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: Jugular vein distention is more commonly associated with right ventricular heart failure, as it indicates increased central venous pressure.

Choice B reason: Bilateral basilar crackles are a hallmark sign of left ventricular heart failure. They occur due to pulmonary congestion and enema, resulting from the left ventricle's inability to effectively pump blood out to the body, causing fluid to back up into the lungs.

Choice C reason: 3+ pitting enema in the ankles is more characteristic of right ventricular heart failure, where fluid accumulates in the peripheral tissues.

Choice D reason: Hepatomegaly with right upper quadrant (RUQ) tenderness is also more indicative of right ventricular heart failure, as it reflects congestion in the liver due to increased venous pressure.

A. Haemoglobin A1C of 6.2%. B. Fasting plasma glucose of 189 mg/dL (10.49 mmol/L). C. Postprandial plasma glucose of 225 mg/dL (12.49 mmol/L). D. High-density lipoprotein of 40 mg/dL (1.03 mmol/L).

Correct Answer is A

Explanation

Choice A reason: Haemoglobin A1C of 6.2% is the best indication of long-term adherence to the prescribed diabetic regimen. The A1C test measures the average blood glucose levels over the past two to three months. A result of 6.2% indicates that the client has been maintaining good blood glucose control over this period, which reflects adherence to the regimen.

Choice B reason: Fasting plasma glucose of 189 mg/dL (10.49 mmol/L) is higher than the normal range. This result indicates poor short-term blood glucose control and suggests that the client may not be adhering to the prescribed regimen effectively.

Choice C reason: Postprandial plasma glucose of 225 mg/dL (12.49 mmol/L) is also higher than the recommended level for post-meal glucose. This result points to poor post-meal glucose control and suggests that the client may not be following their dietary or medication plan properly.

Choice D reason: High-density lipoprotein (HDL) of 40 mg/dL (1.03 mmol/L) is slightly below the recommended level for HDL cholesterol. While HDL is important for cardiovascular health, it is not a direct measure of blood glucose control or adherence to a diabetic regimen.
