Article: To keep your vehicle moving smoothly, be sure to slow down well ahead of any speed bumps, turns, or stoplights that you approach. Engage the clutch to put the gear shift into the neutral position if you need to slow down to the point where you need to put the engine in a lower gear. Pay attention to road signs that will tell you when a speed bump or turn is coming up. If you're in traffic that's traveling at speeds up to about 10 miles (16km) per hour, keep the engine in first gear so you can move forward steadily. The vehicle won't move forward if it's in the neutral gear. Shift the vehicle into second gear when the traffic gets up to about 15 miles (24km) per hour. Be sure to keep at least 1 car length in front of you in case you need to stop suddenly. If you're moving too slow in 1st gear, the engine could stall. Engage the clutch, shift the gear shift into neutral, and release the clutch to keep the engine in neutral. Let the vehicle roll and use your breaks to slow it down or stop if you need to. Don't put the engine into the neutral gear then coast while using your breaks to slow down or you could cause the vehicle to jerk or the gears to grind. Instead, shift back down through the successive gears until you're in the gear that's best suited to maintain the speed that traffic is moving in. Don't skip gears. For instance, don't shift from 4th gear straight to 2nd or it can cause the gears to grind and the vehicle to shake uncomfortably.
Question: What is a summary of what this article is about?
Slow down ahead of speed bumps and turns. Keep the vehicle in 1st gear in slow-moving traffic. Put the gear shift in the neutral position when traffic stops or slows to a crawl. Downshift while using the breaks to slow down from a higher gear.

Problem: Article: Do a complete history and physical exam and review your patient's vaccination history before administering the vaccine. Ask if your patient is taking any medications, has any allergies, or has ever reacted to a vaccine previously. Do not give it if they have ever had a severe allergic reaction (anaphylaxis) to a component of the vaccine or to the antibiotic neomycin. Pregnancy is a contraindication to giving the MMR vaccine do not give pregnant women this injection. If your female patient is unsure whether she is pregnant, do a urine test to ensure she is not before administering the vaccine. Let her know this is for her and her baby's safety. Wait until after the baby is born to give the vaccine. Advise women not to get pregnant for 4 weeks after getting the vaccine. Severe immunocompromise is a contraindication to the MMR vaccine. Take a thorough medical history of your patient. Do not give them MMR if they suffer from poor immunity due to any of the following: HIV with severe immunocompromise (having the virus alone is not a contraindication if they are in generally good health) Any type of cancer or cancer treatment Current chemotherapy or radiation therapy Congenital immunodeficiency Low platelet count Received another vaccine in the past four weeks Received a recent blood transfusion Long-term immunosuppressive therapy, such as with corticosteroids Some circumstances are not contraindications to the vaccine, but may make it more likely the patient will have an adverse reaction or the vaccine may not work properly. Don't give the vaccine if any of these conditions are present, unless the benefit outweighs the risk. Use your best clinical judgment! Consider deferring the MMR vaccine if: The patient received antibody-containing blood products in the last 11 months The patient has a history of thrombocytopenia or thrombocytopenia purpura The patient will need TB testing or interferon-gamma release assay (IGRA) testing within the next few days; do not give the vaccine if you suspect active TB is present The patient is moderately to severely ill (mild acute illness is usually not a problem)
Summary: Screen for a history of allergic reaction. Do NOT give MMR to a pregnant woman. Avoid the MMR vaccine in immunocompromised patients. Determine if circumstances necessitate waiting on or avoiding certain vaccines.

You'll need to start by assembling a list of the numbers for which you'd like to find the weighted average. For example, if you're trying to find a weighted average for a series of grades in a class, first write down each of the grades. For instance, maybe your total grades are 82 for quizzes, 90 on your exam, and 76 on your term paper. Once you have your numbers, you'll need to know how much each of them weighs, or is worth, as part of your final average. For instance, in your class, the quizzes might be worth 20% of your total grade, while the exam is 35% and the term paper is 45%. In this case, the weights add up to 1 (or 100%). In order to use these percentages in your calculation, you'll need to convert them to decimal form. The resulting numbers are called "weighting factors." Once you have all your numbers, pair up each number (x) with its corresponding weighting factor (w). You'll be multiplying each set of numbers and weights together, then adding them all up to find the average. For example, if your total quiz score is 82 and quizzes are worth 20% of your grade, multiply 82 x 0.2. In this case, x=82 and w=0.2. The basic formula for a weighted average where the weights add up to 1 is x1(w1) + x2(w2) + x3(w3), and so on, where x is each number in your set and w is the corresponding weighting factor. To find your weighted average, simply multiply each number by its weight factor and then sum the resulting numbers up. For example: The weighted average for your quiz grades, exam, and term paper would be as follows: 82(0.2) + 90(0.35) + 76(0.45) = 16.4 + 31.5 + 34.2 = 82.1. This means you have a grade of 82.1% in the course.
