The nurse is preparing to assist with blood collection on a newly admitted patient who has been taking phenytoin for several years.
The provider has ordered a complete blood count and liver function tests.
Which other blood test will the nurse discuss with the provider?
Coagulation studies.
Serum electrolytes.
Renal function tests.
Blood glucose.
The Correct Answer is D
Choice A rationale
Coagulation studies assess the blood's ability to clot and are not directly related to the monitoring of phenytoin therapy. These tests are more relevant for patients with bleeding disorders or those on anticoagulant therapy.
Choice B rationale
Serum electrolytes, including levels of sodium, potassium, and calcium, are important for overall health but are not specifically indicative of phenytoin levels. Phenytoin may affect calcium metabolism, but it is not the primary focus for routine monitoring.
Choice C rationale
Renal function tests are crucial for assessing kidney function but do not directly monitor phenytoin therapy. Phenytoin is primarily metabolized in the liver, making liver function tests more relevant.
Choice D rationale
Blood glucose levels should be monitored in patients taking phenytoin as the drug can cause alterations in blood glucose levels. Both hypoglycemia and hyperglycemia have been reported, so it is important to check glucose levels to ensure they remain within a normal range.

Correct Answer is C
Explanation
Choice A rationale
Poor self-care is not directly associated with reddened, bleeding gums in this context.
Choice B rationale
While aspirin can cause bleeding issues, the context here is related to seizure disorder and phenytoin.
Choice C rationale
Phenytoin, an anticonvulsant used to manage seizures, can cause gingival hyperplasia, leading to reddened and bleeding gums.
Choice D rationale
Hepatotoxicity is related to liver damage and does not present with reddened, bleeding gums.
Correct Answer is B
Explanation
Choice A rationale
Giving ipecac with a glass of milk is not recommended. Milk can delay the emetic effect of ipecac and potentially interfere with its ability to induce vomiting. It is essential to follow proper guidelines for ipecac administration to ensure its effectiveness and safety.
Choice B rationale
Consulting a poison control center before administering ipecac is crucial. Poison control experts can provide specific recommendations based on the type and amount of substance ingested. Not all poisoning cases require ipecac, and its inappropriate use can cause more harm than good.
Choice C rationale
Ipecac fluid extract is significantly more potent than ipecac syrup and is not recommended for home use. The syrup form is standardized for safe administration in inducing vomiting, whereas the fluid extract can cause severe toxicity if used incorrectly.
Choice D rationale
The emetic effect of ipecac is not immediate. It typically takes about 20 to 30 minutes for vomiting to occur after administration. Providing patients and caregivers with accurate information about the onset of action is essential to avoid unnecessary anxiety.
