A nurse is administering a unit of RBC 350 mL over 3 hr to a client who has anemia. The nurse should set the IV pump to deliver how many mL/hr?

(Round the answer to the nearest whole number)

Choice A reason: Polyuria is not an expected finding in a client with severe preeclampsia, as it can indicate dehydration, diabetes, or renal impairment. A client with severe preeclampsia may have oliguria, which is a urine output of less than 500 mL in 24 hours, due to the decreased renal perfusion and function.

Choice B reason: Report of headache is an expected finding in a client with severe preeclampsia, as it can indicate increased intracranial pressure, cerebral edema, or vasospasm. A client with severe preeclampsia may also have other neurological symptoms, such as blurred vision, scotoma, photophobia, or hyperreflexia.

Choice C reason: Tachycardia is not an expected finding in a client with severe preeclampsia, as it can indicate dehydration, infection, anxiety, or fetal distress. A client with severe preeclampsia may have bradycardia, which is a heart rate of less than 60 beats per minute, due to the increased vagal tone and blood pressure.

Choice D reason: Absence of clonus is not an expected finding in a client with severe preeclampsia, as it can indicate normal or decreased neuromuscular irritability. A client with severe preeclampsia may have positive clonus, which is a rhythmic jerking of the foot when the ankle is dorsiflexed, due to the increased reflex excitability and hyperactivity.

Choice A reason: This statement is incorrect, as it is not the definition of polyhydramnios, but rather a possible cause of it. Polyhydramnios is a condition where the amniotic fluid volume exceeds 2,000 mL at term, or the amniotic fluid index (AFI) is greater than 25 cm. Polyhydramnios can occur in multiple pregnancies, as the fetuses produce more urine and fluid than a single fetus.

Choice B reason: This statement is incorrect, as it is not the definition of polyhydramnios, but rather a possible complication of it. Polyhydramnios can cause fetal anomalies, such as esophageal atresia, anencephaly, or neural tube defects, which impair the swallowing or absorption of the amniotic fluid. Polyhydramnios can also cause fetal growth restriction or distress, as the excess fluid can compress the umbilical cord or the placenta, and reduce the blood flow and oxygen delivery to the fetus.

Choice C reason: This statement is correct, as it is the definition of polyhydramnios, which is a condition where the amniotic fluid volume exceeds 2,000 mL at term, or the amniotic fluid index (AFI) is greater than 25 cm. Polyhydramnios can be diagnosed by ultrasound, and it can cause maternal and fetal complications, such as preterm labor, premature rupture of membranes, placental abruption, or cord prolapse.

Choice D reason: This statement is incorrect, as it is not the definition of polyhydramnios, but rather a marker of fetal anomalies. Alpha-fetoprotein (AFP) is a protein that is produced by the fetus, and it can be measured in the maternal serum or the amniotic fluid. An elevated level of AFP in the amniotic fluid can indicate fetal anomalies, such as neural tube defects, abdominal wall defects, or renal anomalies, which can cause polyhydramnios.
