Question 1: Virology

Answer:

the study of viruses

Question 2: ? Lavender top tube -

Answer:

Contains the anticoagulant ethylenediaminetetraacetic acid (EDTA). EDTA inhibits coagulation by binding to calcium present in the specimen. The tubes must be filled at least two-thirds full and inverted eight times.Question 3: QRS complex:

Answer:

represents ventricular depolarization (activation). The ventricle is depolarized from the endocardium to the myocardium, to the epicardium.Question 4: This involves chemical evaluation of the contents of the urine which can be qualitative or quantitative. The chemical testing may involve examination of the following:

Answer:

vii. pHviii. Glucoseix. Ketonex. Proteinxi. Bloodxii. Bilirubinxiii. Urobilinogenxiv. Nitritexv. Leukocyte esterase

Question 5: P wave:

Answer:

the deflection produced by atrial depolarization. The normal P wave in standard, limb, and precordial leads does not exceed 0.11s in duration or 2.5mm in height.Question 6: RR interval:

Answer:

this is the interval between two R waves.P wave plus the PR segment. The normal interval is 0.12 - 0.2 sec.Question 7: Segment:

Answer:

line between two waveforms.Question 8: J (RST) junction:

Answer:

point at which QRS complex ends and ST segment begins.

Question 9: Order of draw

Answer:

• Blood Cultures2. Light Blue top tubes3. Serum or non-additive tube (Red or Red/Gray top

tubes)4. Green top tubes5. Lavender top tubes6. Gray top tubes

Question 10: BeCause BetterGoalsGeneratePerfectSpecimens

Answer:

CBC (Complete Blood Count); Includes: RBC count, WBC count and Platelet count; WBC differential count; Hemoglobin and Hematocrit determinations; ESR (Erythrocyte Sedimentation Rate); Sickle Cell Screening

Question 12: Q (q) wave:

Answer:

the initial negative deflection produced by ventricular depolarization.

Question 13: Bacteriology

Answer:

the study of bacteria Question 14: QRS interval:

Answer:

represents ventricular depolarization time. It should be no more than 0.1 sec. in the limb leads and 0.11 sec. in the precordial leads.Question 15: Waveform:

Answer:

refers to movement away from the isoelectric line either upward (positive) deflection or downward (negative) deflection.Question 16: Polyuria:

Answer:

The passage of large volumes of urine

Question 17: Specimen Requirements

Answer:

? Patient's full name and date of birth? Patient's hospital identification number (SSN for outpatients)? Date and time of collection? Medical assistant's initials Question 18: Common tests (for red):

Answer:

Serum chemistry tests; Serology tests; Blood bank (glass only) Question 19: Proteinuria:

Answer:

The presence of excess proteins in urine

Question 20: ? Red top tube -

Answer:

Also known as plain vacuum tube and contains no additive or anticoagulant. Collected blood clots by normal coagulation process in 30-60 minutes. There is no need to invert the tube after collection.

Question 21: Parasitology

Answer:

the study of parasites

Question 22: Order of draw for capillary specimens

Answer:

• Lavender tube
• Tubes with other additives3. Tubes without additives

Question 23: PR segment:

Answer:

line from the end of the P wave to the onset of the QRS complex.Question 24: Complex:

Answer:

several waveforms.Question 25: The routine urinalysis procedure is composed of three parts:

Answer:

• physical examinationb. chemical examinationc. microscopic examination

Question 26: Anuria:

Answer:

The absence of urine

Question 27: Mycology

Answer:

the study of fungi
