A client who weighs 176 pounds receives a prescription for norepinephrine 2 mcg/min intravenously (IV). The IV bag is labeled, "Norepinephrine 4 mg in dextrose 5% in water (D;W) 1,000 mL." How many mL/hour should the nurse program the infusion pump? (Enter numerical value only.).

Answer and Explanation

The Correct Answer is ["30"]

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.

Correct Answer is C

Explanation

Choice A rationale:

Ketonuria is not a common complication of diabetes insipidus. Ketonuria is associated with diabetes mellitus, a different condition that results in the accumulation of ketones in the urine due to insufficient insulin.

Choice B rationale:

Peripheral edema is also an unlikely complication of diabetes insipidus. Diabetes insipidus is characterized by excessive thirst and urination, not fluid retention or peripheral edema.

A. Drink electrolyte fluid replacements. B. Give a dose of regular insulin as prescribed. C. Resume normal physical activity. D. Measure urine output over the next 24 hours.

Correct Answer is B

Explanation

Choice A rationale:

Drinking electrolyte fluid replacements may be necessary if the client is dehydrated due to diabetic ketoacidosis (DKA). However, addressing the increased thirst, which is a sign of DKA, should involve insulin administration to correct the underlying problem of high blood sugar.

Choice B rationale:

Giving a dose of regular insulin as prescribed is the most appropriate action to address increased thirst in a client with type 1 diabetes and early signs of DKA. Elevated blood sugar levels are the cause of the increased thirst, and insulin helps lower blood sugar levels.

Choice C rationale:

Resuming normal physical activity may not be advisable when a client is experiencing early signs of DKA. Strenuous physical activity can exacerbate hyperglycemia, and the primary focus should be on insulin administration and rehydration.

Choice D rationale:

Measuring urine output over the next 24 hours is important for monitoring hydration status in a client with DKA. However, the immediate priority is to address the increased thirst and hyperglycemia with insulin therapy.
