1. Which lab result is most indicative of anemia?
a. Hemoglobin 15 g/dL
b. Hematocrit 45%
c. Hemoglobin 9 g/dL
d. Platelets 250,000/mm³
Answer: C
Rationale: Hemoglobin of 9 g/dL is below normal ranges, indicating
reduced oxygen-carrying capacity consistent with anemia.
2. Elevated white blood cell count most commonly suggests:
a. Liver failure
b. Infection or inflammation
c. Dehydration
d. Hypoglycemia
Answer: B
Rationale: Leukocytosis typically indicates infection, inflammation,
stress, or leukemia.
,3. Which electrolyte imbalance is most associated with muscle
weakness and cardiac arrhythmias?
a. Hypernatremia
b. Hypokalemia
c. Hypercalcemia
d. Hypermagnesemia
Answer: B
Rationale: Low potassium affects neuromuscular and cardiac
function, leading to weakness and dysrhythmias.
4. Normal fasting blood glucose range is:
a. 30–60 mg/dL
b. 70–99 mg/dL
c. 120–160 mg/dL
d. 200–250 mg/dL
Answer: B
Rationale: Normal fasting glucose is 70–99 mg/dL.
5. Elevated serum creatinine primarily indicates:
a. Liver disease
b. Kidney dysfunction
c. Pancreatic failure
d. Thyroid disorder
Answer: B
Rationale: Creatinine is a marker of renal function; elevation suggests
impaired kidney filtration.
, 6. A prolonged PT (prothrombin time) suggests a problem with:
a. Platelet count
b. Liver function or clotting factors
c. Red blood cell production
d. Oxygen saturation
Answer: B
Rationale: PT reflects clotting factors produced in the liver.
7. Which condition is associated with elevated troponin levels?
a. Kidney stones
b. Myocardial infarction
c. Asthma
d. Diabetes
Answer: B
Rationale: Troponin is a cardiac enzyme released during heart muscle
damage.
8. Low hemoglobin A1c indicates:
a. Poor diabetic control
b. Long-term hyperglycemia
c. Good long-term glucose control
d. Kidney failure
Answer: C
Rationale: Lower HbA1c reflects better long-term glucose regulation.
9. Elevated LDL cholesterol increases risk for:
