AAMI

FDA

IEC

NFPA

Answer 1

Question 216:RR interval-it is an easy way to measure the ventricular rate.that is,the distance between two consecutive R waves and use a standard scale to find the rate.if ,two consecutive R waves are separated by only one large box ,then the rate is 300 beats per minute.if it is divided by two large boxes then ventricular rate is 150 beat per minute.

Question 226: flashRAM :becoz it has high reliability,modular form factors and long life cycles with out BOM change.

Question no 236:microshock is a le value current which passes directly the heart via needle or catheter in an artery or vein.

Question 246:Nothing both are mandatory.code was developed as a guide for carrying out nursing responsibilities in a manner consistent with quality in nursing care and ethical obligations of the profession.standards in nursing are general guidelines that provides a foundation as to how a nurse should act and what she can or cannot do in her profession .Thus,both are mandatory.
