Parent textbook: No ISBN available - instructor test bank/supplement for Chamberlain NR574 Acute Care Practicum I. Designed for AGACNP students mastering traumatic chest and abdominal injuries to achieve an A+ Grade. Aligned with Chamberlain NR574 curriculum and AACN Acute Care Nurse Practitioner Core Competencies. This resource covers all traumatic chest and abdominal injury topics including: cardiac tamponade (acute compression of the heart caused by fluid accumulation in the pericardial cavity, blood spills into pericardial sac restricting cardiac filling; Beck's Triad - jugular venous distention JVD, hypotension with narrow pulse pressure, muffled heart tones; treatment: pericardiocentesis as priority intervention to stabilize until surgery) ; tension pneumothorax (life-threatening air collection in pleural space causing mediastinal shift; clinical presentation: chest pain, hypotension, tachycardia, respiratory distress, anxiety, tracheal deviation away from injury, absent breath sounds, hyperresonance on percussion, distended neck veins; requires IMMEDIATE needle decompression with 14-gauge needle at 2nd intercostal space midclavicular line over the 3rd rib, followed by chest tube placement) ; open pneumothorax ("sucking chest wound" caused by chest wall defect open to pleural cavity; initial treatment: occlusive dressing taped on three sides creating flutter valve effect allowing air to escape but not enter, followed by chest tube placement, prophylactic antibiotics) ; flail chest (fracture of two or more adjacent ribs in two or more places allowing paradoxical chest movement; clinical findings: hypoxia, respiratory distress, crepitus, pain; management: humidified oxygen, pain management including intercostal nerve block or patient-controlled analgesia, pulmonary hygiene, incentive spirometry, ICU admission for elderly patients with multiple rib fractures) ; rib fractures (point tenderness, pain with breathing; mainstay treatment: adequate analgesia and pulmonary hygiene to prevent atelectasis and pneumonia; elderly patients with multiple rib fractures require ICU admission due to high risk of respiratory compromise) ; hemothorax (requires large bore chest tube 36-40 French to reduce risk of clotted hemothorax leading to lung entrapment or empyema; exploratory surgery indicated if 1500 mL drainage upon insertion or 200 mL/hour for 2-4 hours) . Abdominal injuries covered: liver lacerations (Grade I-II: observation ICU, bedrest, serial H/H monitoring, NPO; Grade IV-V most likely require surgical exploration or embolization; indications for exploratory laparotomy: hemodynamic instability, need for large quantities of blood products, signs of peritonitis, penetrating trauma regardless of grade) ; splenic injury (Kehr's sign - referred pain down left shoulder indicative of ruptured spleen; exploratory laparotomy priority for unstable patient; embolization contraindicated in patients 55 years due to thinning of splenic capsule; post-splenectomy vaccination requirements: Pneumococcal PCV13, Hib, Meningococcal, Meningococcal B administered 14 days post-surgery or before discharge) ; abdominal compartment syndrome (causes: gastric distention, ileus, bowel obstruction, peritoneal hemorrhage, ascites, bowel wall edema from high volume resuscitation, septic shock, massive transfusion, burns, obesity, positive pressure ventilation; physical exam: abdominal distention, rigid/firm abdomen, pain, nausea/vomiting, decreased urine output, shock symptoms; diagnosis via bladder pressure measurement with patient supine HOB ≤20 degrees; normal 12 mmHg, 12 mmHg = intraabdominal hypertension, 20 mmHg = abdominal compartment syndrome requiring decompressive laparotomy as surgical emergency) ; traumatic renal injury (risk factors: men under 30, rapid deceleration, direct blows to back/flank, penetrating injuries anterior to axillary line) .
