A nurse is teaching a quality improvement course about decreasing the number of urinary tract infections for clients who have indwelling urinary catheters. Which of the following information should the nurse include in the teaching?

A. The client drank 240 mL of water at 0800: This is objective data because it is a measurable and observable fact that can be verified by the nurse. Documentation of intake is based on direct observation rather than the client’s perception.

B. The client's gait is steady while using a walker: This is objective data as it is based on the nurse’s direct observation of the client’s physical performance. It can be measured or assessed without relying on the client’s personal experience.

C. The client cries while answering questions: Crying is an observable behavior, making it objective data. While it may indicate distress, the nurse is reporting what was seen rather than the client’s internal experience.

D. The client points to a 6 on the visual analog pain scale: This is subjective data because it reflects the client’s personal perception of pain, which cannot be independently measured or verified. Pain is inherently subjective, relying on the client’s self-report.

A. "This medication can cause nausea and drowsiness.": Gastrointestinal upset and central nervous system effects such as drowsiness are common early adverse effects of lithium therapy. Clients should be informed so they can recognize mild side effects versus signs of toxicity.

B. "You will be placed on a low-sodium diet while taking this medication.": Lithium requires a consistent, not low, sodium intake. Low sodium can increase lithium reabsorption in the kidneys, raising the risk of toxicity. Emphasizing a consistent dietary sodium intake is important rather than restricting sodium.

C. "Blurred vision is an expected adverse effect of this medication.": Blurred vision is not an expected side effect of lithium and may indicate toxicity or another ocular issue. Clients should report changes in vision promptly rather than consider them routine.

D. "This medication can cause weight gain.": Weight gain is a known side effect of lithium therapy due to fluid retention and metabolic changes. Clients and caregivers should be aware to monitor weight and maintain healthy lifestyle practices.

E. "It will take at least a week before this medication reaches a therapeutic level.": Lithium requires several days to reach a therapeutic blood level, and effects on mood stabilization are gradual. Educating the client about delayed onset helps set realistic expectations and encourages adherence.
