General Patient Care — 28 Items, the Biggest Block on the CCMA Exam

✗ Intradermal vs subcutaneous — treating them as "both the shallow shots."

✓ Intradermal is nearly flat: 5 to 15 degrees, bevel UP, 27 gauge, 1/4 to 1/2 inch, 0.1 mL — and it MUST raise a 6 to 10 mm wheal. Subcutaneous is 45 degrees into pinched-up fat, 23 to 25 gauge, 5/8 inch — and raises NO wheal. A wheal after a subcutaneous dose means you went too shallow. No wheal (or one under 6 mm) after a TB test means the dose went too deep; CDC says repeat immediately at a site at least 2 inches (5 cm) from the first.

✗ Ventrogluteal vs dorsogluteal — and forgetting that neither is used for vaccines.

✓ Ventrogluteal is landmarked from the greater trochanter, anterior superior iliac spine and iliac crest. It holds larger volumes and sits farthest from the sciatic nerve, so it is the preferred gluteal site for non-vaccine IM drugs. Dorsogluteal (upper outer buttock) is avoided because the sciatic nerve and superior gluteal artery lie within millimeters in cadaver measurements. Separate point that trips people up: for VACCINES, CDC does not use the buttock at all — the answer is deltoid or vastus lateralis.

✗ Aspirating before a vaccine vs holding the needle 10 seconds in Z-track.

✓ CDC states aspiration before injecting a vaccine is NOT necessary — there are no large vessels at the recommended sites and aspiration increases pain. The roughly 10-second pause is a different thing entirely: it belongs to Z-track, AFTER injecting, so the drug disperses before you withdraw the needle and let the displaced tissue snap back over the track. Z-track is a nursing practice convention, not a CDC vaccine instruction.

✗ Placing a TB skin test vs reading and interpreting it.

✓ A CCMA may place the intradermal test and, where trained and permitted, measure the INDURATION (the firm raised area) in millimeters at 48 to 72 hours and record the measurement — measure induration, not redness. A CCMA does NOT tell the patient the test is "positive" or explain what it means; the millimeter cutoff that counts as positive depends on the patient's risk category and that determination belongs to the provider. Report the millimeters; let the provider deliver the meaning.

✗ "The provider said give the usual dose" vs a complete, actionable order.

✓ A usable order names the drug, the dose, the route, the site or frequency, and the ordering provider. "The usual" is not an order. A CCMA may not select or adjust a dose, convert a route, or substitute a drug — including working around an unavailable vial strength without recalculating and confirming with the provider. Unclear or illegible orders get clarified BEFORE anything is drawn up.

✗ Documenting when you prepare the dose vs documenting after you give it.

✓ Document AFTER administration, never before. Charting a dose you have not yet given is falsification of the record, and if you are interrupted it sets up a double dose. Chart the drug, dose, route, exact site, date and time, lot number and manufacturer for vaccines, the patient's response, and your signature with credential.

✗ Single-dose vial vs multi-dose vial.

✓ A single-dose vial is one patient, one time — leftover volume is discarded and never pooled, even if the vial still looks full. A punctured multi-dose vial is dated and discarded within 28 days unless the manufacturer's package insert gives a different beyond-use date (for vaccines, the insert governs), and every single entry uses a new needle and a new syringe. CDC's rule: one needle, one syringe, only one time.

✗ Medical asepsis (clean) vs surgical asepsis (sterile).

✓ Medical asepsis REDUCES the number of organisms: hand hygiene, clean gloves, disinfected surfaces — used for injections and routine exams. Surgical asepsis ELIMINATES all organisms including spores: sterile gloves, a sterile field, autoclaved instruments — used for minor surgery, wound repair and entry into a sterile body cavity. Placing a merely "clean" item on a sterile field contaminates the whole field.

✗ Expected inflammation vs wound infection.

✓ Redness, warmth, mild swelling and pain in the first days are the normal inflammatory phase of healing. Infection is the pattern that WORSENS rather than fades: spreading erythema, induration, increasing pain, purulent or malodorous drainage, and fever. Document and report your objective findings to the provider — do not tell the patient the wound is infected, and do not recommend an antibiotic.

✗ Sims' vs lithotomy vs dorsal recumbent.

✓ Sims' is LEFT side-lying with the right knee and hip flexed — rectal exams, enemas. Lithotomy is supine with feet in stirrups and hips flexed and abducted — vaginal, pelvic and some urologic exams. Dorsal recumbent is supine with knees bent and feet flat on the table — abdominal palpation and some genital exams. All three expose the patient, so all three require draping and the shortest tolerable time in position.

✗ Refrigerated vs frozen vaccine storage ranges — and what to do on a temperature excursion.

✓ CDC: refrigerator 2 to 8 degrees C (36 to 46 F), set at the 5 C / 40 F midpoint. Freezer -50 to -15 degrees C (-58 to +5 F). Dormitory-style or bar-style units are not permitted for any vaccine. If a reading is out of range, do not decide on your own that the vaccine is fine: label it "DO NOT USE," keep it separated but stored at the proper temperature, document the excursion, and contact the manufacturer or your immunization program for a viability decision.

✗ Deltoid landmark — "a couple of inches down" vs measuring from the acromion.

✓ CDC places the deltoid injection in the central, thickest part of the muscle, approximately 2 inches (5 cm) BELOW the acromion process and ABOVE the level of the axilla. Some medical assisting textbooks print 1 to 2 inches; the risk runs in one direction only, because injecting too high reaches the subdeltoid bursa and causes shoulder injury. Measure down from the acromion, never up from the elbow, and never inject into the upper third of the arm near the shoulder tip.
