Certified Nursing Assistant (CNA) Practice Exam

What action by a nursing assistant can potentially prevent urinary tract infections in elderly residents?

1. Limiting fluid intake

2. Encouraging frequent handwashing

3. Encouraging ambulation

4. Encouraging the resident to drink plenty of fluids

The correct answer is: Encouraging the resident to drink plenty of fluids

Encouraging the resident to drink plenty of fluids is a key action that can help prevent urinary tract infections (UTIs) in elderly residents. Increased fluid intake helps to flush bacteria out of the urinary tract, thereby reducing the likelihood of infection. Staying well-hydrated promotes regular urination, which can help eliminate harmful microorganisms that might cause UTIs. It is especially important for elderly residents, as they may have a reduced sense of thirst and may not drink enough fluids, which can lead to concentrated urine and an increased risk of infection. While other options may play a role in overall hygiene and health, they don't directly correlate with preventing urinary tract infections as effectively as maintaining adequate fluid intake does. For instance, limiting fluid intake can actually increase the risk of UTIs. Encouraging frequent handwashing is important for general infection control but does not specifically address urinary health. Although encouraging ambulation can aid in overall well-being, it doesn't have the same direct impact on urinary function as promoting fluid consumption.
