For patients 15 years or older, unstable status is defined by SBP below 90 mmHg plus any of the following signs of inadequate perfusion. Which list best fits?

For patients 15 years or older, unstable status is defined by SBP below 90 mmHg plus any of the following signs of inadequate perfusion. Which list best fits?

• A. Diaphoresis, severe dyspnea, significant chest pain of suspected cardiac origin, altered mental status, pallor
• B. Diaphoresis only
• C. No signs of perfusion issues
• D. High blood pressure

Answer: (A)

Unstable status in an adult patient is defined by a systolic blood pressure below 90 mmHg plus any sign that perfusion to vital organs is compromised. When blood flow falls, the body shows clues like sweating (diaphoresis) from sympathetic activation, trouble breathing (severe dyspnea) as the body struggles to deliver oxygen, chest pain that may come from cardiac ischemia, changes in mental status due to reduced cerebral perfusion, and pallor from diminished skin blood flow. Seeing multiple of these perfusion signs alongside a BP under 90 mmHg strongly indicates an unstable, hypoperfused state, which is why the list containing diaphoresis, severe dyspnea, significant chest pain of suspected cardiac origin, altered mental status, and pallor best fits. Diaphoresis alone can occur for reasons other than true hypoperfusion, and a patient with normal or high BP or with no signs of perfusion issues would not be considered unstable by this standard.
