How should sterility be maintained while inserting a catheter?

• A. The dominant hand remains sterile (performs skin prep and insert catheter) while the nondominant hand is nonsterile (stabilize genitalia and expose the urethral meatus)
• B. Both hands remain sterile at all times
• C. The nondominant hand remains sterile and performs the prep
• D. Sterility is not required during catheter insertion

Answer: (A)

The key idea is preserving a sterile field during catheter insertion while still having access to expose the urethral opening. The dominant hand stays sterile to perform skin prep and insert the catheter, ensuring that sterile instruments and the catheter only contact sterile surfaces. The nondominant hand is kept nonsterile and is used to stabilize the genitalia and expose the urethral meatus without risking transfer of organisms to the sterile area. This separation minimizes contamination risk: you keep the critical insertion hand within the sterile field, while the other hand handles exposure and stabilization outside that field.
