MULTIPLE CHOICE

1. The nurse is preparing an injection of 0.45 mL of medication for a pediatric patient. Which syringe is most appropriate?

ANS:  A

The tuberculin syringe is calibrated in hundredths of a milliliter and has a capacity of 1 mL. It is used to prepare small amounts of medication such as small, precise doses for infants or young children. It is also used for intradermal and subcutaneous injections. An insulin syringe is used to administer insulin and is calibrated in units. A 3-mL syringe and a 10-mL syringe are calibrated in 0.2 of a milliliter and are not accurate for small volumes.

DIF:    Cognitive Level: Applying               REF:   Text reference: p. 542

OBJ:   Explain the importance of selecting the proper size syringe and needle for an injection.

2. The nurse is preparing to administer an intramuscular (IM) injection to a 6-month-old infant. Which injection site is the most appropriate for this patient?

ANS:  C

On the basis of the evidence, the vastus lateralis is the recommended site for pediatric IM injections for infants up to 12 months of age. The deltoid is the recommended site for children 18 months of age and older. The dorsogluteal site should not be used as an IM injection site. The abdomen is used for subcutaneous injection, not for IM injection.

DIF:    Cognitive Level: Applying               REF:   Text reference: p. 539

OBJ:   Discuss factors to consider when selecting injection sites.

3. The nurse is administering a parenteral medication to the patient. Which action by the nurse demonstrates proper technique?

ANS:  A

Strict aseptic technique is used during all steps of preparation and administration of parenteral medications. Work-arounds bypass a procedure, policy, or protocol and should not be used. Medication should be injected slowly and smoothly. The needle should be inserted smoothly and quickly.

DIF:    Cognitive Level: Applying               REF:   Text reference: p. 540

OBJ:   Identify advantages, disadvantages, and risks of administering medication by each injection route. TOP:           Aseptic Technique in Injections

4. The nurse is preparing a medication that comes in an ampule. Which action by the nurse is appropriate?

ANS:  C

Filter needles filter out any fragments of glass, and reaching the bottom of the ampule allows the medication to be completely withdrawn. The top of the ampule is tapped to move the fluid from the neck into the bottom of the ampule, where it is withdrawn. The ampule is held upside down or is set on a flat surface for withdrawal of the medication. The medication will not spill from the ampule after opening unless the needle tip or shaft touches the rim. The rim is considered contaminated and should not be touched by the needle.

DIF:    Cognitive Level: Applying               REF:   Text reference: p. 544

OBJ:   Correctly prepare injectable medications from a vial and an ampule.

5. The nurse is teaching a patient how to mix 5 units of regular insulin and 15 units of NPH insulin in the same syringe. The nurse determines that further instruction is needed if the patient does which of the following?

ANS:  A

When rapid- or short-acting insulin is mixed with intermediate- or long-acting insulin, air should be injected into the intermediate- or long-acting insulin vial first without withdrawal of the medication. Regular insulin is withdrawn first, and then the combined total insulin dose is calculated before the NPH insulin is withdrawn from the vial.

DIF:    Cognitive Level: Applying               REF:   Text reference: pp. 549-551

OBJ:   Correctly administer intradermal, subcutaneous, and intramuscular injections.
