A woman who is 6 weeks pregnant tells the nurse that she is worried that, even though she is taking folic acid supplements, the baby might have spina bifida because of a family history. The nurse's response should be based on what?
a. Prenatal detection is not possible yet.
b. There is no genetic basis for the defect.
c. Chromosome studies done on amniotic fluid can diagnose the defect prenatally.
d. Open neural tube defects (NTDs) result in elevated concentrations of ?-fetoprotein in amniotic fluid.
ANS: D
Ultrasound scanning and measurement of ?-fetoprotein may indicate the presence of anencephaly or myelomeningocele. The optimum time for performing this analyzing is between 16 and 18 weeks. Prenatal diagnosis is possible through amniocentesis. A multifactorial origin is suspected, including drugs, radiation, maternal malnutrition, chemicals, and possibly a genetic mutation. Chromosome abnormalities are not present in NTDs.

A patient with a massive upper gastrointestinal hemorrhage is exhibiting signs and symptoms of hypovolemic shock. What most specific treatment does the nurse anticipate?
A) Admission to a general care nursing unit for monitoring B) Initial fluid resuscitation with intravenous crystalloids C) Diet of clear liquids, advanced as tolerated D) Bed rest in semi-Fowler's position
A 2-year-old girl fell approximately 12 feet from a second-story window, landing on her head. Your primary assessment reveals that she is unresponsive; has slow, irregular respirations; and has blood draining from her mouth and nose. A rapid scan of her body does not reveal any gross injuries or bleeding. You should:
A) manually stabilize her head and neck in a neutral position, insert a nasal airway, and hyperventilate her at a rate of 35 breaths/min. B) suction her mouth and nose for no longer than 15 seconds, insert an oral airway, and apply high-flow oxygen with a pediatric nonrebreathing mask. C) open her airway with the jaw-thrust maneuver, suction her mouth and nose, insert an oral airway, and assist her ventilations with a bag-mask device. D) insert an oral airway, apply a cervical collar, preoxygenate her with a bag-mask device and 100% oxygen for 30 seconds, and intubate her trachea.
She asks you which method you would pick. What do you tell her?
