Final Answer:
Elevated CPK levels indicate Muscle damage.
thus correct option is d) Muscle damage
Step-by-step explanation:
Creatine phosphokinase (CPK) is an enzyme found predominantly in the muscles. When there's muscle damage or injury, CPK is released into the bloodstream, leading to elevated levels. This could result from various causes such as strenuous exercise, trauma, muscle inflammation (myositis), or even certain medications. CPK levels can help diagnose and monitor conditions like muscular dystrophy, heart attacks, and rhabdomyolysis, where muscle breakdown occurs.
Elevated CPK levels specifically point toward muscle damage or injury rather than indicating issues with the liver, heart, or kidneys. Understanding the context of the patient's symptoms, medical history, and additional tests assists in determining the underlying cause of the elevated CPK levels. Therefore, in Dr. Lim's case, an elevated CPK draw on Mr. Roberts suggests potential muscle damage or injury.
thus correct option is d) Muscle damage
