The maternity nurse understands that vascular volume increases 40% to 45% during pregnancy to:
compensate for decreased renal plasma flow.
prevent maternal and fetal dehydration.
provide adequate perfusion of the placenta.
eliminate metabolic wastes of the mother.
The Correct Answer is C
Choice A reason: Vascular volume increases during pregnancy to meet the increased oxygen and nutrient demands of the fetus, not to compensate for decreased renal plasma flow. In fact, renal plasma flow increases by 50% to 80% during pregnancy to facilitate the excretion of metabolic wastes.
Choice B reason: Vascular volume increases during pregnancy to ensure adequate blood supply to the uterus and other organs, not to prevent maternal and fetal dehydration. Dehydration can occur due to vomiting, diarrhea, or inadequate fluid intake, and it can be prevented by drinking enough fluids and replacing electrolytes.
Choice C reason: Vascular volume increases during pregnancy to provide adequate perfusion of the placenta, which is the main organ of gas exchange and nutrient delivery for the fetus. The placenta receives about 10% of the maternal cardiac output at term.
Choice D reason: Vascular volume increases during pregnancy to support the growth and development of the fetus and the maternal tissues, not to eliminate metabolic wastes of the mother. Metabolic wastes are eliminated by the kidneys, lungs, skin, and gastrointestinal tract.

Correct Answer is B
Explanation
Choice A reason: Pointing out that inappropriate sexual behavior caused the infection is not helpful, as it may make the woman feel guilty, ashamed, or defensive. The nurse should avoid blaming or judging the woman and focus on providing education and support.
Choice B reason:Positioning the patient in asemi-Fowler position(head of the bed elevated 30–45 degrees) helps promote drainage of pelvic exudate and reduces the risk of abscess formation or further spread of infection. This is a key nursing intervention for patients withacute pelvic inflammatory disease (PID).
Choice C reason: Telling her that antibiotics need to be taken until pelvic pain is relieved is incorrect, as it may lead to incomplete treatment and recurrence of the infection. The nurse should instruct the woman to take the full course of antibiotics as prescribed, regardless of the symptoms.
Choice D reason:While infertility is apotential complicationof PID, it is not a guaranteed outcome. The nurse should provideaccurate informationabout risks but avoid causing unnecessary alarm. The focus should be onprompt treatment and prevention of complications.
Correct Answer is A
Explanation
The correct answer is A. You may find that you need to modify your exercise to walking later in your pregnancy, around the seventh month.
Choice A reason: This is the best advice for the woman, as it acknowledges that jogging is safe and beneficial in early pregnancy, but also informs her that she may need to adjust her exercise intensity and duration as her pregnancy progresses. Walking is a low-impact aerobic activity that can be done throughout pregnancy, as long as there are no complications or contraindications. Walking can help maintain cardiovascular fitness, prevent excessive weight gain, and reduce the risk of gestational diabetes and preeclampsia.
Choice B reason: This is not a good advice for the woman, as it implies that jogging is harmful for her joints and that she should stop it immediately. Jogging is not necessarily bad for the joints, as long as the woman wears appropriate shoes, avoids uneven surfaces, and listens to her body. Jogging can also provide many health benefits for the woman and the fetus, such as improved mood, increased energy, and reduced stress².
Choice C reason: This is a false and alarming statement that may discourage the woman from exercising at all. Exercise during pregnancy is not dangerous for the fetus, unless there are specific medical conditions or complications that prevent it. Exercise during pregnancy can actually improve the fetal growth, development, and oxygenation, as well as reduce the risk of preterm birth and low birth weight.
Choice D reason: This is an unrealistic and misleading statement that may cause the woman to overexert herself or ignore the signs of discomfort or fatigue. Exercise during pregnancy may need to be modified according to the woman's changing needs, abilities, and preferences. Some factors that may affect the type, frequency, intensity, and duration of exercise during pregnancy include the trimester, the fetal position, the maternal weight, the environmental temperature, and the presence of any symptoms or complications.
