Final answer:
Patients with signs and symptoms of acute pulmonary edema and a heart rate of 90 may receive prehospital treatment including oxygen therapy, nitroglycerin, furosemide, and morphine.
Step-by-step explanation:
Pulmonary edema is a condition characterized by excess fluid in the air sacs of the lungs, often caused by heart or kidney failure. When a patient presents with signs and symptoms of acute pulmonary edema, such as difficulty breathing and chest pain, prehospital treatment may include several interventions:
- Oxygen therapy: Administering supplemental oxygen can help improve oxygenation and relieve respiratory distress.
- Nitroglycerin: This medication can be given to help reduce the workload on the heart and decrease chest pain.
- Furosemide: Also known as a diuretic, furosemide helps to promote the excretion of excess fluid from the body, reducing the fluid accumulation in the lungs.
- Morphine: In some cases, morphine may be administered to relieve anxiety, pain, and improve the patient's breathing.
These treatments aim to improve the patient's symptoms while they are being transported to a hospital for further evaluation and management.
