About Nurse Muesel....My name is Theresa Muesel and I am so excited to start my second year as the nurse here at Keenan.  I have been a nurse for 13 years. I received my Bachelor of Science in Nursing from the University of the Incarnate Word and spent most of my time in the Neonatal ICU as a bedside nurse and educator.  I discovered a passion for teaching during my time in the NICU and earned my Master of Science in Nursing from the University of Texas in Austin.  Health and education are my passions and being able to practice both each day as a school nurse has been a dream!  I am looking forward to a safe and healthy 2019-2020 school year.

Hello Keenan Lion Family,

I hope this note finds you and your family healthy and safe. I sincerely miss seeing my little lions and taking care of them at school. For now as we adjust to this new "norm" I will be sending out an update weekly regarding health and wellness. I will not only try to cover information regarding COVID-19, but also provide some health and wellness education, activities and resources. I have launched my personal website,, which has a tab with reliable resources to consult regarding COVID-19.

Please refer to and your email with district wide updates regarding COVID-19 and its effect on the school district. Here are some friendly health reminders to prevent the spread of the virus:

The best way to prevent illness is to avoid being exposed to this virus. The CDC, as well as government officials, are strongly suggesting that we all practice social distancing. So tempting as it is to go visit friends or hang out with others at parks, we all need to resist the urge and stay home.

If you must go out (to get groceries for example), do your best to maintain 6 feet distance from others. Wash or sanitize your hands immediately after going out in public. Also, it is probably best to leave your student(s) at home as to minimize contact.

There are everyday steps that can also help prevent the spread of all respiratory diseases, including:
· Avoid close contact with people who are sick. If you or someone is sick at your home, stay in a separate room and use a separate bathroom if possible. If not, clean with disinfectant objects and surfaces when touched.
· Avoid touching your eyes, nose, and mouth.
· Stay home when you are sick.
· Cover your cough or sneeze with a tissue, then throw the tissue in the
trash. If a tissue is not available cough into your elbow
· Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
· Wash your hands often with soap and water for at least 20 seconds, 
especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing. The type of soap is not important; it is the motion of washing that cleanses your hands. If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.

While at home here are some general tips to keep your little Lion healthy!

• Try to eat healthy - Eating a healthy and varied diet will give our bodies the best vitamins and nutrients which in turn builds our immune system to fight diseases like COVID-19. Extra Vitamin C is especially good to keep our immune systems strong. Fun fact: the human body cannot produce or store vitamin C so it’s essential to consume it

regularly. Foods high in vitamin C include oranges, lemons, broccoli,

cantaloupe, bell peppers, and strawberries.

  • Try to get 60 minutes of family exercise daily. This can be as simple

    as playing outside in the backyard or going for a walk around your neighborhood. This will get our hearts pumping and give us a boost of endorphins. The 60 minutes does not all have to be together. It
    can even be split up in 10 minute segments.

  • Try to get enough sleep - Make an effort to get 8-10 hours of sleep a

night. Adequate sleep refreshes and regenerates our cells in ways that science is just now beginning to understand. It also helps improve your immune system.

  • Limit screen time - too much screen time is not healthy. I am acutely aware of how challenging this proves to be in this unusual time, especially with three young children of my own. Encourage your little lion to engage in activities throughout the day that does not involve screens such as puzzles, build things with blocks, set up forts, play tag, make an obstacle course, etc. In particular, the 2 hours before bed are crucial to reducing screen time for healthy sleep. Shut off media to help relax and unwind before bed. There is data suggesting that too much "blue light" from screens inhibits melatonin production which reduces the quantity and quality of sleep.

  • Try to maintain a routine - this is easier said than done but children thrive on routine. Since changes in routine can be stressful, it will be helpful to talk with your kids about why they are staying home and what your daily structure will be during this time. Let them help create a daily schedule that can hang on the refrigerator or somewhere they can see it each day. Be sure to include breaks from tele-work or schoolwork to relax and connect with each other. Maintaining some a routine at home will make it easier to regain their schedule when back at school.

At this time social distancing and basic preventive hygiene is key to remaining healthy and slowing the spread.
