What could be some possible causes of the hyperkalemia? Patient B is also complaining of numbness and tingling, especially around the mouth. What are the other two electrolyte imbalances in this patient that could be causing these symptoms? Discuss the possible etiology associated with each electrolyte imbalance identified in question number 3.
You have just arrived to work and been assigned to care for three patients: A, B, and C. Selected lab work for each patient is listed below.

| Ca+ | 8.9 mg/dL | 7.5 mg/dL | 9.5 mg/dL |
| Mg+ | 1.3 mg/dL | 0.9 mg/dL | 2.1 mg/dL |
| pH | 7.40 | 7.32 | 7.42 |
| PCO2 | 42 mm Hg | 48 mm Hg | 40 mm Hg |
| PO2 | 95% | 98% | 99% |
| HCO3 | 22 | 28 | 26 |
