Rationale 1: The respiratory system is not the body system most profoundly affected by potassium imbalance.
Rationale 2: This value represents hyperkalemia. Both hyper- and hypokalemia are associated with fatal dysrhythmias and serious neuromuscular disorders.
Rationale 3: The hematological system is not the body system most profoundly affected by potassium imbalance.
Rationale 4: The genitourinary system is not the body system most profoundly affected by potassium imbalance.
Global Rationale: This value represents hyperkalemia. Both hyper- and hypokalemia are associated with fatal dysrhythmias and serious neuromuscular disorders. The respiratory system, hematological system, and genitourinary system are not the most profoundly affected by potassium imbalance.
