A patient’s laboratory results show a BUN level of 45 mg/dL. The nurse should interpret
this value as:
A. Normal finding
B. Mild hypoglycemia
C. Elevated and suggestive of impaired renal function
D. Indicative of liver failure only
Correct Answer: C. Elevated and suggestive of impaired renal function
Rationale:
Normal BUN is 10–20 mg/dL. A level of 45 mg/dL indicates azotemia, commonly due to
impaired kidney function, dehydration, or increased protein breakdown. It is not related to
glucose or liver function alone, though liver disease can also affect urea production.
A WBC count of 15,000/mm³ most likely indicates:
A. Normal immune status
B. Severe anemia
C. Infection or inflammation
D. Kidney failure
Correct Answer: C. Infection or inflammation
Rationale:
Normal WBC is 5,000–10,000/mm³. A value of 15,000 suggests leukocytosis, commonly due
to bacterial infection, inflammation, stress, or trauma.
A serum creatinine level of 2.5 mg/dL in a male patient indicates:
A. Normal kidney function
B. Improved renal filtration
,C. Impaired renal function
D. Liver dysfunction
Correct Answer: C. Impaired renal function
Rationale:
Normal male creatinine is 0.6–1.2 mg/dL. Elevated creatinine reflects reduced glomerular
filtration rate and kidney impairment.
A therapeutic digoxin level is:
A. 0.1–0.3 ng/mL
B. 0.5–2.0 ng/mL
C. 2.5–4.0 ng/mL
D. 5–10 ng/mL
Correct Answer: B. 0.5–2.0 ng/mL
Rationale:
Digoxin has a narrow therapeutic range; levels above 2.0 increase risk of toxicity
(arrhythmias, GI symptoms, visual disturbances).
An HbA1c level of 8.5% indicates:
A. Good diabetic control
B. Hypoglycemia
C. Poor long-term glucose control
D. Normal glucose metabolism
Correct Answer: C. Poor long-term glucose control
Rationale:
Normal HbA1c is 4–6%. Values above 6.5% indicate diabetes, and higher values reflect
chronic hyperglycemia.
A fasting blood glucose of 65 mg/dL indicates:
A. Hyperglycemia
B. Normal glucose level
C. Hypoglycemia
D. Kidney failure
,Correct Answer: C. Hypoglycemia
Rationale:
Normal fasting glucose is 70–105 mg/dL. Values below 70 indicate hypoglycemia, which can
cause confusion, sweating, and tremors.
A patient with HDL of 25 mg/dL is at risk for:
A. Increased cardiovascular protection
B. Hypercalcemia
C. Cardiovascular disease
D. Liver failure only
Correct Answer: C. Cardiovascular disease
Rationale:
HDL is protective cholesterol; low levels increase risk of atherosclerosis.
Total serum cholesterol of 250 mg/dL indicates:
A. Normal lipid profile
B. Hypolipidemia
C. Hypercholesterolemia
D. Liver failure
Correct Answer: C. Hypercholesterolemia
Rationale:
Normal total cholesterol is <200 mg/dL. Elevated levels increase risk of cardiovascular
disease.
LDL level of 170 mg/dL is considered:
A. Optimal
B. Elevated and a risk factor for atherosclerosis
C. Normal in all adults
D. Indicative of infection
Correct Answer: B. Elevated and a risk factor for atherosclerosis
Rationale:
, Normal LDL is <130 mg/dL. High LDL contributes to plaque formation.
ABG results showing pH 7.30, PCO₂ 50, HCO₃ 24 indicate:
A. Metabolic alkalosis
B. Respiratory acidosis
C. Metabolic acidosis
D. Respiratory alkalosis
Correct Answer: B. Respiratory acidosis
Rationale:
Low pH with elevated CO₂ indicates respiratory acidosis, often due to hypoventilation.
Serum phosphorus level of 6.0 mg/dL suggests:
A. Hypophosphatemia
B. Hyperphosphatemia
C. Normal renal function
D. Hypercalcemia
Correct Answer: B. Hyperphosphatemia
Rationale:
Normal phosphorus is 3–4.5 mg/dL. Elevated levels occur in renal failure or
hypoparathyroidism.
A platelet count of 80,000/mm³ indicates:
A. Normal clotting ability
B. Thrombocytosis
C. Thrombocytopenia and bleeding risk
D. Infection only
Correct Answer: C. Thrombocytopenia and bleeding risk
Rationale:
Normal platelets are 150,000–450,000/mm³. Low levels increase bleeding risk.
APTT of 90 seconds in a heparin patient indicates:
