A nurse is preparing to administer oxygen to a client who has heart failure and is having severe difficulty breathing. Which of the following oxygen delivery equipment should the nurse select to provide the highest concentration of oxygen to the client?

A. Empty the urine drainage bag every 12 hours: While it's essential to empty the urine drainage bag regularly to prevent it from becoming too full, emptying it every 12 hours alone is not sufficient to prevent urinary tract infections (UTIs).
B. Drain the urine from the tubing before ambulation: Correct. Before the client ambulates or moves, the nurse should ensure that the urinary catheter's tubing is emptied. This prevents urine from flowing back into the bladder, reducing the risk of UTIs.
C. Use clean technique for urine specimen collection: While using clean technique during urine specimen collection is important for preventing contamination, it is not the primary action needed to prevent UTIs in a client with an indwelling urinary catheter.
D. Hang the urine drainage bag at the level of the bladder: While proper positioning of the drainage bag is essential for optimal urine flow and to prevent backflow, it alone is not sufficient to prevent UTIs.

The correct answer is Choice B.

Choice A rationale: Placing the client in a room with another client who has pharyngitis is not recommended. Pharyngitis can be caused by various different pathogens, not just streptococci. Co-housing clients with different infections can lead to cross-infection, complicating both clients’ conditions. Therefore, this choice is not the best option.

Choice B rationale: Ensuring that the client wears a surgical mask during transportation throughout the facility is the correct choice. Streptococcal infections are spread through respiratory droplets. A surgical mask can help prevent the spread of these droplets, protecting other clients and healthcare workers in the facility. This is a standard precaution in infection control.

Choice C rationale: Limiting the client’s visitors to visitations of 30 minutes is not necessarily beneficial. The duration of the visit does not significantly impact the risk of transmission as much as the precautions taken during the visit, such as hand hygiene and wearing a mask. Therefore, while limiting visitation time might reduce exposure, it is not the most effective measure to prevent the spread of infection.

Choice D rationale: Providing the client a room with negative pressure airflow of six air exchanges per hour is not necessary for a client with a streptococcal infection. Negative pressure rooms are typically used for clients with airborne diseases, such as tuberculosis. A streptococcal infection is spread through droplets, not airborne transmission, so a negative pressure room would not provide any additional benefit.
