462 LAB STUDY GUIDE & PRACTICE REVIEW 2026/2027
Which items are safety concerns during oxygen administration? - ANS ✔✔- Fall risk with oxygen tubing
- Flammable
- Skin breakdown behind ears
Match the oxygen device with the correct flow rate and percentage: - ANS ✔✔- Nasal cannula = 1-6
Liters- 22-44% FiO2
- Non-rebreather mask = 15 Liters, 60-90% FiO2
- Simple Mask = 5-10 Liters, 40-60% FiO2
Humidification should be used with any oxygen source if the oxygen is greater than 1/2 liter flow rate. -
ANS ✔✔False
Mrs. Keane was short of breath in the video scenario. What assessments should the student complete
prior to administering the oxygen via nasal cannula? - ANS ✔✔- 2 personal identifiers
- physician's orders
- auscultation of lung sounds
- pulse oximetry
Which are correct "rights" of medication administration. - ANS ✔✔- Medication
- Patient
- Time
- Route
- Dose
In the video, the student's patient has a new physician's order:
Titrate the flow rate of oxygen to maintain oxygen saturation at or above 92%. The nursing instructor
asks the nursing student to explain what titrate means. Which response indicates the student
understands what titrate means? - ANS ✔✔Titration means that the nurse/nursing student should adjust
the flow rate to keep the oxygen saturation at or above 92%.
The nurse will verify 2 patient identifiers prior to administering oxygen since it is a medication. To verify 2
patient identifiers, the nurse should compare the patients armband to the medical record. - ANS
✔✔True
Place the medication safety checks in the correct order: - ANS ✔✔1. After reading the MAR; read the
medication label whenever you select (pick up) the container or unit dose package.
2. Read it after you take it from the drawer and compare to the MAR.
3. Right before you give it to the medication to the patient.
4. Documentation of the medication administration.
Match the correct definition with the correct initials: - ANS ✔✔- PRN = as needed
