Rationale: The appropriate intervention when a patient experiences a fall is to assess for injuries. This immediate action helps in identifying any harm or complications resulting from the fall, allowing for timely intervention. Calling for help may be necessary after assessing the injuries, but the priority is to evaluate the patient's condition.

Notifying the healthcare provider can be done once the assessment has been completed and any necessary initial interventions have been initiated.

Choice
D) is an excess of magnesium, usually not a common electrolyte imbalance induced by diuretics.

Correct Answer: C
