Which parenteral route of administration uses the Z-track method?
Intravenous route
Intradermal route
Intramuscular route
Subcutaneous route - Intramuscular route
Rationale
The Z-track method is recommended during intramuscular injection to minimize local skin
irritation by sealing the medication in muscle tissue. The intravenous, intradermal, and
subcutaneous routes do not use the Z-track method
Which type of syringe is used to administer a small and precise amount of medication
subcutaneously in infants and newborns?
5-mL syringe
3-mL syringe
Insulin syringe
Tuberculin syringe - Tuberculin syringe
Rationale
A tuberculin syringe is a small-diameter syringe that is useful for preparing small, precise doses
of medication for subcutaneous injection in infants and newborns. An insulin syringe is used
only for injecting a very small dose of insulin. Both 5-mL and 3-mL syringes are used for large
volumes of parenteral medication administration.
Which site would the nurse use to administer a medication through the intraosseous route?
Pleural space
,Bone marrow
Epidural space
Subarachnoid space - Bone marrow
Rationale
Intraosseous injections involve an infusion of medication into the bone marrow. Therefore the
nurse should administer a medication into the bone marrow. Intrapleural medications are injected
directly into the pleural space through either a syringe and needle or a chest tube.
Epidural medications are administered in the epidural space through a catheter. Intrathecal
medications are administered through a catheter surgically placed in the subarachnoid space of
the brain.
Which injection is preferred for allergy skin testing?
Intradermal injection
Intravenous injection
Intramuscular injection
Subcutaneous injection - intradermal injection(rationale - intradermal injections are mostly
preferred for skin testing)
Which statement is true regarding the advantage of parenteral medication administration?
"The parenteral route is easy to administer."
"The parenteral route rarely causes anxiety in patients."
"The parenteral route provides rapid relief for local respiratory
problems."
"The parenteral route provides medication to patients with poor
peripheral perfusion." - The parenteral route provides medication to patients with poor peripheral
perfusion"(rationale - The parenteral route of administration aids patients who have poor
peripheral perfusion)
, Which route provides the most rapid absorption of a medication?
Oral administration
Topical administration
Intradermal administration
Intravenous (IV) administration - Intravenous (IV) administration
Which statement is true regarding the epidural route of parenteral administration?
The epidural route is commonly used for patients who have arterial clots.
The epidural route is most commonly used with infants and toddlers.
The epidural route commonly involves the administration of chemotherapeutic agents.
The epidural route is used for the administration of regional analgesia for surgical procedures. -
the epidural route is used for the administration of regional analgesia for surgical
procedures(rationale - Epidural medications are administered in the epidural space. They are
used for the administration of regional analgesia for surgical procedures)
Which statement is true regarding a disadvantage of the parenteral route of medication
administration?
The parenteral route causes discoloration of the teeth.
The parenteral route can only be given to unconscious patients.
The parenteral route is contraindicated before some tests or surgery
• The parenteral route may place the patient at a higher risk of reactions. - The parenteral route
may place the patient at a higher risk of reactions(rationale - parenteral involves injecting
medication in the body tissues; this route places patients at a high risk of reactions)
Which site is frequently recommended for administering heparin injections?
Thigh
Abdomen
Upper arm
Dorsal gluteal area - Abdomen(rationale - heparin is administered subcutaneously at the
abdominal site. This site has the best absorption)
