Case Study

A 71-year-old client in a long-term care facility is being evaluated for nursing care related to vaccination and herd protection. The nurse reviews this trend: INR increasing from 2.0 to 4.5 without active bleeding. Which interpretation and action are most appropriate?

Question

A. Ignore the trend because one data point can be explained later.
B. Interpret the trend in context, compare it with baseline or benchmarks, and take the safest indicated action.
C. Treat a single value without comparing it with baseline, symptoms, or benchmarks.
D. Wait for a critical value or sentinel event before taking any nursing action.

Rationale

Correct answer: B. Interpret the trend in context, compare it with baseline or benchmarks, and take the safest indicated action.

Rationale: Trend questions require comparison with baseline, symptoms, risk, and benchmarks. Safe nursing action begins before a preventable event becomes critical.

Hint: Apply ABCs, client stability, and NCSBN clinical judgment steps before choosing an intervention.

Level: Advanced

Difficulty: Hard

Subtopic: Vaccination and herd protection
