Question

Which of the following signs may be present with sudden and severe cerebral hypoxia? (Choose all correct answers)

1. Decreased level of consciousness
2. Loss of muscular tone
3. Generalized seizures
4. Pupil dilation

Answer 1

The signs that may be present with sudden and severe cerebral hypoxia include decreased level of consciousness, loss of muscular tone, generalized seizures, and pupil dilation. All provided options may be signs of this critical condition.

Step-by-step explanation:

The question concerns the signs of sudden and severe cerebral hypoxia, which is a critical medical condition where there is a significant deficit of oxygen to the brain. The signs that could be present with this condition include:

• Decreased level of consciousness: As oxygen supply to the brain is compromised, cognitive functions are impaired, leading to confusion, reduced alertness, and potentially loss of consciousness.
• Loss of muscular tone: Hypoxia can lead to decreased muscle control and tone, resulting in weakness or limpness.
• Generalized seizures: The lack of oxygen can trigger seizures due to the resulting electrical disturbances in the brain.
• Pupil dilation: This is a response to increased sympathetic activity in the body, which can occur in reaction to hypoxia to maximize light intake and possibly heighten awareness, though this occurs primarily as part of the fight-or-flight response.

Thus, all of the provided options may be present during an episode of severe cerebral hypoxia.
