Before leaving the room of a confused client, the nurse notes that a half-bow knot was used to attach the client's wrist restraints to the movable portion of the client's bed frame. What action should the nurse take before leaving the room?
Tie the knot with a double turn or square knot.
Ensure that the restraints are snug against the client's wrists.
Move the ties so the restraints are secured to the side rails.
Ensure that the knot can be quickly released.
The Correct Answer is D
Choice A: A double turn or square knot is not recommended because it is not a quick-release knot, which is necessary for patient safety in case of an emergency
Choice B: While restraints need to be secure, they should not be snug against the client's wrists. There should be enough space to fit two fingers between the restraint and the wrist to prevent circulation issues.
Choice C: Ties should not be secured to side rails as this can cause injury if the rails are moved. Instead, they should be attached to the movable part of the bed frame.
Choice D: This is the correct action. A half-bow knot is a type of quick-release knot, which is essential for the safety and quick release of the patient if needed

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 D
Explanation
This is the best intervention for the PN to implement because it monitors the client's fluid status and helps detect fluid overload, which can cause hypertension and neurological changes. The PN should weigh the client at the same time, on the same scale, and with the same clothing every day.
