A nurse is caring for a client who has a new arteriovenous (AV) graft in his left forearm. Which of the following techniques should the nurse use to assess the patency of this graft?

 

Choice A reason: The pH of urine can vary, but having a more alkalotic urine does not necessarily promote the growth of bacteria. Urine is typically slightly acidic, which helps to prevent bacterial growth.

Choice B reason: The primary anatomical reason for the higher rates of UTIs in clients who have vaginas is the shorter length of the urethra compared to those who do not have vaginas. This shorter distance makes it easier for bacteria from the skin or rectal area to enter the bladder.

Choice C reason: The strength of the detrusor muscle, which controls the emptying of the bladder, does not have a direct correlation with the frequency of UTIs. UTIs are more related to bacterial invasion rather than muscle strength.

Choice D reason: Bladder capacity is generally not a factor in the frequency of UTIs. While residual urine can increase the risk of UTIs, this is not typically related to overall bladder capacity.

Choice A reason: A distended bladder can cause low back pain due to the pressure and stretching of the bladder wall, which is often related to a urinary disorder such as urinary retention or obstruction.

Choice B reason: A stress fracture is less likely to be the cause of low back pain associated with an inability to void and a distended bladder.

Choice C reason: Nerve root pain typically presents with radiating pain down the leg rather than low back pain associated with urinary symptoms.

Choice D reason: Renal cancer could potentially cause low back pain, but it would not typically cause an inability to void or a distended bladder without other significant symptoms.
