A male client who is admitted with bipolar disorder, manic psychosis, is placed in seclusion after unsuccessful attempts to de-escalate him during a sudden mood swing from laughter to jumping and screaming threats while waving a plastic dinner knife.

The client is given haloperidol.

5 mg intramuscularly STAT prior to seclusion.

Which intervention is most important for the nurse to implement immediately after seclusion?

The correct answer is 30 mL/hour.

Step 1 is to calculate the total amount of norepinephrine in the IV bag: 4 mg norepinephrine ÷ 1000 mL = 0.004 mg/mL

Step 2 is to convert the patient's weight from pounds to kilograms: 176 pounds ÷ 2.2 = 80 kilograms

Step 3 is to calculate the total amount of norepinephrine the patient will receive per minute: 2 mcg/min × 60 min = 120 mcg/min

Step 4 is to convert micrograms (mcg) to milligrams (mg): 120 mcg ÷ 1000 = 0.12 mg

Step 5 is to calculate the total volume of norepinephrine needed per hour: 0.12 mg ÷ 0.004 mg/mL = 30 mL/hour

Therefore, the nurse should program the infusion pump to deliver 30 mL/hour.

Choice A rationale:

Starting an insulin drip at 0.1 u/kg/hr is a common treatment for diabetic ketoacidosis (DKA). The goal is to lower blood glucose levels while avoiding a rapid decrease that could lead to cerebral edema. Insulin infusions allow for precise control of the rate and can be adjusted as needed based on the patient’s response.

Choice B rationale:

Giving a long-acting insulin dose is not typically done during the acute treatment of DKA. The patient has already taken a dose of insulin glargine at home. Additional doses of long-acting insulin could potentially lead to hypoglycemia.

Choice C rationale:

Providing an oral medication that enhances insulin production would not be beneficial in this case. The patient has type 1 diabetes, which means her body does not produce insulin. Therefore, medications that stimulate insulin production would not be effective.

Choice D rationale:

Changing the intravenous fluid to 5% dextrose and 0.45% sodium chloride with 20 mEq potassium can help prevent hypoglycemia and hypokalemia, which are potential complications of DKA treatment. As blood glucose levels decrease with treatment, dextrose can help maintain appropriate glucose levels. Potassium is often depleted in DKA and needs to be replaced.

Choice E rationale:

Having the client drink as much as they can tolerate would not be appropriate at this time. The patient is currently experiencing nausea and vomiting, which could be exacerbated by oral fluid intake. Additionally, she is NPO (nothing by mouth), likely due to her unstable condition.

Choice F rationale:

Giving 1 L of 0.9% sodium chloride IV can help correct dehydration, which is common in DKA due to excessive urination caused by high blood glucose levels.

Choice G rationale:

Promoting removal of electrolytes with a diuretic would not be beneficial in this case. The patient is likely already dehydrated and may have electrolyte imbalances due to DKA. Using a diuretic could exacerbate these issues.

Choice H rationale:

Giving a multivitamin is not typically part of the acute treatment for DKA. While overall nutritional status is important in managing diabetes, it would not address the immediate concerns of hyperglycemia and acidosis in DKA.

Choice I rationale:

Replacing potassium as needed is crucial in the treatment of DKA. Potassium levels can drop rapidly during treatment as insulin allows potassium to move back into cells. Low potassium (hypokalemia) can cause dangerous heart rhythms and muscle weakness.
