A nurse in an emergency department is assessing four clients. Which of the following clients should the nurse see first?

Rationale: A. A client who reports a sudden onset of dizziness when sitting up: Although concerning, dizziness on position change may indicate orthostatic hypotension and is not immediately life-threatening. This client requires monitoring but is not the top priority based on airway or circulatory compromise. B. A client who has new onset urticaria and angioedema: New urticaria and angioedema suggest a potential anaphylactic reaction, which can quickly progress to airway obstruction. This is a life-threatening emergency requiring immediate intervention to secure the airway and administer epinephrine. C. A client who has numerous rectal polyps and blood-tinged stools: This condition could indicate a colorectal condition such as polyposis or malignancy, but it is not acutely life-threatening. The client needs evaluation, but not before those with airway or circulatory risks. D. A client who has a subluxation of the fifth digit on the left foot: A subluxation is a partial dislocation, which can be painful but does not involve vital organ systems. This musculoskeletal issue is stable and can be addressed after more urgent needs are met.
