Common Pediatric and Geriatric Collection Considerations Mistakes

Scenario-based exam questions on this topic test whether you adjust technique for the patient in front of you — defaulting to the standard adult procedure is itself the most common mistake.

How this procedure is evaluated

Your training program instructor or clinical preceptor observes your technique and decides whether a draw or procedure counts toward your required documentation (at least 30 venipunctures and 10 capillary punctures for NHA CPT eligibility). A technique error doesn't just risk the sample — it can mean the attempt doesn't count toward your total.

The 5 Most Common Mistakes

1

Using an adult-gauge needle and standard tube size on a small pediatric vein, risking vein damage or an unusable sample.

Why it matters: This is one of the specific checkpoints your instructor or preceptor documents during supervised practice — not a judgment call, but an explicit item on the competency sign-off.
2

Drawing more blood than the pediatric minimum/maximum volume guidelines allow for the patient's age and weight.

Why it matters: This is one of the specific checkpoints your instructor or preceptor documents during supervised practice — not a judgment call, but an explicit item on the competency sign-off.
3

Applying a routine, adult-level tourniquet pressure on fragile geriatric skin, causing bruising or a hematoma.

Why it matters: This is one of the specific checkpoints your instructor or preceptor documents during supervised practice — not a judgment call, but an explicit item on the competency sign-off.
4

Rushing a geriatric patient with mobility or cognitive considerations rather than allowing extra time.

Why it matters: This is one of the specific checkpoints your instructor or preceptor documents during supervised practice — not a judgment call, but an explicit item on the competency sign-off.
5

Failing to involve or communicate with the caregiver for a pediatric patient, increasing the child's distress.

Why it matters: This is one of the specific checkpoints your instructor or preceptor documents during supervised practice — not a judgment call, but an explicit item on the competency sign-off.

Exactly What Your Instructor Is Checking

These are the specific checkpoints your instructor or preceptor documents for this procedure.

  • ✓

    Adjusts needle gauge and tube size appropriately for pediatric patients.

  • ✓

    Respects minimum/maximum blood volume limits for pediatric patients by age/weight.

  • ✓

    Uses appropriately gentle tourniquet technique and site selection for fragile geriatric veins.

  • ✓

    Involves a parent/guardian appropriately for pediatric patients without bypassing the patient's own involvement when age-appropriate.

  • ✓

    Recognizes and responds promptly to early hematoma formation in fragile veins.

How to Avoid These Mistakes

These tips come from the most common mistake patterns in Pediatric and Geriatric Collection Considerations.

  • →

    Pediatric and geriatric scenarios are common in exam vignettes precisely because the "right" answer changes based on age-related adjustments — don't default to the standard adult procedure without reading the scenario's age cue.

  • →

    If a vein looks like it's rolling or the skin looks paper-thin, that's your cue to adjust technique before you ever insert the needle.
