level questions: TOXICOLOGY 1 - AIR POLLUTANTS

QuestionAnswer
colorless, tasteless, odorless & non-irritating gasCarbon monoxide / CO
combines irreversibly on oxygen-binding sites of hemoglobin; has affinity 220x more than of oxygenCarbon monoxide / CO
Specific antagonist of CO; Treatment for CO poisoningOxygen
The by-product of CO-Hb complex; Interferes with the dissociation from the remaining oxyhemoglobinCarboxyhemoglobin
Reduces the transfer of oxygen to the tissuesCarboxyhemoglobin
Treatment for CO poisoningHypothermic Therapy, Oxygen
TRUE or FALSE: During CO poisoning of a patient, OXYGEN THERAPY on high concentrations may contribute to the development of ARDSTRUE
<15% Carboxyhemoglobinhead ache, malaise
25% Carboxyhemoglobindecreased attention span & fine motor coordination
40% Carboxyhemoglobincollapse & syncope
>60% CarboxyhemoglobinDeath - irreversible damage to the brain & heart
How to perform Oxygen Therapy on a CO-intoxicated patient?High concentrations of O2 for a SHORT period of time
colorless, irritant gas generated from combuston of sulfur-containing fossil fuelsSulfur Dioxide / SO2
Inhalation of Sulfur Dioxide / SO2 would cause?bronchoconstriction, profuse brochorrhea
Clinical effects of Sulfur Dioxide / SO2Inc. bronchial secretions
Treatment for Sulfur Dioxide / SO2 poisoning?Supportive / symptomatic treatment
After contact of Sulfur Dioxide / SO2 on moist membranes, it forms __________sulfuric acid
In Sulfur Dioxide / SO2 poisoning, this substance is responsible for the SEVERE IRRITANT EFFECTS on the eyes, mucus membranes & skinSulfuric Acid
Formed from fresh "silage" (grass / other green fodder) stored in an airtight siloNitrogen Oxide
Inhalation damages the lung infrastructure that produces the surfactant; therefore, capable of producing: 1. NON-CARDIOGENIC PULMONARY EDEMA, 2. ACUTE ARDSNitrogen Oxide
Type of alveolar cells affected upon exposure to Nitrogen OxideType 1 Alveolar Cells
It is an absorbant of UV light at high altitude. However, it is a pollutant on ground levelOzone / O3
