VATI Maternal Newborn Assessment Questions
Question 1 of 5
What is the primary reason for administering Rh immunoglobulin to an Rh-negative mother after delivery?
Correct Answer: A
Rationale: Rh immunoglobulin prevents maternal sensitization to Rh-positive blood.
Question 2 of 5
During a trauma-informed gynecologic examination, what principle emphasizes the importance of involving the patient in decision making about their health care?
Correct Answer: A
Rationale:
Question 3 of 5
A nurse is caring for a client who is in labor and has an external fetal monitor. The nurse observes late decelerations on the monitor strip and interprets them as indicating which of the following?
Correct Answer: A
Rationale: Late decelerations on the fetal monitor strip indicate uteroplacental insufficiency. These decelerations occur after the peak of a contraction, and the fetus may not receive enough oxygen-rich blood during contractions. Uteroplacental insufficiency can lead to fetal hypoxia and acidosis if not addressed promptly. It is important for the nurse to take appropriate steps to improve fetal oxygenation, such as repositioning the mother, administering oxygen, and adjusting IV fluids. If late decelerations persist, further interventions may be necessary to ensure the well-being of the fetus.
Question 4 of 5
A nurse is preparing to administer methylergonovine 0.2 mg orally to a client who is 2 hr. postpartum and has a boggy uterus. For which of the following assessment findings should the nurse withhold the medication?
Correct Answer: A
Rationale: Methylergonovine is a medication used to help contract the uterus and control postpartum hemorrhage. One of its side effects is vasoconstriction, which can lead to increased blood pressure. The client's blood pressure of 142/92 mm Hg is elevated, and administering methylergonovine could further increase the blood pressure, potentially causing harm to the client. It is important to withhold the medication in this situation to prevent worsening of hypertension. The other assessment findings are within normal ranges and do not contraindicate the administration of methylergonovine.
Question 5 of 5
The nurse is explaining how a newly delivered baby initiates respiration. Which statement explains this process?
Correct Answer: A
Rationale: The correct statement explaining how a newly delivered baby initiates respiration is "Chemical thermal and mechanical factors." When a baby is born, various factors come into play to stimulate the baby's first breath. Chemically, the baby senses a decrease in oxygen and an increase in carbon dioxide levels, triggering the respiratory centers in the brain to start the breathing process. Thermally, exposure to the cooler air outside the womb stimulates the baby's skin receptors, encouraging the baby to take a breath. Mechanically, the pressure changes during delivery and the physical stimulation of the baby's face and body also play a role in initiating respiration. Overall, it is the combined effect of these chemical, thermal, and mechanical factors that help a newly delivered baby begin breathing independently.
