Final answer:
A primary assessment includes checking O₂ levels, assessing LOC (level of consciousness), obtaining BP (blood pressure), and inquiring about allergies and medications.
Step-by-step explanation:
A primary assessment includes checking O₂ levels, assessing LOC (level of consciousness), obtaining BP (blood pressure), and inquiring about allergies and medications. Checking O₂ levels is important to ensure that the patient is receiving adequate oxygenation. Assessing LOC helps determine the patient's mental status and level of awareness. Obtaining BP is important to assess the patient's cardiovascular health. Inquiring about allergies and medications helps identify any potential risks or contraindications for treatment.
