A nurse is assessing a client for hypoxemia during an asthma attack. Which of the following manifestations should the nurse expect?

Rationale: A. Nausea is not a typical early manifestation of hypoxemia; it may occur later due to hypoxia-related fatigue or medication effects but is not expected. B. Dysphagia (difficulty swallowing) is not associated with hypoxemia during asthma; it is more related to structural or neurological issues. C. Hypotension can occur in severe or late hypoxemia, but it is not an early or expected manifestation during an asthma attack. D. Agitation is an early sign of hypoxemia because the brain is highly sensitive to decreased oxygen levels. Clients may become restless, anxious, or confused as oxygen levels drop.
