A patient suddenly develops sharp chest pain, severe breathlessness and a rapid pulse after several days of immobility. Which action is the priority?
Correct answer: C. Assess airway and breathing
- A. Encourage the patient to walk
- B. Administer oral fluids
- C. Assess airway and breathing
- D. Apply a warm pack to the calf
Explanation
The symptoms may indicate a pulmonary embolism, which can rapidly impair breathing and oxygenation. Airway and breathing assessment has priority before comfort measures or mobilisation. Walking may dislodge further clot, and oral fluids do not treat the immediate threat.
