Q

Case 1 Problem list

A
  • Low SpO₂ & Type 1 Respiratory Impairment – SpO₂ 86% despite O₂ therapy, ABG confirms hypoxemia, likely due to post-op reduced lung expansion and pain.
  • Increased Work of Breathing (WOB)– RR 26, accessory muscle use, and diminished breath sounds indicate respiratory distress from pain, reduced lung compliance, or fluid shifts.
  • Weak Cough– Pain limits effective secretion clearance, increasing risk of atelectasis/pneumonia.
  • Reduced Lung Volume – CXR shows reduced expansion bilaterally, suggesting shallow breathing and atelectasis risk.
  • Cardiovascular (CV) Instability – HR 135, BP 142/92, pale/clammy, mild hypovolemia (-540mL balance) suggest stress response or fluid shifts.
  • Pain – VAS 8/10, limiting deep breathing, mobility, and recovery.

Q

Case 2 problem list

A

Low SaO₂ & Type I Respiratory Impairment
* SpO₂ 86% despite O₂ (FiO₂ 2L), ABG confirms hypoxemia.
* LLL consolidation on CXR reduces gas exchange.

Increased Work of Breathing (WOB)
* RR 26, accessory muscle use, apical breathing → signs of respiratory distress.
* Weak cough → risk of fatigue & worsening failure.

Sputum Retention
* Thick, green sputum with tactile fremitus, coarse crackles → impaired clearance.
* Risk of infection & worsening lung function.

Cardiovascular (CV) Instability
* HR 135, BP 142/92, flushed → possible infection, stress response, or dehydration.
* Negative fluid balance (-540 mL) suggests fluid shift post-op.

Infection
* Elevated WCC & CRP → suggests pneumonia or post-op infection.
* Recent laparotomy increases risk.

Pain
* VAS 8/10 → limiting deep breathing & coughing.
* * Poor control → worsens WOB, secretion clearance, and CV stress.

Q

Case 4 problem list

A
  • Low SpO₂ on oxygen – The patient has low oxygen saturation despite being on supplemental oxygen, indicating respiratory compromise.
  • Sputum retention – Due to neuromuscular weakness (MND), the patient is unable to cough effectively, leading to mucus buildup.
  • Type 2 respiratory failure (partially compensated) – Elevated pCO₂ with low pO₂ suggests ventilatory failure, likely due to weak respiratory muscles.
  • Reduced lung expansion – Apical breathing pattern and inability to cough suggest decreased lung compliance and ventilation.
  • High respiratory rate (RR) – Tachypnea (RR 30) indicates increased respiratory effort, possibly due to hypoxia or infection.
  • Cardiovascular instability (CV unstable) – Hypotension (BP 95/42) and signs of sepsis (high WCC, CRP) suggest hemodynamic compromise.
  • Poor urine output (UO) – 20 ml/hr suggests possible dehydration, shock
