TEAS 6 Test Practice Questions and answers

Which is an anterior muscle? a. gluteus maximas b. biceps femoris c. adductor magnus d. quadriceps femoris - Correct Answer-D Anterior muscle is located near the front of the body. Of those listed, the quadriceps is the most anterior The lateral side of the right knee would be: a. the kneecap b. closest to the left knee c. farthest from the left knee d. on the underside of the knee - Correct Answer-C Something that is lateral is toward the outer side of the body. The side of the right knee farthest from th left knee would fit this description The ovaries are part of the ________system. a. skeletal b. nervous c. lymphatic d. reproductive - Correct Answer-D The ovaries are the egg-producing reproductive organs The headrest on a car may prevent traumatic injury by limiting: a. hyperflexion of the neck b. hyperextension of the neck c. vertrbral compression d. disc dengeneration - Correct Answer-B The headrest prevents the head from moving too far backward, or hyperextending the neck beyond its normal range In a whiplash injury, you might expect to see: a. cardiopulmonary problems b. side-to-side spinal curvature c. eventual injury to ligaments d. traumatic injury to ligaments - Correct Answer-D Because of the hyperflexion and hyperextension caused by such a collision, it is not uncommon to find tears or stretching of ligaments of the spine. The injury is front to back When a junked car is compacted, which statement is true? a. its mass increases b. its mass decreases c. its density increases d. its density decreases - Correct Answer-C Since density = mass/volume, it should be obvious that the decrease in volume as a car is crushed should lead to a increase in density. Nothing happens to change the mass of the car. Which is an example of deductive reasoning? A. Ten of the 100 applicants are left-handed; therefore 10% of the general population must be left-handed B. I know several left-handed artists; therefore left-handed people must have artistic aptitude C. Left-handed people are artistic; Jon is left-handed. Therefore, John must be artistic. D.

The premises may be true, in which case the reasoning is sound, or they may be untrue or at least dubious, as in this example. If gas A has four times the molar mass of gas B, you would expect it to diffuse through a plug: a. at half the rate of gas B b. at twice the rate of gas B c. at a quarter the rate of gas B d. at four times the rate of gas B - Correct Answer-A Set up as a simple equation if it helps - Suppose that gas A has a molar mass of M1 and gas B has a molar mass four times that M2. Now suppose that that M1 = 1, and M2 = 4. THe square root of 4/1 = 2/1 so the rate of effusion for gas A is half that of gas B What is the percent by volume of ethanol in 120ml of a solution containing 35ml of ethanol dissolved in water? a. 22.6% b. 29.2 % c. 35% d. 41.1% - Correct Answer-B
