Learning Objectives
By the end of this scenario, the learner will be able to:
- Identify the components of the chain of infection within a clinical patient scenario.
- Select appropriate infection prevention interventions (e.g., hand hygiene, PPE use, isolation precautions) at key decision points.
- Apply clinical reasoning to interrupt the chain of infection and reduce the risk of transmission in a bedside care setting.

Clinical Scenario
You are a nurse on a busy medical-surgical unit. Your new patient, Mr. James Carter, is a 72-year-old male admitted from the emergency department with fever, productive cough, and shortness of breath.
History
Vital Signs
- Temp: 38.6°C (101.5°F)
- HR: 104 bpm
- RR: 24/min
- BP: 132/78 mmHg
- SpO₂: 91% on room air
- Type 2 diabetes
- Recent hospitalization 2 weeks ago for urinary tract infection
- Lives in an assisted living facility
A chest X-ray confirms pneumonia. The provider suspects a possible infectious etiology and orders sputum cultures and initiation of antibiotics. As you prepare to begin care, you recognize multiple opportunities where the chain of infection could be interrupted—or allowed to continue.
Next
You are about to enter Mr. Carter’s room for your initial assessment. What do you do first?
Perform hand hygiene and don appropriate PPE based on suspected infection
Put on gloves only, since you will be touching the patient
Enter the room quickly to assess the patient since he is short of breath
Correct!
Perform hand hygiene and don appropriate PPE
This action interrupts the transmission phase of the chain of infection by reducing the spread of microorganisms. Based on suspected respiratory infection, appropriate PPE may include a mask in addition to standard precautions. Always assess required precautions before patient contact.
Next
Incorrect
Enter the room quickly — Incorrect
While urgency is important, skipping infection prevention steps increases the risk of transmitting pathogens. Hand hygiene is the most effective way to prevent infection spread. Even in urgent situations, take a few seconds to protect both yourself and the patient.
Next
Incorrect
Put on gloves only
Gloves provide some protection but are not sufficient alone. Hand hygiene must still be performed, and additional PPE may be required depending on the suspected infection. Remember: gloves do not replace proper hand hygiene.
