Essential Clinical Diagnostic & Care Guides

1. Blood Sugar Profile

Tests: Includes Fasting (FBS), Postprandial (PPBS), Random (RBS), HbA1c (3-month average), and Oral Glucose Tolerance (OGTT).

Key Symptoms: Highlights the "3 Ps" of high blood sugar: Polyuria (frequent urination), Polydipsia (thirst), and Polyphagia (hunger).

Importance: Used to diagnose and monitor Diabetes Mellitus and prevent long-term damage to kidneys, eyes, and nerves.

2. Liver Function Test (LFT)

Markers: Evaluates Bilirubin (excretory), ALT/AST (cell injury), ALP/GGT (bile flow), and Albumin/PT/INR (liver's protein-making ability).

Patterns: Distinguishes between Hepatocellular Injury (e.g., Hepatitis) and Cholestatic Patterns (e.g., bile duct obstruction).

Mnemonic: Uses "BLAAGP" to remember the main components.

3. Anesthesia Fundamentals

Types: Covers General (unconscious), Regional (large area), Local (small area), and Sedation.

Stages: Details Guedel’s Stages of anesthesia, from Analgesia to the life-threatening Medullary Paralysis.

Safety: Includes the ASA Classification to assess patient health risks before surgery and lists immediate vs. serious complications like malignant hyperthermia.

4. Enteral Tube Feeding

Indications: Necessary for patients with a functioning gut who cannot eat orally (e.g., stroke, dysphagia, or unconsciousness).

Tube Types: Differentiates between short-term (Nasogastric) and long-term (G-tube/J-tube) access.

Nursing Care: Emphasizes verifying tube placement, elevating the head to 30–45°, and monitoring for complications like aspiration or tube blockage.
