A nurse is preparing to administer an intermittent enteral feeding through a small-bore NG tube. Which of the following actions should the nurse take before initiating the feeding?
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
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 B
Explanation
A. Incentive spirometer:
An incentive spirometer is used to encourage deep breathing and prevent respiratory complications, but it is not specifically indicated for the management of sleep apnea.
B. Continuous positive airway pressure (CPAP) machine.
The description of the client stopping breathing for 30-second intervals while sleeping at night is suggestive of sleep apnea. A Continuous Positive Airway Pressure (CPAP) machine is commonly used for the management of sleep apnea. It delivers a continuous stream of air to keep the airway open, preventing pauses in breathing during sleep.
C. Yankauer suction equipment:
Yankauer suction equipment is used for oral suctioning and is not related to addressing the breathing pauses associated with sleep apnea.
D. Nebulizer:
A nebulizer is used to administer inhaled medications, typically for respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). It is not the primary equipment for addressing the respiratory pauses seen in sleep apnea.
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.
