the ATI PN Proctored Maternal Newborn exam, covering antepartum, intrapartum,
postpartum, and newborn assessment topics with detailed EXPERT RATIONALE for
every answer.
• Use these questions to strengthen clinical reasoning, identify knowledge gaps, and
build confidence through repeated practice with exam-style content and evidence-
based EXPERT RATIONALE that explain the "why" behind each correct answer.
QUESTION 1
A primigravida client at 20 weeks gestation reports experiencing dark vaginal
bleeding with severe lower abdominal cramping. Which assessment finding
would most likely indicate a threatened abortion?
A) Closed cervical os with heavy vaginal bleeding
B) Open cervical os with passage of products of conception
C) Closed cervical os with vaginal spotting
D) Dilated cervix with fetal cardiac activity present
E) Fully effaced cervix with bloody show
CORRECT ANSWER: C) Closed cervical os with vaginal spotting
EXPERT RATIONALE: In a threatened abortion, the cervical os remains closed and
there is vaginal bleeding. This is the earliest stage of abortion, where the pregnancy
may continue if the bleeding stops. Option A includes heavy bleeding which
suggests incomplete or inevitable abortion. Option B indicates incomplete abortion
,(os is open). Option D describes a viable pregnancy with cervical changes. Option E
represents normal labor progression with bloody show, not an abortion. The key
differentiating feature of threatened abortion is the closed cervical os combined
with vaginal spotting, indicating the pregnancy may still be salvageable.
QUESTION 2
A client in the second trimester is diagnosed with gestational diabetes
mellitus (GDM). Which dietary intervention should the PN prioritize in the
teaching plan?
A) Eliminate all carbohydrates from the diet
B) Distribute carbohydrates evenly throughout the day in appropriate portions
C) Increase protein intake to 200 grams daily
D) Consume simple sugars only before bedtime
E) Restrict fluid intake to prevent hyperglycemia
CORRECT ANSWER: B) Distribute carbohydrates evenly throughout the day
in appropriate portions
EXPERT RATIONALE: Even distribution of carbohydrates throughout the day helps
maintain stable blood glucose levels in GDM. This prevents both hypoglycemia and
hyperglycemia. Option A is incorrect because carbohydrates are necessary for fetal
development and maternal energy. Option C sets an unrealistic and excessive
protein goal. Option D would worsen glycemic control at night. Option E has no
bearing on blood glucose management. The ADA and ACOG recommend a
balanced diet with consistent carbohydrate distribution across meals and snacks
for optimal glucose control in gestational diabetes.
QUESTION 3
,A client who is 36 weeks pregnant presents with a blood pressure of 165/110
mmHg, reports a headache, and has 3+ proteinuria. Which complication
should the PN suspect?
A) Chronic hypertension
B) Preeclampsia with severe features
C) Gestational hypertension
D) Essential hypertension
E) Transient hypertension of pregnancy
CORRECT ANSWER: B) Preeclampsia with severe features
EXPERT RATIONALE: Severe features of preeclampsia include systolic BP ≥160
mmHg or diastolic BP ≥110 mmHg, significant proteinuria (≥3+), and symptoms
such as headache or visual disturbances. This client meets all criteria for severe
preeclampsia and requires immediate intervention. Option A (chronic
hypertension) develops before pregnancy. Option C (gestational hypertension) has
elevated BP without proteinuria. Option D (essential hypertension) is pre-existing.
Option E is not a formal diagnosis. The combination of severe hypertension,
proteinuria, and neurological symptoms is pathognomonic for severe
preeclampsia.
QUESTION 4
During the active phase of labor, a multigravida client is 6 cm dilated and
reports intense contractions. The fetal heart rate shows a variable
deceleration pattern. Which nursing action is MOST appropriate?
A) Notify the provider immediately and prepare for cesarean delivery
B) Reposition the client and perform amnioinfusion
C) Change the client's position and assess the fetal heart rate response
D) Administer oxygen and increase intravenous fluids
E) Request an epidural to reduce maternal anxiety
, CORRECT ANSWER: C) Change the client's position and assess the fetal
heart rate response
EXPERT RATIONALE: Variable decelerations are often caused by umbilical cord
compression and can frequently be relieved by changing maternal position. This
simple intervention should be tried first before escalating care. Option A is
premature without further assessment. Option B (amnioinfusion) may be
considered if variable decelerations persist despite position changes. Option D is
supportive but does not address the underlying cause of the deceleration pattern.
Option E does not address the fetal heart rate issue. Position changes (left lateral,
right lateral, or hands-and-knees) are the first-line intervention for variable
decelerations in labor.
QUESTION 5
A client delivered a 3,800-gram male infant vaginally 2 hours ago. She is now
experiencing moderate vaginal bleeding with passage of clots. Her uterus is
soft and boggy. Which medication should the PN anticipate administering?
A) Magnesium sulfate
B) Oxytocin (Pitocin)
C) Misoprostol (Cytotec)
D) Methylergonovine (Methergine)
E) Prostaglandin F2 alpha
CORRECT ANSWER: B) Oxytocin (Pitocin)
EXPERT RATIONALE: A soft, boggy uterus with moderate bleeding indicates uterine
atony, the most common cause of postpartum hemorrhage. Oxytocin is the first-
line medication for this condition as it causes uterine contraction and compression
of bleeding vessels. Option A (magnesium sulfate) is used for seizure prophylaxis in
preeclampsia. Option C (misoprostol) can be used but is not first-line. Option D
(methylergonovine) is contraindicated if hypertension is present and causes
sustained contraction. Option E is reserved for severe hemorrhage refractory to
