Question

A55-year old man was brought to the emergency with severe multiple injuries in a road traffic accident and crush injuries, fractures of the legs and scalp lacerations. He was conscious and breathing spontaneously. PR-130/min, BP-60/40 mm Hg. Laboratory results were as follows: Serum Chemistry sodium 142 mmol/L potassium 7.9 mmol/L chloride 110 mmol/L BUN 40 mg/d Case 6 Questions (5 marks): List all the abnormal results, indicating if they are increased, decreased, critically high, or critically low (1 mark 1. 2. What is the basis of the change(s) in the resuls) (1 mark)? What other chemistry tests should be ordered for this patient AND justify your choices (3 marks)? 3.

Explanation / Answer

1-A standard sodium level is amid 135 and 145 milliequivalents per liter (mEq/L) of sodium. The standard potassium level in the blood is 3.5-5.0 milliEquivalents per liter (mEq/L). Potassium levels amid 5.1 mEq/L to 6.0 mEq/L are measured to be slight hyperkalemia. The standard adult significance for chloride is 97-107 mEq/L. Excess leads to Hyperchloremia. Regular levels of creatinine in the blood are around 0.6 to 1.2 milligrams (mg) per deciliter (dL) in adult males. BUN - adult men: 8 to 20 mg/dL.

Therefore sodium –Normal

Potassium – High

Chloride – High

BUN – High

Creatinine – Normal

2-The changes are due to MVC and a possible cardiac arrest on its way.

3-Blood tests can portion the quantity of these proteins in the circulation. Advanced than standard levels of these proteins propose a heart attack. Usually used blood examinations comprise troponin examinations, CK or CK–MB examinations, and serum myoglobin examinations. Blood examinations frequently are recurring to check for variations over period.
