Which signs are associated with hypotension?

• A. Lightheadedness and cold, clammy skin
• B. Headache only
• C. Hypertension
• D. Nausea and vomiting

Answer: (D)

When blood pressure drops, tissues aren’t getting enough blood flow, so the body can show a range of signs related to reduced perfusion. Nausea and vomiting can occur in this state because decreased perfusion to the gastrointestinal tract and systemic stress responses often produce GI symptoms, especially in dehydration or shock where lower BP is involved. While lightheadedness with cold, clammy skin is a classic response to hypotension due to brain perfusion being affected and the body initiating vasoconstriction, the option that best fits the given context is nausea and vomiting, which reflects the broader systemic effects of low blood pressure on the GI system. Hypertension is the opposite of hypotension, and headache alone isn’t a reliable stand-alone sign of low BP.
