Jo is a client with Type 1 Diabetes. Jo has a blood glucose level of 644 mg/dL. The nurse interprets that this client is most at risk of developing which type of acid-base imbalance?

Choice A reason: This statement is false. Asking the patient about home insulin doses is not the action that the nurse should take first. Insulin is a hormone that lowers the blood glucose level and can also lower the blood potassium level by driving potassium into the cells. However, this is not the primary cause of hypokalemia, or low blood potassium level, which can be due to other factors such as diuretics, vomiting, diarrhea, or alkalosis.

Choice B reason: This statement is true. Administering IV potassium supplements is the action that the nurse should take first. Potassium is an electrolyte that is essential for the normal function of the heart, muscles, and nerves. Hypokalemia can cause cardiac arrhythmias, muscle weakness, and paralysis. IV potassium supplements can restore the blood potassium level and prevent life-threatening complications.

Choice C reason: This statement is false. Placing the patient on a cardiac monitor is not the action that the nurse should take first. A cardiac monitor is a device that records the electrical activity of the heart and can detect any abnormal rhythms or conduction problems. It is a useful tool for monitoring the patient's cardiac status, but it does not treat the underlying cause of hypokalemia.

Choice D reason: This statement is false. Starting an insulin infusion at 0.1 units/kg/h is not the action that the nurse should take first. Insulin infusion is a method of delivering insulin continuously through a pump or a catheter. It is used for patients with diabetes who need tight glucose control. It can also lower the blood potassium level by driving potassium into the cells. However, this is not t

Choice A reason: This statement is false. 3% Sodium Chloride is a hypertonic solution that can cause fluid overload, hypernatremia, and cellular dehydration. It is not indicated for a patient with nausea, vomiting, and Salmonella infection, who is likely to have fluid and electrolyte losses.

Choice B reason: This statement is false. Dextrose 10% in water is a hypotonic solution that can cause fluid shifts, hyponatremia, and cellular edema. It is not indicated for a patient with nausea, vomiting, and Salmonella infection, who is likely to have fluid and electrolyte losses.

Choice C reason: This statement is true. 0.9% Sodium Chloride with 40 mEq Potassium (KCl) is an isotonic solution that can maintain fluid and electrolyte balance. It is indicated for a patient with nausea, vomiting, and Salmonella infection, who is likely to have fluid and electrolyte losses, especially sodium and potassium.

Choice D reason: This statement is false. Lactated Ringers is an isotonic solution that can maintain fluid and electrolyte balance, but it also contains lactate, which can be converted to bicarbonate in the liver. It is not indicated for a patient with nausea, vomiting, and Salmonella infection, who may have metabolic acidosis due to diarrhea and lactate accumulation.
