Which of the following treatments helps stabilize a patient during vasovagal syncope?

The correct choice is providing a sweet beverage as a treatment to help stabilize a patient during vasovagal syncope. Vasovagal syncope is a common cause of fainting, often resulting from a sudden drop in heart rate and blood pressure, leading to reduced blood flow to the brain.

Providing a sweet beverage, such as a sugary drink, can help increase blood sugar levels and promote faster recovery from syncope. This is particularly effective in patients who may have low blood sugar levels contributing to their symptoms, as a quick intake of sugar can elevate glucose levels and improve alertness and overall stability.

While other options like cold water immersion, a moist towel on the forehead, and warm compresses may provide comfort or alleviate some symptoms, they do not address the underlying physiological issues related to vasovagal syncope as effectively as providing a sweet beverage does. In fact, cold water immersion may lead to discomfort or could be contraindicated in certain situations. Similarly, cool or warm compresses are more about symptom management rather than directly addressing the abrupt changes in blood pressure and heart rate associated with syncope.
