Expert-defined terms from the Postgraduate Certificate in Renal Care (Part II) course at LearnUNI. Free to read, free to share, paired with a professional course.
Adequacy of Dialysis – related terms #
dialysis prescription, clearance. A measure of whether the dialysis dose meets the patient’s metabolic needs, often expressed as Kt/V or urea reduction ratio. In palliative care, adequacy is balanced against quality‑of‑life goals; a lower dose may be acceptable if it reduces treatment burden.
Advance Care Planning (ACP) – related terms #
living will, directive. A structured process whereby patients, families, and clinicians discuss future health‑care preferences, including decisions about dialysis continuation, transplantation, and end‑of‑life care. Documentation guides clinicians when the patient loses decision‑making capacity.
Alkaline Phosphatase – related terms #
bone turnover, renal osteodystrophy. An enzyme measured in serum that may rise in high‑turnover bone disease, a common complication of chronic kidney disease (CKD). Elevated levels can signal worsening mineral‑bone disorder, influencing symptom management in palliative settings.
Albumin, Serum – related terms #
nutritional status, prognostic marker. Low serum albumin (<3.5 G/dL) reflects malnutrition, inflammation, or fluid overload and is associated with poorer survival. It helps clinicians gauge disease trajectory and tailor comfort‑focused interventions.
Angiotensin‑Converting Enzyme (ACE) Inhibitors – related terms #
blood pressure control, proteinuria. Medications that reduce intraglomerular pressure and slow CKD progression. In advanced disease, they may be deprescribed if they cause hypotension, cough, or interfere with palliative goals.
Arteriovenous Fistula (AVF) – related terms #
vascular access, dialysis. A surgically created connection between an artery and a vein, providing durable access for hemodialysis. In palliative care, the decision to create, maintain, or abandon an AVF involves weighing procedural risk against expected benefit.
