What drug is an anxiolytic that relieves apprehension and creates a feeling of calm?
- A. hydroxyzine
- B. fentanyl
- C. codeine
- D. morphine
Correct Answer: A
Rationale: The correct answer is A: hydroxyzine. Hydroxyzine is an anxiolytic medication that acts on the central nervous system to relieve apprehension and induce a calming effect. It is commonly used to treat anxiety and tension. Fentanyl, codeine, and morphine are opioid medications primarily used for pain relief and do not have anxiolytic properties. Therefore, hydroxyzine is the correct choice for a drug that specifically targets anxiety and promotes a feeling of calm.

The laboring person wants to use open glottis breathing for pushing. How can the nurse support the person?
- A. Encourage the person to breathe however is most comfortable.
- B. Tell the person they should hold their breath for 10 counts.
- C. Explain that open glottis pushing is not effective.
- D. Discuss that the health-care provider would not allow them to use that breathing.
Correct Answer: A
Rationale: The correct answer is A because open glottis breathing is a common technique during the pushing stage of labor as it helps prevent breath-holding and excessive pressure buildup. By encouraging the person to breathe however is most comfortable, the nurse supports their autonomy and allows them to effectively engage in open glottis breathing.
Choice B is incorrect because holding the breath for counts can lead to increased intra-abdominal pressure and is not recommended during pushing. Choice C is incorrect as open glottis breathing is an effective technique for pushing. Choice D is incorrect as healthcare providers typically support the individual's chosen breathing techniques during labor.
The nurse is reviewing the cardinal maneuvers of labor and birth with a group of nursing students. Which maneuver will immediately follow the birth of the baby's head?
- A. Expulsion
- B. Restitution
- C. Internal rotation
- D. External rotation
Correct Answer: A
Rationale: After the baby's head is born, the immediate next step is the expulsion of the baby's body. This is because the expulsion maneuver refers to the delivery of the rest of the baby's body following the birth of the head. Restitution, internal rotation, and external rotation occur before the birth of the baby's head and are part of the cardinal movements of labor and birth. Restitution involves the realignment of the baby's head with their body after the head is born. Internal rotation refers to the baby's head turning to navigate through the birth canal. External rotation involves the baby's head turning back to its original position after delivery. So, the correct answer is A (Expulsion), as it directly follows the birth of the baby's head.
Which aspect of newborn assessment may be limited by the application of a vacuum extractor at birth?
- A. Anterior fontanel
- B. Coronal suture lines
- C. Posterior fontanel
- D. Biparietal diameter
Correct Answer: C
Rationale: The correct answer is C: Posterior fontanel. When a vacuum extractor is used during birth, it can cause swelling or molding of the baby's head, which may affect the assessment of the posterior fontanel. This fontanel is an important landmark for determining head size and shape. Swelling or molding can make it difficult to accurately assess the fontanel's size and shape, potentially impacting the overall assessment of the newborn's head.
A: The anterior fontanel is not typically affected by the use of a vacuum extractor.
B: The coronal suture lines are not directly impacted by the vacuum extractor.
D: The biparietal diameter can still be measured accurately even with molding caused by the vacuum extractor.
While assisting with a vacuum extraction birth, which alteration should the nurse immediately report to the obstetric provider?
- A. Maternal pulse rate of 100 bpm
- B. Maternal blood pressure of 120/70 mm Hg
- C. Persistent fetal bradycardia below 100 bpm
- D. Decreased intensity of uterine contractions
Correct Answer: C
Rationale: The correct answer is C: Persistent fetal bradycardia below 100 bpm. This is crucial because it indicates fetal distress and requires immediate intervention to prevent potential harm to the baby. Bradycardia below 100 bpm may indicate inadequate oxygen supply to the fetus, necessitating urgent action. Maternal vital signs in choices A and B are within normal ranges. Choice D, decreased intensity of uterine contractions, while important, is not as critical as fetal bradycardia in this scenario.
Which physiologic effect may occur in the presence of increased maternal pain perception during labor?
- A. Increase in uterine contractions in response to catecholamine secretion
- B. Decrease in blood pressure in response to alpha receptors
- C. Decreased perfusion to the placenta in response to catecholamine secretion
- D. Increased uterine blood flow, causing increase in maternal blood pressure
Correct Answer: C
Rationale: The correct answer is C. Increased maternal pain perception during labor can lead to decreased perfusion to the placenta due to catecholamine secretion. When a mother experiences pain, stress hormones like catecholamines are released, causing vasoconstriction of blood vessels, including those supplying the placenta. This vasoconstriction reduces blood flow to the placenta, potentially compromising fetal oxygenation and nutrient delivery.
Choice A is incorrect because increased catecholamine secretion would not directly cause an increase in uterine contractions. Choice B is incorrect because alpha receptors are not typically involved in decreasing blood pressure in response to pain perception. Choice D is incorrect because increased uterine blood flow would not cause an increase in maternal blood pressure; in fact, it would likely have the opposite effect as increased blood flow typically leads to decreased blood pressure.
