The physician orders mefoxin (Cefoxitin) 800 mg IV Q 8 hours. To reconstitute the medications the instructions state to add 7.5 mL of NSS for a total of 8 mL with each mL containing 250 mg. How many millilitres will be given?

Choice A reason: Hypocalcemia may occur in AKI due to impaired vitamin D activation, but it is not a primary concern in the diuresis phase, where kidneys produce large urine volumes. Calcium imbalances are less immediate than fluid losses, which can rapidly destabilize hemodynamics during this phase.

Choice B reason: In the diuresis phase of AKI, kidneys regain function, producing excessive urine, which can lead to hypovolemia. Fluid loss depletes intravascular volume, causing hypotension, tachycardia, and organ hypoperfusion. Monitoring is critical to prevent dehydration and ensure adequate fluid replacement to maintain hemodynamic stability during recovery.

Choice C reason: Increased blood pressure is more common in the oliguric phase of AKI due to fluid overload. In the diuresis phase, excessive urine output reduces volume, potentially lowering blood pressure. Hypertension is not a typical complication during this phase, making it an incorrect focus for monitoring.

Choice D reason: Hyperkalemia is a concern in the oliguric phase of AKI due to reduced potassium excretion. In the diuresis phase, increased urine output facilitates potassium clearance, reducing hyperkalemia risk. Hypovolemia from excessive fluid loss is a more immediate concern during this phase of AKI recovery.

Choice A reason: Releasing the client when behavioral control is achieved aligns with autonomy and beneficence, not nonmaleficence. While it benefits the client, it does not directly address harm prevention, which is the core of nonmaleficence. The focus is on restoring freedom, not specifically ensuring no physical harm during restraint use.

Choice B reason: Explaining release requirements promotes understanding and autonomy but does not directly prevent harm, the focus of nonmaleficence. It supports therapeutic communication but does not address the physical safety risks of restraints, such as skin breakdown or circulation issues, making it less relevant to this principle.

Choice C reason: Applying restraints based on assessment, not attitude, ensures objectivity, aligning with justice and fairness. While this prevents inappropriate restraint use, it is less directly tied to nonmaleficence, which focuses on avoiding harm like injury during restraint application, making it a secondary consideration in this context.

Choice D reason: Assuring restraints do not cause injury directly upholds nonmaleficence, the ethical principle of avoiding harm. Regular checks for skin breakdown, circulation impairment, or nerve damage prevent physical harm, ensuring safety during restraint use, making this action the most aligned with nonmaleficence in a restrained client.
