A woman delivers a fetal demise that has lanugo covering the entire body, nails that are present on the fingers and toes, but eyes that are still fused. Prior to the death, the mother stated that she had felt quickening. Based on this information, the nurse knows that the baby is about how many weeks’ gestation?
- A. 15 weeks.
- B. 22 weeks.
- C. 29 weeks.
- D. 36 weeks.
Correct Answer: B
Rationale: Lanugo typically appears around 16-20 weeks and covers the entire body by 22-24 weeks. Nails begin forming at around 18-20 weeks and are fully developed by 22 weeks. Fused eyelids occur up until about 24-26 weeks, after which they open. Quickening (feeling of fetal movement) usually occurs between 18-22 weeks in first-time pregnancies. Therefore, the most likely gestational age is 22 weeks.

- A. Fertilized egg has yet to implant

A nurse is caring for a patient in labor who is receiving oxytocin for induction. Which of the following is a priority assessment for the nurse?
- A. Fetal heart rate monitoring
- B. Fluid intake and output
- C. Uterine tone assessment
- D. Maternal blood pressure monitoring
Correct Answer: A
Rationale: The correct answer is A: Fetal heart rate monitoring. This is a priority assessment because oxytocin can cause uterine hyperstimulation, leading to fetal distress. Monitoring the fetal heart rate allows early detection of any signs of fetal compromise. Choices B, C, and D are important assessments but not the priority in this situation. Monitoring fluid intake and output, uterine tone, and maternal blood pressure are also crucial but do not directly assess fetal well-being, which is the primary concern during labor induction with oxytocin.
A nurse is preparing a laboring person for an epidural. What is the most important nursing action prior to the procedure?
- A. ensure the birthing person is in a sitting position
- B. check for allergies to anesthesia
- C. ensure informed consent is obtained
- D. administer IV fluids
Correct Answer: C
Rationale: The correct answer is C: ensure informed consent is obtained. Prior to any medical procedure, including epidural administration, it is crucial to obtain informed consent from the patient. This involves explaining the procedure, risks, benefits, and alternatives to the patient, ensuring they understand and voluntarily agree to the procedure. Without informed consent, the procedure cannot proceed ethically.
Choice A (ensure the birthing person is in a sitting position) is not the most important action as the position can be adjusted during the procedure. Choice B (check for allergies to anesthesia) is important but obtaining informed consent takes precedence. Choice D (administer IV fluids) is not a priority before obtaining informed consent.
A woman missed her menstrual period 1 week ago and has come to the doctor’s office for a pregnancy test. Which placental hormone is measured in pregnancy tests?
- A. Progesterone
- B. Estrogen
- C. Human chorionic gonadotropin
- D. Human placental lactogen
Correct Answer: C
Rationale: Human chorionic gonadotropin is the basis for most pregnancy tests. It is detectable in maternal blood as soon as implantation occurs, usually 7 to 9 days after fertilization.
A 36-week gestation gravid lies flat on her back.
- A. Hypertension.
- B. Dizziness.
- C. Rales.
- D. Chloasma.
Correct Answer: B
Rationale: Lying flat on the back can compress the inferior vena cava, leading to reduced blood flow and dizziness. Chloasma, rales, and hypertension are unrelated to this position.
