A nurse is assessing a toddler following the casting of the right arm due to a fractured humerus. Which of the following findings should the nurse identify as a manifestation of compartment syndrome?

A. A client who has measles: Measles is a highly contagious viral infection transmitted via airborne droplets that can remain suspended in the air for long periods. Implementing airborne precautions, including placing the client in a negative-pressure room and using an N95 or higher-level respirator, is essential to prevent transmission to others.

B. A client who has vancomycin-resistant enterococcus: VRE is transmitted primarily via contact with contaminated surfaces or direct contact with infected persons. Contact precautions, including gloves and gowns, are appropriate, but airborne precautions are not necessary.

C. A client who has pertussis: Pertussis (whooping cough) is transmitted through respiratory droplets, so droplet precautions, including a surgical mask for staff and visitors, are indicated. Airborne precautions are not required.

D. A client who has respiratory syncytial virus: RSV is primarily spread via contact with respiratory secretions and droplets. Contact and droplet precautions are recommended, but airborne precautions are not needed unless an aerosol-generating procedure is being performed.

A. Keep the urinary bag at bladder level when ambulating: The urinary drainage bag should always be kept below the level of the bladder to promote gravity drainage and prevent backflow of urine. Keeping it at bladder level increases the risk of urine reflux into the bladder, which can introduce bacteria and lead to infection.

B. Secure the catheter to the client's thigh: Securing the catheter prevents traction and movement at the urethral meatus, which can cause microtrauma and facilitate bacterial entry. Stabilization also maintains a closed drainage system, reducing the risk of catheter-associated urinary tract infections (CAUTIs).

C. Obtain urinary samples by disconnecting the tubing connections: Disconnecting the closed drainage system increases the risk of introducing microorganisms into the system. Urine specimens should be obtained from the designated sampling port using aseptic technique to maintain sterility and reduce infection risk.

D. Loop the tubing so that it is lower than the collection bag: Tubing should be free of dependent loops because these can trap urine and promote bacterial growth. Additionally, positioning tubing lower than the collection bag can lead to backflow, increasing the risk of infection.
