A nurse evaluating the effectiveness of an Aquathermia K pad for the leg is aware that the patient who has the least risk for burn injury from this device would be the patient with:.

Choice A rationale:

Constipation is not a common adverse effect of pain medication administered by the epidural route. Pain medication primarily affects the central nervous system and does not typically impact the gastrointestinal system in a way that would lead to constipation.

Choice B rationale:

Hypoventilation is the correct answer. When opioids or other potent pain medications are administered by the epidural route, they can depress the respiratory center in the brain, leading to hypoventilation (slow or inadequate breathing). This is a critical concern and the most important adverse effect to monitor because it can lead to respiratory compromise or even respiratory arrest.

Choice C rationale:

Nausea can be a side effect of some pain medications, but it is not the most important adverse effect to monitor in a patient receiving epidural pain medication. Nausea can often be managed with antiemetic medications.

Choice D rationale:

Headache is not a common adverse effect of epidural pain medication. The administration of pain medication into the epidural space is localized to the spinal area and does not typically lead to headaches.

Choice C rationale:
The most crucial instruction regarding the safety of fentanyl patches is to apply them as directed by the primary care provider. Fentanyl is a potent opioid medication, and its misuse or improper application can lead to serious health risks, including overdose. Therefore, following the prescriber's instructions is of utmost importance to ensure the patient's safety.
Choice A rationale:
Storing fentanyl patches in a locked cabinet is a good practice to prevent unauthorized access and to keep them out of reach of children or individuals who should not have access to the medication. However, it is not the most critical safety instruction. Proper application and usage are more important.
Choice B rationale:
While preparing the skin by cleaning with an antiseptic scrub solution is a necessary step when applying a transdermal medication like a fentanyl patch, it is not the most critical safety instruction. It is a standard part of the application process but does not address the overarching safety concerns related to fentanyl use.
Choice D rationale:
Using fentanyl patches as needed for breakthrough pain without clear guidance from a healthcare provider is not a safe practice. Fentanyl is a potent medication with a high risk of overdose, and its use should always be closely monitored and directed by a healthcare professional. Self-adjusting the dosage without medical supervision can lead to serious safety issues.
