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.
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 ["A","E"]
Explanation
The level of hypoxemia that the child may have experienced during the submersion depends on several factors, but the most important ones are:
- The **temperature of water**: Cold water can induce a diving reflex, which lowers the heart rate and oxygen consumption, and may protect the brain from hypoxic injury¹². Cold water can also cause laryngospasm, which prevents water aspiration but also impairs gas exchange.
- The **amount of time the child was submerged**: The longer the submersion, the more severe the hypoxemia and the higher the risk of brain damage and death. The survival rate decreases significantly after 5 minutes of submersion³.
The other factors are less relevant or not directly related to the level of hypoxemia:
- The **weight of the child**: This may affect the buoyancy and the ability to float or swim, but not the oxygen consumption or gas exchange during submersion¹.
- The **oxygen concentration of the ambient air**: This may affect the pre-submersion oxygen saturation, but not the rate of oxygen depletion or gas exchange during submersion¹.
- The **witnessing of the fall into the pool**: This may affect the time to rescue and resuscitation, but not the level of hypoxemia during submersion.
Correct Answer is ["B","C","E"]
Explanation
A) Incorrect- While hydration is important, this response doesn't directly address the client's question about the content and timing of meals.
B) Correct- Complex carbohydrates high in fiber content have a slower impact on blood glucose levels, promoting better glycemic control.
C) Correct- Bedtime snacks can be helpful to prevent nighttime hypoglycemia, but if heartburn develops, it may be necessary to modify the timing or content of the snack.
D) Incorrect- This response is not directly related to managing blood glucose levels or gestational diabetes.
E) Correct- Refined sugars can cause rapid spikes in blood glucose levels, so avoiding them helps maintain stable glycemic control.
