A nurse is reviewing the plan of care for a client experiencing an acute exacerbation of ulcerative colitis. Which of the following treatments should the nurse expect to administer?

Choice A: Potassium 2.5 mEq/L. This is the priority data collection finding that the nurse should identify according to the ABCDE principle, which prioritizes interventions based on airway, breathing, circulation, disability, and exposure. The nurse should identify potassium 2.5 mEq/L as the priority because it indicates hypokalemia, which is a low level of potassium in the blood. Potassium is an electrolyte that regulates the electrical activity of the heart and muscles. Hypokalemia can cause cardiac arrhythmias, muscle weakness, and paralysis, which can be life-threatening.

Choice B: Blood glucose 150 mg/dL. This is not the priority data collection finding that the nurse should identify for a client who has acute gastroenteritis. Blood glucose 150 mg/dL indicates hyperglycemia, which is a high level of glucose in the blood. Hyperglycemia can be caused by dehydration, stress, infection, or medication side effects.

Hyperglycemia can cause symptoms such as polyuria, polydipsia, polyphagia, and fatigue. It can also lead to complications such as diabetic ketoacidosis or hyperosmolar hyperglycemic state, which are serious but not as urgent as hypokalemia.

Choice C: Urine specific gravity 1.035. This is not the priority data collection finding that the nurse should identify for a client who has acute gastroenteritis. Urine specific gravity 1.035 indicates concentrated urine, which can be caused by dehydration or fluid loss. Dehydration can result from vomiting and diarrhea, which are common symptoms of acute gastroenteritis. Dehydration can cause symptoms such as dry mucous membranes, tachycardia, hypotension, and oliguria. It can also lead to complications such as shock or kidney failure, which are serious but not as urgent as hypokalemia.

Choice D: Weight loss of 3% of total body weight. This is not the priority data collection finding that the nurse should identify for a client who has acute gastroenteritis. Weight loss of 3% of total body weight indicates mild to moderate dehydration, which can be caused by fluid loss from vomiting and diarrhea. Weight loss can also reflect loss of muscle mass or fat tissue due to malnutrition or inflammation. Weight loss can affect the client’s nutritional status and immune function, but it is not as urgent as hypokalemia.

Choice A: Determine the client’s calcium level. This is the priority action for the nurse to take because the client might have hypocalcemia, which is a low level of calcium in the blood. Hypocalcemia can occur after a thyroidectomy due to accidental removal or damage of the parathyroid glands, which regulate calcium levels. Hypocalcemia can cause muscle spasms, tetany, paresthesia, and seizures.

Choice B: Give the client an oral potassium supplement. This is not an appropriate action for the nurse to take because the client might have hyperkalemia, which is a high level of potassium in the blood. Hyperkalemia can also occur after a thyroidectomy due to damage to the adrenal glands, which regulate potassium levels. Hyperkalemia can cause muscle weakness, arrhythmias, and cardiac arrest.

Choice C: Administer intravenous normal saline solution. This is not a necessary action for the nurse to take because the client does not have signs of dehydration or fluid imbalance. Normal saline solution does not affect calcium or potassium levels.

Choice D: Monitor the client’s peripheral pulses. This is an important action for the nurse to take, but not the priority. The nurse should monitor the client’s peripheral pulses for signs of decreased perfusion or ischemia, which can result from hypocalcemia or hyperkalemia affecting the cardiac function. However, this should be done after determining the client’s calcium level and correcting it if needed.
