A sedated ICU patient receiving assist-control ventilation suddenly becomes restless. The ventilator alarms sound, peak airway pressures drop significantly, and the patient is able to speak in a hoarse voice. SpO₂ falls from 96% to 84%. The endotracheal tube is visibly displaced above the vocal cords. What is the nurse’s priority action?

A 56-year-old patient with septic shock develops oozing from IV sites, petechiae, and new ecchymoses. Urine output has decreased over 4 hours. Labs: Platelets: 48,000/mm³ (normal: 150,000–400,000/mm³) PT: 22 sec (↑)  aPTT: 55 sec (↑) Fibrinogen: 120 mg/dL (↓) D-dimer elevated Lactate: 4.1 mmol/L (normal: 0.5–2.0 mmol/L) Which interventions should the nurse anticipate? (Select all that apply.)

A 45-year-old patient was admitted to the ICU following a severe traumatic brain injury (TBI). The healthcare team has conducted a neurological assessment and suspects brain death. The patient is on mechanical ventilation, and the family is asking if there is a chance of recovery. Which of the following assessment findings would confirm brain death? (Select all that apply.)

Ms. L. is a 72 year old female with a history of heart failure who presents to the emergency department with worsening dyspnea and decreased exercise tolerance over 4 days. She reports sleeping upright in a recliner. Assessment and results: RR: 30/min SpO₂: 88% on room air BP: 142/84 BNP: 1,200 pg/mL (< 100 pg/mL) Na⁺: 130 mEq/L (135–145 mEq/L) Creatinine: 1.6 mg/dL (0.6–1.3 mg/dL) Chest x-ray: interstitial and alveolar edema Echocardiogram last month: LVEF 28% Which interpretation is most accurate?

A sedated patient is on day 3 of mechanical ventilation with a cuffed ETT. The nurse plans the shift’s VAP-prevention bundle. Which interventions should the nurse include? (Select all that apply.)

A patient with known dilated cardiomyopathy is admitted for worsening heart failure. Current assessment findings: BP 102/66 mmHg HR 118, RR 28 SpO₂ 88% on 2 L nasal cannula New S₃ heart sound Bibasilar crackles with pink frothy sputum Fatigue and 1+ pedal edema Which finding indicates acute cardiogenic pulmonary edema requiring immediate intervention?

A 70-year-old patient with septic shock is emergently intubated for worsening hypoxemia. Immediately after intubation, the nurse notes SpO₂ improves to 94%, but the patient becomes hypotensive (BP 84/50). Breath sounds are unequal, with markedly diminished sounds on the left side. Which actions should the nurse take immediately? (Select all that apply)

A patient remains hypertensive with persistent crackles despite oxygen therapy. The provider states, “We need to reduce afterload to improve forward flow.” Which medication best addresses this physiologic goal?

A 63-year-old with severe pneumonia is intubated after failing high-flow oxygen. Immediately after intubation the nurse notes the following findings: SpO₂ 89% Breath sounds absent on the left, present on the right End-tidal CO₂ waveform present Condensation visible in the tube Which action should the nurse perform first?
