A client who weighs 176 pounds is admitted to the intensive care unit with a serum glucose level of 600 mg/dL (33.3 mmol/L). Regular insulin at a rate of 0.1 unit/kg/hour is prescribed. The pharmacy provides a solution of regular insulin 100 units/100 mL of normal saline.

The nurse should set the infusion pump to deliver how many mL/hours?

(Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["8"]

Step 1: Convert the client's weight from pounds to kilograms. 176 pounds ÷ 2.2 = 80 kg

Step 2: Determine the total units of insulin needed per hour. 80 kg × 0.1 unit/kg/hour = 8 units/hour

Step 3: Determine the volume of insulin solution needed per hour. (8 units) ÷ (100 units/100 mL) = (8 units) ÷ (1 unit/mL) = 8 mL/hour

So, the nurse should set the infusion pump to deliver 8 mL/hour.

Correct Answer is B

Explanation

Choice A reason: Testing the urine for the presence of haematuria is important for diagnosing a urinary tract infection (UTI) or kidney stones, but it is not the most immediate intervention. Haematuria indicates blood in the urine, but assessing the client's vital signs is more urgent to determine if there is an acute issue that requires immediate attention.

Choice B reason: Measuring her temperature and heart rate is the most critical first step. These vital signs can provide immediate information about the client's overall condition and help identify potential systemic infection (fever) or hemodynamic instability (tachycardia). This information is essential for prioritizing further interventions and determining the urgency of the situation.

Choice C reason: Evaluating the urine for a strong Odor can help identify the presence of a UTI, but it is not as immediately critical as assessing the client's vital signs. Changes in urine Odor can support a diagnosis, but they do not provide the urgent information needed to assess the client's immediate health status.

Choice D reason: Palpating the right flank for tenderness is important for assessing kidney involvement, such as in cases of pyelonephritis (kidney infection). However, this physical examination should follow the assessment of vital signs to ensure the client is stable and not in immediate danger.

A. Determine if the client has a sliding scale insulin prescription. B. Stop the infusion until the healthcare provider is notified. C. Assess the client's urinary output for the previous 24 hours. D. Review the client's record for a history of diabetes mellitus.

Correct Answer is A

Explanation

Choice A reason: Determining if the client has a sliding scale insulin prescription is crucial. A sliding scale insulin regimen can help manage elevated blood glucose levels effectively. In the case of a capillary glucose of 365 mg/dL, prompt intervention is needed to prevent hyperglycaemia-related complications, and insulin administration is the most appropriate immediate action.

Choice B reason: Stopping the infusion until the healthcare provider is notified may not be the best immediate action. While it is essential to address the hyperglycaemia, halting the parenteral nutrition infusion can affect the client's overall nutritional and fluid balance. The focus should be on managing the glucose levels promptly.

Choice C reason: Assessing the client's urinary output for the previous 24 hours is important for monitoring overall fluid status and kidney function, but it does not directly address the immediate need to manage the elevated glucose levels.

Choice D reason: Reviewing the client's record for a history of diabetes mellitus can provide valuable information for long-term management and understanding the client's baseline glucose control. However, it is not the most urgent action in response to an acutely elevated capillary glucose level. Immediate intervention with insulin is needed to address the hyperglycaemia.
