Zorluk: OrtaReduction of Risk Potential

An LPN/LVN is assisting a female client with limited mobility in collecting a midstream clean-catch urine specimen. To reduce the risk of sample contamination, arrange the following steps in the correct sequence.

  1. 1Perform hand hygiene and apply clean exam gloves.
  2. 2Cleanse the urethral meatus using antiseptic wipes in a front-to-back motion.
  3. 3Direct the client to begin voiding a small amount of urine into the toilet or bedpan.
  4. 4Position the sterile collection cup into the active stream of urine.
  5. 5Remove the specimen container from the stream before the client completely finishes voiding.

Cevap

The nurse should first perform hand hygiene and don gloves, then cleanse the meatus from front to back. Next, the client should begin voiding to flush the urethra. The nurse then catches the midstream sample and removes the cup before the voiding is complete.
To obtain an uncontaminated midstream clean-catch urine specimen, the nurse must follow a strict procedural sequence: apply personal protective equipment, cleanse the meatus from front to back, allow the initial stream to flush the urethra, collect the midstream sample, and remove the cup before the client finishes voiding. This ensures the laboratory results reflect the actual bladder contents rather than external flora.

Adım Adım Çözüm

1
Perform hand hygiene and apply clean exam gloves.
The nurse is prepared to assist the client using standard precautions.
Prevents the introduction of the nurse's flora to the client and protects the nurse from exposure to body fluids.
2
Cleanse the urethral meatus using antiseptic wipes in a front-to-back motion.
The external genitalia are cleansed of surface bacteria.
Front-to-back cleansing prevents the introduction of gastrointestinal pathogens into the urinary tract and specimen.
3
Direct the client to begin voiding a small amount of urine into the toilet or bedpan.
The distal urethra is flushed with the initial flow of urine.
The initial stream clears microorganisms that naturally colonize the urethral opening.
4
Position the sterile collection cup into the active stream of urine.
The midstream urine is collected in the sterile container.
Midstream urine provides the most accurate reflection of bladder contents for laboratory testing.
5
Remove the specimen container from the stream before the client completely finishes voiding.
The collection is completed without contamination from the end of the urinary stream.
The final drops of urine can pick up skin flora from the external genitalia, potentially skewing the test results.

Anahtar Kavram

The purpose of a midstream clean-catch urine specimen is to obtain a sample that is free of external contamination. Proper sequencing ensures that external flora and urethral contaminants are cleared before the actual sample is collected into the sterile container.
