NUR 221 EXAM 2 | VERIFIED ACTUAL QUESTIONS AND CORRECT
ANSWERS WITH RATIONALES | NEW UPDATE 2025
Master your NUR 221 Exam 2 with this comprehensive question set that reflects the
current 2025-2026 exam outline. This collection covers all essential topics, including
fetal heart rate interpretation, labor stages, preeclampsia management, obstetric
emergencies, and pharmacologic interventions.
What is the normal range for AST?
CORRECT ANSWER ✓ ✓ 10 - 30 u/L
Rationale: This indicates normal liver enzyme levels, with elevations suggesting liver
damage.
What is the normal range for ALT?
CORRECT ANSWER ✓ ✓ 10 - 40 u/L
Rationale: This is the expected range for this liver-specific enzyme, which rises with liver
cell injury.
What is the normal range for Creatinine?
CORRECT ANSWER ✓ ✓ 0.6 - 1.2 mg/dL
Rationale: This range reflects normal kidney function in filtering waste from the blood.
What is the normal range of hematocrit for women?
CORRECT ANSWER ✓ ✓ 37 - 47%
Rationale: This is the normal percentage of red blood cells in the blood for an adult
female.
,What is the normal range for hemoglobin?
CORRECT ANSWER ✓ ✓ 12 - 18 g/dL
Rationale: This range signifies adequate oxygen-carrying capacity in the blood.
What is the normal range for platelets?
CORRECT ANSWER ✓ ✓ 150,000 - 400,000 cells/mcL
Rationale: This count is necessary for proper blood clotting function.
What is the normal FHR (fetal heart rate) range?
CORRECT ANSWER ✓ ✓ 110 to 160 beats/min
Rationale: This baseline range reflects adequate oxygenation and normal fetal cardiac
function.
How is fetal tachycardia defined?
CORRECT ANSWER ✓ ✓ As a baseline FHR greater than 160 beats/min for 10 minutes
or longer.
Rationale: It is a sign of fetal stress, often from infection, hypoxia, or maternal fever.
How is fetal bradycardia defined?
CORRECT ANSWER ✓ ✓ As a baseline FHR less than 110 beats/min for 10 minutes or
longer.
Rationale: This indicates fetal distress, often from hypoxia, umbilical cord compression, or
anesthetics.
What three important questions does Leopold Maneuvers help to answer?
CORRECT ANSWER ✓ ✓ 1.) Which fetal part is in the uterine fundus? 2.) Where is the
fetal back located? 3.) What is the presenting fetal part?
Rationale: These maneuvers help determine fetal position, presentation, and engagement
in the pelvis.
, How is category I defined in the fetal heart rate classification system?
CORRECT ANSWER ✓ ✓ 1.) Baseline rate 110 to 160 beats/min 2.) Baseline FHR
variability: Moderate 3.) Late or variable decelerations: Absent 4.) Early decelerations:
Either present or absent 5.) Accelerations: Either present or absent
Rationale: This category is normal, strongly predicting a well-oxygenated, non-acidemic
fetus.
How is category II defined in the fetal heart rate classification system?
CORRECT ANSWER ✓ ✓ Includes all FHR patterns not categorized as Category I or III,
such as bradycardia with variability, minimal/marked variability, absence of
accelerations, or recurrent variable/late decelerations.
Rationale: This category is indeterminate, requiring continued surveillance and evaluation.
How is category III defined in the fetal heart rate classification system?
CORRECT ANSWER ✓ ✓ 1.) Absent baseline variability with recurrent late decelerations,
recurrent variable decelerations, or bradycardia 2.) Sinusoidal pattern
Rationale: This category is abnormal and predictive of abnormal fetal acid-base status,
requiring immediate intervention.
How can Variability of the FHR be described?
CORRECT ANSWER ✓ ✓ As irregular waves or fluctuations in the baseline FHR,
quantified in beats per minute from the peak to the trough of a cycle.
Rationale: Variability reflects a healthy nervous system and adequate fetal oxygenation.
What kind of Variability is considered normal?
CORRECT ANSWER ✓ ✓ Moderate
Rationale: Moderate variability reliably predicts the absence of fetal metabolic acidemia.
