A nurse is preparing to administer 2 medications via client's NG tube. Which of the following actions should the nurse take?
Mix the 2 medications together prior to administration.
Add the medications to a small amount of theformula.
Flush the tube with at least 30 mL of sterile water prior to administering the medications.
Connect the NG tube to suction t min after administration of the medications.
The Correct Answer is C
A) Mix the 2 medications together prior to administration: It is not recommended to mix medications together before administering them through an NG tube unless specifically instructed by a healthcare provider or the pharmacy. Some medications can interact or precipitate when combined, which could reduce their effectiveness or cause harmful reactions. Therefore, it is safer to administer each medication separately, followed by a flush.
B) Add the medications to a small amount of the formula: Medications should not be mixed with enteral feeding formula, as it can affect the absorption of the medication and alter its effectiveness. Additionally, the medications could interact with components of the formula, leading to complications or reduced efficacy.
C) Flush the tube with at least 30 mL of sterile water prior to administering the medications: This is the correct action. Flushing the NG tube with 30 mL of sterile water before administering medications helps ensure the tube is clear and patent, preventing clogging. It also prepares the tube to receive the medications, ensuring proper delivery into the gastrointestinal tract.
D) Connect the NG tube to suction 10 minutes after administration of the medications: Connecting the NG tube to suction immediately after medication administration could remove the medications before they are absorbed. It is important to wait at least 30 minutes after administering medications before connecting the NG tube to suction to ensure the medication is absorbed adequately.

Correct Answer is C
Explanation
A) Wait 1 min between suctioning attempts: The nurse should wait 20 to 30 seconds between suctioning attempts, not a full minute. Waiting too long between attempts can cause the patient unnecessary distress. The goal is to allow for oxygenation and recovery of the airway in between suctioning attempts.
B) Apply intermittent suction for 30 seconds: Suctioning should be limited to 10 to 15 seconds at a time to prevent hypoxia and damage to the mucous membranes. Applying suction for 30 seconds could lead to complications such as hypoxia, mucosal trauma, and increased risk of infection.
C) Insert the catheter 10 cm (4 in.): This is the correct technique. For an adult client, the catheter should be inserted 10 cm (4 inches) into the airway. Inserting the catheter too far can cause trauma to the airway, while inserting it too shallow may not effectively clear secretions.
D) Apply suction while inserting the catheter: Suction should not be applied while inserting the catheter. Suctioning should only be applied while withdrawing the catheter, not while inserting it, to prevent mucosal trauma and to ensure effective clearance of secretions. Suctioning during insertion could damage the airway and increase discomfort for the client.
Correct Answer is B
Explanation
A) Place the client in Sims' position for catheter insertion: Sims' position (side-lying position) is not typically used for central venous catheter insertion. The client is usually placed in a supine or Trendelenburg position to help facilitate insertion and decrease the risk of air embolism during the procedure.
B) Prepare the client for a chest x-ray to verify catheter placement: After the insertion of a central venous catheter, a chest x-ray is routinely performed to verify the correct placement of the catheter in the superior vena cava or right atrium. This is essential to ensure the catheter is properly positioned and to check for complications like pneumothorax or inadvertent placement in the lung.
C) Use clean technique when changing the catheter dressing: When changing the dressing for a central venous catheter, sterile technique is required, not clean technique. Sterile technique minimizes the risk of infection, which is a major concern when caring for central venous access devices.
D) Verify the amount of TPN solution the client is receiving every 4 hr: While it is important to monitor the amount of TPN being infused and assess for complications, verifying the exact amount every 4 hours is not a standard procedure. Typically, TPN is managed and adjusted by the healthcare provider based on lab results, weight, and clinical status, but constant monitoring of the solution is not required.
