A client who works at a computer most of the working day comes to the clinic reporting pain in both hands that causes the client to wake during the night. Which action should the nurse implement to assess for carpal tunnel syndrome?

Choice A reason: Preparing the prescribed dose of rapid-acting insulin from the sliding scale instructions is not appropriate when the client's blood glucose level is low (56 mg/dL). Administering insulin at this point could further lower the blood glucose level, potentially leading to severe hypoglycemia. The priority is to raise the client's blood glucose level to a safe range.

Choice B reason: Giving the client six ounces of non-diet carbonated soda and instructing the client to drink it entirely is the correct first intervention. The client’s blood glucose level is significantly below the normal reference range (hypoglycemia). Administering a fast-acting carbohydrate, such as non-diet soda, helps to quickly increase the blood glucose level to a safer range. This intervention addresses the immediate need to correct the hypoglycemia and prevent potential complications such as confusion, seizures, or loss of consciousness.

Choice C reason: Collecting a blood specimen by venipuncture to send to the laboratory for serum glucose analysis is not the first intervention to implement. While laboratory confirmation of blood glucose levels can be important, the immediate priority is to treat the hypoglycemia. Delaying treatment to collect a laboratory specimen could result in worsening of the client's condition. Immediate administration of a fast-acting carbohydrate should be prioritized.

Choice D reason: Documenting the glucose reading in the electronic medical record (EMR) is important but not the first priority. While accurate documentation is necessary for ongoing care, the immediate intervention should focus on treating the hypoglycemia. Once the client's blood glucose level has been stabilized, the nurse can then document the reading and subsequent interventions in the EMR.

Choice A reason: Thick skin plaques topped by silvery white scales are characteristic findings in psoriasis vulgaris itself and do not indicate overexposure to PUVA treatment. These plaques are a result of rapid skin cell turnover and are typically the target of treatment, not a side effect of overexposure.

Choice B reason: The requirement for sunglasses because sunlight hurts the eyes is not a specific indication of overexposure to PUVA treatment. While PUVA therapy can increase sensitivity to light, the use of sunglasses is a preventive measure and does not necessarily indicate overexposure.

Choice C reason: Brown, rough, greasy, wart-like papules on the face suggest the presence of seborrheic keratosis or another benign skin condition, not overexposure to PUVA treatment. These lesions are unrelated to the therapy and do not serve as an indicator of overexposure.

Choice D reason: Tenderness upon palpation and generalized erythema are signs of overexposure to PUVA treatment. Overexposure can lead to phototoxic reactions, resulting in skin irritation, redness, and tenderness. These symptoms indicate that the client has received too much UV radiation during the treatment, leading to an adverse reaction.
