The nursing instructor is preparing to illustrate the various changes between the nonpregnant and pregnant female bodies.
The instructor should point out that the blood volume in the pregnant woman can increase by what percentage?
20% to 25%.
40% to 45%.
50% to 55%.
30% to 35%.
The Correct Answer is B
Blood volume increases significantly within the first few weeks of gestation and increases progressively throughout the pregnancy.
The total blood volume increase varies from 20% to 100% above prepregnancy levels, usually close to 45%1.
Choice A is incorrect because the increase is usually close to 45%, not 20% to 25%.
Choice C is incorrect because the increase is usually close to 45%, not 50% to 55%.
Choice D is incorrect because the increase is usually close to 45%, not 30% to 35%.

Correct Answer is C
Explanation
This is an antibiotic ointment that is applied to the eyes of newborns to prevent ophthalmia neonatorum, a serious eye infection caused by gonorrhea.
Ophthalmia neonatorum can cause blindness if left untreated and can occur even if the mother does not have symptoms of gonorrhea.
Erythromycin is the only drug approved by the FDA for this purpose and is mandated in most states.
Choice A.
Nystatin is incorrect, as this is an antifungal medication that is used to treat oral thrush or diaper rash in newborns, not eye infections.
Choice B.
Ceftriaxone is incorrect, as this is an antibiotic injection that is used to treat systemic gonorrhea infections in adults or newborns, not eye infections.
Choice D.
Ofloxacin is incorrect, as this is an antibiotic eye drop that is used to treat bacterial conjunctivitis in older children and adults, not ophthalmia neonatorum in newborns.
Therefore, choice C is the best answer to this question.
