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.

A client who is 4 months pregnant is at the prenatal clinic for her initial visit. Her history reveals she has 7-year-old twins who were born at 34 weeks gestation, a 2-year-old son born at 39 weeks gestation, and a spontaneous abortion 1 year ago at 6 weeks gestation. Using the GTPAL method, the nurse would document her obstetric history as:
- A. 3-2-1-0-3
- B. 4-1-1-1-3
- C. 4-2-1-3-1
- D. 3-1-2-2-3
Correct Answer: B
Rationale: GTPAL: Gravida (4 pregnancies: twins, son, abortion, current), Term (1 at 39 weeks), Preterm (1 at 34 weeks), Abortions (1 at 6 weeks), Living (3 children). Thus, 4-1-1-1-3 is correct. Other options miscalculate pregnancies, preterm births, or living children.
A client with hyperemesis gravidarum is admitted to the facility after being cared for at home without success. What would the nurse expect to include in the client's plan of care?
- A. clear liquid diet
- B. administration of diethylstilbestrol
- C. total parenteral nutrition
- D. nothing by mouth
Correct Answer: C
Rationale: Hyperemesis gravidarum causes severe vomiting, risking dehydration and malnutrition. Total parenteral nutrition delivers complete nutrients intravenously, addressing these risks when oral intake fails. Clear liquids or nothing by mouth worsen malnutrition, and diethylstilbestrol, a discontinued drug, is irrelevant.
A client is diagnosed with gestational hypertension and is receiving magnesium sulfate. Which finding would the nurse interpret as indicating a therapeutic level of medication?
- A. Difficulty in arousing
- B. Deep tendon reflexes 2+
- C. Urinary output of 30 mL per hour
- D. Respiratory rate of 10 breaths/minute
Correct Answer: B
Rationale: Deep tendon reflexes at 2+ indicate a therapeutic magnesium level, preventing seizures without toxicity. Difficulty arousing, low urinary output (below 40 mL/hr), or respiratory rate of 10 suggest toxicity, requiring intervention.
A client's last menstrual period was April 11. Using Nägele's rule, her estimated date of birth (EDB) would be:
- A. 18-Feb
- B. 18-Jan
- C. 8-Jan
- D. 28-Dec
Correct Answer: B
Rationale: Nägele's rule: add 1 year, subtract 3 months, add 7 days. April 11, 2023 + 1 year = April 11, 2024; minus 3 months = January 11, 2024; plus 7 days = January 18, 2024. Other options misapply the rule.
A nurse is preparing to infuse 1 liter of 0.9% sodium chloride IV over 8 hr with a tubing set that delivers 15 gtts/mL. The nurse should set the manual IV infusion to deliver how many drops/min?
- A. 31 gtts/min
- B. 30 gtts/min
- C. 32 gtts/min
- D. 29 gtts/min
Correct Answer: A
Rationale: Formula: gtts/min = (volume x drop factor) / time. (1000 mL x 15 gtts/mL) / (8 x 60 min) = 15000 / 480 = 31.25, rounded to 31 gtts/min. Other options miscalculate the rate.
