A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the client's daily warfarin.
Which of the following laboratory tests should the nurse plan to report to obtain the prescription for the warfarin?

Choice A rationale: Evaluating the fetal heart rate tracing is the most critical action in this scenario. The client is at 31 weeks of gestation and reports decreased fetal movement, which could indicate fetal distress. The nurse should first assess the fetal heart rate tracing to ensure the fetus is not in distress. Normal fetal heart rate is between 110 and 160 beats per minute.

Choice B rationale: Obtaining a 24-hour urine collection is important for assessing proteinuria, a sign of preeclampsia, but it is not the most immediate concern. The nurse can initiate this after ensuring the fetus is not in distress.

Choice C rationale: Administering acetaminophen PO (by mouth) can help relieve the client’s headache, but it is not the most immediate concern. The nurse can administer this medication after ensuring the fetus is not in distress and initiating other prescribed treatments.

Choice D rationale: Administering magnesium sulfate IV (intravenously) can prevent seizures in clients with preeclampsia. However, before administering this medication, the nurse should ensure that the fetus is not in distress.

Choice E rationale: Administering betamethasone IM (intramuscularly) can help accelerate fetal lung maturity in case of preterm labor. However, before administering this medication, the nurse should ensure that the fetus is not in distress.

Choice F rationale: Inserting an indwelling urinary catheter can help monitor urine output, which is important for clients receiving magnesium sulfate because oliguria can be a sign of magnesium toxicity. However, before inserting the catheter, the nurse should ensure that the fetus is not in distress.

Explanation: Sweet potato is a food that is high in potassium, which is an electrolyte that regulates fluid balance, nerve impulses, and muscle contractions in the body. A medium- sized sweet potato contains about 541 mg of potassium, which is more than 10% of the recommended daily intake for adults. Baked chicken breast, wheat bread, and canned green beans are foods that are low or moderate in potassium, containing less than 300 mg per serving.
