Question 1 of 27070

Inhalation of high concentrations of chlorofluorocarbon refrigerants (CFCs) may have which of the following effects?

🔍 Key Concepts

• Physiological effects of refrigerant (CFC) exposure on the human body • How central nervous system (CNS) and cardiovascular system can be affected by high-concentration vapors • Difference between a single specific symptom and a combination of possible symptoms in multiple-choice questions

💭 Think About

• Think about what happens if a person is in a confined space with a heavy refrigerant gas displacing oxygen—what systems in the body are likely to be affected? • Which of the listed symptoms (cardiac arrhythmias, drowsiness, loss of concentration) are plausible results of reduced oxygen and toxic vapor exposure? • Ask yourself whether exam questions about toxic exposure usually focus on just one symptom or often group several related symptoms together.

✅ Before You Answer

• Verify whether CFCs can sensitize the heart to irregular rhythms, especially under stress or exertion. • Consider whether CNS depression (such as sleepiness or inability to think clearly) is a typical outcome of inhaling high concentrations of vapors. • Before choosing, check if more than one listed symptom is medically reasonable; if so, consider whether a combined option might be appropriate.
