40. A patient seeks medical attention at the urgent care center for a new onset of right-hand weakness. The patient reports occasional wrist pain with numbness of the thumb, index finger, and middle finger of the same hand. The advanced practice registered nurse (APRN) notes that the Tinel sign and Phalen maneuver reproduce the same symptoms in the patient. Which action should the APRN take to assist this patient?
Answer: C
Thumb spica splint is the appropriate action to assist the patient.
A thumb spica splint is designed to immobilize the thumb and wrist, providing support for conditions such as carpal tunnel syndrome, which aligns with the patient's symptoms of numbness and weakness.
A) Cold packs to the wrist
While cold packs may help alleviate pain and swelling, they do not address the underlying issue of nerve compression indicated by the patient's symptoms and positive Tinel sign and Phalen maneuver. Therefore, this option is inadequate for long-term management.
B) Referral to a hand specialist
Although a referral to a hand specialist may be appropriate in some cases, it is not the immediate action needed to assist the patient. Initial management can often be done with conservative measures like a splint before considering specialist intervention.
C) Thumb spica splint
This option is correct as a thumb spica splint effectively stabilizes the wrist and thumb, helping to relieve pressure on the median nerve. It is a common first-line treatment for carpal tunnel syndrome and is appropriate given the patient's symptoms.
D) Cortisone injections
Cortisone injections may provide relief for inflammation but are generally not the first step in treatment. They are typically considered if conservative measures, like splinting, fail to improve symptoms.
Conclusion
The thumb spica splint is the most suitable initial intervention for the patient’s symptoms, as it directly addresses the potential cause of the weakness and numbness by providing necessary support. Other options either do not address the root cause effectively or are not considered immediate interventions.
