GRADED A+
A1. When can an LPN administer solutions that contain
vitamins or electrolytes?
Correct Answer: After an RN has initiated the first solution.
Rationale: In IV therapy, the Ohio Board of Nursing (and
similar state boards) requires the RN to initiate the first bag
of any solution containing additives, including vitamins and
electrolytes. The LPN may then maintain, monitor, and hang
subsequent bags.
A2. An LPN is preparing to administer D₂W (dextrose 5% in
water) through a central line. Which action should the LPN
take?
,Page 2 of 98
A) Administer the D₂W as it is within scope.
B) Refuse to administer because D₂W is not in the specified
list of solutions allowed.
C) Ask the RN to change the solution to normal saline.
D) Verify with the pharmacist and then administer.
Correct Answer: B – D₂W is not in the specified list of
solutions LPNs are permitted to give via central line.
Rationale: LPN scope for central line administration is
restricted. Only specific solutions are allowed; D₂W is not
on that list.
A3. Can an LPN inject heparin or normal saline to flush an
intermittent infusion device (saline/heparin lock)?
Correct Answer: Yes – it is within the LPN scope of practice.
,Page 3 of 98
Rationale: Flushing to maintain patency of a peripheral IV
or a saline/heparin lock is a standard maintenance task
within the LPN's role.
A4. An LPN is considering placing a venous catheter that is
4.5 inches long in a patient's hand. Is this within the LPN's
scope?
Correct Answer: No. A catheter placed by an LPN cannot
be longer than 3 inches.
Rationale: The Ohio Board of Nursing, and similar state
regulations, define a mid-line catheter as being over 3
inches and this is not within the LPN scope of practice.
A5. An LPN is caring for a patient with a central line that is
infusing TPN (Total Parenteral Nutrition). May the LPN change
the tubing on this central line?
Correct Answer: No. TPN is not within the LPN scope of
practice, therefore changing the tubing is also outside the
, Page 4 of 98
LPN scope. Tubing may be changed only if the solution is
within the LPN scope.
Rationale: TPN administration and maintenance are
generally RN responsibilities.
A6. May an LPN start an IV on a 4-year-old child?
Correct Answer: No. LPNs may only insert IVs in patients 18
years and older.
Rationale: Pediatric IV insertion requires advanced skill and
is reserved for RNs.
A7. An LPN receives an order to initiate chemotherapy
treatment for a 65-year-old patient. What is the LPN’s best
action?
Correct Answer: The LPN must refuse to initiate the
chemotherapy, as LPNs cannot initiate or administer
chemotherapeutic agents or antineoplastics.
