A nurse is caring for a client who states he recently purchased lavender oil to use when he gets the flu.
The nurse should recognize which of the following findings as a potential contraindication for using lavender?

The correct answer is choice C: Initiate continuous cardiac monitoring.

Choice A rationale:

Implementing fluid restrictions is not recommended for a child with diabetic ketoacidosis (DKA). DKA is characterized by severe dehydration due to osmotic diuresis, and fluid replacement is a critical component of treatment to restore hydration and circulatory volume.

Choice B rationale:

Monitoring vital signs every 8 hours is not sufficient for a child with DKA. DKA is an acute, life-threatening condition that requires close monitoring of vital signs to detect changes in the patient’s condition promptly. Vital signs should be monitored more frequently, typically every 1 to 2 hours, depending on the severity of the DKA and institutional protocols.

Choice C rationale:

Continuous cardiac monitoring is recommended for a child with DKA. DKA can lead to serious electrolyte imbalances, such as hypokalemia, which can cause cardiac arrhythmias. Continuous cardiac monitoring allows for the early detection and treatment of these potential complications.

Choice D rationale:

Administering subcutaneous insulin 30 minutes before meals is not appropriate for the acute management of DKA. In DKA, insulin is typically administered intravenously to rapidly decrease blood glucose levels and correct metabolic acidosis. Subcutaneous insulin is not used until the patient is stable and able to eat.

Choice A rationale:

Improved short-term memory. Donepezil is a medication used to treat Alzheimer's disease and other forms of dementia. It works by increasing the levels of certain chemicals in the brain that are involved in memory, thinking, and reasoning. Therefore, improved short-term memory is an indication that the medication is effective, as it suggests enhanced cognitive function in the client.

Choice B rationale:

Enhanced mood. While improved mood can be a positive outcome of treating dementia, it is not the primary goal of donepezil therapy. The main focus is on cognitive improvement, particularly in memory and thinking skills. Enhanced mood alone may not be a reliable indicator of the medication's effectiveness in this context.

Choice C rationale:

Can perform ADLs independently. The ability to perform activities of daily living (ADLs) independently is an important aspect of a patient's overall well-being. However, this improvement may not solely be attributed to the effects of donepezil. Other factors, such as rehabilitation or support services, can also contribute to the patient's ability to perform ADLs. While it is a positive outcome, it is not a specific indication of donepezil's effectiveness.

Choice D rationale:

Increased food intake. Increased food intake is not a direct effect of donepezil. Donepezil does not have a primary role in regulating appetite or food intake. Therefore, this finding is not a reliable indicator of the medication's effectiveness in treating dementia.
