What is the responsibility of the nurse related to the patient’s drug therapy? Select all that apply.

Choice A rationale

Evidence of human fetal risk would categorize the drug as Category D or X, not Category B.

Choice B rationale

This statement aligns more with Category C drugs, where animal studies show adverse effects, but not Category B.

Choice C rationale

This describes Category A drugs, not Category B.

Choice D rationale

Category B drugs have shown no risk in animal studies but lack adequate human studies, fitting this description.

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.
