A Quick Set of Vitals That Is Not Quick
At 06:15 you are asked to 'just get a quick set' on Mrs. Okafor, 64, admitted for pneumonia, because the assigned tech was pulled to an emergency. She is on 2 L nasal cannula. Your readings: oral temperature 38.6 C (101.5 F), pulse 118 and irregular, blood pressure 98/56, respirations 26, SpO2 90% on 2 L. Her hands are cold, and both hands have acrylic nails with dark polish. She is drowsy but wakes to voice and answers questions slowly. Last night's charted values were 132/78, pulse 88, and SpO2 95% on 2 L. The primary nurse is in a code on another unit, and the charge nurse is at the desk doing admissions.
1. Sort these findings into 'act now,' 'recheck before reporting,' and 'explainable artifact.' Justify each choice.

Act now - the trend, not just the number:
- SpO2 90% on 2 L in a patient admitted for pneumonia, down from 95% on the same oxygen. This is the most concerning value.
- Pulse 118 and irregular, up from 88. New irregularity plus tachycardia is a change in rhythm until proven otherwise.
- BP 98/56, roughly 34 mmHg below her baseline systolic.
- The 38.6 C fever matters less as a single number (she has pneumonia) than as part of the cluster.
Recheck before reporting: blood pressure (cuff size, arm position, repeat after 2 minutes) and the pulse (count a full 60 seconds).
Possible artifact: the SpO2 may be falsely low from cold hands and dark acrylic nails, and an irregular rhythm makes some monitors unreliable - but artifact is a reason to retest, never a reason to delay escalation. A drowsy patient with fever, tachycardia, hypotension, and desaturation is deteriorating until someone senior says otherwise.
2. What exactly do you do to make the SpO2 and pulse readings trustworthy before you escalate?

Fix the measurement, not the result.
- Check the oxygen delivery first: are the prongs actually in the nares, kinked, or set to 2 L? A dislodged cannula explains a drop and takes seconds to find.
- Warm the hand and confirm a good plethysmographic waveform and perfusion indicator; a flat or erratic waveform is not a valid reading.
- Move the probe to a different finger, or to the earlobe or forehead if the probe allows. Nail polish and acrylics can block light transmission; if polish must be removed, ask the patient first.
- Compare with the other hand and with her work of breathing and mentation.
- Count the radial pulse for a full 60 seconds and compare with the monitor - a monitor rate on an irregular rhythm can be wrong.
- Count respirations for 60 seconds without announcing it.
- Never chart a value you did not actually obtain. If you cannot get a reliable saturation, document that and report the failure along with the clinical picture.
3. Write what you would say to the charge nurse, and what you do if she says, 'I will get to it after these admissions.'

SBAR, with numbers and the trend:
- S: 'Mrs. Okafor in 412, pneumonia, on 2 L. Her 06:15 vitals have changed from her baseline.'
- B: 'At 22:00 she was 132/78, pulse 88, SpO2 95% on 2 L.'
- A: 'Now she is 90% on 2 L with a reliable waveform after I moved the probe and warmed her hand, pulse 118 and irregular, BP 98/56 on repeat, temp 38.6, and she is drowsy but arousable. I am worried about her.'
- R: 'I need someone to assess her now, and I need to know what you want me to do until then.'
If deferred: restate the concern in one sentence with the trend, ask for a specific time, and ask who else can come. Stay with the patient, keep her upright if that helps her breathing, recheck in 5–10 minutes, and do not change the oxygen flow rate yourself - that needs an order and a reassessment.
Document: the readings, the retest techniques, the name of the person notified, the times, and the response.
