  NCLEX • MOH • DHA • HAAD • Prometric • Nursing Competitive Exam One-Page Study Notes Think: “Right fluid + right place + right amount = normal body function.” I. FLUID & ELECTROLYTE BALANCE — HIGH-YIELD REVIEW What Are Electrolytes? Electrolytes are substances that dissolve in body fluids and separate into electrically charged particles (ions) . Examples: Sodium (Na⁺) → positive ion (cation) Potassium (K⁺) → positive ion Chloride (Cl⁻) → negative ion (anion) Bicarbonate (HCO₃⁻) → negative ion NCLEX Memory: CATions are PAWsitive (+) (Calcium, Potassium, Sodium = positive) Measurement of Fluids & Electrolytes Fluid Volume Measured in: Liters (L) Milliliters (mL) Examples: 1 L = 1000 mL IV fluids commonly measured in mL/hr Electrolyte Measurement Measured in: Milliequivalents (mEq) Meaning: Reflects the chemical combining power of electrolytes. Example: 1 mEq cation = combines with 1 mEq anion Exam Pearl: mEq tells h...

Think: “Musty smell + fair child + developmental delay = check for PKU.” What is Phenylketonuria (PKU)? Phenylketonuria (PKU) is a rare inherited metabolic disorder where the body cannot properly break down phenylalanine , an amino acid found in protein foods. Normally: Phenylalanine → (Phenylalanine Hydroxylase + BH4) → Tyrosine In PKU: The enzyme phenylalanine hydroxylase (PAH) is deficient Phenylalanine builds up in the blood Excess phenylalanine becomes toxic to the brain Tyrosine levels decrease → reduced melanin production NCLEX Keyword: Autosomal recessive disorder Why Does PKU Matter? Without early treatment, elevated phenylalanine can cause: 🧠 Permanent neurological damage 🧠 Developmental delay 🧠 Intellectual disability 🧠 Seizures This is why newborn screening is critical. Pathophysiology in One Minute Protein intake ↓ Phenylalanine cannot convert to tyrosine ↓ ↑ Phenylalanine accumulation ↓ Brain toxicity + ↓ melanin ↓ Neurological s...

The NCLEX Nurse’s Guide to Recognising and Managing Neurological Emergencies Preparing for the NCLEX-RN® means learning more than facts—you must think like a nurse, prioritise patient safety, and recognise early signs of deterioration. One topic that repeatedly appears in NCLEX neurological questions is Increased Intracranial Pressure (ICP) . This is a priority condition because delayed recognition can lead to brain herniation, permanent neurological damage, or death . In this blog, you’ll learn the essentials in an NCLEX-style format: assessment, priorities, interventions, and common exam traps. What Is Increased Intracranial Pressure (ICP)? Intracranial pressure (ICP) is the pressure inside the skull produced by: Brain tissue Cerebral blood volume Cerebrospinal fluid (CSF) Since the skull cannot expand, any increase in volume raises pressure and affects brain perfusion. Normal ICP: ✅ 5–15 mmHg Concerning elevation: ⚠️ Sustained ICP above approximately 20–22 mmHg often requires int...

  Renal Transplantation Surgery Paragraph 1 Renal transplantation is a life-saving specialty that offers both technical and intellectual challenges. In the United Kingdom, transplant centres perform thousands of kidney transplants each year. Because many patients remain on waiting lists for long periods, there is a continuing need for more transplant surgeons and more donor organs. Paragraph 2 Several developments aim to increase the availability of donor kidneys. These include xenotransplantation (using animal organs), non-heart-beating donors, and living related donor transplantation. Advances in immunosuppressive drugs and genetic engineering have made xenotransplantation more realistic, although it remains largely experimental. Paragraph 3 Living related kidney donation has become increasingly common. The introduction of laparoscopic donor nephrectomy allows surgeons to remove a donor kidney through small incisions. Compared with open surgery, this technique may reduce p...
