While caring for a client with Guillain-Barre syndrome, which finding should the practical nurse (PN) report to the charge nurse?

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.

Demonstrate how to administer medication via a feeding tube.The picture shows that the newly hired PN is about to make a serious error by adding the medication directly to the feeding bag, which can cause clogging, contamination, or inaccurate dosing of the medication. The PN should demonstrate how to administer medication via a feeding tube correctly, which involves stopping the feeding, flushing the tube with water, instilling the medication, flushing again, and resuming the feeding.

The other options are not correct because:

1. Confirming that the medication is only administered once daily is not relevant or helpful, as it does not address the error or teach the correct technique of administering medication via a feeding tube.Determining if the medication is compatible with the solution is not necessary or appropriate, as the medication should not be mixed with the solution in the first place, but given separately through the feeding tube.
2. Offering to assist in calculating the rate of flow for the mixture is not relevant or helpful, as there should be no mixture of medication and solution in the feeding bag, but separate administration of each through the feeding tube.
