Flush the tube with 5 mL of water.

Test the pH of fluid aspirated from the tube.

Inject air through the tubing and auscultate for gurgling sounds:

Change the bag and tubing system every 12 hr

Answer and Explanation

The Correct Answer is B

A. Flush the tube with 5 mL of water:

Explanation: Flushing the tube with water is a routine practice before and after administering medications or feedings to maintain tube patency. However, it is not the primary action to confirm tube placement.

B. Test the pH of fluid aspirated from the tube (Correct Answer):

Explanation: Testing the pH of aspirated fluid helps confirm that the tube is in the stomach. A pH between 1 and 5 is generally indicative of gastric placement.

C. Inject air through the tubing and auscultate for gurgling sounds:

Explanation: This method is an older practice and is not recommended as a reliable method for verifying tube placement. Testing the pH is a more accurate and preferred method.

D. Change the bag and tubing system every 12 hr:

Explanation: Changing the bag and tubing system every 12 hours is a routine practice to maintain the integrity of the enteral feeding system. However, it is not specifically related to the initial steps in verifying tube placement.

Correct Answer is ["125"]

Explanation

To calculate the IV pump rate (mL/hr), you can use the following formula:

Rate (mL/hr) = Total Volume (mL)/Total Time (hr)

In this case:

Rate=500 mL/4 hr

Rate=125mL/hr

Therefore, the nurse should set the IV pump to deliver 125 mL/hr for the lactated Ringer's IV infusion over 4 hours, rounded to the nearest whole number.

Correct Answer is ["0.5"]

Explanation

To calculate the number of tablets the nurse should administer, you can use the following formula:

Number of Tablets =Total Dose (mg)/Dose per Tablet (mg)

In this case:

Number of Tablets=2.5 mg/5 mg/tablet

Number of Tablets=0.5

Therefore, the nurse should administer 0.5 tablet of lisinopril 5 mg to achieve the prescribed dose of 2.5 mg, rounded to the nearest tenth.
