Q: If you're not adding piped decorations but still want to add some flair, use a spatula to create waves in the icing. Swirl the whipped cream frosting to create small waves all over the cake for a more rustic look. For a crisp, uniform layer of frosting that's perfect for layering piped designs, run a bench scraper all around your cake. Start by working the bench scraper in a circle around the edges, before running it along the top. Pull the bench scraper towards you, and remove any excess frosting that collects on the blade. Once you've spread an even layer of frosting onto your cake, remove your icing bag from the fridge, and add some piped designs. Pipe around the edges of the cake to make a border, and pipe along the top to create flowers or pretty dollops. Practice piping a few designs on wax paper before icing directly onto the cake. Before serving, allow your cake to set in the fridge for at least 30 minutes so that your decorations will hold their shape. The icing will maintain its shape for 2-3 days if left in the fridge, and for several hours if left at room temperature. If you leave whipped cream frosting at room temperature for longer than 3-4 hours, it may become destabilized. It will lose its fluffy, frosting shape, and it might melt off your cake.
A: Create a rustic look by making waves in the icing. Use a bench scraper to level the cake before piping decorations. Add piped decorations to your cake. Place the decorated cake in the refrigerator.

Q: Click the Apple icon in the upper-left corner of your screen to open the Apple menu. This will open your System Preferences in a new window. This option looks like a keyboard icon on the second row of the System Preferences menu. It will open your typing and input settings. You can find it next to Text on the Keyboard page. The Keyboard menu may automatically open up to this tab. In this case, you don't have to click the tab here. When this option is selected, the Fn key on your keyboard will be disabled except the special functions printed on each of your F keys. You can find this option at the bottom of the Keyboard menu. The F keys on the top row of your keyboard will now act as standard function keys (F1F12). You can use the function keys without pressing Fn. If you want to use one of the special functions printed at the top of your keyboard, hold down Fn while pressing the F key. This will now be the only function of your Fn key.
A: Open your Mac's Apple menu on the menu bar. Click System Preferences on the menu. Click Keyboard in System Preferences. Click the Keyboard tab at the top. Check the "Use F1, F2, etc keys as standard function keys" box.

Q: Insert the lubricated end of the tube into the clearest nostril, aiming the end of the tube straight back as you feed it in. The patient must continue looking straight at you. Direct the tube down and toward the ear on that side of the head. Do not allow the tube to feed upward and into the brain. Stop if you feel resistance. Pull the tube out and try the other nostril. Never force the tube inward. If you have coated the patient's throat with anesthetic throat spray, ask the patient to open his or her mouth and watch for the other end of the tube. For patients who were not treated with throat spray, opening the mouth might be too painful. Instead, you should simply ask the patient to indicate when he or she feels the tube at the back of the throat. As soon as the tube hits the top of the throat, guide the patient's head so that the chin touches the chest. This can help encourage the tube into the esophagus, rather than into the trachea. Give the patient a glass of water with a straw. Ask him or her to take small sips and swallows as you continue guiding the tube downward. If the patient is unable to drink water for any reason, you should still encourage him or her to dry swallow as you feed the tube into the throat. For infants, give the patient a pacifier to encourage him or her to suck and swallow during the process. Continue feeding the tube into the patient's throat until the marked measurement reaches the patient's nostril. If you meet resistance further into the throat, slowly rotate the tube as you advance it. This should help. If the tube still gives considerable resistance, pull it out and try again. Never force it in. Stop immediately and remove the tube if you notice a change in the patient's respiratory status. This can include choking, coughing, or difficulty breathing. A change in respiratory status suggests that the tube has been inserted into the trachea by mistake. You should also remove the tube if it comes out of the patient's mouth.
A: Insert the tube into the chosen nostril. Check the back of the throat. Instruct the patient to swallow. Stop once you reach the measured mark.

Q: Tap the Skype app icon, which resembles a white "S" on a blue background. If you aren't logged into Skype, you'll need to enter your email address (or phone number) and password before continuing. It's a person-shaped icon at the top of the screen. Doing so opens a list of your contacts. This option is at the bottom of the screen. Tapping it prompts a menu to open. It's in the menu. This opens a text box. Doing so searches Skype for your specified contact. Tap the name of a contact whom you want to add. It's a blue button in the middle of the page. This option is below the text box. Doing so sends an invitation for the person to join your contacts; if they accept, you'll see them online, and you'll be able to chat with them as you please. You can first edit the invitation message by typing your preferred message into the text box that appears. If your friend doesn't already have a Skype account, you can invite them to create one and join you on Skype by doing the following: Tap the "Contacts" icon in the bottom-right. Tap Invite People to Skype. Select a contact method (e.g., your text messaging app or Gmail). Enter your friend's contact information (e.g., their phone number or email address). Tap the Send button or icon.
A:
Open Skype. Tap the "Contacts" icon. Tap +. Tap Find people. Enter a name, email address, or phone number. Select a result. Tap Add to contacts. Tap Send. Invite a friend to join Skype.
