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.

Zepler [3.9K]

Answer:

Tachypnea

Explanation:

Under the assumption, your patient is an adult the normal range for respirations is 12 to 20 per minute. Anything above that number we would call tachypnea and anything below we call bradypnea. Remember our medical prefixes, tachy means fast, and brady means slow.

HOWEVER, if your patient is a child (1-12) or an infant (0-1), these respirations would be normal.

Child range: 15-30

Infant range: 25-50
