Pediatric and Geriatric Collection Considerations — Practice Checklist

Step-by-Step Procedure (8 steps)

1. 1.

   For pediatric patients: involve a parent or guardian, explain the procedure at an age-appropriate level, and consider comfort measures (distraction, a favorite toy, having the caregiver hold the child).

2. 2.

   For infants and very young children, capillary (heel or fingerstick) collection is often preferred over venipuncture when sample volume allows.

3. 3.

   Use smaller-gauge needles and pediatric-sized tubes to match the smaller vein size and reduce the volume drawn, respecting minimum/maximum blood volume limits for the child's age and weight.

4. 4.

   For geriatric patients, assess skin integrity and vein fragility before applying the tourniquet — older, thinner skin and fragile veins bruise and roll more easily.

5. 5.

   Use a lighter tourniquet pressure and consider a smaller-gauge needle for fragile or rolling veins in older adults.

6. 6.

   Allow extra time for positioning, especially for patients with limited mobility, tremor, or difficulty extending the arm fully.

7. 7.

   Watch for and immediately address signs of fragile-vein hematoma (rapid swelling at the site) by releasing the tourniquet and applying pressure.

8. 8.

   Communicate more slowly and confirm understanding, particularly for patients with hearing or cognitive differences.

Instructor Competency Checkpoints (5)

Your instructor or preceptor will be watching for all of these during sign-off.

• 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.

Critical Mistakes — Avoid These

• ⚠

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

• ⚠

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

• ⚠

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

• ⚠

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

• ⚠

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