NEPHROLOGY SERVICE
STUDENT PACK
This pack contains learning objectives for student nurses whilst on placement
within the nephrology service. These learning objectives should be utilised as a
framework to structure the student’s placement within the nephrology service and
should be used in conjunction with the student’s own personal objectives.
The students should receive the support of their mentor within all three areas of
the service:
Haemodialyis Unit: 3 days.
Peritoneal Dialysis Unit: 2 days.
Renal Ward: rest of placement.
General Objectives of Placement within the nephrology service.
For the students to develop an understanding of:




All types of dialysis.
Acute and chronic renal failure.
Care of patients undergoing haemodialysis, peritoneal dialysis and with
acute renal failure in the ward and dialysis setting.
The wider issues surrounding patients with end stage renal failure such as
psychological issues, transplantation and patient education.
Students will not be expected to complete the whole package within their short time
within the nephrology service. They will be expected to highlight areas of interest
and utilise the package to guide their learning.

How to use this package:
The package is designed to be a directed study package which will guide and facilitate
students learning whilst on placement within the department. The package is separated
into 4 sections:
General section.
Care of the patient within the renal ward.
Care of the patient within haemodialysis.
Care of the patient within peritoneal dialysis.
The aim of the package is that while students are in each of the areas they will complete
the relevant section by referring to the references provided and by encouraging the
student to utilise the knowledge and experience of the nurses in that area. Study time will
be provided by each of the areas and should be negotiated with your mentor or the nurse
in charge.
All the references stated within the text are available within the department.
By the end of the placement you should have completed all of your personal and most of
the overall objectives set within this package.

Caring for a patient within the haemodialysis setting
Aim
The aim of this section of the package is for student nurses to gain sufficient knowledge
in order to effectively nurse patients with chronic and acute renal failure, in
haemodialysis.
Objectives
For the student to:

Identify the principles involved in haemodialysis.

Describe how to care for a patient with chronic renal failure on haemodialysis.

Discuss the different types of vascular access and implications of using each.

Discover common drug therapies utilised for patients with chronic renal failure.

Define the terms haemofiltration and haemodiafiltration.
Haemodialysis
Haemodialysis works by utilising a combination of the following:



Diffusion
Ultrafiltration
Convection
Diffusion is where solutes move from a higher concentration in the blood to a lower
concentration in the dialysate fluid. Therefore, diffusion is the process used to remove the
waste products such as urea, creatinine and salts from the blood. Ultrafiltration is used to
remove fluid from a patient whist on haemodialysis. A set amount of fluid is set on the
machine to be removed over dialysis and the machine works out how much needs to be
removed each hour and sets a pressure gradient, pulling off the fluid at a steady rate over
the dialysis time. As this fluid is removed some solutes are dragged across the dialyser
membrane at the same time, this process is called 'solute drag' or convection.
1 What substances are we trying to remove during haemodialysis?
2. What are the two main types of dialysis access?
3. How and where can an arterio-venous fistula be created?
4. How do you check a fistula to ensure it is functioning?
5. Describe the immediate post operative and long term care of a fistula?
6. Can you describe one other type of access used commonly in haemodialysis?
7. What education should patients be given on care of their fistula?
Haemodialysis is the main treatment for patients with chronic renal failure. Two other
methods that you may come across during your time in the haemodialysis unit are
Haemofiltration and Haemodiafiltration.
Haemofiltration is mainly used for patients who are unstable and are unable to tolerate
haemodialysis, such as acutely ill patients.
Haemodiafiltration -used for patients who are cardiovascularly unstable on haemodialysis
and to improve the quality of dialysis.
8. The assessment of patients before going on dialysis consists of:





Blood Pressure.
Weight.
Temperature.
Checking for oedema or breathlessness.
Observation of fistula/centralline exit site
Explain the reason for each of the above and what you would do if any abnormalities
were noted.
9. Patients are monitored hourly on dialysis. Discuss with your mentor what patient and
machine observations are being monitored and why.
10. Post dialysis patients: blood pressure, temperature and weight are recorded again,
why?
11. The following are all emergencies that can occur on dialysis:
}> Hypotension
}> Cramp.
}> Cardiac arrest.
}> Respiratory arrest.
}> Air embolus.
}> Dialyser reactions.
}> Clotted dialyser/lines.
Discuss with your mentor how and why these occur and preventative or reactive action
required if they do.
While dialysing an acutely ill patient the same observations would be monitored although
the frequency of monitoring would be increased to ~ hourly and the patient would be
placed on a cardiac monitor and nursed either on a one to one basis or with a higher
nurse/patient ratio.
Common drug therapies utilised in patients with chronic renal failure.
Patients with chronic renal failure can be on a large number of drugs the most common
being:
);> Vitamins e.g. Renavit &Vitamin D.
);> Phosphate binders e.g. Calcichew & Renagel.
);> Blood pressure medication e.g. Atenolol & Doxazosin.
);> Anticoagulants -during dialysis and at home e.g. Heparin & Warfarin.
);> Antibiotics -I.V. & oral. );> Hormones e.g. Epo. );> Iron e.g. Venofer.
Briefly describe why patients would require this medication.
What special instructions or precautions would require to be taken in relation to initiating
dialysis and administration of these drugs whilst patients are undergoing dialysis?

Care of a patient within the peritoneal dialysis setting
Peritoneal dialysis is a dialysis option that utilises the peritoneum as the filter to excrete
waste products from patients.
Aim
The aim of this section is for the student nurse to have a basic knowledge of peritoneal
dialysis, how it works and what is involved in the treatment.
Objectives
For the student to:

Identify the principles of peritoneal dialysis.

Describe the care of a patient with chronic renal failure on peritoneal dialysis.

Discuss how access is achieved to the peritoneum and how dialysis is initiated.

Identify the complications of peritoneal dialysis.

Identify the different forms of peritoneal dialysis.
Questions
1. Where is the peritoneum?
2. Peritoneal dialysis works by
~ Osmosis.
~ Diffusion.
~ Convection.
Discuss these three transport principals in relation to peritoneal dialysis.
Access for peritoneal dialysis is obtained via a tenckhoff catheter, which is inserted by
the surgeons, into the peritoneal cavity. Post operatively the catheter is completely
covered and immobilised against the skin to promote healing and help prevent infection.
The catheter is left for 7-10 days or until the exit site is completely healed, e.g. no
discharge I signs of infection before dialysis is commenced. The patient is then trained to
perform their dialysis and once they are competent are discharged home and reviewed at
regular intervals by multidisciplinary renal team.
3. What is the care of the Tenckhoff catheter exit site?
4. What can happen if the exit site becomes infected and is not treated?
5. Describe the difference between Continuous Ambulatory Peritoneal Dialysis (CAPD)
and Automated Peritoneal Dialysis (APD).
6. Why would patients need different strengths of peritoneal dialysis fluid?
The most common complication of peritoneal dialysis is peritonitis this is an infection of
the peritoneal membrane. Presenting signs and symptoms of peritonitis can differ from
patient to patient with the most common symptoms being:
~ Cloudy PD fluid
~ Nausea I vomiting
~ Crampy stomach pains I back pain
~ Flu like symptoms
Early diagnosis and treatment of peritonitis it is important to minimise the risk of
developing septicaemia and damaging the peritoneal membrane.
7. What are the common causes of peritonitis and how can they be prevented?
8. What happens to the peritoneum long term with peritonitis?
9. What happens if peritonitis does not clear or the patient has recurrent episodes?
10. What are the other common problems associated with peritoneal dialysis?
