How many sets of vital signs must be obtained and at what interval?

• A. One Set, Five Minutes Apart
• B. Two Sets, Five Minutes Apart
• C. Two Sets, Two Minutes Apart
• D. Three Sets, Five Minutes Apart

Answer: (B)

You’re looking for trend information in vital signs, not just a single snapshot. The correct approach is to obtain two sets of vital signs, five minutes apart. This interval lets you see whether the patient’s condition is stable or changing, which is crucial for safe disposition decisions in the field. A lone set could miss a deterioration or improvement, while two minutes apart wouldn’t give enough time for meaningful change to emerge, and three sets goes beyond what this policy requires. So, two sets, five minutes apart best supports accurate assessment and appropriate action.
