Safety and Infection Control: A Comprehensive NCLEX Review

A 78-year-old female is admitted to the medical-surgical unit from a long-term care facility with a 3-day history of productive cough and fever. She has a history of dementia, hypertension, and osteoporosis. Upon assessment, the client is disoriented to time and place, frequently attempting to climb out of bed without assistance. Vital signs: T 101.8°F (38.8°C), HR 102 bpm, RR 24/min, BP 138/82 mmHg, SpO2 91% on room air. The physician suspects Methicillin-resistant Staphylococcus aureus (MRSA) in her sputum and has ordered a chest X-ray and IV Vancomycin.

Infection Control: Chain of Command

Nurses must identify the correct transmission-based precautions based on the pathogen's mode of spread. Standard precautions apply to all clients, but additional measures are required for specific organisms.

  • Contact: Used for multidrug-resistant organisms (MRSA, VRE) and C. diff.
  • Droplet: Used for Influenza, Pertussis, and Bacterial Meningitis.
  • Airborne: Used for TB, Measles, and Varicella (requires N95 and negative pressure).
