A nurse is collecting data from a client who has diabetes mellitus.
Which of the following findings indicates that the client is experiencing DKA?

Choice A rationale:

Reporting a near-miss using the facility’s recommended protocol and correcting the error on the MAR is the appropriate action. A “near-miss” in healthcare is a situation where an error could have happened, but didn’t, either by chance or timely intervention. It’s crucial to report these incidents as they provide valuable information for risk management and quality improvement. By analyzing near-misses, healthcare facilities can identify potential hazards and take preventive measures to ensure patient safety. Correcting the error on the MAR is also important to prevent the same mistake from happening in the future.

Choice B rationale:

Reporting the near-miss to the next shift before the next dose is due is not the best course of action. While it’s important to communicate any potential issues to the next shift, it’s more crucial to report the incident immediately using the facility’s recommended protocol. This allows for a timely investigation and corrective action. Waiting until the next shift could delay these processes and potentially put patient safety at risk.

Choice C rationale:

Correcting the MAR error but saying nothing because nothing happened is not an appropriate response. Even though the error did not result in any harm, it’s still important to report it. Near-misses are often indicators of underlying system issues that need to be addressed. By not reporting the incident, the opportunity to improve patient safety and prevent future errors is lost.

Choice D rationale:

Notifying the pharmacy about the error they almost caused is not the most appropriate action. While it’s important to communicate with the pharmacy if they were involved in the error, the first step should always be to report the near-miss using the facility’s recommended protocol. This ensures that the incident is properly documented and investigated, and that appropriate corrective actions are taken.

Choice A rationale:

Phenytoin is an anticonvulsant drug used in the prophylaxis and control of various types of seizures. It has a narrow therapeutic index, which means that the safe and toxic plasma levels of the drug are very close to each other. This characteristic makes the dosing of phenytoin challenging, as even small deviations from the recommended therapeutic range can lead to suboptimal treatment or adverse effects. Therapeutic effect without clinical signs of toxicity occurs more often with serum total concentrations between 10 and 20 mcg/mL34. Therefore, clinicians are advised to initiate therapeutic drug monitoring in patients who require phenytoin.

Choice B rationale:

The statement that phenytoin has a low chance of being effective is incorrect. Phenytoin is a widely used and effective anticonvulsant. It works by slowing down impulses in the brain that cause seizures. It is used to control seizures but does not treat all types of seizures. The effectiveness of phenytoin is not determined by its narrow therapeutic index but by its pharmacological action in the brain.

Choice C rationale:

The assertion that there is no difference between safe and toxic plasma levels of phenytoin is incorrect. There is indeed a difference between the safe (therapeutic) and toxic levels of phenytoin. The therapeutic range for phenytoin is typically between 10 and 20 mcg/mL34. Levels above this range can lead to toxicity, while levels below this range may not provide the desired therapeutic effect.

Choice D rationale:

The statement that a very small dosage of phenytoin can result in the desired therapeutic effect is not entirely accurate. While it’s true that phenytoin is effective in controlling seizures, the dosage required to achieve this effect is not necessarily “very small”. The usual adult dose for seizures is 100 mg orally 3 times a day. The dosage may need to be adjusted based on individual patient factors and response to therapy. Therefore, it’s not accurate to generalize that a “very small” dosage will result in the desired therapeutic effect for all patients.
