NSG 3100 EXAM 3- DIAGNOSTIC TESTING
QUESTIONS AND ANSWERS
The nurse's responsibility associated with diagnostic testing - Answers - - Identification
band
- Medical history
- Allergies (seafood, iodine, contrast dye)
- Consent
- Baseline vitals
- Medications
- NPO
- Preparations (ex. Were laxatives, cathartics taken)
- IV access
- Preprocedure medications (ex. Sedative or analgesic)
Assessment questions prior to diagnostics - Answers - - What is your understanding of
the test? Do you have any questions?
- What medications do you take on a daily basis (including prescription, OTC, and
herbal)? What medication did you take before the examination?
- Do you have any allergies to food or medications? What happens if you take them?
- Have you smoked or consumed alcohol in the past 24 hours?
- When was the last time you had anything to eat or drink?
- For females: is there any chance you may be pregnant? When was your last
menstrual period?
- What preparation did you make for this test (ex. Laxatives, NPO, etc.)?
Complete Blood Count (CBC) - Answers - - Hemoglobin (Hgb)
- Hematocrit (HCT)
- Erythrocytes (RBC)
- Leukocytes (WBC)
- Platelets (Thrombocytes)
What is hemoglobin (Hgb)? - Answers - - Protein primarily responsible for oxygen
transport to and carbon dioxide transport from the erythrocytes (RBC)
- Allows us to know if our patient is perfusing oxygen to all organs
- Male: 14-18
- Female: 12-16
- Average rule: above 12
What is hematocrit (HCT)? - Answers - - Blood volume
- Male: 42-52%
- Female: 37-47%
- Average rule: above 37
, What are erythrocytes? - Answers - - Red blood cells (RBC)
- Maintain normal acid-base balance
What are leukocytes? - Answers - - White blood cells (WBC)
- Inflammatory and immune response in the body
What are platelets (thrombocytes)? - Answers - - Trigger clogging factors and mediate
hemostasis
- 5 diagnostics to monitor hemostasis
- PLT's, PT, INR, APTT, Fibrinogen
What is a Basic Metabolic Panel (BMP)? - Answers - - BMP is a tool to measure
electrolytes, carbon dioxide, glucose, renal function
- Glucose
- Hemoglobin A1C (Hgb A1C)
- Kidney function
- BUN
- Creatinine
- Glomerular filtration rate (GFR)
What is glucose? - Answers - - Fasting sugar level
- Normal range: 70-110
- Usually drawn before meals and bedtime
What is hemoglobin A1C? - Answers - - 2-3 months sugar level
- Diagnostic tool for Diabetes Type II
What is BUN? - Answers - - Blood Urea Nitrogen
- Test kidney function
- 10-20 mg/ dL
- Elevated levels indicates decreased renal function
- May be elevated as a result of a high protein diet or dehydration
- Medications may increase BUN levels
- Low BUN levels may be caused by a low protein diet, malnutrition, liver damage, or
drinking excessive amounts of liquids
What is creatinine? - Answers - - Ratio of BUN and Cr is between 6-25
- Male: 0.6-1.2 mg/ dL
- Female: 0.5-1.1 mg/ dL
- It can assist in determining whether a patient is fluid volume depleted
- Tend to be more sensitive in detecting renal impairment compared to BUN
What is glomerular filtration rate (GFR)? - Answers - - Less than 60 is a sign of renal
impairment
- 24 hour urine collection test
