Registered Psychiatric Nurses of Canada Examination (RPNCE) Practice test

What is typically part of an ECT workup?

1. Skull X-ray

2. Neurological assessment

3. Serum electrolytes

4. Mental state examination (MSE)

The correct answer is: Serum electrolytes

In an electroconvulsive therapy (ECT) workup, measuring serum electrolytes is a standard practice. This is crucial because fluctuations in electrolyte levels, particularly sodium and potassium, can have significant effects on cardiac function and overall health, which are important considerations before administering ECT. The procedure involves inducing seizures, and it is essential to ensure that the patient’s electrolyte balance is within safe limits to minimize potential complications. While other options might have relevance in different clinical assessments or situations, they are not typically considered part of the routine ECT workup. A skull X-ray is rarely necessary and is not a standard preparatory procedure for ECT. Neurological assessments are important in evaluating a patient’s baseline cognitive function and any potential pre-existing neurological issues, but they are not specifically required for the ECT preparation. The mental state examination (MSE) is important in assessing the patient’s current psychiatric condition, but it is not directly related to the physical health concerns that serum electrolyte levels address prior to ECT. Thus, the focus on serum electrolytes is crucial in ensuring the safety and effectiveness of the ECT procedure, highlighting its fundamental role in the workup process.
