Intramuscular injections involves inserting a needle into the muscle tissue to administer medications. Because muscle tissue has a large blood supply, absorption of an IM medication is faster than a subcutaneous injection.

Intramuscular injections, Insertion Insert needle at a 90 degree angle quickly in a dart-like motion
Intramuscular injections, Z-track method Used for injecting medications that is irritating to the tissues. It keeps tissue irritation to a minimum by sealing the medication deep within muscle tissue. It prevents staining or tracking of medication into tissue as the needle is withdrawn.
Intradermal injections Introduction of a hypodermic needle into the dermis for the purpose of instilling a substance such as serum, vaccine or skin test agents. Do not aspirate this type of injection. Absorption is slow.
Intradermal injections, Amount Small volumes of 0.1 mL or less are given via this route

Intradermal injections, needle Size 25 gauge that is 3/8 to 5/8 inch long
Subcutaneous injections Injections are made into the loose connective tissue between the dermis and the muscle layer. Because subcutaneous tissue is not richly supplied with blood and muscles, drug absorption is somewhat slower than with IM injections
Subcutaneous injections, Amount No more than 1 mL may be administered through this method.
Subcutaneous injections, Sites Upper arm, abdomen, thigh and scapula area. Sites must be rotated to prevent damage to tissues. Sites must be rotated to prevent damage to tissues

Intermittent Venous Access Devices Commonly called Saline locks or Heparin locks. Must be flushed with 3 mL of saline before and after use and/or q shift to ensure patency (follow local hospital policy).
Continuous infusion Medication is added to a bag of IV fluid and is infuses over the time the same period as the IV fluid
Patient Controlled Analgesia (PCA) Drug delivery system that dispenses a preset IV dose of an opioid analgesic into a client's vein when the client pushes a button on an electrical cord. RN programs the pump
Nursing responsibilities, medication administration via PCA monitor number of doses received by patient, respiration and BP; monitor for signs of oversedation; monitor for pain relief, document total volume infused and remaining every shift; ensure reversal agent Narcan is at the bedside.
Parenteral nutrition Also known as hyperalimentation Bypasses the entire GI system which eliminates the need for absorption, metabolism, and excretion. Hypertonic IV feedings to meet nutritional needs. Administered through a peripheral vein or a central vein
Bypasses the entire GI system which eliminates the need for absorption, metabolism, and excretion. Parenteral nutrition
Two types of parenteral TPN (Total parenteral nutrition) and PPN (Peripheral Parenteral nutrition)
PICC line peripherally inserted central cathether, (subclavian, Internal jugular vein)
TPN (Total parenteral nutrition) This is a preferred method for patients who are unable to tolerate and/or maintain adequate enteral or oral intake. Use for nutritional needs greater than 14 days. given through a central line
PPN (Peripheral Parenteral nutrition) May be administered through a peripheral intravenous line. Used as a temporary means (< 14 days) of delivering nutrients to patients who need more nutrients than their current oral intake can supply.
IV Lipid Emulsions Given in conjunction with TPN/PPN. Two functions: provides essential fatty acids and are sources of energy or calories. Prevents essential fatty acid deficiency which can delay wound healing
Parenteral nutrition, Nurse Monitoring, Infusion rate Infusion should be continuous; new bag and new tubing required Q 24 hrs. If infusion is discontinued abruptly, rebound hypoglycemia may result
Parenteral nutrition, Nurse Monitoring, Peripheral/central line Site monitor q4 hrs for patency, intactness, and appearance (redness, swelling, or drainage from site).
Parenteral nutrition, Nurse Monitoring, Client response monitor for signs of restlessness or discomfort. Evaluate client's response
Parenteral nutrition, Nurse Monitoring, Blood glucose check several times each day or as ordered. Regular insulin on a sliding scale may be ordered to keep blood glucose below 200 mg/dl.
Parenteral nutrition, Nurse Monitoring, Weight daily or weekly as ordered to evaluate client's response to therapy.
Parenteral nutrition, Nurse Monitoring, Intake and Output Ensure accurate and done at least every shift. Abnormal urinary output may signal hyperglycemia or altered kidney function.
Parenteral nutrition, Nurse Monitoring, Labs total protein, albumin, electrolytes, CBC, BUN are ordered daily or as needed.
Infiltration/Phlebitis wetness, pallor, pain, and coolness to touch indicate possible infiltration. Erythema, edema, inflammation often means onset of phlebitis.
Signs of systemic infections sudden onset of chills, fever, headache, nausea/vomiting.
Signs of fluid overload anxiousness, dyspnea, weak and rapid pulse.
