Ch 22 - Parenteral Medications questions with correctanswers
Which syringe should the nurse select for an injection of 0.45 mL of
medication to a pediatric patient?
a. Tuberculin syringe
b. Insulin syringe
c. Low-dose insulin syringe
d. 3-mL syringe Correct Answer-ANS: A
The tuberculin syringe has a long, thin barrel with a preattached thin
needle. The syringe is calibrated in sixteenths of a minim and
hundredths of a milliliter and has a capacity of 1 mL. You use tuberculin
syringes to prepare small amounts of medication, such as small, precise
doses for infants or young children. You also use them for ID and
subcutaneous injections.
An insulin syringe is used to administer insulin. A low-dose insulin
syringe is used to administer insulin. A syringe this large (3-mL) would
not be used for the pediatric dose.
The nurse is preparing to give an IM injection to a 6-month-old infant.
Which site is the most appropriate for administration of the injection to
this patient?
a. The deltoid muscle
b. The dorsogluteal injection site
c. The vastus lateralis
d. All of the above Correct Answer-ANS: C
,Based on the evidence, the recommendation for pediatric IM injection
sites includes use of the vastus lateralis for infants up to 12 months of
age, the deltoid in children 12 months and older, and the ventrogluteal
site for children of all ages.
The deltoid muscle is an acceptable site only in children 12 months and
older. The dorsogluteal site should not be used as a site for IM injection.
An appropriate technique for administration of a parenteral medication is
observed when the nurse:
a. Uses strict aseptic technique
b. Tightly holds the inside surface of the syringe plunger
c. Injects medication as rapidly as possible
d. Slowly inserts the needle through the patient's tissue Correct Answer-
ANS: A
Strict aseptic technique is used during all steps of preparation and
administration of parenteral medications
Touching the inside surface of the plunger should be avoided.
Medication should be injected slowly and smoothly. The needle should
be inserted smoothly and quickly.
What is the appropriate technique for the nurse to use to remove
medication from an ampule?
a. Keep the needle against the rim of the ampule
b. Break the neck of the ampule toward the hands
c. Tip the ampule to bring all fluid within reach of the needle
, d. Add a volume of air to push the medication out into the syringe
Correct Answer-ANS: C
Keep the needle tip under the surface of the fluid and tip the ampule so
that all the fluid is within reach, to prevent aspiration of air.
The broken rim of the ampule is considered contaminated. When the
ampule is inverted, the solution can drip out of the ampule if the needle
touches the rim of the ampule. The ampule should be broken away from
the hands to avoid injury to the nurse. Air should not be added to the
ampule; increasing air pressure may force fluid out of the ampule.
A patient is demonstrating the technique for mixing regular and NPH
insulins in the same syringe. A nurse evaluates that further instruction is
required if the patient first:
a. Aspirates and injects air equal to the regular insulin dose into the vial
first and withdraws the regular insulin
b. Aspirates and injects air equal to the NPH insulin into the vial but
does not withdraw the medication
c. Withdraws the proper amount of NPH insulin before withdrawing the
regular insulin
d. Calculates the combined total of insulin after withdrawing the NPH
insulin Correct Answer-ANS: A
If mixing rapid- or short-acting insulin with intermediate- or long-acting
insulin, take insulin syringe and aspirate volume of air equivalent to
dose to be withdrawn from intermediate- or long-acting insulin first.
