The nurse conducts biomonitoring of residents of a community exposed to mercury vapor from a manufacturing facility nearby. Which form of biomonitoring is the method for the purpose of determining exposure to this contaminant?
A) Measuring heart rate
B) Collecting blood or urine
C) Assessing respiratory rate
D) Obtaining body weight and composition measures
Ans: B
Feedback:
Biomonitoring is the process of using medical tests such as blood or urine collection to determine whether a person has been exposed to a contaminant and how much exposure he or she has received. Measuring heart rate, respiratory rate, body weight, and body composition would not be as helpful as for determining exposure to a contaminant as would collecting blood and urine samples.
