6. (Burn off rate of 0.015% per hour)
A female college student downed multiple shots for her 21st birthday. Her BAC tested she has to go to work in 6 hours. What will her BAC be when she goes to work?

7. A female college student downed multiple shots for her 21st birthday
A female college student downed multiple shots for her 21st birthday. Her BAC tested she has to go to work in 6 hours. What will her BAC be when she goes to work?
Burn off rate of 0.015% per hour
6 x = 0.09
(BAC) – 0.09 = .06

8. A male college student downed multiple shots for his 21st birthday and was arrested for assault on the bartender because she refused to serve him more alcohol. His BAC tested 0.15 three hours later in jail. What was his BAC at the time of the assault?
Burn off rate of 0.015% per hour
3 x = 0.045
(BAC) = 0.195!

9. Range of BAC
Effects of alcohol intoxication are influenced by individual variations; some users may become intoxicated at a much lower BAC level than is indicated (below) — 0.03 BAC: No loss of coordination, slight euphoria & loss of shyness. Depressant effects not apparent. Mildly relaxed & maybe a little lightheaded — 0.06 BAC: Feeling of well-being, relaxation, lower inhibitions, sensation of warmth. Euphoria. Some minor impairment of reasoning and memory, lowering of caution. Behavior may become exaggerated and emotions intensified (Good emotions are better, bad emotions are worse)

10. 0.07 — 0.09 BAC: Slight impairment of balance, speech, vision, reaction time, and hearing. Euphoria. Judgment and self-control are reduced, and caution, reason and memory are impaired (in some* states .08 is legally impaired and it is illegal to drive at this level). You will probably believe that you are functioning better than you really are. ( * —As of July, 2004 ALL states had passed .08 BAC Per Se Laws. The final one took effect in August of 2005.) — BAC: Significant impairment of motor coordination and loss of good judgment. Speech may be slurred; balance, vision, reaction time and hearing will be impaired. Euphoria. It is illegal to operate a motor vehicle at this level of intoxication in all states.

11. 13 — 0. 15 BAC: Gross motor impairment a lack of physical control
0.13 — 0.15 BAC: Gross motor impairment a lack of physical control. Blurred vision & major loss of balance. Euphoria reduced - dysphoria* is beginning to appear. Judgment and perception are severely impaired. ( Dysphoria: Emotional state of anxiety, depression, or unease.) — 0.19 BAC: Dysphoria predominates, nausea may appear. The drinker has the appearance of a "sloppy drunk." BAC: Feeling dazed/confused or otherwise disoriented. May need help to stand/walk. If you injure yourself you may not feel the pain. Some people have nausea and vomiting at this level. The gag reflex is impaired and you can choke if you do vomit. Blackouts are likely at this level so you may not remember what has happened.

12. Kendall/Hunt Publishing Company
0.25 BAC: All mental, physical and sensory functions are severely impaired. Increased risk of asphyxiation from choking on vomit and of seriously injuring yourself by falls or other accidents BAC: STUPOR. You have little comprehension of where you are. You may pass out suddenly and be difficult to awaken BAC: Coma is possible. This is the level of surgical anesthesia BAC and up: Onset of coma, and possible death due to respiratory arrest.

19. He would have had a BAC of 0
He would have had a BAC of 0.07 on leaving the bar if he had drunk only two beers. Four hours elapsed, accounting for %, or 0.06 BAC, which added to 0.08 equals a BAC of 0.14 when he left the bar. This is equivalent to consuming four beers.
