The practical nurse (PN) is completing a focused assessment on a client who is prescribed oxygen at 3 liters per minute by nasal cannula. Which assessment finding by the PN requires immediate action?

The ﬂowmeter shows 1 liter of oxygen being delivered.

There is no humidifier attached to the delivery system.

The client is lying in a supine position in the bed.

The cannula is pressed snugly against the client's cheeks.

Answer and Explanation

The Correct Answer is A

This finding requires immediate action, as it indicates that the client is not receiving the prescribed amount of oxygen, which can compromise the oxygenation and perfusion of the tissues. The PN should adjust the ﬂowmeter to deliver 3 liters per minute of oxygen, and check for any leaks or kinks in the tubing.

The other options are not correct because:

B. The absence of a humidifier does not require immediate action, as it is not a critical component of the oxygen delivery system. A humidifier can help moisten the dry oxygen and prevent mucosal irritation, but it is not essential for oxygenation.

C. The supine position does not require immediate action, as it is not a contraindication for oxygen therapy. The client may prefer this position for comfort or rest, and it does not aﬀect the oxygen delivery or uptake.

D. The snug fit of the cannula does not require immediate action, as it is not a problem for oxygen therapy. The cannula should fit snugly against the client's cheeks to prevent dislodgment or slippage, and it does not interfere with the oxygen ﬂow or diﬀusion.

Correct Answer is C

Explanation

A. Skipped eating lunch would more likely cause hypoglycemia rather than diabetic ketoacidosis (DKA). When a person with type 1 diabetes skips a meal but still takes insulin, blood glucose levels drop, leading to hypoglycemia, not the elevated glucose and ketone production seen in DKA.

B. Incorrectly administered too much insulin would also result in hypoglycemia rather than DKA. Administering excessive insulin causes blood glucose levels to fall too low, which does not trigger the fat breakdown and ketone production that characterize DKA.

C. Had a cold and ear infection for the past two days is the most likely cause of diabetic ketoacidosis. Illness and infection cause the body to release stress hormones such as cortisol and adrenaline, which increase blood glucose levels and counteract insulin. In type 1 diabetes, insufficient insulin leads to hyperglycemia, fat breakdown for energy, and the production of ketones, resulting in DKA.

D. Ate an extra peanut butter sandwich before gym class would not cause DKA. Consuming extra food may raise blood glucose temporarily, but it would not lead to the severe insulin deficiency and ketone production seen in DKA, especially if the adolescent took insulin as prescribed.

A. Establish a second IV site. B. Stop the normal saline infusion. C. Assess the IV for blood return. D. Discontinue the 24 gauge IV.

Correct Answer is B

Explanation

A) Incorrect- While a second IV site might be considered if the first one is causing significant discomfort, it's not the initial intervention. The nurse should first address the immediate concern of pain.
B) Correct- Pain at the IV site during infusion might indicate infiltration or irritation. Stopping the infusion is the most immediate intervention to prevent further discomfort and potential complications like tissue damage.
C) Incorrect- While assessing for blood return is important to ensure proper IV placement, it's not the initial intervention for managing pain caused by the infusion.
D) Incorrect- Discontinuing the IV might be considered if the pain is severe and unmanageable, but the nurse should initially try to address the discomfort without removing the IV.
