Meet a Nurse Practitioner

Dr. Universe, a grey cat with a lab coat, looking through binoculars

Welcome back, young scientists. I’m Dr. Universe.  If you’re anything like me, you’ve got lots of big questions about our world.

Today we’re talking to nurse practitioner Bevan Briggs.

Warning! This episode very briefly mentions intestines, body fluids, shots, stitches, broken bones, surgery, kids putting on pretend wounds (with intestines!) to help EMTs train, and the fact animals are butchered for food in some homes. If that doesn’t sound like something you’d like to hear, I’ll catch you on the next one. If you’re not sure, ask your grownup to preview the audio or transcript. =^..^=

  • Learn what a nurse practitioner does
  • Hear about seeing surgery for the first time and wearing pretend wounds to help train EMTs on ambulances when he was a kid
  • Discover what nursing school and nurse practitioner school are like

  • Why do people like cute animals more than ugly ones?

    Dear Brayden,

    Not to brag, but when I was a kitten, humans would see me and squee. Maybe it was my big, sparkly eyes or my teeny, fluffy paws.

    I asked my friend Giuseppe Giannotti why people found me so adorable. He’s a scientist at Washington State University. He studies the brain.

    He told me that humans like cute animals because they remind them of babies.

    “We’re drawn to find traits in animals that are similar to what we think is cute in humans,” Giannotti said. “The cutest things in humans are babies—you know, big heads, giant eyes, soft cheeks—and we project this to … » More …

  • Why do birds sing in the morning?

    Dear Alexandria,

    I usually write answers to kids’ science questions early in the morning. I like how it’s so quiet—except for my bird neighbors singing and singing.

    I asked my friend Jennifer Phillips what’s going on. She’s a bird scientist at Washington State University.

    She told me birds sing in the morning to tell other birds that their territory still belongs to them.

    “The morning time is usually a little bit more calm, especially in windy areas,” Phillips said. “So, it’s a good time to broadcast your song and for that song to potentially travel a little farther.”

  • Why do we need to hydrate?

    Dear Victor,

    Is there anything better than lapping up cool water on a hot day?

    I talked about why we need to hydrate with my friend Ed Johnson. He teaches classes about the human body in the School of Biological Sciences at Washington State University.

    It turns out that up to 60% of an adult human’s body is water. A kid’s body contains even more water than a grown up. When you were a baby, you were about 78% water.

    Humans use that water for all kinds of things. It keeps you cool when you sweat. It removes waste when you pee. It moves … » More …

  • How does your voice make sound?

    Dear Bianca,

    Think about all the ways you use your voice: talking, singing, whispering, shouting, yodeling. Humans make so many sounds with just their voices.

    I talked about how it works with Alisa Toy. She’s a professional singer who teaches in the School of Music at Washington State University.

    She told me that the human voice is the smallest instrument in the world. The parts that make the sound—called the vocal folds or vocal cords—are about as long as your thumbnail.

    So, where are those tiny vocal folds and how do they do it?

    Inside your throat you have two tubes. The esophagus … » More …

  • What safety measures can we take during extreme weather conditions?

    Dear Zadok,

    When I was a kitten, a tornado tore through the neighborhood I was visiting. It got eerily quiet outside. Then the sky turned green. My littermates and I climbed into an empty bathtub to stay safe. After that, it got super loud.

    I talked about extreme weather with Nathan Santo Domingo. He’s a weather scientist at Washington State University.

    He told me that how to prepare depends on where you live. Different places have different kinds of extreme weather.

    “Keep an eye on the forecast and know what’s coming your way,” Santo Domingo said. “Be smart about what happens in your area.”

  • What is the most dangerous insect in the world?

    Dear Juan Simon,

    The deadliest animal on Earth isn’t a shark or a bear. It’s an insect. Mosquitoes kill way more people than any other animal.

    I talked about it with Jeb Owen. He’s an insect scientist at Washington State University.

    He told me mosquitoes are dangerous because of the way they sometimes eat.

    “Through blood feeding, mosquitoes can transmit pathogens that make people and animals sick,” Owen said.

  • Why do we have nose hairs?

    Dear James and Zion,

    Despite being a curious science cat, I must confess I haven’t spent much time looking up human noses. But I have noticed that human nostrils can be a bit…furry.

    I talked about what’s inside your nose with my friend Edward Johnson. He teaches classes about the human body in the School of Biological Sciences at Washington State University.

    He told me that nose hairs only grow in your nose’s vestibule. That’s the inside of the part of your nostrils that you can flare out. The nose hair’s job is to filter the air you breathe in through your nose.

  • Why do we need the sun?

    Dear Samai ,

    Right now, the sun is shining through my window. It feels warm on my muzzle.

    I talked about the sun with Guy Worthey. He’s a professor of astronomy and physics at Washington State University.

    He told me that our lives depend on the sun.

    “The sun keeps you warm and powers everything,” Worthey said. “Without it, Earth would be a frozen nightmare.”

  • Why do we change our minds?

    Dear Stella,

    As a science cat, I’ve changed my mind a lot over the years. I used to wear a fancy neck scarf called a cravat all the time. Now I’m comfy in my lab coat.

    I talked about that with my friend Makita White. She’s a graduate student in the psychology department at Washington State University.

    She told me that we change our minds when we get new information or insight that tells us we need to make a different choice.

    It turns out that we have lots of opinions and beliefs. They’re also called attitudes. We have attitudes about what we … » More …

  • Why are some veggies called fruits because of their seeds?

    Dear Valerie,

    Every summer I grow peppers in my garden. I always thought they were vegetables. But you’re right that my peppers have gobs of seeds like fruits do.

    To figure out what’s going on, I talked with my friend Jacob Blauer. He’s a plant scientist at Washington State University.

    He told me that whether something is a vegetable or fruit depends on what part of the plant it comes from.

    “Plant products that come from plant parts like roots, leaves or stems are veggies,” Blauer said. “If they come from a flower and bear seeds, they’re a fruit in botanical and scientific terms.”
