The nurse is reviewing a prenatal client’s record. Which history finding increases the risk for preeclampsia?
- A. Advanced maternal age.
- B. History of gestational diabetes.
- C. First pregnancy.
- D. History of anemia.
Correct Answer: C
Rationale: The correct answer is C: First pregnancy. Preeclampsia is more common in first pregnancies due to the body's lack of adaptation to the pregnancy. In subsequent pregnancies, the body has already gone through the changes necessary for pregnancy, reducing the risk. Advanced maternal age (A) and history of gestational diabetes (B) are risk factors for other pregnancy complications but not specifically preeclampsia. History of anemia (D) is not directly linked to an increased risk of preeclampsia.

If pregnancy does not occur, the corpus luteum will disintegrate and turn into what is called the?
- A. Corpus albicans
- B. Corpus callosum
- C. Corpus cavernosum
- D. Corpus allatum OB Week 1 Practice Questions
Correct Answer: A
Rationale: The correct answer is A: Corpus albicans. After ovulation, if pregnancy does not occur, the corpus luteum regresses and degenerates into the corpus albicans, which is a white scar tissue in the ovary. This process marks the end of the ovarian cycle. The other options are incorrect: B: Corpus callosum is a structure in the brain, C: Corpus cavernosum refers to erectile tissue in the penis, and D: Corpus allatum is a neuroendocrine organ in insects.
The nurse is preparing a client for a biophysical profile (BPP). What does this test evaluate?
- A. Maternal blood flow to the placenta.
- B. Fetal genetic abnormalities.
- C. Fetal well-being, including movements and amniotic fluid.
- D. Cervical dilation and effacement.
Correct Answer: C
Rationale: The correct answer is C: Fetal well-being, including movements and amniotic fluid. A Biophysical Profile evaluates the fetus' health by assessing factors like fetal movements, muscle tone, breathing movements, amniotic fluid volume, and fetal heart rate patterns. This test provides valuable information about the fetus' well-being and helps in determining the need for interventions or further monitoring.
Explanation of why the other choices are incorrect:
A: Maternal blood flow to the placenta is not evaluated by a Biophysical Profile.
B: Fetal genetic abnormalities are not assessed through a BPP; it focuses on the fetus' current well-being.
D: Cervical dilation and effacement are related to labor progress and not part of a BPP, which focuses on fetal well-being.
A client at 37 weeks' gestation reports severe itching without a rash. What condition should the nurse suspect?
- A. Preeclampsia.
- B. Cholestasis of pregnancy.
- C. Gestational diabetes.
- D. Fungal infection.
Correct Answer: B
Rationale: The correct answer is B: Cholestasis of pregnancy. Severe itching without a rash in a pregnant client at 37 weeks' gestation is concerning for cholestasis of pregnancy, a condition characterized by impaired bile flow. This can lead to elevated bile acids, causing itching. Preeclampsia (choice A) presents with hypertension and proteinuria. Gestational diabetes (choice C) manifests with high blood sugar levels. Fungal infection (choice D) typically presents with visible skin changes like a rash, which is absent in this case. In summary, cholestasis of pregnancy is the most likely explanation for severe itching in this scenario.
A new mother asks the nurse why newborns receive an injection of vit. K after delivery. What will be the best response from the nurse?
- A. Newborns are given vit K to help with the digestion to help them absorb fat soluble vitamins
- B. Newborns are given vit K and erythromycin ointment to help prevent ophthalmia neonatorum
- C. Newborns lack the intestinal flora needed to produce vit K, so it is given to prevent bleeding episodes
- D. This vitamin substitutes for vitamin C and newborns will strengthen their immune system
Correct Answer: C
Rationale: The correct answer is C. Newborns lack the intestinal flora needed to produce vitamin K, so it is given to prevent bleeding episodes. Vitamin K is essential for blood clotting, and newborns have lower levels at birth. Without enough vitamin K, newborns are at risk of bleeding issues. Giving them a vitamin K injection helps prevent potential bleeding disorders.
Choice A is incorrect because vitamin K is not given for digestion or fat absorption. Choice B is incorrect as erythromycin ointment is used for preventing eye infections, not related to vitamin K injections. Choice D is incorrect as vitamin K does not substitute for vitamin C, and it is not primarily for strengthening the immune system.
The nurse is educating a client about gestational diabetes. What is the most important teaching point?
- A. Avoid all carbohydrates.
- B. Check your blood sugar only when symptomatic.
- C. Monitor blood sugar regularly as prescribed.
- D. Increase your physical activity significantly.
Correct Answer: C
Rationale: The correct answer is C: Monitor blood sugar regularly as prescribed. This is crucial in managing gestational diabetes to ensure blood sugar levels are within target range, preventing complications for both mother and baby. Regular monitoring helps track the effectiveness of treatment and dietary adjustments. Avoiding all carbohydrates (A) is not recommended as some are necessary for energy. Checking blood sugar only when symptomatic (B) is insufficient as it may miss important fluctuations. Increasing physical activity significantly (D) is beneficial but not the most important teaching point compared to consistent blood sugar monitoring.
