Article: In general, caulking is a fairly cheap and easy home improvement project. However, it has its limitations. Caulk is useful for sealing small, thin gaps between baseboards and the floor or wall. It's not, however, appropriate for protecting the baseboard itself, which must be painted to provide protection from water damage and wear and tear. Additionally, while baseboard caulking is great for making the bottom edges of a room water-tight, it provides little protection against large sources of water damage, like burst pipes, leaky ceilings or walls, and so on. Thus, baseboard caulking is best used as just one part of a more extensive plan for water-proofing a room which should also include painting, finishing, tiling, and more.  It's also worth noting that baseboards should not be caulked when the floor or wall is unfinished wood. In this situation, caulk provides little protection from water and cannot form a tight seal against the surface it is applied to. The time that it will take to caulk varies based on the size of your project as well as how long it takes you to become familiar with your tools. Most one-room jobs can be completed within an hour or two, while longer jobs can take days. Regardless of the size of your job, you won't want to rush, so leave yourself more time than you think you'll need. A thorough caulking job can take lots of time in the short term, but mistakes in your caulking that can result from rushing can cost you more time in the long run. Generally, caulking is quite cheap. Caulking guns retail from about $5-$10 for cheap options up to about $20 for the highest-quality options. Cartridges of caulk usually cost no more than $5. In addition to these things, you may need to buy masking tape, a knife or scissors, and gloves. All in all, you usually won't need to spend more than $30-$40. If you own some of these materials already, your costs will be lower.  Your costs will vary based on how many cartridges of caulk you need to buy. As a point of reference, for a 10 x 10 foot bathroom, you'll need about 1 or 2 cartridges. It's usually smart to buy a little more caulk than you think you'll need — you can always save this left-over caulk for later.

Problem: Article: Long flights can be very, very boring. You will want to have plenty of ways to entertain yourself. Bring along a book you’ve been wanting to read, pack music to listen to (through headphones), or pack a tablet or laptop computer to watch movies on.  Many long-haul flights also offer in-flight movies, which is great, but you shouldn’t count on this as it may not always be the case. Have a back up plan. Try to get a bit of sleep. For many, sleeping on an airplane is next to impossible, but if you can, try to get a few hours of sleep. This will pass the time, and help you get a little bit of rest before you reach your destination. If you are on a long-haul flight (e.g. a flight overseas) or one where you will fly through the night, recline your seat a bit. While many consider this to be rude behavior, you will find that most people do recline their seat on long flights. However, try to be courteous when doing so, only recline as far back as you need to get comfortable, and glance behind you to see who is sitting there before doing so. If someone that is very tall is already scrunched into the seat behind you, don’t recline the seat and make it even more uncomfortable for them. Even if you are not planning to sleep, bringing along a travel pillow can help make you a bit more comfortable on a long flight. If you don’t use it to rest your head, you can place it behind your back or even sit on it to provide a bit more support. While you will likely be offered food on your flight, this food is usually not very tasty or healthy. Oranges, bananas, watermelon, and whole wheat bread are all reported to be helpful for people suffering from menstrual symptoms. Cut up the watermelon and put it in a sealable plastic container, or just throw an orange or banana in your bag. Not only are these foods healthier, they will help soothe your discomfort. Don’t forget to pack yourself a treat. Part of getting through a painful period is allowing yourself a treat. In this case, you might consider packing a bit of your favorite candy or chocolate to eat while you’re on the plane. Tea and coffee are also believed to be useful for menstruating women. Fortunately, many airlines will offer these complimentary, so enjoy a warm cup of tea or coffee to get some relief. There are several products on the market that aim to provide heat to relax muscles. These wraps work like traditional heating pads in that you apply them to the affected area, but they don’t require electricity or hot water to work. There are even wraps that are designed specifically to help with menstrual cramps.  These wraps can usually be worn underneath your clothes, so you can put one on your lower abdomen (or wherever you are experiencing muscle pain from your period) before you get to the airport. You could also apply one when you go to use the airplane bathroom. Cramps are caused by muscle contractions, and heat works to help the muscles relax a bit.
Summary: Distract yourself. Recline the seat. Bring along a travel pillow. Pack snacks. Drink tea or coffee. Use a heat wrap.

Use your stethoscope in a quiet place. Find a quiet area to ensure that the body sounds you want to hear will not be overpowered by background noises. To listen to the heart and abdomen, you will want to have your patient get into a supine position. To listen to the lungs, you will want your patient to sit up. In other words, ask your patient to lay down. Heart, lung, and bowel sounds may sound different depending on the patient's position: i.e., sitting, standing, lying on one's side, etc.. The diaphragm, or flat side of the drum, is better for hearing medium- or high-pitched sounds. The bell, or round side of the drum, is better for hearing low-pitched sounds. If you want a stethoscope with really high sound quality, you might want to consider an electronic stethoscope. An electronic stethoscope provides amplification so that it is easier to hear heart and lung sounds. Using an electronic stethoscope may make it easier to hear your patient’s heart and lungs, but keep in mind that they are expensive. Use the stethoscope on bare skin to avoid picking up the sound of rustling fabric. If your patient is a man with chest hair, keep the stethoscope still to avoid any rustling sounds. To make your patient more comfortable, warm up the stethoscope by rubbing it on your sleeve, or consider buying a stethoscope warmer.

Select a quiet place to use your stethoscope. Position your patient. Decide whether to use the diaphragm or bell. Have your patient put on a hospital gown or lift up clothing to expose skin.
