A pregnant client in her second trimester has a hemoglobin level of 11 g/dL. The nurse interprets this as indicating
Hemodilution of pregnancy
A multiple gestation pregnancy
Greater-than-expected weight gain
Iron-deficiency anemia
The Correct Answer is A
Choice A: Hemodilution of pregnancy is a normal physiological phenomenon that occurs when the plasma volume increases more than the red blood cell mass, resulting in a lower hemoglobin concentration. The normal hemoglobin range for pregnant women in the second trimester is 10.5 to 14 g/dL.
Choice B: A multiple gestation pregnancy may cause a higher hemoglobin level due to increased erythropoietin production by the placenta. The normal hemoglobin range for pregnant women with twins in the second trimester is 12 to 16 g/dL.
Choice C: Greater-than-expected weight gain is not related to hemoglobin level. Weight gain during pregnancy depends on various factors such as pre-pregnancy weight, nutrition, activity level, and fetal growth.
Choice D: Iron-deficiency anemia is a condition where the hemoglobin level is below the normal range due to inadequate iron intake or absorption, blood loss, or increased iron demand. The signs and symptoms of iron-deficiency anemia include fatigue, pallor, weakness, shortness of breath, and pica.

Correct Answer is ["31"]
Explanation
The correct answer is 31 gtts/min. To calculate the infusion rate, the nurse should use the following formula:
Infusion rate (gtts/min) = Volume (mL) x Drop factor (gtts/mL) / Time (min)
Plugging in the given values, we get:
Infusion rate (gtts/min) = 1000 mL x 15 gtts/mL / 480 min
Infusion rate (gtts/min) = 31.25 gtts/min
Rounding to the nearest whole number, we get 31 gtts/min.
Correct Answer is D
Explanation
Choice A Reason: This is incorrect because ferrous sulfate is an iron supplement that is used to treat or prevent iron-deficiency anemia. It has no effect on magnesium sulfate, which is a medication that lowers blood pressure and prevents seizures in severe preeclampsia.
Choice B Reason: This is incorrect because potassium chloride is an electrolyte supplement that is used to treat or prevent low levels of potassium in the blood. It has no effect on magnesium sulfate, which can cause hypermagnesemia, or high levels of magnesium in the blood.
Choice C Reason: This is incorrect because calcium carbonate is an antacid that is used to treat or prevent heartburn, indigestion, or calcium deficiency. It has no effect on magnesium sulfate, which can cause hypocalcemia, or low levels of calcium in the blood.
Choice D Reason: This is correct because calcium gluconate is an antidote that is used to treat magnesium toxicity, which can occur when magnesium sulfate is given in high doses or for prolonged periods. Calcium gluconate reverses the effects of magnesium sulfate on the neuromuscular and cardiovascular systems, such as muscle weakness, respiratory depression, cardiac arrhythmias, or cardiac arrest.
