Occurrence of venospasms
d. Type of ointment used to seal the tract - ANSWER b. Length of the catheter
Rational: After removal of a catheter, measure the catheter length and compare it with the length
documented on insertion. If the entire length has not been removed, the nurse should contact the
physician immediately because some of the catheter may still be in the client's vein.
When assessing the client's peripheral IV site, the nurse observes a streak of red along the vein path
and palpates a 4-cm venous cord. What is the most accurate documentation of this finding?
a. Grade 3 phlebitis at IV site
b. Infection at IV site
c. Thrombosed area at IV site
d. Infiltration at IV site - ANSWER a. Grade 3 phlebitis at IV site
Rational: The presence of a red streak and palpable cord indicates grade 3 phlebitis. No information
in the description indicates that infection, infiltration, or thrombosis is present.
What information is most important to teach the client going home with a peripherally inserted
central catheter (PICC) line?
a. "Avoid carrying your grandchild with the arm that has the IV."
