Python has two built-in functions that work with inheritance: 1  Use isinstance() to check an instanceâs type: isinstance(obj, int) will be True only if obj.__class__ is int or some class derived from int. 2  Use issubclass() to check class inheritance: issubclass(bool, int) is True since bool is a subclass of int.
Measurement â  Begin routine blood pressure (BP) measurement at 3 years of age. â  Correct cuff size depends on arm size. Practically speaking,correct cuff size equals largest cuff that will fit on the upper arm with room below for the stethoscope head. â  BP should be measured in the right arm of a relaxed,seated child.
A cuff that is too small will cause a falsely high blood pressure. A cuff that is too big will cause a falsely low blood pressure. Do not take a BP reading in an arm that is injured or has an IV or shunt. Do not check your blood pressure within 30 minutes of smoking, drinking coffee, or exercising. These may affect your BP reading. Rest quietly for 5 minutes before you take your BP.
