NCLEX Pharmacology Quiz 35 Maternity And Newborn Medications

1. Rho(D) immune globulin (RhoGAM) is given to a pregnant woman after delivery and the nurse is giving information to the patient about the indication of the medication. The nurse determines that the patient understands the purpose of the medication if the patient tells that it will protect her baby from which of the following?

Developing German Measles.

Developing Pernicious anemia.

Developing Rh incompatibility.

Having an RH+ blood.

Rh incompatibility can develop when a Rh-negative mother becomes sensitized to the RH antigen. Sensitization may occur when a Rh-negative woman becomes pregnant with a fetus who is Rh positive. Blood cells from the baby may cross the maternal bloodstream. which can happen during pregnancy. labor. and delivery. causing the mother’s immune system to form antibodies. against Rh-positive blood. Administration of the Rhogam prevents the mother from developing antibodies against Rh-positive blood by providing passive antibody protection against the Rh antigen.Options A and B are not related to the Rh incompatibility.Option D is not indicated for the administration of Rhogam.

Oxycodone (Oxycontin).

Meperidine hydrochloride (Demerol).

Morphine sulfate.

Opioid analgesics are prescribed for to pregnant women who are experiencing moderate to severe labor pains. Respiratory depression may occur as a sign of opioid toxicity.

3. A nurse instructor is about to administer a vitamin K injection to a newborn. The student nurse asks the instructor regarding the purpose of the injection. The appropriate response would be:

“The vitamin K provides active immunity.”

“The vitamin K will prevent the occurrence of hyperbilirubinemia.”

“The vitamin K will protect the newborn from bleeding.”

“The vitamin K will serve as protection against jaundice and anemia.”

Vitamin K is administered to the newborn in order to prevent bleeding disorders. Vitamin K promotes the formation of clotting factors II. VII. IX & X in which the infants lack because of insufficient intestinal bacteria needed for synthesizing fat-soluble vitamin K.Option A: Vitamin K does not promote the development of immunity.Option B: Vitamin K does not prevent the occurrence of hyperbilirubinemia.Option D: Vitamin K doesn’t prevent the newborn from having jaundice or anemia.

Acute Gastroenteritis.

Hypothyroidism.

Methylergonovine (Methergine) is a medication used to treat postpartum bleeding. However, it is contraindicated in patients with ischemic heart disease, as it can cause vasoconstriction and potentially worsen the condition. Therefore, it is important for the nurse to contact the physician if ischemic heart disease is documented in the patient's chart before administering the medication.

Sufentanil (Sufenta).

Betamethasone (Celestone).

Butorphanol tartrate (Stadol).

Glucocorticoids such as betamethasone and dexamethasone are being used to increase the production of surfactant to aid in fetal lung maturation.

Early decelerations of the fetal heart rate.

Fatigue.

Nausea.

Uterine hyperstimulation.

Oxytocin is used to induce labor by stimulating uterine contraction.

Urine output.

Blood pressure.

Vaginal bleeding.

“I will flush the newborn‘s eyes after instilling the ointment.”

“I will clean the newborn‘s eyes before instilling the ointment.”

“I need to administer the eye ointment within an hour after maternal delivery.”

Flushing the newborn's eyes after instilling erythromycin ointment is not recommended as it can remove the medication before it has a chance to work effectively. The correct procedure involves cleaning the eyes before administration, instilling the ointment into the conjunctival sacs, and allowing the medication to remain in the eyes to prevent infection.
