Answer 1

Correct Answer: 6-8 hours

Rationale:

Electroconvulsive Therapy (ECT) is a medical treatment that involves inducing a controlled seizure in patients under general anesthesia. It is used to treat certain severe psychiatric disorders, such as major depression, bipolar disorder, and some forms of schizophrenia.
Before undergoing ECT, patients are instructed to follow specific preoperative guidelines, including being NPO (nothing by mouth) for a specified period. This is done to reduce the risk of aspiration during the procedure, as patients are under general anesthesia.
The recommended duration for NPO prior to ECT is typically 6-8 hours. This ensures that the stomach is empty, minimizing the risk of regurgitation and aspiration, which could lead to serious complications such as aspiration pneumonia.

Explanation of Other Options:

1-2 hours

Rationale: A fasting period of 1-2 hours is insufficient to ensure that the stomach is empty. Food and fluids may still be present in the stomach, increasing the risk of aspiration during anesthesia. This option is not in line with standard medical guidelines.

2-4 hours

Rationale: A fasting period of 2-4 hours is also inadequate for most patients. While this might be acceptable for clear liquids in some surgical guidelines, it is not appropriate for ECT, as it does not provide enough time for the stomach to fully empty solid foods or other substances.

10-12 hours

Rationale: A fasting period of 10-12 hours may be unnecessarily long for most patients undergoing ECT. Extended fasting can cause discomfort, dehydration, or hypoglycemia, which can negatively affect the patient's condition prior to the procedure. Standard guidelines recommend 6-8 hours as sufficient.

Conclusion:

The correct fasting period before ECT is 6-8 hours to minimize the risk of aspiration and ensure patient safety. Other options, such as shorter fasting times (1-2 or 2-4 hours), do not provide enough time for the stomach to empty, while longer fasting periods (10-12 hours) may cause unnecessary discomfort without added benefit.
