- OSHA governs workplace safety in laboratory settings.
- Contaminated blood cultures often result from improper site preparation.
Effective Practices
- Apply firm pressure after blood draws to prevent bruising.
- Tubes should be labeled after the draw, but before leaving the patient's room.
- Sharps containers should be disposed of when 3/4 full.
Laboratory Tests and Conditions
- The Complete Blood Count (CBC) does not require fasting.
- Blood culture contamination is frequently due to inadequate skin preparation.
- Conditions like thrombocytopenia can be indicated by the presence of platelets during a sample analysis.
Equipment and Techniques
- A heel stick is used for infants; the maximum penetration depth is 2.0 mm.
- Capillaries are where nutrient and gas exchange occurs; they are a single cell thick.
- Use a syringe for patients with fragile veins.
Additional Important Facts
- The most common laboratory infection from HAIs is Hepatitis.
- The functional unit of the nervous system is a Neuron.
- Plasma constitutes approximately 45% of total blood volume.
Special Tests and Considerations
- The 5-hour oral glucose tolerance test (GTT) is utilized to diagnose hypoglycemia.
- A Bilirubin test sample must be protected from light.
- The most common chemistry test conducted via POCT is Glucose.
Personal Care and Follow-Up
- When interacting with a patient, ensure comfort and proper communication.
