Describe how chemistry can be used to evaluate an environmental or societal issue or problem. For full credit, answer each of the following parts. It is helpful if you label each part with the associated letter when answering. a) State the issue or problem you’ll be discussing. (1 pt) b) Explain why the item you chose is an issue or problem for society or the environment. (1 pt) c) Explain how one chemistry concept we have studied this semester relates to the issue or problem you have chosen. Clearly state the concept and where it shows up in the problem you are discussing for full credit. (2 pts) d) Explain how understanding the chemistry concept helps to better understand and/or help solve this particular problem or issue. Include at least one way the chemistry concept explains a part of the larger problem. (2 pts) Here are some possible categories of topics, however, you may select any topic: -Plastics and pollution -Nutrition -Climate Change -Consumer Products  -Medicine and health care -Radiation or nuclear energy

When using an SVN or pMDI with NIV, where in the NIV circuit should the device be placed to obtain the greatest aerosol deposition?

The hemodynamic values for a patient in the cardiovascular care unit are: blood pressure (BP) 96/60 mm Hg, pulmonary artery pressure (PAP) 29 mm Hg, pulmonary capillary wedge pressure (PCWP) 14 mm Hg, stroke volume (SV) 50 mL. The patient has a body surface area of 1.6 m2. Calculate the patient’s left ventricular stroke work (LVSW).

Based on the Scenario above,   What would be the most effective means of reducing the patient’s PaCO2? 

Based on the scenario above What is the problem, and what would you suggest to correct this problem and still help the patient?

A patient diagnosed with sepsis who is being mechanically ventilated has a combined minute ventilation of 25 L/min with a PaCO2 of 38 mm Hg. The reason for these findings is most likely which of the following?1. Increased CO22. Decreased CO23. Increased VD/VT4. Decreased VD/VT

Advantages of closed suctioning include which of the following?1. No need to prehyperoxygenate or posthyperoxygenate2. No need to prehyperventilate or posthyperventilate3. Decreased risk for infection for caregiver4. No loss of PEEP during the procedure

A male patient (74-kg IBW) is being ventilated with PC-CMV, f = 12/min, PIP = 20 cm H2O, TI = 1.5 s; the resulting flow–time scalar is shown below. The patient’s measured VT is 435 mL. ABG results on these settings are: pH 7.32, PaCO2 54 mm Hg, HCO 25 mEq/L. The most appropriate action to take is which of the following?

Which of the following can cause metabolic alkalosis?

Geometry ‘Reasons’ – 2024    Given    Def of congruency  Def of complementary/supplementary angles  Def of linear pair  Def of vertical angles  Def of midpoint  Def of angle/segment bisector –   Def of median – from vertex to midpoint of opposite side  Def of perpendicular lines – allows us to say the angles formed is 90 degrees  Def of right angle – we can say the measure of the angle is 90 degrees  Def of altitude    Reflexive Property  Transitive/Substitution Property    +/-/*/division Property of equality    Angle addition postulate  Segment addition postulate  SAS/SSS/ASA/AAS/HL postulates  CPCTC    Linear Pair Theorem  Vertical Angles Theorem  Pythagorean Theorem  Congruent Supplement/Complement Theorem      And some bonus tips:  Each statement requires a reason  Congruence is a relationship between objects, equality is a relationship between numbers (like measures of angles or lengths of segments)  Equality should be used if adding values  Givens should be at the beginning… arrows do not go into Given bubbles  Arrows show how statements are derived using other previous statements  Repeated redundancy : if we use arithmetic properties, we have to show the things being added/subtracted/etc are equal before using them  Try working backwards from the ‘Prove’ statement to see if there is another statement that you can work towards
