The physician prescribes prostaglandin (PGE2) gel for a patient being admitted for induction of labor.
Which finding would best indicate that the prostaglandin gel is effective?
The patient’s cervix is dilated.
The patient’s uterine contraction pattern is enhanced.
The patient’s cervix is softened.
The patient’s uterus is softened.
The Correct Answer is B
The correct answer is choice B. The patient’s uterine contraction pattern is enhanced. Prostaglandin E2 gel is used to induce labor by ripening and dilating the cervix and stimulating uterine contractions. The effectiveness of the gel can be measured by the frequency, duration and intensity of the contractions.
A stronger and more regular contraction pattern indicates that the gel is working and labor is progressing.
Choice A is wrong because cervical dilation is not the only indicator of labor induction. Cervical dilation can occur without contractions or with weak and irregular contractions, which means that labor is not established yet.
Choice C is wrong because cervical softening (or effacement) is a prerequisite for cervical dilation, but it does not necessarily mean that labor has started. Cervical softening can occur weeks before labor or even during pregnancy.
Choice D is wrong because uterine softening (or relaxation) is the opposite of what prostaglandin E2 gel is supposed to do. Uterine softening reduces the contractility and tone of the uterus, which can lead to prolonged labor or fetal distress.

Correct Answer is D
Explanation
The correct answer is choice D. Orange juice.This is because orange juice is rich in vitamin C, which enhances the absorption of iron from ferrous sulfate tablets.Vitamin C helps reduce iron to its ferrous form, which is more readily absorbed by the intestinal cells.
Choice A is wrong because milk contains calcium, which inhibits iron absorption by forming insoluble complexes with iron.Choice
B is wrong because tea contains tannins, which are polyphenols that bind to iron and decrease its bioavailability.Choice C is wrong because water does not have any effect on iron absorption, neither enhancing nor inhibiting it.
Normal ranges for serum iron are 50-170 mcg/dL for men and 40-150 mcg/dL for women.Normal ranges for hemoglobin are 13.5-17.5 g/dL for men and 12-15.5 g/dL for women.
Correct Answer is D
Explanation
The correct answer is choice D. The increase in maternal blood volume is greater than the increase in maternal red blood cells.
This means that the concentration of hemoglobin and hematocrit in the blood is diluted by the extra fluid.
This is a normal physiological adaptation to pregnancy and does not indicate iron deficiency anemia.
Choice A is wrong because placental hormones do not chelate maternal iron.
Chelation is a process of binding metal ions to organic molecules, which is not relevant to this question.
Choice B is wrong because fetal demand for iron is not greater than maternal intake.
The mother can meet the iron needs of the fetus by increasing her dietary intake and taking iron supplements.
Choice C is wrong because maternal intestinal absorption of iron is not decreased during pregnancy.
In fact, it may be increased due to higher levels of estrogen and progesterone.
