Maternal Newborn Nursing Questions
Question 1 of 5
How does estrogen work in COC pills?
Correct Answer: A
Rationale: Estrogen in combined oral contraceptive (COC) pills works primarily by inhibiting ovulation through the suppression of the luteinizing hormone (LH) surge. By maintaining consistent levels of estrogen in the body, COC pills prevent the release of eggs from the ovary. This prevents fertilization from occurring, which is one of the main mechanisms of action of COC pills to provide contraception. While estrogen also has other effects such as stabilizing the endometrium to reduce unscheduled bleeding, its main role in COC pills is to inhibit ovulation and prevent pregnancy through hormonal regulation.
Question 2 of 5
After delivery it is determined there is a placental accreta, what intervention should the nurse anticipate?
Correct Answer: A
Rationale: In the case of placental accreta, where the placenta is abnormally attached to the uterine wall, it can be very difficult to detach the placenta without significant bleeding. In severe cases, the safest intervention to prevent life-threatening hemorrhage is a hysterectomy, which involves the removal of the uterus. This is a serious surgical procedure that may be necessary to save the mother's life. Other interventions mentioned in the options (IV antibiotic, IV Pitocin, 2L oxygen by mask) may be part of the management plan but would not address the underlying issue of placental accreta like a hysterectomy would.
Question 3 of 5
A newborn's birth was prolonged because the shoulders were very wide. The nurse performing the assessment would be particularly observant for a problem with the:
Correct Answer: A
Rationale: The Moro reflex is a normal infantile reflex that is typically present at birth and disappears around 4-6 months of age. This reflex is triggered by a sudden loss of support or a loud noise, causing the infant to throw back the head and extend the arms in a gesture as if trying to grab something. In a situation where the newborn's birth was prolonged due to wide shoulders, there is a higher risk of injury to the brachial plexus (nerves that control arm movement) during delivery. Damage to the brachial plexus can result in weakness or paralysis of the affected arm, and this may impact the Moro reflex as it involves the arms' movement. Therefore, the nurse would be particularly observant for any abnormality or lack of response in the Moro reflex as it may indicate potential nerve injury related to the difficult birth.
