CCRN Test 04: Clinical Priorities

This exam reviews clot-busting drugs, lung taps, and heart emergencies.

Stroke Safety: Never give clot-busting drugs (tPA) to a patient who has had a brain bleed. It can be fatal.
Heart Check: If you see extra heart beats (PVCs), check the patient first. Check their pulse and BP before calling the doctor.
Clean Care: Once a bottle of sterile water is opened, you cannot use it again for a sterile field. The lid is dirty.

Test 04 Key Study Points

1. Empyema Pus in the lung space has very low sugar and a low pH. It means a bad infection is present.
2. Breathing Tubes Keep the cuff pressure below 22 mmHg (30 cmH2O). Too much pressure can hurt the windpipe.
3. Blood Transfusions Only use 0.9% Normal Saline with blood. Other fluids can make blood cells pop or clump.
4. Legal Proxy If a patient cannot think clearly, their legal guardian or health proxy must sign for surgery.
