An individual suffers severe blunt trauma to the thoracic cavity. Which of the following organs are at greatest risk from this injury?
A. Heart and lungs
B. Brain and spinal cord
C. Liver and stomach
D. Large and small intestines
The correct answer is a. Heart and lungs. The thoracic cavity contains the heart and lungs, which are at greatest risk from severe blunt trauma to this area.
a.The brain and spinal cord are not located in the thoracic cavity and are therefore not at greatest risk from blunt trauma to this area.
c.The liver and stomach are located in the abdominal cavity, which is below the thoracic cavity. While these organs may be affected by severe blunt trauma to the thoracic cavity, they are not at greatest risk.
d.The large and small intestines are also located in the abdominal cavity and are not at greatest risk from blunt trauma to the thoracic cavity.
Therefore, the Correct Answer is A.

Q #2: For which of the following reasons does a chloride ion have a negative charge?
A. It gained an electron
B. It lost an electron.
C. It lost a proton.
D. It gained a proton.
Answer Explanation
A chloride ion has a negative charge because it gained an electron. When an atom gains an electron, it becomes negatively charged because it now has more electrons than protons. In the case of a chloride ion, the neutral chlorine atom gains an electron to become a negatively charged chloride ion.
The other options are incorrect because they do not result in a negative charge. Losing an electron would result in a positive charge. Losing or gaining a proton would change the identity of the atom and is not related to the formation of a chloride ion.

Q #3: Which of the following tools can be used to measure the turbidity of a liquid by measuring the transmission of light through the sample?
A. Centrifuge
B. Spectrophotometer
C. Microdensitometer
D. Electrophorometer
Answer Explanation
The correct answer is b. Spectrophotometer. A spectrophotometer is a tool that can be used to measure the turbidity of a liquid by measuring the transmission of light through the sample. Turbidity is a measure of the cloudiness or haziness of a liquid caused by the presence of suspended particles. A spectrophotometer measures the amount of light that passes through the sample and compares it to the amount of light that passes through a reference sample to determine the turbidity.
a. A centrifuge is a tool used to separate components of a mixture based on their densities, not to measure
turbidity.
c. A microdensitometer is a tool used to measure the optical density of an image, not to measure turbidity.
d. An electrophorometer is a tool used to separate charged particles based on their size and charge, not to measure turbidity.
