a.	augment labor.”
b.	control postpartum bleeding.”
c.	induce abortion.”

2. The nurse has just administered intravenous (IV) methylergonovine (Methergine) to a postpartum patient to prevent bleeding. Later in the shift, the patient begins to vomit and complains of nausea and a headache. The nurse initially should assess the patient’s

a.	bleeding status.
b.	blood pressure.
c.	headache.
d.	renal function.

 

 

ANS:   B

The nurse should assess the patient’s blood pressure first. Hypertension can be severe and may be associated with nausea, vomiting, headache, and convulsions. Death also is possible.

Nothing indicates that the patient’s bleeding status needs to be checked; the symptoms described are associated with hypervolemia.

Migraine may occur with methylergonovine, but the initial assessment should be the blood pressure.

Nothing indicates that the kidneys are being affected.

3. An obstetric nurse is caring for a patient in preterm labor. The nurse implements an order for IV magnesium sulfate. Which clinical manifestations would indicate that the patient has received too much of the medication?

a.	Temperature of 104.4° F
b.	Paralytic ileus
c.	Hypertension
d.	Confusion

Toxic amounts of magnesium sulfate can cause paralytic ileus and hypothermia. Initial maternal reactions include transient hypotension, flushing, headache, dizziness, lethargy, dry mouth, and a feeling of warmth.

Hyperthermia, hypertension, and confusion are not adverse effects of magnesium sulfate

4. The nurse is monitoring a patient who is having her sixth child. The patient has gone beyond term, and labor is being induced with oxytocin (Pitocin). The nurse understands that this patient is at risk for

a.	hemorrhage.
b.	placental insufficiency.
c.	uterine rupture.
d.	water intoxication.

 

 

ANS:   C

Induction of labor in women of high parity (five or more pregnancies) carries a high risk of uterine rupture, and oxytocin should be used with great caution.

Oxytocin poses no apparent risk of hemorrhage or placental insufficiency.

The patient would be at risk for water intoxication if high doses of oxytocin were being administered.
