| Front (Question) | Back (Answer) | |------------------|---------------| | | Airway with C‑spine protection (A). | | TXA dose timing window | Within 3 hours of injury; give 1 g IV bolus over 10 min, then 1 g infusion over 8 h. | | Massive transfusion activation criteria | ≥ 10 units PRBCs/24 h or ≥ 4 units PRBCs in 1 h with ongoing bleeding. | | Pediatric fluid bolus (weight = 15 kg) | 20 mL/kg isotonic crystalloid → 300 mL . | | Best adjunct for C‑spine clearance in alert patient | NEXUS criteria (no midline tenderness, no intoxication, etc.). | | Recommended platelet:PRBC ratio in damage‑control resuscitation | 1:1 (or 1:1:1 with plasma). | | Indication for a pan‑scan | High‑energy mechanism + unstable vitals + unclear source of bleeding . | | Size of endotracheal tube for a 6‑year‑old | (Age/4) + 4 = (6/4)+4 ≈ 5.5 mm → use a 5.5–6 mm tube. | | First drug for analgesia in a hemodynamically unstable trauma patient | Ketamine (dissociative, maintains BP). | | Contraindication for chest tube placement | Anterior‑posterior (AP) chest wall injury with underlying organ at risk —instead, consider ventral thoracostomy or needle decompression . |

Integrating of these resources with your Quizlet set gives you a multimodal learning experience that is far more robust than relying on a single flashcard deck. 10. Wrap‑

| Quizlet Feature | How to Leverage It | |-----------------|-------------------| | | Build cards that summarize a concept (e.g., “TXA dosing: 1 g IV over 10 min, then 1 g over 8 h”). Avoid copying entire textbook paragraphs. | | Learn Mode | The spaced‑repetition algorithm helps you retain high‑yield facts (e.g., “C‑spine clearance criteria”). | | Match & Test | Simulate the exam environment by timing yourself; aim for < 30 seconds per question. | | Diagrams | Upload annotated anatomy sketches (e.g., “Thoracic trauma zones”). Visual memory sticks better than plain text. | | Collaborative Sets | Join a study group, but vet each card for accuracy; the 10th Edition has subtle updates that older sets may miss. |
