CERTIFIED DIALYSIS NURSE (CDN) – OSCE FINAL SUPPLEMENTARY EXAMINATION
-2026| OBJECTIVE STRUCTURED CLINICAL EXAMINATION (OSCE)
(Dialysis Nursing Competency Assessment – Hemodialysis & Peritoneal Dialysis)
COURSE CODE: CDN 401
COURSE TITLE: Advanced Renal Nursing Practice / Dialysis Therapy
ACADEMIC YEAR: 2025/2026
SEMESTER: II
EXAM TYPE: Practical Clinical Skills Assessment
Functions of kidney include:
A. formation of urine
B. regulation of body water and electrolytes
C. acid-base balance
D. all of the above
D. all of the above
the kidney regulates many hormonal and electrolyte functions. the major functions are:
formation of urine, regulation of body water and electrolytes, acid-base balance, production of
erythropoietin, and production of renin
Renal regulation of homeostasis includes:
A. excretion of metabolic waste
B. promotion of perfusion
C. secretion of anti-diuretic hormone
,D. absorption of vancomycin
A. excretion of metabolic waste
one of the major functions of the kidney is to remove waste products. perfusion is supported by
cardiac function and volume status, secretion of ADH is from the pituitary, and absorption of
vancomycin occurs at the tissue level- vancomycin is cleared via the kidney.
The three processes of urine formation include:
A. glomerular filtration, tubular filtration, and tubular secretion
B. glomerular filteration, tubular reabsorption, and tubular secretion.
C. glomerular filtration, water reabsorption, excretion of sodium
D. glomerular filtration, water secretion,and sodium secretion.
B. The formation of the urine begins with glomerular filtration- then the tubules reabsorb or
secrete electrolytes and particles.
NB: the tubules do not filtrate; sodium is regulated by multiple processes and is not a major
process of the kidney funtion. water reabsorption is a function of tubular reabsorption or
secretion.
The glomerular filtration rate (GFR):
A. equals about 180 L/day
B. equals about 125 mL/ minute
C. Is often calculated by pharmacy and intensivists for drug administration
D. All of the above
D. All of the above
, GFR, a good indication of renal function, equals about 180 L/day or about 125 mL/min, and is a
calculated number by critical care specialists to dose drugs. GFR is excellent measure of current
renal function.
Renal assessment includes:
A. Glomerular filtration rate (GFR)
B. Creatinine
C. Urine output for 24 hours
D. All of the above
D. All of the above
The best measure of current renal function is to measure 24-hour-urine formation, GFR, and
creatinine. These three focus on the kidney's abililty to filter, absorb and secret. This
information is found in the RIFLE study.
Blood-urea-nitrogen (BUN) is a reflection of:
A. Hydration, catabolic state and presence of blood in the gut
B. Hydration, liver function and renal clearance
C. Renal absorption of sodium, total parenteral nutrition (TPN) and disseminated intravasular
coagulation (DIC)
D. Renal excretion of potassium, liver failure and fluid overload
A. Hydration, catabolic state and presence of blood in the gut
- BUN is refection of the intravascular volume status; if intravascularly dehydrated; the BUN will
rise without creatinine elevation.
- If the patient has not had enough protein in their diet- the body will break down muscle to
make protein and that will release nitrogen into the blood, elevating BUN.
- Free blood in the gut (GI bleed) will also break down to protein and elevate the BUN.
