A nurse in a clinic is caring for an adolescent client who is at 24 weeks of gestation and showing signs of preeclampsia. Which of the following findings should the nurse expect?

Rationale:

A. Consult the pharmacist about potential interactions between the client's regular medications and warfarin: Warfarin has numerous drug interactions that can increase bleeding risk or reduce effectiveness. Consulting the pharmacist ensures a thorough review of the client’s medication list for potential harmful interactions before discharge.

B. Tell the client they can continue to drink cranberry juice while taking warfarin: Cranberry juice can potentiate the effects of warfarin and increase bleeding risk by interfering with its metabolism. Clients should be advised to limit or avoid cranberry products.

C. Recommend the client take warfarin at the same time as other medications: Warfarin should be taken at the same time each day, but taking it with other medications may cause interactions. The timing should consider spacing it from medications that might interfere with absorption or potency.

D. Advise the client that over-the-counter medications remain safe to consume as needed: Many OTC medications, especially NSAIDs, can increase bleeding risk when combined with warfarin. Clients need to check with a healthcare provider before taking any new OTC drugs.

Rationale:

A. Prepare an IV bolus of dextrose 5% in water: Dextrose in water does not reverse magnesium toxicity. It may be used as a fluid carrier but does not serve as an antidote or address the neuromuscular and cardiac effects of excessive magnesium.

B. Administer calcium gluconate IV: Calcium gluconate is the antidote for magnesium sulfate toxicity. It helps reverse respiratory depression, muscle weakness, and cardiac conduction delays caused by high magnesium levels, making it the immediate intervention.

C. Position the client supine: The supine position can worsen hypotension by decreasing venous return, especially in pregnant clients. Left lateral positioning is generally preferred to improve circulation to vital organs and the fetus.

D. Administer methylergonovine IM: Methylergonovine is used to treat postpartum hemorrhage, but it is contraindicated in clients with hypertension or preeclampsia due to its vasoconstrictive effects. It does not treat magnesium toxicity and could increase blood pressure dangerously.
