Detailed Rationales Covering

Delegation, Maternity, Pediatrics, and
Medical-Surgical Nursing
1. What are normal BUN levels?
Answer: 10-20 mg/dL
Rationale: BUN measures kidney function. Elevated levels may
indicate renal impairment, dehydration, or high protein intake.
2. What are normal WBC levels?
Answer: 5,000-10,000/mm³
Rationale: White blood cell count helps identify infection or
inflammation. Leukocytosis suggests infection; leukopenia may
indicate immunosuppression.
3. What are normal serum creatinine levels?
Answer: Males: 0.6-1.2 mg/dL; Females: 0.5-1.1 mg/dL
, Rationale: Creatinine is a more specific indicator of kidney function
than BUN. Elevated levels indicate impaired kidney function.
4. What is the therapeutic digoxin level?
Answer: 0.8-2.0 ng/mL
Rationale: Digoxin has a narrow therapeutic range. Levels below 0.8
are subtherapeutic; above 2.0 increase risk of toxicity. Signs of toxicity
include visual disturbances, bradycardia, nausea, and confusion.
5. What is a normal HbA1c level?
Answer: 4%-6%
Rationale: HbA1c reflects average blood glucose over 2-3 months.
Levels above 6.5% indicate diabetes.
6. What are normal fasting glucose levels?
Answer: 70-105 mg/dL
Rationale: Fasting glucose >126 mg/dL indicates diabetes.
Hypoglycemia is <70 mg/dL.
7. What are normal potassium levels?
Answer: 3.5-5.0 mEq/L
Rationale: Hypokalemia (<3.5) causes muscle weakness, cramps,
dysrhythmias. Hyperkalemia (>5.0) causes peaked T waves, cardiac
dysrhythmias.
8. What are normal sodium levels?
Answer: 136-145 mEq/L
Rationale: Hyponatremia can cause confusion, seizures.
Hypernatremia causes thirst, neurologic changes.
,9. What are normal calcium levels?
Answer: 9-10.5 mg/dL
Rationale: Calcium is essential for bone health, muscle contraction,
and nerve function. Hypocalcemia causes tetany,
Chvostek's/Trousseau's signs.
10. What are normal magnesium levels?
Answer: 1.3-2.1 mEq/L
Rationale: Magnesium is important for cardiac function and
neuromuscular transmission. Hypermagnesemia causes hypotension,
respiratory depression.
11. What are normal platelet levels?
Answer: 150,000-400,000/mm³
Rationale: Thrombocytopenia (<150,000) increases bleeding risk.
Patients should avoid aspirin, use electric razors, and avoid nose
blowing.
12. What are normal INR levels?
Answer: 0.7-1.8 (therapeutic on warfarin: 2-3)
Rationale: INR monitors warfarin therapy. Therapeutic range depends
on indication (e.g., atrial fibrillation 2-3, mechanical valves 2.5-3.5).
13. What are normal aPTT levels?
Answer: 30-40 seconds (therapeutic: 1.5-2× normal)
Rationale: aPTT monitors heparin therapy. Therapeutic range is
approximately 60-80 seconds.
14. What are ABG normal values?
, Answer: pH 7.35-7.45; PCO₂ 35-45 mmHg; HCO₃ 21-28 mEq/L
Rationale: pH <7.35 = acidosis, >7.45 = alkalosis. Respiratory issues
affect PCO₂; metabolic issues affect HCO₃.
15. What is a normal GFR for hemodialysis indication?
Answer: GFR <15 mL/min (often 14 mL/min or lower)
Rationale: Hemodialysis is indicated when GFR falls below 15 mL/min
in end-stage kidney disease.
16. What is the antidote for heparin?
Answer: Protamine sulfate
Rationale: Protamine sulfate binds to heparin, neutralizing its
anticoagulant effect. Used for heparin overdose or bleeding.
17. What is the antidote for warfarin (Coumadin)?
Answer: Vitamin K (phytonadione)
Rationale: Vitamin K reverses warfarin's anticoagulant effects by
promoting synthesis of clotting factors. For emergent reversal, fresh
frozen plasma may also be given.
18. What is the antidote for digoxin toxicity?
Answer: Digoxin immune Fab (Digibind)
Rationale: Digibind binds digoxin, making it unavailable for tissue
binding. Indicated for life-threatening toxicity with cardiac
dysrhythmias.
19. What is the antidote for magnesium sulfate toxicity?
