What condition is characterized by imminent vomiting associated with salivation and tachycardia?

Retching
Nausea
Vomiting
Abdominal pain

The correct answer is: Nausea

The condition characterized by imminent vomiting alongside salivation and tachycardia is commonly recognized as nausea. Nausea often precedes vomiting and can manifest with various autonomic signs, including increased salivation and changes in heart rate, such as tachycardia. The body prepares for the act of vomiting through these physiological responses, making nausea a critical precursor in this context. Retching, while related to vomiting, specifically involves the involuntary efforts to vomit without expulsion of contents and does not inherently include the symptoms of salivation or tachycardia. Vomiting itself is the expulsion of stomach contents and is a later stage in the process after nausea has occurred. Abdominal pain can occur in many conditions but is not specifically indicative of imminent vomiting like nausea is.
