The nurse is caring for a patient with ulcerative colitis and severe diarrhea.Which nursing assessment is the highest priority?

Choice A rationaleBlood pressure is a critical indicator of hemodynamic stability, which can be severely compromised in a patient with ulcerative colitis and severe diarrhea due to significant fluid and electrolyte loss. Hypovolemia resulting from dehydration can lead to decreased blood pressure and inadequate tissue perfusion, making this a high priority assessment. Normal blood pressure is typically around 120/80 mmHg.Choice B rationaleSkin integrity is important to assess in patients with diarrhea due to the increased risk of skin breakdown in the perianal area from frequent bowel movements and irritation. While important for preventing complications, it is not the highest priority compared to assessing hemodynamic stability in the context of severe diarrhea.Choice C rationaleAbdominal percussion is part of the abdominal assessment and can provide information about bowel sounds and distension, which might be relevant in ulcerative colitis. However, in the immediate context of severe diarrhea, assessing the patient's fluid balance and cardiovascular status takes precedence.Choice D rationaleHeart rate and rhythm are crucial indicators of cardiovascular status and can be significantly affected by fluid and electrolyte imbalances resulting from severe diarrhea in ulcerative colitis. Tachycardia (increased heart rate) and arrhythmias can occur due to dehydration and electrolyte shifts, making this a high-priority assessment. Normal resting heart rate for adults is typically between 60 and 100 beats per minute.
