A nurse manager is providing an in-service for a group of nurses about thromboembolism.
Which of the following conditions should the nurse manager include as life-threatening? (Select All that Apply)

Choice A rationale

While MAP contributes to overall circulatory status which influences fluid balance, it does not directly determine a client's intake and output needs. Intake and output assessment is a broader measure of fluid balance, influenced by renal function, fluid administration, and insensible losses, rather than solely by MAP.

Choice B rationale

Resorption of cerebrospinal fluid (CSF) is primarily regulated by the arachnoid villi, which act as one-way valves for CSF flow into the venous sinuses. MAP influences cerebral blood flow, which in turn affects CSF production to some extent, but it does not directly determine CSF resorption.

Choice C rationale

Mean arterial pressure (MAP) is a critical determinant of cerebral perfusion pressure (CPP), which is the net pressure gradient driving blood flow to the brain. A MAP within the normal range (typically 70-100 mmHg) is necessary to ensure adequate cerebral blood flow and prevent ischemia or hyperemia following severe head trauma.

Choice D rationale

While MAP is a component of blood pressure and reflects the average arterial pressure throughout the cardiac cycle, stating that it "determines" regulation of blood pressure is circular reasoning. Instead, MAP is a *result* of complex physiological mechanisms that regulate systemic blood pressure, including cardiac output and systemic vascular resistance. .

Choice A rationale

Administering oral acetaminophen for pain control, while important, is not the immediate priority in a traumatic fall. The primary concern after trauma is to identify and address life-threatening injuries, especially those involving the head or internal organs. Pain management can be addressed once immediate threats are ruled out or managed.

Choice B rationale

Performing a thorough health history, though valuable for comprehensive care, is a time-consuming process and should not delay critical diagnostic interventions for potential internal injuries. In a traumatic fall, the focus must be on rapid assessment and intervention to prevent further neurological or systemic compromise.

Choice C rationale

A STAT non-contrast CT scan is crucial in a traumatic fall to quickly identify intracranial hemorrhage, fractures, or other significant internal injuries. Rapid diagnosis is essential for timely intervention, such as neurosurgical consultation, to minimize secondary brain injury or other adverse outcomes from occult trauma.

Choice D rationale

Inserting an indwelling urinary catheter to monitor output is generally a lower priority compared to assessing for life-threatening injuries. While important for fluid status, it can be deferred until the client's hemodynamic stability and neurological status have been thoroughly evaluated and stabilized following a traumatic event.
