Before we can deliver appropriate nursing care to a complex patient, we need to first acquire the relevant skillset that allows us to identify a patient with complex health care requirements. This includes analysing medical and situational factors that contribute to a complex health care scenario.

Once this has occurred Registered Nurses and other members of the health care team can initiate complex care planning commencing with analysis of the risk of further harm/hospitalisation, identification of the individual’s goals and any barriers to care including conflicting treatment approaches….

## Identify and categorise the salient stakeholders outlined in the case study and justify

For this task you will create a digital poster (900 words, excluding references) on which you outline for the need for change in response to the case study provided. The audience for your poster is the hospital board, manager of the department, and other hospital staff.

You are required to:

Provide a brief summary of the situation Identify the issues within the case study.that will require change. Construct a clear vision and organising statement for this change to motivate and inspire the stakeholders. Identify and analyse forces driving and restraining change by: Using a decision-making theory or model from this course to determine if change is possible. Demonstrate from this analysis how you might strengthen driving forces or weaken restraining forces Identify and categorise the salient stakeholders outlined….

## . For optimum road holding a ‘hard’ suspension is desirable and it is believed that to achieve this the damping should be critical.

During the design of a car, part of the suspension system is tested by subjecting it to violent displacements. One such test is modelled by the differential equation where x is displacement, and initially x = 0 and x = 0. The parameter k ( > 0) is known as the damping coefficient and can be varied during the tests. For optimum road holding a ‘hard’ suspension is desirable and it is believed that to achieve this the damping should be critical. i) Find the value of k for critical damping. ii) Determine x as a function of time t in this case. For a more comfortable ride a ‘soft’ suspension is proposed in which k = 0.6. iii) Determine x as a function of time t for….

## The exponentially decaying terms in the solution describe what is known as the transient current. The non-decaying terms describe the steady state current.

The current in an electrical circuit consisting of an inductor, resistor and capacitor in series with an alternating power source, is described by the equation The exponentially decaying terms in the solution describe what is known as the transient current. The non-decaying terms describe the steady state current. iii) Write down an expression for the steady state current for the solution in part ii). Why would this expression remain unchanged if the initial conditions were different? iv) Express the steady state current in the form R sin (20t + ), where R and are to be determined. Verify that, after only 1 second, the magnitude of the transient current is close to 1% of the steady state amplitude, R.

## Find the dimensions of G. An astronomer proposes a model in which the lifetime, t, of a star depends on a product of powers of its mass, m, its initial radius r0, G and a dimensionless constant. ii) Use the method of dimensions to find the resulting formula for t.

The magnitude of the force of gravitational attraction, F, between two objects of mass m1 and m2 at a distance d apart is given by where G is the universal constant of gravitation. i) Find the dimensions of G. An astronomer proposes a model in which the lifetime, t, of a star depends on a product of powers of its mass, m, its initial radius r0, G and a dimensionless constant. ii) Use the method of dimensions to find the resulting formula for t. Observation shows that the larger the initial radius the longer the lifetime of the star, but that the larger the mass the shorter the lifetime of the star. iii) Is the model consistent with these observations? iv) Show that the model can be expressed more simply….

## In the early seventeenth century Mersenne (1588–1648) conducted experiments with long lengths of rope and so obtained the law for the frequency of transverse vibrations of strings.

In the early seventeenth century Mersenne (1588–1648) conducted experiments with long lengths of rope and so obtained the law for the frequency of transverse vibrations of strings. Assuming that the frequency depends on products of powers of T, the tension in the rope, l, the length of the rope, and m, the mass per unit length of the rope, i) find, by dimensional analysis, the form of the relationship. A rope of length 24 m and mass 0.5 kg m-1 under tension of 72 N is found to vibrate with a frequency of of a cycle per second. ii) State the exact relationship between the frequency, T, l and m. iii) Find the frequency of vibration of a string of length 20 cm and mass 0.005 g cm-1 under a tension….

## Suppose a straight tube could be drilled right through the Earth, modelled as a uniform sphere of radius R and total mass M. A ball of unit mass is dropped into the tube at the surface of the Earth.

A body of unit mass inside a uniform sphere at a distance r from its centre O experiences a gravitational attraction towards the centre ofwhere G is the gravitational constant and Mr is the mass of material inside the sphere of radius r. (In other words it is as if the body were on the surface of a sphere of radius r, all the matter further from the centre than r will have no net gravitational effect on the body.) Suppose a straight tube could be drilled right through the Earth, modelled as a uniform sphere of radius R and total mass M. A ball of unit mass is dropped into the tube at the surface of the Earth. i) Work out the mass of a sphere of the….

## A potter is throwing clay on a wheel which turns at a constant rate

A potter is throwing clay on a wheel which turns at a constant rate. It starts as a solid cylinder of radius r and height h and gradually changes into a jar with the cross-section shown in the diagram. Assume the mass, M kg, and the density of the clay are constant. i) Find an expression for the density of the clay. ii) Find the height, in terms of h, of the jar when the thickness of the base is 0.2h and the inside radius is 0.9r. iii) Assuming the jar is a solid cylinder with another removed from the inside, find its moment of inertia about its axis of rotation in terms of M and r. iv) Find the ratio of the kinetic energy of the jar….

## Two gear wheels are such that, when they are engaged, their angular speeds are inversely proportional to their radii.

Two gear wheels are such that, when they are engaged, their angular speeds are inversely proportional to their radii. One has a radius a and moment of inertia pa2 about its axis of rotation. The other gear wheel has radius b and moment of inertia qb2 . The first is rotating with angular speed  when it engages with the second which is initially at rest. i) By considering the change in angular momentum of each wheel separately, find the impulse between the teeth of the gear wheels when they engage. ii) Find the angular speed of each wheel. iii) Why is the angular momentum not conserved? iv) Find the energy lost when the gears engage.

## This question describes a simplified model of a device used to de-spin a satellite.

This question describes a simplified model of a device used to de-spin a satellite. A uniform circular disc of mass 12m and radius a lies on a smooth horizontal table and is free to rotate about a fixed vertical axis through its centre. A light wire is attached to a point on the rim of the disc and is wound round this rim. A particle of mass m is attached to the free end of the wire and is initially attached to the rim. When the disc is rotating with angular speed in the opposite sense to that in which the wire is wound the particle is released so that the wire unwinds and remains taut. The length of the wire is chosen so that it is completely….
