Correct Answers | Graded A+
1. What are two health conditions that a total protein test can help identify?
Diabetes or hypertension
Malnutrition or liver disease
Anemia or infection
Heart disease or stroke
2. What are the two primary functions that calcium testing can help assess?
Parathyroid function and calcium metabolism
Electrolyte balance and blood pressure
Hormonal levels and glucose metabolism
Liver function and kidney function
3. Which components are measured in a complete blood count (CBC)?
White blood cells (WBC), red blood cells (RBC), and platelets.
Glucose, cholesterol, and triglycerides.
Bicarbonate, aldosterone, and creatinine.
Hemoglobin, hematocrit, and electrolytes.
4. What is the role of aldosterone?
It causes the kidneys to retain only water
It causes constriction of the vessels
It causes the kidneys to retain potassium and water
, It causes the kidneys to retain sodium and water
5. If a patient presents with symptoms of fatigue and jaundice, which laboratory
test would be most relevant to assess their condition and why?
Complete blood count, to check for anemia.
Total protein test, as it can indicate liver disease.
Electrolyte panel, to assess hydration status.
Blood glucose test, to evaluate for diabetes.
6. What is the primary purpose of conducting a bilirubin test?
To assess liver function
To monitor vital signs
To evaluate kidney function
To measure electrolyte balance
7. What do BUN and creatinine tests specifically assess in the body?
Electrolyte balance
Liver function
Blood glucose levels
Kidney function
8. Which conditions are associated with phosphate testing?
Liver failure, anemia, and dehydration
Asthma, COPD, and pneumonia
Kidney failure, bone metastasis, and hypercalcemia
, Diabetes, hypertension, and hyperlipidemia
9. The adult hemoglobin reference range for adult whole blood is:
12.0-18.0 g/dl
8-12 g/dl
10-14 g/dl
16-20 g/dl
none of the above
10. Describe the significance of phosphate testing in relation to kidney function
and bone health.
Phosphate testing is primarily used to assess liver function and
electrolyte balance.
Phosphate testing only measures dietary intake of phosphorus.
Phosphate testing is irrelevant to kidney function but important for
diagnosing respiratory diseases.
Phosphate testing is significant as it helps identify kidney failure
and bone metastasis, indicating issues with kidney function and
bone health.
11. Describe the significance of cholesterol testing in relation to cardiovascular
health.
Cholesterol testing is used to diagnose diabetes mellitus.
Cholesterol testing is significant as it helps assess the risk of
developing atherosclerotic heart disease.
Cholesterol testing is irrelevant to cardiovascular health.
Cholesterol testing measures kidney function.
