3 Gastric lavage causes an excessive loss of gastric fluid, resulting in excessive loss of hydrochloric acid (HCL) that can lead to alkalosis; the HCL is not available to neutralize the sodium bicarbonate (NaHCO3) secreted into the duodenum by the pancreas. The intestinal tract absorbs the excess bicarbonate, and alkalosis results. Gastric lavage will lead to alkalosis, which is associated with increased pH. Gastric lavage will not affect oxygen levels. Gastric lavage may lead to dehydration, which will increase osmotic pressure.

About the flashcard:

This flashcard is meant to be used for studying, quizzing and learning new information. Many scouting web questions are common questions that are typically seen in the classroom, for homework or on quizzes and tests. Flashcards vary depending on the topic, questions and age group. The cards are meant to be seen as a digital flashcard as they appear double sided, or rather hide the answer giving you the opportunity to think about the question at hand and answer it in your head or on a sheet before revealing the correct answer to yourself or studying partner. Some questions will include multiple choice options to show you the options involved and other questions will just have the questions and corrects answers. Simply reveal the answer when you are ready to check your work. Absolutely no cheating is acceptable.
