During your assessment of a 50-year-old male who was found unresponsive in an alley, you note that he has slow, shallow respirations; bradycardia; facial cyanosis; and pinpoint pupils. As your partner begins assisting the patient’s ventilations, he directs your attention to the patient’s arms, which have multiple needle tracks on them. Which of the following would most likely explain the patient’s presentation?

Use the information below to answer the two (2) following questions: Three masses are in a swimming pool filled with water (ρwater = 1000 kg/m3). All three objects are identical in size (400 cm3) but have different densities. Object A floats on the water (ρA = 580 kg/m3), Object B is completely submerged but has density equal to that of water, and Object C sinks to the bottom (ρC = 3700 kg/m3). Calculate the magnitude of the normal force that bottom of the pool exerts on Object C.

BONUSUse the information below to answer the two (2) following questions:A child playing with her drinking straw learns that she can lift some of her beverage by out of her cup by placing her finger over the top of the straw. Being very clever for her age, she realizes that beverage is actually being held up by a decrease in the pressure at the top of the enclosed end of the straw (created when the liquid falls a short distance). The straw is holding a 15 cm column of fluid. The density of the fluid in the straw is 1000 kg/m3. Atmospheric pressure is 1.013 x 105 Pa. By what factor did the volume of air at the top of the straw change after the straw was lifted out of the cup in order to produce the new pressure?
