3.3 General Patient Care Procedures
Key Takeaways
- Patient positioning includes supine (face up), prone (face down), Fowler's (sitting 45-90°), lithotomy (on back, feet in stirrups), Sims' (left side), and Trendelenburg (head lower than feet)
- Wound care principles include clean-to-dirty technique, sterile dressing changes, proper wound assessment, and recognition of infection signs (redness, warmth, swelling, drainage, fever)
- Sterile field technique requires that all items below the waist are considered unsterile, the outer 1-inch border of the sterile field is unsterile, and wet sterile fields are contaminated
- Injection sites: deltoid and vastus lateralis (IM), outer upper arm and abdomen (SubQ), inner forearm (ID)
- Assisting with minor surgery requires surgical asepsis, proper instrument handling, sterile gloving technique, and wound closure supplies
- Medical assistants must follow the provider's orders for treatments, apply principles of body mechanics, and ensure patient safety and comfort during all procedures
General Patient Care Procedures
General patient care is the largest tested sub-area within Clinical Patient Care, accounting for 28 items on the CCMA exam. This section covers the clinical procedures medical assistants perform daily.
Patient Positioning
| Position | Description | Used For |
|---|---|---|
| Supine | Lying flat on back, face up | Abdominal exam, EKG, front of body assessment |
| Prone | Lying flat on stomach, face down | Back examination, spinal procedures |
| Fowler's | Sitting at 45-90° angle | Respiratory difficulty, post-surgical, eating |
| Semi-Fowler's | Head elevated 30-45° | Mild respiratory difficulty, comfort |
| Dorsal recumbent | Supine with knees bent and feet flat | Vaginal/rectal exam, catheterization |
| Lithotomy | Supine with feet in stirrups | Pelvic/gynecological exam, Pap smear |
| Sims' (left lateral) | Left side, left arm behind, right knee bent | Rectal exam, enema, rectal temperature |
| Trendelenburg | Supine with head lower than feet (15-30°) | Shock, improve venous return, some surgeries |
| Reverse Trendelenburg | Supine with head higher than feet | Upper abdominal surgery, reduce intracranial pressure |
| Knee-chest | Kneeling with chest on table, head turned | Rectal/sigmoid exam, proctoscopy |
| Jackknife (prone) | Lying face down, hips elevated | Rectal surgery, proctology |
Sterile Technique (Surgical Asepsis)
Principles of sterile technique:
| Rule | Application |
|---|---|
| Items below the waist are unsterile | Never lower hands below waist level when wearing sterile gloves |
| Outer 1-inch border is unsterile | The edge of the sterile field/drape is considered contaminated |
| Wet = contaminated | A wet sterile field has been compromised; replace it |
| Never turn away from a sterile field | Always face the sterile field; do not reach across it |
| If in doubt, throw it out | If sterility is questionable, the item is considered contaminated |
| Sterile touches sterile only | Sterile items can only contact other sterile items |
| Hold sterile items above waist | Keep sterile objects at or above waist level |
Opening a Sterile Pack:
- Place the pack on a clean, dry surface at waist level
- Open the first flap away from you (far side)
- Open the side flaps (left, then right — or right, then left)
- Open the last flap toward you (near side)
- Do not reach over the sterile field at any point
Sterile Gloving Technique:
- Open the glove package on a clean surface
- Pick up the first glove by the folded cuff (inner surface) with your non-dominant hand
- Slide your dominant hand in, touching only the inside of the glove
- Slide your gloved fingers under the cuff of the second glove (touching only the outer surface)
- Pull the second glove onto your non-dominant hand
- Adjust fingers without touching non-sterile surfaces
Wound Care
Types of Wounds:
| Type | Description | Example |
|---|---|---|
| Incision | Clean, straight cut made with a sharp instrument | Surgical wound |
| Laceration | Jagged, irregular tear in the skin | Cuts from broken glass |
| Abrasion | Scraping away of the skin surface | Road rash, rug burn |
| Puncture | Small hole from a sharp, pointed object | Nail, needle |
| Avulsion | Skin or tissue torn away | Degloving injury |
| Contusion | Bruise; closed wound from blunt trauma | Black eye, bruised arm |
Wound Healing Phases:
- Inflammatory phase (0-3 days) — Bleeding stops; redness, swelling, warmth (normal)
- Proliferative phase (3-21 days) — New tissue (granulation) forms; wound contracts
- Remodeling/maturation phase (21 days-2 years) — Scar tissue strengthens
Signs of Wound Infection:
- Increased redness, warmth, and swelling around the wound
- Purulent (pus-like) drainage; foul odor
- Fever
- Increased pain at the wound site
- Red streaks extending from the wound (possible lymphangitis)
Injection Techniques
Intramuscular (IM) Injections:
| Parameter | Details |
|---|---|
| Angle | 90 degrees |
| Needle size | 21-23 gauge, 1-1.5 inches |
| Volume | Up to 3 mL (deltoid: up to 1 mL) |
| Sites | Deltoid (upper arm), vastus lateralis (outer thigh), ventrogluteal (hip), dorsogluteal (buttock — least preferred) |
Subcutaneous (SubQ) Injections:
| Parameter | Details |
|---|---|
| Angle | 45 degrees (or 90° with short needle/pinched skin) |
| Needle size | 25-27 gauge, 3/8-5/8 inch |
| Volume | Up to 1 mL |
| Sites | Outer upper arm, abdomen (2 inches from navel), anterior thigh |
Intradermal (ID) Injections:
| Parameter | Details |
|---|---|
| Angle | 10-15 degrees, bevel UP |
| Needle size | 25-27 gauge, 3/8-5/8 inch |
| Volume | 0.01-0.1 mL |
| Sites | Inner forearm (TB/Mantoux test) |
| Expected result | Small wheal (bleb) should form at the injection site |
Z-Track Technique:
- Used for medications that stain or irritate tissue (e.g., iron dextran)
- Pull the skin laterally 1-1.5 inches before injecting
- Inject the medication at 90° into the muscle
- Wait 10 seconds before withdrawing the needle
- Release the skin — creates a zigzag path that prevents leakage
Assisting with Minor Office Surgery
Medical Assistant Responsibilities:
- Set up the sterile field and surgical instruments
- Prepare the patient: position, drape, explain the procedure
- Prepare the surgical site: clean with antiseptic (chlorhexidine or povidone-iodine)
- Assist with local anesthesia administration
- Hand instruments to the provider (using sterile transfer)
- Retract tissue, blot with sterile gauze, cut sutures as directed
- Apply dressings post-procedure
- Label and handle specimens per protocol
- Clean up: dispose of sharps in sharps container, biohazardous waste in red bags
- Document the procedure
Common Minor Office Procedures:
- Laceration repair (suturing)
- Incision and drainage (I&D)
- Skin biopsy (punch, shave, excisional)
- Lesion removal (cryotherapy, electrocautery)
- Suture/staple removal
- Wound irrigation and debridement
- Mole removal
Suture/Staple Removal:
- Verify provider order before removing sutures/staples
- Use suture removal kit (suture scissors, thumb forceps)
- Clean the suture line with antiseptic before removal
- Cut suture close to the skin on one side; pull toward the incision line
- Use staple remover to squeeze under each staple and lift
- Apply wound closure strips (Steri-Strips) as directed
- Document the procedure, wound appearance, and number of sutures/staples removed
