A nurse is caring for a client with a serum potassium level of 6.9 mEq/L. When planning care, which body system will be most profoundly affected by this value?
1. The respiratory system
2. The cardiovascular system
3. The hematological system
4. The genitourinary system
Correct Answer: 2
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.
