Sample RNC-MNN Practice Questions

Try these sample questions to review concepts for the RNC-MNN exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 115+ question experience with AI tutoring.

1A postpartum client is experiencing heavy lochia with large clots. Which of the following is the nurse's priority action?
A.Assess the client's blood pressure.
B.Massage the uterine fundus.
C.Administer a prescribed oxytocic medication.
D.Encourage the client to ambulate to expel the clots.
Explanation: The nurse's priority action is to massage the uterine fundus. A boggy uterus is a primary cause of postpartum hemorrhage, and fundal massage helps to stimulate uterine contractions and control bleeding.
2Which finding in a 24-hour-old newborn should be reported to the healthcare provider immediately?
A.Acrocyanosis
B.Jaundice limited to the face
C.A heart rate of 140 beats per minute
D.Nasal flaring and grunting
Explanation: Nasal flaring and grunting are signs of respiratory distress in the newborn and should be reported immediately. These findings may indicate a serious underlying condition, such as respiratory distress syndrome or transient tachypnea of the newborn.
3A nurse is teaching a new mother about breastfeeding. Which statement indicates that the mother understands the teaching?
A."I should feed my baby every 4-5 hours."
B."I should supplement with formula if my baby seems hungry after breastfeeding."
C."I should hear a clicking sound when my baby is nursing."
D."I should offer both breasts at each feeding."
Explanation: Offering both breasts at each feeding helps to ensure adequate milk supply and provides the baby with both foremilk and hindmilk. The mother should be encouraged to start feedings on the breast that was offered last at the previous feeding.
4A newborn is diagnosed with developmental dysplasia of the hip (DDH). Which of the following is a classic sign of this condition?
A.Symmetrical gluteal folds
B.Negative Ortolani test
C.Limited adduction of the affected hip
D.Asymmetrical thigh creases
Explanation: Asymmetrical thigh creases are a classic sign of DDH. Other signs include limited abduction of the affected hip and a positive Ortolani or Barlow test.
5A postpartum client who had a cesarean birth reports severe headache and blurred vision. Which condition should the nurse suspect?
A.Postpartum depression
B.Preeclampsia
C.Spinal headache
D.Normal postpartum discomfort
Explanation: Severe headache and blurred vision are classic signs of preeclampsia, a serious condition that can occur during pregnancy or in the postpartum period. The nurse should assess the client's blood pressure and notify the healthcare provider immediately.
6A nurse is assessing a newborn's reflexes. To elicit the Moro reflex, the nurse should:
A.Strike the crib mattress.
B.Place a finger in the newborn's palm.
C.Turn the newborn's head to one side.
D.Stroke the sole of the newborn's foot.
Explanation: The Moro reflex is elicited by a sudden loud noise or a change in position, such as striking the crib mattress. The newborn will respond by extending and then abducting the arms and legs.
7A client who is 2 days postpartum and breastfeeding develops a fever of 38.5°C (101.3°F) and unilateral breast tenderness. The nurse should suspect which of the following?
A.Endometritis
B.Mastitis
C.Engorgement
D.Urinary tract infection
Explanation: The combination of fever and unilateral breast tenderness in a breastfeeding client is highly suggestive of mastitis, an infection of the breast tissue. The nurse should instruct the client to continue breastfeeding and seek medical attention.
8A newborn born to a mother with diabetes is at increased risk for which of the following complications?
A.Hyperglycemia
B.Hypoglycemia
C.Hyperthermia
D.Polycythemia
Explanation: Newborns of diabetic mothers are at increased risk for hypoglycemia after birth. The fetus produces high levels of insulin in response to the mother's high blood glucose levels, and this high insulin level continues after birth, leading to a rapid drop in blood glucose.
9A nurse is providing discharge teaching to a new mother about umbilical cord care. Which instruction is appropriate?
A."Apply alcohol to the cord with each diaper change."
B."Keep the cord covered with the diaper."
C."The cord will fall off in about 2-3 weeks."
D."Clean the cord with soap and water if it becomes soiled."
Explanation: The umbilical cord stump typically dries and falls off within 10 to 14 days, but can take up to 3 weeks. Parents should be instructed to keep the cord clean and dry until it falls off.
10A postpartum client is diagnosed with a deep vein thrombosis (DVT). Which of the following is a priority nursing intervention?
A.Encourage ambulation to promote circulation.
B.Apply warm, moist compresses to the affected leg.
C.Massage the affected leg to relieve pain.
D.Maintain the client on strict bed rest.
Explanation: Current postpartum DVT care emphasizes early ambulation once anticoagulation is initiated, along with elevation of the affected leg and avoidance of leg massage. Bed rest is no longer recommended because it does not reduce embolism risk and increases venous stasis.
