A nurse is caring for a client who is taking allopurinol. The nurse should monitor which of the following laboratory findings to determine the effectiveness of the medication?

A. The preschooler wears a medical identification bracelet: Wearing a medical ID bracelet is a safety measure that allows caregivers and healthcare professionals to respond appropriately during a seizure. No modification is needed for this practice.

B. The preschooler takes tub baths independently: Independent tub bathing poses a significant risk of injury or drowning if a seizure occurs during bathing. The nurse should recommend modifications, such as supervised showers or sponge baths, to ensure the child’s safety.

C. The preschooler sleeps in a bed with side rails: Using side rails can prevent falls from bed during a seizure. This is an appropriate safety measure and does not require modification.

D. The preschooler's mattress is waterproof: A waterproof mattress protects against injury from incontinence or vomiting during a seizure and is a suitable precaution that does not require modification

A. Levothyroxine for hypothyroidism: Levothyroxine is a thyroid hormone replacement that is considered safe in pregnancy. Proper management of maternal hypothyroidism is essential for fetal neurodevelopment, and it does not pose teratogenic risk.

B. Phenytoin for seizure disorder: Phenytoin is an antiepileptic drug associated with fetal hydantoin syndrome, which can cause congenital malformations such as cleft lip, cardiac defects, and skeletal abnormalities. It carries a known risk for teratogenic effects, requiring careful monitoring and potential consideration of alternative therapies.

C. Magnesium oxide for constipation: Magnesium oxide is generally safe for use during pregnancy for the treatment of constipation. It does not have teratogenic effects and is considered appropriate for maternal use when needed.

D. Ferrous sulfate for chronic anemia: Iron supplementation is essential in pregnancy to prevent maternal anemia and support fetal growth. Ferrous sulfate is safe and does not cause congenital malformations, making it an appropriate therapy during pregnancy.
