WGU D115 OA AND PRE-OA EXAM
QUESTIONS N ANSWERS PASSED
Retinoic acid - correct answer ✔✔ An advanced practice registered nurse (APRN) is consulting
with a teen patient who has recently learned that she is pregnant. The APRN knows that a
certain medication taken by the patient can contribute to the development of congenital
malformations in the fetus. The APRN reviews the patient's current medication list and finds
one medication that is a concern.
Which medication is the APRN concerned about?
"Are you both the genetic donor parents?" - correct answer ✔✔ A newborn's screening for
cystic fibrosis is positive. An advanced practice registered nurse (APRN) is reviewing screening
results and taking a comprehensive genetic screening of the parents. The APRN asks the parents
questions to help determine the transmission of this disease.
Which question should the APRN ask?
Relative deficiency of factor B - correct answer ✔✔ A 30-day-old infant presents to the
emergency room with decreased oral intake, decreased urine output, and a fever of 101.8. The
infant is admitted for further evaluation with a workup to include a blood culture, a urine
culture, a spinal tap, and a chest X-ray.
Which issue of innate immunity, as it relates to neonates, is of concern?
C1 esterase inhibitor - correct answer ✔✔ A 12-year-old African American patient presents with
unilateral eye swelling and lower lip swelling. The patient's parent reports that the swelling is
spontaneous and resolves over several days. The patient does not have complaints of fever,
hives, or vomiting. Serum lab results show hyperactivation of three plasma protein systems. The
APRN suspects hereditary angioedema.
What is the cause of the genetic defect suspected in this situation?
, Gastroesophageal reflux disease causes aspiration of thin fluids. - correct answer ✔✔ The
parent of a child diagnosed with Down syndrome expresses concerns about the child's recurrent
respiratory tract infections to an advanced practice registered nurse (APRN). The infections have
occurred regularly since birth.
What should the APRN tell the parent is the underlying cause of this illness?

Ovarian - correct answer ✔✔ An advanced practice nurse (APRN) is working with a patient who
is choosing to undergo breast removal due to family history of breast cancer. The patient's
genetic testing revealed an abnormal BRCA1. The patient shares with the APRN that she is
relieved that she will not need to worry about cancer once the breast tissue is removed. The
APRN proceeds to educate the patient about additional risks.
Which other type of cancer is the patient at risk for developing?
A loss of myelin sheaths, causing a disruption of nerve conduction - correct answer ✔✔ A
patient presents to the hospital complaining of blurred vision, muscle weaknesses, impaired
gait, and fatigue lasting more than 24 hours. The patient has a history of smoking and vitamin D
deficiency. Extensive diagnostic testing and a comprehensive neurological assessment reveals a
diagnosis of multiple sclerosis.
Which pathological mechanism will support this diagnosis?
