To detect common untoward effects of phenytoin, the nurse should assess a client with a seizure disorder for which sign or symptom?

A) Avoid the intake of dairy products while using the medication: There is no specific requirement to avoid dairy products when using bulk-forming laxatives. The primary concern with bulk-forming laxatives is to ensure they are taken with adequate fluids.
B) Take the medication one hour after meals and other medications: Bulk-forming laxatives should be taken with a meal or at a different time from other medications to prevent interactions, but the key aspect is to follow the medication with sufficient fluids rather than timing relative to meals.
C) Remain upright for thirty minutes following drug administration: While remaining upright can help prevent potential esophageal irritation, it is not the primary instruction for bulk-forming laxatives. The more critical instruction is related to fluid intake to ensure effectiveness and prevent complications.
D) Follow medication administration with an additional glass of water: Bulk-forming laxatives require adequate fluid intake to function properly. Following the medication with an additional glass of water helps the laxative form a gel-like substance in the intestines, which aids in bowel movement and prevents potential complications like obstruction.

A) Hypertension: Phenytoin is primarily used to manage seizures, and hypertension is not a common side effect associated with its use. While monitoring blood pressure is important for overall health, it is not specifically indicated for detecting common side effects of phenytoin.
B) Peripheral edema: Peripheral edema is not a typical side effect of phenytoin. Common side effects are usually related to oral health and skin changes rather than fluid retention or swelling in the extremities.
C) Hematuria: Hematuria, or blood in the urine, is not commonly associated with phenytoin use. This side effect is more relevant to other medications or conditions, and while monitoring for overall health changes is important, it is not a primary concern with phenytoin.
D) Gingival hyperplasia: Phenytoin is well-known for causing gingival hyperplasia, which is the overgrowth of gum tissue. This is a common and notable side effect of long-term phenytoin use, making it important for the nurse to assess for this symptom in clients receiving the medication.
