John is a 45-year-old male admitted to the emergency department after a motor vehicle accident resulting in moderate traumatic brain injury (TBI). His medical history is unremarkable, and he is not on any chronic medications. Initial labs reveal hypernatremia (serum sodium 152 mEq/L), hypokalemia (serum potassium 3.0 mEq/L), and normal calcium levels. The ICU team requests pharmacist input on electrolyte management to reduce mortality risk.

Based on current evidence, which electrolyte imbalance identified on admission is most strongly associated with increased mortality in TBI patients and should be prioritized for correction?

Maria, a 60-year-old female with severe traumatic brain injury, is admitted to the ICU. Her initial labs show hyponatremia (serum sodium 128 mEq/L) and hypomagnesemia (serum magnesium 1.2 mg/dL). She is receiving standard supportive care, including fluid management. The multidisciplinary team asks the pharmacist about the implications of these electrolyte abnormalities on neurological outcomes.

What is the most appropriate pharmacist recommendation regarding the management of Maria’s electrolyte imbalances to optimize neurological recovery?

David, a 55-year-old male with severe TBI, is admitted to the ICU. Initial labs reveal hypochloremia (serum chloride 95 mEq/L) and hypocalcemia (serum calcium 7.8 mg/dL). The ICU team is concerned about the impact of these imbalances on mortality risk and requests pharmacist guidance on monitoring and management.

Which statement best reflects the pharmacist’s evidence-based advice regarding hypochloremia and hypocalcemia in severe TBI patients?
