In-patient cardiac arrest is often preceded by changes in the patient's vital signs.

In-patient cardiac arrest is often preceded by changes in the patient's vital signs.

• A. Airway Obstruction
• B. Changes in the patient's vital signs
• C. Skin Temperature
• D. Oxygen Saturation

Answer: (B)

When someone is headed toward cardiac arrest, there is usually a detectable change across multiple vital signs rather than a single isolated abnormal value. This pattern of deterioration—e.g., rising or irregular heart rate, falling blood pressure, increasing or irregular breathing, and altered mental status or reduced urine output—provides an early warning that the patient is losing compensatory ability. Recognizing these trends gives clinicians a chance to intervene with escalation of care or resuscitation efforts before full arrest occurs. Airway obstruction can cause acute problems, but it’s not the typical, gradual pre-arrest signal that clinicians monitor across several vitals. Skin temperature isn’t a reliable early indicator of impending arrest, and while oxygen saturation is important, it’s one part of the broader picture of changing vital signs. The essence is that changes in vital signs signal deterioration toward arrest, making that option the best choice.
