Read Monitoring Data
Use patient evidence to read monitoring data without overclaiming.
- Sign vs. symptom: Clinical data mixes measured findings with patient-reported history.
- Normal range comparison: Students need a reference range or baseline to tell whether a value is concerning.
Prerequisites are inferred: pending teacher review.

Read a trend across timepoints: is the value rising or falling?
| Time | SpO2 (%) |
|---|---|
| 8:00 | 98 |
| 8:30 | 95 |
| 9:00 | 92 |
| 9:30 | 88 |
Using the monitor table, how does the SpO2 change from 8:00 to 9:30?
Reviewed| Time | SpO2 (%) |
|---|---|
| 8:00 | 98 |
| 8:30 | 95 |
| 9:00 | 92 |
| 9:30 | 88 |
- A.It stays exactly the same
- B.It falls steadily over time
- C.It rises steadily over time
- D.It rises and then falls

Answer: B. It falls steadily over time
- Step 1: List the values: The readings are 98, 95, 92, then 88.
- Step 2: Describe the trend: Each reading is lower than the one before, so it falls steadily.
Why it's right: The readings 98, 95, 92, 88 drop at every step, so the SpO2 falls steadily.
- A: The numbers change at each time, so it does not stay the same.
- C: The numbers go down, not up, so it is not rising.
- D: The numbers fall the whole time; they never rise first.

A pulse oximeter reads 98% at 8:00 and 88% at 9:30. How far did the reading fall, and over how long?
Reviewed- A.88 percentage points over 90 minutes
- B.12 percentage points over 90 minutes
- C.10 percentage points over 60 minutes
- D.10 percentage points over 90 minutes
Show the worked solution ▾
Answer: D. 10 percentage points over 90 minutes
- Step 1: Subtract the readings: 98 minus 88 is 10 percentage points.
- Step 2: Count the clock: 8:00 to 9:30 is one hour and thirty minutes, which is 90 minutes.
Why it's right: The reading dropped from 98% to 88%, a fall of 10 percentage points, across the 90 minutes from 8:00 to 9:30.
- A: 88 is the final reading, not the size of the drop.
- B: 98 minus 88 is 10, not 12.
- C: 8:00 to 9:30 is 90 minutes, not 60.

- A nurse watches a monitor trend to see whether a patient is getting better or worse.
Fill these in as you work through the lesson.
- Monitor reading (a value shown at one time):
- Trend (how the value changes over time):
- Alarm threshold (value that triggers action, e.g. SpO2 below 90%):
- SpO2 (oxygen saturation, a percent):
Read the value at each , follow the over time, and act when it crosses the alarm threshold.
- What is the value at this time?
- Is the value rising or falling?
- Has it crossed the alarm threshold?
Read the monitor table, describe the trend, and find when SpO2 first drops below 90%.
