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

PositionDescriptionUsed For
SupineLying flat on back, face upAbdominal exam, EKG, front of body assessment
ProneLying flat on stomach, face downBack examination, spinal procedures
Fowler'sSitting at 45-90° angleRespiratory difficulty, post-surgical, eating
Semi-Fowler'sHead elevated 30-45°Mild respiratory difficulty, comfort
Dorsal recumbentSupine with knees bent and feet flatVaginal/rectal exam, catheterization
LithotomySupine with feet in stirrupsPelvic/gynecological exam, Pap smear
Sims' (left lateral)Left side, left arm behind, right knee bentRectal exam, enema, rectal temperature
TrendelenburgSupine with head lower than feet (15-30°)Shock, improve venous return, some surgeries
Reverse TrendelenburgSupine with head higher than feetUpper abdominal surgery, reduce intracranial pressure
Knee-chestKneeling with chest on table, head turnedRectal/sigmoid exam, proctoscopy
Jackknife (prone)Lying face down, hips elevatedRectal surgery, proctology

Sterile Technique (Surgical Asepsis)

Principles of sterile technique:

RuleApplication
Items below the waist are unsterileNever lower hands below waist level when wearing sterile gloves
Outer 1-inch border is unsterileThe edge of the sterile field/drape is considered contaminated
Wet = contaminatedA wet sterile field has been compromised; replace it
Never turn away from a sterile fieldAlways face the sterile field; do not reach across it
If in doubt, throw it outIf sterility is questionable, the item is considered contaminated
Sterile touches sterile onlySterile items can only contact other sterile items
Hold sterile items above waistKeep sterile objects at or above waist level

Opening a Sterile Pack:

  1. Place the pack on a clean, dry surface at waist level
  2. Open the first flap away from you (far side)
  3. Open the side flaps (left, then right — or right, then left)
  4. Open the last flap toward you (near side)
  5. Do not reach over the sterile field at any point

Sterile Gloving Technique:

  1. Open the glove package on a clean surface
  2. Pick up the first glove by the folded cuff (inner surface) with your non-dominant hand
  3. Slide your dominant hand in, touching only the inside of the glove
  4. Slide your gloved fingers under the cuff of the second glove (touching only the outer surface)
  5. Pull the second glove onto your non-dominant hand
  6. Adjust fingers without touching non-sterile surfaces

Wound Care

Types of Wounds:

TypeDescriptionExample
IncisionClean, straight cut made with a sharp instrumentSurgical wound
LacerationJagged, irregular tear in the skinCuts from broken glass
AbrasionScraping away of the skin surfaceRoad rash, rug burn
PunctureSmall hole from a sharp, pointed objectNail, needle
AvulsionSkin or tissue torn awayDegloving injury
ContusionBruise; closed wound from blunt traumaBlack eye, bruised arm

Wound Healing Phases:

  1. Inflammatory phase (0-3 days) — Bleeding stops; redness, swelling, warmth (normal)
  2. Proliferative phase (3-21 days) — New tissue (granulation) forms; wound contracts
  3. 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:

ParameterDetails
Angle90 degrees
Needle size21-23 gauge, 1-1.5 inches
VolumeUp to 3 mL (deltoid: up to 1 mL)
SitesDeltoid (upper arm), vastus lateralis (outer thigh), ventrogluteal (hip), dorsogluteal (buttock — least preferred)

Subcutaneous (SubQ) Injections:

ParameterDetails
Angle45 degrees (or 90° with short needle/pinched skin)
Needle size25-27 gauge, 3/8-5/8 inch
VolumeUp to 1 mL
SitesOuter upper arm, abdomen (2 inches from navel), anterior thigh

Intradermal (ID) Injections:

ParameterDetails
Angle10-15 degrees, bevel UP
Needle size25-27 gauge, 3/8-5/8 inch
Volume0.01-0.1 mL
SitesInner forearm (TB/Mantoux test)
Expected resultSmall 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:

  1. Set up the sterile field and surgical instruments
  2. Prepare the patient: position, drape, explain the procedure
  3. Prepare the surgical site: clean with antiseptic (chlorhexidine or povidone-iodine)
  4. Assist with local anesthesia administration
  5. Hand instruments to the provider (using sterile transfer)
  6. Retract tissue, blot with sterile gauze, cut sutures as directed
  7. Apply dressings post-procedure
  8. Label and handle specimens per protocol
  9. Clean up: dispose of sharps in sharps container, biohazardous waste in red bags
  10. 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
