A client comes to the prenatal clinic for her first visit. When determining the client's estimated due date, the nurse understands which method is the most accurate.
- A. Nagele's rule
- B. Ultrasound
- C. Gestation wheel
- D. Birth calculator
Correct Answer: B
Rationale: Ultrasound in the first trimester measures fetal size accurately for due date estimation, unlike Nagele's rule, gestation wheel, or calculators, which rely on less precise menstrual data or assumptions.

After reviewing the information provided in the client's medical record, which of the following complications should the nurse identify that the client is at risk of developing?
- A. Preeclampsia; uric acid
- B. Gestational diabetes; glucose
- C. Eclampsia; magnesium
- D. Placenta previa; hemoglobin
Correct Answer: B
Rationale: Gestational diabetes risk is linked to glucose intolerance, detectable by serum glucose levels, causing complications like macrosomia. Preeclampsia involves hypertension, not uric acid alone; eclampsia isn't tied to magnesium levels; placenta previa relates to prior surgeries, not hemoglobin.
A nurse is preparing to administer chlordiazepoxide 50 mg PO every 8 hours to a client. The amount available is chlordiazepoxide 25 mg per capsule. How many capsules should the nurse administer per dose?
- A. 2 capsules
- B. 1 capsule
- C. 3 capsules
- D. 4 capsules
Correct Answer: A
Rationale: Dose (50 mg) / concentration (25 mg/capsule) = 2 capsules per dose. Other options miscalculate the number needed to achieve 50 mg.
A nurse is conducting an in-service program for a group of nurses working at the women's health facility about the causes of spontaneous abortion. The nurse determines that the teaching was successful when the group identifies which condition as the most common cause of first trimester abortions?
- A. Cervical insufficiency
- B. Uterine fibroids
- C. Fetal genetic abnormalities
- D. Maternal disease
Correct Answer: C
Rationale: Fetal genetic abnormalities, like chromosomal errors, cause ~70% of first trimester abortions. Cervical insufficiency affects later trimesters, fibroids and maternal diseases (e.g., diabetes) are less common causes early on.
A nurse is planning a presentation about HIV for a church-based group. Which of the following information about HIV transmission should the nurse include?
- A. It is primarily transmitted through mosquitoes.
- B. It is primarily transmitted through accidental puncture wounds.
- C. It is primarily transmitted through casual contact.
- D. It is primarily transmitted through direct contact with infected body fluids.
Correct Answer: D
Rationale: HIV spreads mainly through direct contact with infected fluids (blood, semen, vaginal fluid), like during sex or needle sharing. Mosquitoes, casual contact, and puncture wounds (rare) aren't primary modes.
A pregnant woman undergoes a triple/quadruple screen at 16 to 18 weeks' gestation. What would the nurse suspect if the woman's alpha-fetoprotein (AFP) level is decreased?
- A. Sickle-cell anemia
- B. Cardiac defects
- C. Down syndrome
- D. Respiratory disorders
Correct Answer: C
Rationale: Decreased AFP, with altered hCG and estriol, suggests Down syndrome (trisomy 21). Sickle-cell anemia, cardiac defects, and respiratory disorders don't typically lower AFP; cardiac defects may raise it.
