BNS-202 IGNOU Solved Assignment 2026-27

BNS-202 Applied Sciences Solved TMA (Digital PDF)

The Tutor Marked Assignment (TMA) for BNS-202 Applied Sciences is a mandatory 30% weightage component for IGNOU’s B.Sc.N. (PB) program, requiring students to demonstrate mastery of foundational scientific principles in healthcare. Below are verified solutions for key blocks, structured to meet university guidelines for academic integrity and submission deadlines.

Core Syllabus Blocks & Solved Units

• Block-1: Biochemistry
  • Unit 1: Carbohydrates, Lipids, and Proteins

    Solutions include detailed explanations of metabolic pathways (e.g., glycolysis, beta-oxidation) with clinical relevance to diabetes and malnutrition. Example: Q: Explain the role of insulin in glucose metabolism. Answer: Insulin facilitates glucose uptake by cells via GLUT4 receptors, regulating blood sugar levels post-prandially. Deficiency leads to hyperglycemia.

  • Unit 2: Enzymes and Vitamins

    Discusses enzyme kinetics (Michaelis-Menten) and vitamin deficiencies (e.g., scurvy, beriberi) with nursing implications for patient education.

• Block-2: Biophysics
  • Unit 3: Electrophysiology and Medical Imaging

    Covers ECG interpretation (PQRST waves) and X-ray principles, with solved numericals on radiation safety (e.g., Q: Calculate exposure dose for a chest X-ray.).

  • Unit 4: Thermodynamics and Fluid Dynamics

    Explains osmosis in clinical contexts (e.g., IV fluid administration) and heat transfer in wound care.

• Block-3 & Block-4: Microbiology-I & II
  • Unit 5: Bacterial Pathogenesis

    Detailed answers on Staphylococcus aureus (toxin production, MRSA resistance) and Q: Compare Gram-positive vs. Gram-negative cell walls. Includes diagrams of bacterial structures.

  • Unit 6: Viral and Fungal Infections

    Solutions for HIV lifecycle, antifungal mechanisms (e.g., azoles), and nursing interventions for immunocompromised patients.

  • Unit 7: Immunology Basics

    Explain humoral vs. cell-mediated immunity with examples (e.g., antibodies vs. T-cells in transplant rejection).

• Block-5: Nutrition and Dietetics
  • Unit 8: Nutritional Assessment

    Solutions for calculating BMI, RDA for protein in wound healing, and dietary modifications for renal disease (e.g., low-potassium diets).

  • Unit 9: Malnutrition and Enteral Nutrition

    Discusses PEM (Protein-Energy Malnutrition) signs, tube feeding protocols, and Q: Design a 24-hour diet plan for a patient with diabetes.

Key Features of the Solved TMA

• Plagiarism-Free Content: Solutions are 100% original, referencing IGNOU’s prescribed textbooks (Biochemistry for Nurses, Medical Microbiology) and peer-reviewed sources.
• Word Limit Compliance: Strict adherence to 500 words (long answers), 250 words (medium), and 100 words (short) per question.
• Digital PDF Format: Optimized for eGyanKosh submission with clear headings, numbered answers, and visual aids (e.g., metabolic pathways, bacterial diagrams).
• Current Session Updates: Aligned with the 2026-27 academic session curriculum changes (verified via eGyanKosh).

FAQs for BNS-202 TMA

Submit the digital PDF via eGyanKosh under the Assignments section within the student portal. Ensure the filename includes your Enrollment Number (e.g., BNS202_TMA_12345678.pdf).

Yes, but they must be hand-drawn or scanned (not screenshots from online sources) and labeled clearly (e.g., Figure 1: Lactose Digestion Pathway). Avoid copyrighted images.

Deadlines & Submission Guidelines

The TMA for BNS-202 must be submitted within 3 months from the date of enrollment. Late submissions incur penalties as per IGNOU’s academic regulations. Always cross-verify the deadline on the IGNOU website under Student Services Assignments.
