Answer:
a contaminant concentration
Explanation:
The concentration of the ingested contaminant determines the toxicity potential of the contaminant. All chemicals are acute toxicants if they are ingested in large amounts. The target organs and mechanism of action of these toxicants may vary but their potential to become toxic depends entirely on their absorption concentration. For example, Ethanol causes CNS depression but may lead to Liver cirrhosis if the concentration in body is very high.

the nurse's first priority should be control of anxiety,facilitation of learning, Medications, and Hydration.
<h3>
Epiglottis</h3>
The throat's epiglottis, a leaf-shaped flap, serves to keep food and liquids out of the windpipe and the lungs. When breathing, it remains open, allowing air to enter the larynx. It closes during swallowing to stop food from being inhaled into the lungs, forcing any liquids or food to travel down the esophagus and toward the stomach.
<h3>Interventions in Nursing</h3>
For a child with epiglottitis, the nursing interventions are:
- control of anxiety:- The family should demonstrate personal activities that will help the youngster get rid of or lessen emotions of anxiety and stress that are coming from an unknown source.
- facilitation of learning:- In addition to encouraging progress in the patient's capacity and openness to accept information, the nurse should support their ability to process and comprehend information.
- Medications:- As directed, give antibiotics such as cefuroxime.
- Hydration:- Since the child couldn't swallow, adjust the IV fluid as necessary.
