ALREADY GRADED A+ (MOST RECENT!!)
1. A nurse is calculating a client's estimated date of delivery using
Naegele's rule. The client's last menstrual period began on November
27. Which date is the client's expected date of delivery?
A. September 3
B. September 20
C. August 3
D. August 20
Answer: A. September 3
Rationale: Naegele's rule subtracts 3 months from the first day of the LMP
and adds 7 days. November 27 minus 3 months = August 27; plus 7 days =
September 3.
2. A nurse is teaching a client who is 10 weeks gestation about
nutrition during pregnancy. Which statement by the client indicates an
understanding?
A. "I should increase my protein intake to 60 grams per day"
B. "I should drink 2 liters of water each day"
C. "I should increase my overall caloric intake by 300 calories per day"
D. "I should take 600 mcg of folic acid each day"
Answer: D. "I should take 600 mcg of folic acid each day"
Rationale: The recommended daily folic acid intake during pregnancy is 600
mcg to prevent neural tube defects.
,3. A nurse is planning care for a newborn who has neonatal abstinence
syndrome. Which of the following interventions should the nurse
include in the plan of care?
A. Swaddle the newborn in a flexed position
B. Weigh the newborn every other day
C. Increase the newborn's visual stimulation
D. Discourage parental interaction until after a social service evaluation
Answer: A. Swaddle the newborn in a flexed position
Rationale: Swaddling provides containment and reduces environmental
stimuli, which helps soothe the infant and decrease the effects of
withdrawal.
4. A client and her partner ask the nurse for information about
permanent contraception. Which of the following statements should
the nurse include in the counseling?
A. Most sterilization procedures are considered irreversible
B. A woman should use contraception for 1-2 months after a tubal ligation
C. A man is usually sterile immediately after a vasectomy
D. The menstrual cycle is shorter after a tubal ligation
Answer: A. Most sterilization procedures are considered irreversible
Rationale: Sterilization, such as tubal ligation and vasectomy, is intended to
be a permanent method of contraception.
5. A nurse is performing a routine assessment on a client who is 18
weeks gestation. Which of the following findings should the nurse
expect?
A. Deep tendon reflexes 4+
B. Fundal height 14 cm
C. Urine protein 2+
D. FHR 152/min
Answer: D. FHR 152/min
Rationale: Normal fetal heart rate ranges from 110-160 bpm. Deep tendon
reflexes should be 2+ (normal). Urine protein should be negative or trace.
,6. A nurse is teaching a client about exercise safety during pregnancy.
Which of the following statements by the client indicates an
understanding of the teaching?
A. "I will limit my time in the hot tub to 30 minutes after exercise."
B. "I should consume three 8-ounce glasses of water before I exercise."
C. "I will check my heart rate every 15 minutes while I exercise."
D. "I should avoid exercising while lying on my back after the first
trimester."
Answer: D. "I should avoid exercising while lying on my back after the
first trimester."
Rationale: After the first trimester, the supine position can cause vena cava
compression, reducing cardiac output and potentially leading to
hypotension.
7. A nurse is caring for a client who is 2 weeks postpartum following a
cesarean birth. Which of the following clinical findings should the
nurse identify as an indication of postpartum infection?
A. Unilateral breast pain
B. Stretch marks
C. Lochia alba
D. WBC 12,000/mm³
Answer: A. Unilateral breast pain
Rationale: Unilateral breast pain, redness, and warmth are characteristic of
mastitis, a postpartum infection.
8. A nurse reviews lab results for a client at 24 weeks gestation. Which
finding requires immediate intervention?
A. Hematocrit 33%
B. Leukocytes 12,000/mm³
C. Platelets 90,000/mm³
D. Fasting glucose 95 mg/dL
Answer: C. Platelets 90,000/mm³
Rationale: Platelets <100,000 may indicate immune thrombocytopenia,
HELLP syndrome, or other pathology. Gestational thrombocytopenia usually
remains >100,000.
, 9. A nurse is providing teaching to an antepartum client who reports
constipation. Which of the following food selections has the highest

A. Lentils
B. Oatmeal
C. Cabbage
D. Asparagus

initiation of the oxytocin infusion and should be reported to the
provider?
A. Baseline fetal heart rate of 110/min
B. Contractions every 8 minutes, lasting 50 seconds
C. Prolonged deceleration pattern on fetal monitoring
D. Cervical dilation of 6 cm and 100% effaced
Answer: C. Prolonged deceleration pattern on fetal monitoring
Rationale: A prolonged deceleration pattern indicates uteroplacental
insufficiency and fetal compromise, which is a contraindication for oxytocin
administration.
11. A nurse is caring for a client who has hyperemesis gravidarum and
is receiving IV fluid replacement. Which finding should the nurse
report to the provider?
A. BUN 25 mg/dL
B. Serum creatinine 0.8 mg/dL
C. Urine output 280 mL within 8 hours
D. Urine negative for ketones
Answer: A. BUN 25 mg/dL
Rationale: An elevated BUN indicates dehydration and prerenal azotemia,
which requires immediate intervention. Normal BUN is 10–20 mg/dL.
