A patient experiencing discomfort because of severe arthritis would be described as having:

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.

Choice A rationale:

Offering an ice pack to place on the neck would not be an appropriate response in this situation. The patient has already complained that the ice massage is making the pain worse, so providing additional cold application may exacerbate their discomfort.

Choice B rationale:

The most helpful response in this scenario is to acknowledge the patient's discomfort and stop the cold application. Not everyone responds positively to cold therapy, and it's essential to respect the patient's feedback and provide alternative methods for pain relief.

Choice C rationale:

Alternating hot and cold applications may be helpful for some patients, but in this case, the patient has already expressed that the ice massage is exacerbating their pain. Suggesting this approach without addressing the patient's immediate concern is not appropriate.

Choice D rationale:

While it's true that the discomfort from the ice massage may subside in a few minutes, it's important to prioritize the patient's comfort and address their pain immediately. Continuing an intervention that is causing increased pain is not in the patient's best interest.
