A 12-lead ECG machine is used to measure the QTc interval in a patient starting methadone. The technician notices electrode lead II shows a flat line while all other leads record normally. The most likely cause is:
Answer: A loose or improperly connected left leg (LL) electrode
A single flat lead while others record normally indicates a poor or disconnected electrode contact, not a cardiac event.
Pulse oximetry is used in an addiction medicine setting to monitor a patient who has received naloxone for opioid overdose. A SpO2 reading of 88% on room air indicates:
Answer: Hypoxia requiring supplemental oxygen and further assessment
A SpO2 below 90% indicates significant hypoxia and necessitates supplemental oxygen and further clinical evaluation.
Carbon monoxide (CO) monitors are used in addiction medicine programs that treat tobacco use disorder. A CO meter reading of 7 ppm in an expired breath sample is most consistent with:
Answer: Recent light smoking or passive smoke exposure
Exhaled CO levels of 6–10 ppm are consistent with light recent smoking or significant passive exposure; heavy smokers typically read above 20 ppm.
When performing Clinical Opiate Withdrawal Scale (COWS) assessments, the nurse uses a handheld pupillometer to quantify pupil dilation. To ensure accurate readings, the device should be:
Answer: Calibrated and cleaned according to manufacturer specifications before each use
Regular calibration and cleaning of the pupillometer lens ensure accurate, reproducible pupil diameter measurements across patient assessments.
A blood pressure monitor in a detox unit fails to inflate to the set pressure and displays inconsistent readings. Which maintenance step should be performed first?
Answer: Inspect the cuff for cracks, air leaks, and ensure all tubing connections are tight
Cuff leaks or loose tubing connections are the most common causes of inflation failure and inaccurate BP readings, and should be checked first.
In a medication-assisted treatment clinic, a biometric fingerprint scanner used to verify patient identity before methadone dispensing repeatedly fails to recognize enrolled patients. The most likely technical cause is:
Answer: Sensor contamination from sweat, lotion, or dirt on patients' fingers or the sensor surface
Fingerprint scanners are prone to read errors when the sensor surface or patients' fingers are contaminated with sweat, lotion, or dirt.
A hospital-based addiction consult service uses an infusion pump to administer IV morphine during opioid rotation in a palliative patient. To prevent free-flow drug delivery, the nurse must ensure the pump has a functioning:
Answer: Anti-siphon valve and air-in-line detector
An anti-siphon valve prevents gravity-driven free flow if the pump loses power, while an air-in-line detector halts infusion if air enters the tubing.
