Thermometer - The common medical thermometer is always a good tool to have on hand. The new digital thermometers are easier to use and very accurate. Get whichever your budget will allow.

Blood Pressure Equipment - You can now measure your own blood pressure without traditional blood pressure cuff and stethoscope. Handy and accurate blood pressure measuring equipment is available at a decent price. Add a stethoscope to kit anyway, they can still come in handy.

A good supply of over counter medications. Aspirin, cough medicines etc. Don't forget syrup of ipecac. This is used to induce vomiting. Especially useful when you have small children around house.

Other items that don't need narration are scissors, gauze, tweezers, nail clippers, heating pad (for that achy back), eyedropper, and a dental mirror.

You should also keep these on hand. Band-Aids, elastic bandages, butterfly bandages, cotton balls, and safety pins.

If you have children under age of six, you may want to add an aspirator bulb and a rectal thermometer.
