Before administering an antibiotic that can cause nephrotoxicity, which laboratory value is most important for the practical nurse (PN) to review?

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 injury. 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 submersion.

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 submersion.
• 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 submersion.
• 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.

Choice A rationale:

The client will have no signs of infection in the wound by day 7. Rationale: This outcome is appropriate because it sets a specific timeframe (day 7) for assessing the absence of infection in the wound. It provides a clear and measurable criterion for evaluating the effectiveness of the wound care plan.

Choice B rationale:

The client will report a pain level of 4/10 or less during dressing changes. Rationale: Pain management is an essential aspect of wound care. Setting a target pain level (4/10 or less) during dressing changes allows for monitoring and adjustment of pain management strategies, making it an appropriate outcome.

Choice C rationale:

The client will consume at least 75% of meals and snacks daily. Rationale: While nutrition is important for wound healing, this outcome is less directly related to the wound itself. Monitoring meal consumption is a valuable goal for overall health but may not be as closely tied to wound improvement as infection control, pain management, or wound care technique.

Choice D rationale:

The client will reposition self in bed every 2 hours with assistance. Rationale: Repositioning every 2 hours is an important preventive measure for pressure ulcer development. However, this choice may not be appropriate for this particular client if they are unable to reposition themselves, even with assistance. This outcome may not be achievable for all clients, and a more individualized goal may be necessary.

Choice E rationale:

The client will demonstrate proper wound care technique before discharge. Rationale: Ensuring that the client can perform proper wound care techniques independently or with minimal assistance is a crucial outcome. This ensures that the client can maintain wound hygiene and prevent complications after discharge.
