Final answer:
True, each of the four conditions mentioned — unstable hemorrhage, high fever (105ºF or higher), hypoglycemia, and pulselessness/breathlessness — are always considered unstable and can be life-threatening if not immediately addressed.
Step-by-step explanation:
The statement lists four conditions — unstable hemorrhage, high fever (105ºF or higher), hypoglycemia, and pulselessness/breathlessness — and asks if they are always unstable. The answer is True. Unstable hemorrhage can lead to hypovolemic shock, which is life-threatening as it prevents the circulatory system from maintaining adequate blood flow and oxygen delivery. A high fever, particularly one that exceeds 105ºF, is considered hyperpyrexia and can be fatal if not promptly treated. Hypoglycemia, or low blood sugar, can cause unconsciousness, seizures, and even death if severe and not corrected quickly. Pulselessness and breathlessness are signs of cardiac arrest, a critical condition requiring immediate medical intervention.
