Before administering the initial dose of sumatriptan succinate to a client with a migraine headache, it is most important to determine if the client's hi’tory includes which problem?

1. pH: Calcium acetate is not directly related to changes in blood pH. Therefore, monitoring pH levels would not indicate the effectiveness of the medication for CKD.

B) Calcium: Calcium levels may be affected by calcium acetate, but the primary goal of using calcium acetate in CKD is to reduce phosphate levels, not calcium levels. Therefore, monitoring calcium levels would not directly indicate the effectiveness of the medication.

C) Potassium: Calcium acetate is not typically used to affect potassium levels. Monitoring potassium levels would not indicate the effectiveness of calcium acetate for CKD.

D) Phosphate: This is the correct answer. Calcium acetate is a phosphate binder commonly used in CKD to help lower elevated phosphate levels. A decrease in phosphate levels in the blood would indicate that the medication is having the desired effect in controlling phosphate levels, which is important in managing CKD and preventing complications associated with hyperphosphatemia. Therefore, monitoring phosphate levels is essential to assess the effectiveness of calcium acetate therapy in CKD.

A) Collecting a capillary glucose level is not indicated in response to hand tremors reported by a client taking pregabalin for fibromyalgia. Hand tremors are not typically associated with hypoglycemia, which is what capillary glucose levels assess. Therefore, this action does not directly address the reported symptom.

B) Notifying the healthcare provider is the most appropriate action in response to the client’s report of experiencing tremors while taking pregabalin. Hand tremors can be a potential adverse effect of pregabalin, and the healthcare provider should be informed to assess the severity of the symptom, consider alternative medications or dosage adjustments, and determine the need for further evaluation or intervention.

C) Obtaining orthostatic blood pressure readings is not indicated in response to hand tremors reported by a client taking pregabalin for fibromyalgia. Orthostatic blood pressure readings assess for changes in blood pressure upon position changes (e.g., from lying down to standing up) and are not directly relevant to the reported symptom of tremors.

D) Administering a PRN dose of an antianxiety drug is not the first-line intervention for hand tremors reported by a client taking pregabalin. While antianxiety medications may help alleviate symptoms of anxiety, they do not address the underlying cause of the tremors. Additionally, the client’s tremors may not necessarily be related to anxiety. Therefore, the nurse should prioritize notifying the healthcare provider for further assessment and management of the reported symptom.
