Study Notes
Blood Cell Count and Specimen Collection
- Basophils are identified by large blue to purple staining granules during a differential white blood cell count.
- Blood cell count specimens are collected in tubes containing anticoagulants to prevent clotting.
- Serum is the liquid part of whole blood obtained after coagulation and separation of blood components.
- The first drop of blood from a finger puncture should be wiped away to avoid contamination.
Phlebotomy Procedures
- The standard gauge for routine phlebotomy needles is 20 or 21.
- Blood alcohol tests cannot be prepared using alcohol at the site of puncture.
- Lavender top vacutainer tubes are used for hematology tests; the sample does not clot as they contain anticoagulants.
Medical Equipment and Techniques
- Total magnification in microscopy with a 10x ocular and 40x objective is 400x.
- Sonograms, or echograms, use high-frequency sound waves to examine body tissues.
- Hydrotherapy refers to the medical use of water for treatment.
Medical Imaging
- Chest X-rays are commonly taken in PA and lateral positions.
- Lead is used to prevent x-ray exposure during imaging procedures.
- Cervical x-rays focus on the neck region.
Cardiology and Pharmacy
- A Q wave shows the first downward deflection in a normal ECG tracing.
- Applying a conductive gel for ECG reduces skin resistance.
- The cardiac cycle consists of one complete heart beat, including contraction and relaxation phases.
HIPAA and Patient Privacy
- HIPAA emphasizes the security of medical records as a priority.
- Protected Health Information (PHI) must be destroyed completely when no longer needed.
Anatomy and Medical Terminology
- The sciatic nerve is a critical consideration for injections into the buttocks.
- Anatomical positions: Supine means lying on the back, prone means lying face down, and lithotomy is used for vaginal examinations.
- The prefix "peri" means around, "dys" means painful, and "itis" denotes inflammation.
Disease and Treatment
- Hypertension is commonly referred to as high blood pressure.
- Pathologists study diseases, while the pancreas secretes insulin directly into the bloodstream.
- Anticoagulants are drugs preventing blood clotting, while antacids neutralize stomach acid.
Miscellaneous Medical Knowledge
- Villi are tiny projections in the small intestine aiding nutrient absorption.
- A goiter represents visible swelling of the thyroid gland, and hepatitis refers to liver inflammation.
- The most crucial muscle for breathing is the diaphragm.
Additional Key Terms
- Metastasis refers to the spread of cancer cells from one area to another.
- Benign tumors are non-progressive and typically not life-threatening.
- Complications are adverse extensions of diseases or treatment outcomes.
- The longest bone in the human body is the femur.
Important Abbreviations
- "STAT" means immediately; "Q.H." means every hour; "Q2h" means every two hours.
