About the Cover
About 5 weeks after breaking his arm, the little mole is at the doctor’s office to see how he’s healing. On the computer screen, you can see an X-ray of the healing bone called the radius. The bone was held in place by a soft fiberglass cast. Notice how a little bump (called a callus) has formed as the bone has healed.
On the doctor’s shelves, you can find:
- milk of magnesia: a liquid medication (activity on page 9) for heartburn, upset stomach, and constipation
- hydrogen peroxide: a chemical disinfectant commonly used for cleaning wounds
- bandages: used to cover cuts and speed up the body’s ability to heal wounds (find out more about bandages on page 4, and how to make your own on page 5)
- pain relief medication (analgesics): treat pains from injuries, twisted ankles, and headaches
- all the cool “Doctor” books: Dr. Grey, Dr. Who, Dr. Sleep, Dr. Strange, and Dr. Dolittle
On the counter, you can also find:
- otoscope: used to check ears for signs of hearing loss, earaches, and infections, or to find out if an ear canal needs cleaning
- sphygmomanometer (or blood pressure cuff): used to measure how well a heart is pumping blood throughout the body
- digital thermometer: tells whether you have fever as your body is busy fighting germs (read more on page 3)
