A nurse is caring for a client who is receiving oxygen at 2 L/min via a nasal cannula. The nurse recognizes the client is receiving which of the following inspired oxygen concentration?

A) Asking the client to cough while inserting the NG tube:
This action is not necessary and may not be appropriate during the insertion of an NG tube. Coughing can increase the risk of gagging and aspiration during the procedure.

B) Wearing sterile gloves to insert the NG tube:
While the nurse should maintain appropriate hand hygiene, wearing sterile gloves is not typically necessary for the insertion of an NG tube. Clean gloves are sufficient for this procedure.

C) Placing the client into a left lateral position before inserting the NG tube:
Positioning the client in a high Fowler's position (sitting upright) or semi-Fowler's position is generally preferred for NG tube insertion to facilitate tube passage into the esophagus and reduce the risk of aspiration. Placing the client in a left lateral position is not typically done for NG tube insertion.

D) Determining the length of the NG tube to be inserted prior to the procedure:
This is the correct action. Before inserting the NG tube, the nurse should measure the distance from the tip of the client's nose to the earlobe and then from the earlobe to the xiphoid process or the mark on the NG tube corresponding to the desired insertion length. This helps ensure that the tube is inserted to the appropriate depth and reaches the desired location within the gastrointestinal tract.

A) "It's a good idea to help make sure your husband can sleep comfortably.":
This encourages the partner to administer medication, which can lead to overmedication and potential harm.

B) "Why do you think your husband needs more medication when he is asleep?":
This might cause the partner to feel defensive. It also does not provide the necessary education about the correct use of the PCA pump.

C) "Next time you think he needs more medication, call me and I'll push the button.":
This is inappropriate as well. It does not address the core issue that only the patient should be pressing the button to ensure safe and appropriate use of the PCA pump.

D) "Your husband should decide when more medication is needed.":
This educates the partner about the proper use of the PCA pump, emphasizing that only the patient should press the button to ensure they are receiving medication only when they feel pain. This minimizes the risk of overmedication and adverse effects.
