Answer the below questions in preparation for Week 3 Lab
1. Define the following terms:
a) Parenteral Medications:
- Parental is defined as other than through the alimentary or respiratory tract; most often by
injection, a route in which medications are administered into the body.
- E.g. (intradermal/ID, subcutaneous/SC, intramuscular/IM, intravenous/IV)
b) Syringe:
- Used by nurses to administer parental medications
- Along with needles, it is used to withdraw medication from ampules and vials
c) Intradermal: under the epidermis (into the dermis)
d) Subcutaneous: (hypodermic): into the subcutaneous tissue, just below the skin
e) Intramuscular: into a muscle
f) Z Track: (p.845)
● Use the ulnar side of the nondominant hand to pull the skin approximately 2.5 cm to the side. Under some
circumstances, such as with a client who is emaciated or with an infant, the muscle may be pinched (see ❶).
Rationale: Pulling the skin and subcutaneous tissue or pinching the muscle makes it firmer and facilitates
needle insertion.
● Holding the syringe between the thumb and forefinger (as if holding a pen), pierce the skin quickly and
smoothly at a 90-degree angle (see ❷), and insert the needle into the muscle. Rationale: Using a quick motion
lessens the client’s discomfort.
● If the practice agency does not require aspiration as part of its IM injection protocol, then proceed to the next
point below; if the agency does require aspiration, hold the barrel of the syringe steady with the nondominant
hand, and aspirate by pulling back on the plunger with your dominant hand). Aspirate for 5 to 10 seconds. If
blood appears in the syringe, withdraw the needle, discard the syringe, and prepare a new injection. Rationale:
See discussion on aspiration (page 846).
● Inject the medication steadily and slowly (approximately 10 seconds per millilitre) OR rapidly if using the rapid
injection technique. Rationale: See discussion on rapid injection technique (page 846).
● After injection, wait 10 seconds and withdraw the needle, OR withdraw the needle rapidly if using the rapid
injection technique. Rationale: Some hypothesize that waiting allows the medication to disperse into the
muscle tissue, thus decreasing the client’s discomfort; others view rapid injection as less painful.
● Apply gentle pressure at the site with a dry gauze. Rationale: Use of an antiseptic swab may cause pain or a
burning sensation.
● It is not necessary to massage the area at the site of injection. Rationale: Massaging the site may cause the
leakage of medication from the site and result in irritation.
