Which FHR finding is the most concerning to the nurse providing care to a laboring client?
- A. Accelerations with fetal movement.
- B. Early decelerations.
- C. Average FHR of 126 beats per minute.
- D. Late decelerations.
Correct Answer: D
Rationale: Late decelerations are caused by uteroplacental insufficiency, resulting in fetal hypoxemia. They are considered ominous if persistent, indicating compromised oxygen supply to the fetus. Accelerations with fetal movement (Choice A) are reassuring signs of fetal well-being. Early decelerations (Choice B) are typically benign, associated with head compression during contractions. An average FHR of 126 beats per minute (Choice C) falls within the normal range for fetal heart rate and is not concerning. Therefore, the most concerning FHR finding in a laboring client is late decelerations (Choice D).

A primigravida at 36 weeks gestation who is RH-negative experienced abdominal trauma in a motor vehicle collision. Which assessment finding is most important for the nurse to report to the healthcare provider?
- A. Fetal heart rate at 162 beats per minute
- B. Mild contractions every 10 minutes
- C. Trace of protein in the urine
- D. Positive fetal hemoglobin testing
Correct Answer: D
Rationale: The correct answer is 'Positive fetal hemoglobin testing' (D). Positive fetal hemoglobin testing (Kleihauer-Betke test) indicates fetal-maternal hemorrhage, which is critical in an RH-negative mother due to the risk of isoimmunization. This condition can lead to sensitization of the mother's immune system against fetal blood cells, potentially causing hemolytic disease of the newborn in subsequent pregnancies. Reporting this finding promptly is crucial for appropriate management and interventions. Choices A, B, and C are not as critical in this scenario. While monitoring fetal heart rate and contractions is important, the detection of fetal-maternal hemorrhage takes precedence due to the serious implications it poses for the current and future pregnancies of an RH-negative mother.
What is the process in which the double helix of deoxyribonucleic acid (DNA) duplicates?
- A. Amniocentesis
- B. Mitosis
- C. Meiosis
- D. Mutation
Correct Answer: B
Rationale: Mitosis is the correct answer because it is the process of cell division in which a cell duplicates its DNA and divides into two identical daughter cells. During mitosis, the DNA is replicated, and each daughter cell receives an identical copy of the genetic material. Amniocentesis is a medical procedure to collect amniotic fluid for prenatal genetic testing and is not related to DNA duplication. Meiosis is a type of cell division that produces gametes with half the genetic material of the parent cell, leading to genetic diversity. Mutation is a permanent alteration in the DNA sequence that can lead to genetic variations but is not the process of DNA duplication.
A client who is at 24 weeks of gestation is receiving teaching about expected changes during pregnancy. Which of the following information should the nurse include?
- A. Your stomach will empty rapidly
- B. You should expect your uterus to double in size
- C. You should anticipate nasal stuffiness
- D. Your nipples will become lighter in color
Correct Answer: C
Rationale: Nasal stuffiness is a common symptom during pregnancy due to increased blood flow and hormonal changes. This symptom is caused by the increased blood volume and hormonal changes that lead to swelling of the nasal passages. Choices A, B, and D are incorrect. Stomach emptying rate does not significantly change during pregnancy; the uterus does not double in size at 24 weeks but rather grows steadily, and nipples typically darken in color due to increased pigmentation.
Are sperm much larger than ova?
- A. TRUE
- B. FALSE
- C. Sometimes
- D. Always
Correct Answer: B
Rationale: The correct answer is B: FALSE. Ova, also known as eggs, are actually the largest cells in the human body, while sperm are significantly smaller. This size difference is due to the different functions of the two gametes. Sperm are specialized for motility to reach and fertilize the egg, while ova contain nutrients and cellular machinery needed for fertilization and early embryonic development. Choices A, C, and D are incorrect because sperm are not larger than ova; they are much smaller in size.
During the client's initial prenatal visit, which of the following would indicate a need for further assessment?
- A. History of diabetes for 6 years.
- B. Exercises three times a week.
- C. Occasional use of over-the-counter pain relievers.
- D. Maternal age 30 years.
Correct Answer: A
Rationale: A history of diabetes for 6 years indicates a pre-existing medical condition that can significantly impact both the mother and the developing fetus during pregnancy. This necessitates further assessment and monitoring to manage potential complications. Regular exercise (Choice B) is generally beneficial during pregnancy and does not raise immediate concerns. Occasional use of over-the-counter pain relievers (Choice C) is common and does not necessarily indicate a need for further assessment during the initial visit. Maternal age of 30 years (Choice D) falls within the normal range for childbearing and is not a standalone factor requiring immediate further assessment.
