Final answer:

Ingesting a bag of salted potato chips is a strong stimulus for thirst as it increases blood sodium levels and osmolality, leading to a thirst response triggered by osmoreceptors.

Step-by-step explanation:

Stimulus for Osmometric Thirst

A strong stimulus for product thirst would be an event or action that causes a significant loss of bodily fluids, leading to an increase in the concentration of solutes in the blood.

  • Evaporation from the lungs is a gradual process and unlikely to trigger a strong biometric thirst response quickly.
  • Vomiting during illness causes a significant loss of body fluids and electrolytes, leading to an increase in blood osmolality, which can trigger biometric thirst.
  • Loss of blood after an automobile trauma can lead to a decrease in blood volume and pressure, activating both biometric and volumetric thirst, but it is also a medical emergency where the body's priority is to maintain blood pressure.
  • Ingesting a bag of salted potato chips introduces a high amount of sodium, which has a strong osmotic effect on the body. This can lead to an increase in blood osmolality and induce osmometric thirst.
  • Infusion of blood into the vascular system actually increases blood volume and should not stimulate biometric thirst as it does not increase blood osmolality under normal circumstances.

Therefore, the ingestion of a bag of salted potato chips is a strong stimulus for biometric thirst due to the resulting increase in blood sodium levels which consequently attracts more water .
