According to a study in the year 2013 by Fellman, if a woman is a twin, if her mother was a twin, or if she has previously borne twins, then:
- A. she will bear only monozygotic (MZ) twins.
- B. the chances of her becoming pregnant decrease.
- C. she is likely to be a healthy mother.
- D. the chances rise that she will bear twins.
Correct Answer: D
Rationale: According to the study, the chances of a woman bearing twins increase if she is a twin herself, if her mother was a twin, or if she has previously borne twins. Therefore, the correct answer is D. Choice A is incorrect because the study does not specify that she will bear only monozygotic twins. Choice B is incorrect as the study does not mention any decrease in the chances of becoming pregnant. Choice C is incorrect because the study does not provide information about the woman's health status, focusing instead on the likelihood of bearing twins.

A client who is pregnant and follows a vegan diet asks a nurse for guidance on foods high in calcium. Which of the following foods has the highest amount of calcium?
- A. ½ cup cubed avocado
- B. 1 large banana
- C. 1 medium potato
- D. 1 cup cooked broccoli
Correct Answer: D
Rationale: The correct answer is D: 1 cup of cooked broccoli. Broccoli is an excellent source of calcium, making it a suitable choice for a vegan diet. Avocado (Choice A), banana (Choice B), and potato (Choice C) are not significant sources of calcium compared to broccoli. Avocado and banana are primarily sources of other nutrients like healthy fats and potassium, respectively. Potato is a good source of vitamin C and potassium but not calcium. Therefore, for a pregnant client following a vegan diet and seeking calcium-rich foods, cooked broccoli is the most appropriate choice.
A newborn is being assessed by a nurse who was born post-term. Which of the following findings should the nurse expect?
- A. Nails extending over tips of fingers
- B. Large deposits of subcutaneous fat
- C. Pale, translucent skin
- D. Thin covering of fine hair on shoulders and back
Correct Answer: A
Rationale: Post-term newborns often have longer nails that extend over the tips of their fingers due to the extended gestation period. This occurs because the baby continues to grow in utero past the typical 40 weeks of gestation. Choices B, C, and D are incorrect as large deposits of subcutaneous fat, pale translucent skin, and a thin covering of fine hair on shoulders and back are not typically associated with post-term newborns. Longer nails are a common finding in post-term newborns due to the prolonged time spent in the womb, allowing for more nail growth compared to infants born at term.
What information should the nurse include when teaching a client at 41 weeks of gestation about a non-stress test?
- A. This test will confirm fetal lung maturity.
- B. This test will determine the adequacy of placental perfusion.
- C. This test will detect fetal infection.
- D. This test will predict maternal readiness for labor.
Correct Answer: B
Rationale: The correct answer is B: 'This test will determine the adequacy of placental perfusion.' The non-stress test is used to assess fetal well-being by monitoring the fetal heart rate in response to its own movements. It helps determine if the fetus is receiving enough oxygen and nutrients through placental perfusion. Choice A is incorrect because confirming fetal lung maturity is typically determined through tests like amniocentesis, not the non-stress test. Choice C is incorrect because detecting fetal infection is not the primary purpose of a non-stress test. Choice D is incorrect because predicting maternal readiness for labor is not the purpose of the non-stress test; it focuses on fetal well-being.
Rico is a man who has enlarged breasts and suffers from mild mental retardation. He has a problem learning languages, and his body produces less of the male sex hormone testosterone than normal males. Rico is most likely suffering from:
- A. Klinefelter syndrome.
- B. Tay-Sachs disease.
- C. Turner syndrome.
- D. Down syndrome.
Correct Answer: A
Rationale: Rico's symptoms align with Klinefelter syndrome, which is characterized by an extra X chromosome in males (XXY). Enlarged breasts (gynecomastia), mild mental retardation, learning difficulties, and reduced testosterone production are common features of Klinefelter syndrome. Choice B, Tay-Sachs disease, is a genetic disorder that affects the nervous system and is not associated with the symptoms described. Choice C, Turner syndrome, occurs in females with a missing or partially missing X chromosome and does not fit Rico's profile. Choice D, Down syndrome, is caused by an extra copy of chromosome 21 and typically does not present with the symptoms mentioned for Rico.
At 31 weeks gestation, a client with a fundal height measurement of 25 cm is scheduled for a series of ultrasounds to be performed every two weeks. Which explanation should the nurse provide?
- A. Assessment for congenital anomalies
- B. Recalculation of gestational age
- C. Evaluation of fetal growth
- D. Determination of fetal presentation
Correct Answer: C
Rationale: The correct answer is C: 'Evaluation of fetal growth.' A fundal height measurement smaller than expected may indicate intrauterine growth restriction (IUGR), requiring serial ultrasounds to monitor fetal growth. Assessing for congenital anomalies (choice A) is usually done through detailed anatomy scans earlier in pregnancy. Recalculating gestational age (choice B) is typically unnecessary at this stage unless there are concerns about accuracy. Determining fetal presentation (choice D) is usually done closer to term to plan for the mode of delivery.
