What needle gauge/length do you use for an ID injection?
25-27g, 6.35 to 16mm (1/4 to 5/8in) meedle
What angle should an ID injection be done at?
5-15 degree angle
What are some examples of medications that would be administered subcutaneously?

Where should you place a SQ injection the abdomen?

What needle gauge/length do you use for an SQ injection?
Varies depending on body weight (amount of subcutaneous tissue) but generally administered with a 24-30g, 12-16mm needle
What angle should an SQ injection be done at?
If the fold is greater than an inch, 90 degrees. If the fold is less than, 45 degrees
What kind of medications are administered intramuscularly?
morphine, cyanocobalamin, hep b, tetanus vaccine
What needle gauge/length do you use for an IM injection?
Highly viscous medications need a larger gauge needle
How much fluid is generally in a intramuscular injection?
(ventral gluteal/vastus lateralis) 1ml for older infants and young children, 2ml for older children/older adults/thin people. If muscles are developed enough it can take 3ml.
Which muscle is a preferred injection site because it isn’t close to any major nerves or blood vessels?
Ventrogluteal muscle (love handles)
What is the preferred injection site for infants?
Vastus lateralis muscle
When can you start using the deltoid muscle for children?
18 months. Only use less than 1ml of solution in deltoid muscle
What is a short peripheral IV catheter?
Is less than 3 inches long and rests in the superficial vein in one of the clients extremities.
What is a central line?
Terminate in the superior vena cava. Include peripherally inserted central catheters (PICC), tunneled and nontunneled central venous catheters, and implanted ports.
Describe a PICC line
A catheters that tis inserted peripherally into a vein in the upper arm and thread it so that the catheter lies in the superior vena cava. Used for administration of long-term IV medications, vesicant meds, and parenteral nutrition.
Describe a nontunneled central venous catheter
A nontunneled cath is inserted into the subclavian vein in the upper chest or through the jug vein by a physician/NP. It is mostly uses in trauma/critical care cases. It doesn’t really matter where it was inserted as long as it’s in the superior vena cava.
What is a Luer-lock system?
Securely holds a needle in place to reduce sticks. Used on hub of IV tubing, and saline lock.
What is the difference between an ID and a IM, SQ, and IV syringe?
IM, SQ, and IV syringes are generally 3-5ml. ID syringes are 0.3-1ml and are called tuberculin syringes.
Difference between tuberculin syringes and insulin syringes
Tuberculin syringes are calibrated in hundredths of a millimeter while insulin is calculated in units.
Difference between an active and a passive device
passive device doesn’t require action by nurse.
What is a beta blocker?
Meds that decrease a patient’s heartrate and blood pressure
What are the 6 rights of administration?
Right client, right medication, right route, right time, right dose, right documentation
