A nurse is caring for a client who is being admitted for an acute exacerbation of ulcerative colitis. Which of the following actions should the nurse take first?

Choice A rationale Obtaining a dietary history is important for long-term management of ulcerative colitis to identify trigger foods that exacerbate symptoms. However, during an acute exacerbation, the patient is experiencing frequent, bloody diarrhea that poses an immediate threat to physiological stability. While nutrition is a concern, it is not the highest priority when the patient first presents with an acute flare, as systemic complications like dehydration and electrolyte imbalances take precedence in the initial nursing assessment and intervention. Choice B rationale Checking perianal skin integrity is a necessary action because frequent bowel movements can lead to skin breakdown and infection in the perianal area. While providing skin care and assessment is a vital nursing responsibility, it does not address the life-threatening systemic issues associated with an acute exacerbation. The nurse should perform this assessment, but only after ensuring that more critical physiological parameters, such as fluid and electrolyte balance, have been evaluated and stabilized first. Choice C rationale Chronic illnesses like ulcerative colitis can cause significant emotional distress, anxiety, and depression. Investigating the client's emotional concerns is a key part of holistic nursing care, especially since stress can sometimes trigger or worsen flares. However, in the acute phase of the disease, physical stabilization is the priority. Emotional support should be integrated into the care plan once the immediate physical risks associated with the exacerbation have been assessed and are being managed. Choice D rationale Reviewing electrolyte values is the priority action because an acute exacerbation of ulcerative colitis involves severe diarrhea, leading to the rapid loss of fluids and essential minerals. Potassium, sodium, and magnesium levels can drop dangerously, risking cardiac arrhythmias and muscle weakness. Normal potassium is 3.5 to 5.0 mEq/L, and sodium is 135 to 145 mEq/L. Assessing these values first allows the nurse to identify life-threatening imbalances and coordinate necessary intravenous replacement therapy immediately.
