From since I remember I have always wanted to be a creative and I have been professionally now for the past 15 years. I've worked in a fair few capacities including freelance, a publishing house, in-house and agency capacity. I create thought provoking materials in a variety of mediums including Print media and Website design, I've been fortunate enough to work with some great brands and people, which have developed my skills to allow me to approach briefs in a nimble, flexible and strategic way.
This document provides guidance for nurses calling doctors with patient issues. It advises nurses to gather relevant patient information, such as charts, vitals, medications and test results before calling. It also recommends nurses identify the problem, their assessment and recommended next steps. Nurses should call the appropriate doctor and cluster calls when possible to provide all necessary information in a clear and concise manner.
This document discusses nursing documentation and record keeping. It outlines the learning outcomes of understanding best practices in documentation and the Nursing and Midwifery Council's principles of good record keeping. Clinical records are used to provide patient care but also in litigation cases and for root cause analysis of medical incidents. Registered nurses are accountable to regulatory bodies, employers, courts, patients and their families for documentation.

2. Найдем корни квадратного трехчлена в левой части
неравенства с помощью теоремы Виета:
При каких a множество решений неравенства
x2
- ( a2
+ a ) x + a3
≤ 0 содержит не менее пяти
целых чисел? (задача из подборки И. Яковлева)
x1
+ x2
= a 2
+ a
x1
x2
= a 3 Отсюда x1= a2
, x2 = a
Разложим левую часть неравенства на множители:
( x - a2
) ( x – a ) ≤ 0
3. Введём параметрическую плоскость (a;x) - вертикальная
ось x, горизонтальная ось a.
Изобразим на параметрической плоскости (a;x) множество
решений неравенства (x-a2
)(x-a) ≤ 0
Знак неравенства меняется при переходе через нули левой
части, то есть через линии x = a2
и x = a.
Эти линии являются границами областей плоскости
(a;x),
в каждой из которых
точки соответствуют
определённому знаку
левой части неравенства.
a
x
4. Эти линии являются границами областей плоскости
(a;x) , в каждой из которых точки соответствуют
определённому знаку левой части неравенства.
Методом проб определим эти знаки.
Пусть a=3 x=0 , т.е.берём точку (3;0 ) ; получим:
(0-32
)(0-3)>0, значит, в области, где лежит эта
точка, левая часть неравенства положительна:
a
x
(3;0)
5. В самом деле,
a x Знак
неравенства Пояснения
0 2 + (2-0)(2-0)>0
3 0 + (0-9)(0-3) >0
3 4 - (4-9)(4-3) <0
-2 3 - (3-4)(2+3) <0
6. Выделим голубым цветом области,
координаты точек которых удовлетворяют
исходному неравенству:
Заметим, что точки,
на графиках x=a2
и x= a
принадлежат множеству
решений исходного
неравенства.
Теперь варьируя значения
а (двигая слева направо
прямую, параллельную
вертикальной оси) , заметим,
что множество решений
исходного
неравенства содержит не
менее пяти целых
значений x при a ≤ -√3или при a ≥ √7
8. Не менее пяти–это значит 5 и более ,т.е. « ≥5 »
По графику смотрим , где целых 5 значений х
(при каком a )?
Ответ: при a = -√3 , а более пяти при a ≤ -√3
В самом деле,
Двигаем далее вправо прямую х= a,
ищем, где количество целых значений х « ≥5 »
по графику смотрим :при a ≥ √7
