1. The healthcare provider prescribes magnesium sulfate 6 grams intravenously (IV) to be infused over 20 minutes for a client with preterm labor. The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse set the infusion pump?

• A. 150 mL/hour
• B. 250 mL/hour
• C. 50 mL/hour
• D. 275 mL/hour

Correct answer: A

Rationale: To calculate the infusion rate, first, determine the total volume to be infused (6 grams of magnesium sulfate) over a specific time frame (20 minutes). Then, calculate the concentration of magnesium sulfate in the IV bag to determine the mL/hour rate. The IV bag contains 20 grams of magnesium sulfate in 500 mL of solution, which means there are 4 grams of magnesium sulfate per 100 mL. Since 6 grams are required, the nurse should set the pump to deliver 150 mL/hour to infuse the prescribed dose over 20 minutes. Choice B, 250 mL/hour, is incorrect because it miscalculates the amount of magnesium sulfate infused per hour. Choice C, 50 mL/hour, is incorrect as it is too slow to deliver the required dose in the specified time frame. Choice D, 275 mL/hour, is incorrect as it overestimates the infusion rate and would deliver the dose too quickly.

2. An infant with tetralogy of Fallot becomes acutely cyanotic and hyperneic. Which action should the nurse implement first?

• A. Place the infant in a knee-chest position.
• B. Administer morphine sulfate.
• C. Start intravenous fluids.
• D. Provide 100% oxygen by face mask.

Correct answer: A

Rationale: In a tetralogy of Fallot situation, placing the infant in a knee-chest position is the initial priority to help increase systemic vascular resistance, which reduces the right-to-left shunt and improves oxygenation. This position can assist in optimizing oxygen levels before considering other interventions. Administering morphine sulfate (choice B) is not the first-line treatment for tetralogy of Fallot crisis. Starting intravenous fluids (choice C) may be necessary but is not the priority in this situation. Providing 100% oxygen by face mask (choice D) may not fully address the underlying issue of decreased systemic vascular resistance that leads to cyanosis in tetralogy of Fallot.

3. A client receiving oxytocin (Pitocin) to augment early labor. Which assessment is most important for the nurse to obtain each time the infusion rate is increased?

• A. Pain level
• B. Blood pressure
• C. Infusion site
• D. Contraction pattern

Correct answer: D

Rationale: When a client is receiving oxytocin to augment labor, the most crucial assessment for the nurse to obtain each time the infusion rate is increased is monitoring the contraction pattern. Increasing the infusion rate of oxytocin can lead to stronger and more frequent contractions, which can have implications for both the mother and the baby. Monitoring the contraction pattern helps ensure the safe administration of oxytocin and allows for timely interventions if needed.

4. During a newborn assessment, which symptom would indicate respiratory distress if present in a newborn?

• A. Flaring of the nares.
• B. Shallow and irregular respirations.
• C. Respiratory rate of 50 breaths per minute.
• D. Abdominal breathing with synchronous chest movement.

Correct answer: A

Rationale: Flaring of the nares is a classic sign of respiratory distress in newborns. It indicates that the newborn is working hard to breathe, and immediate attention should be given to assess and address the respiratory status of the infant.

5. When assessing a client who is at 12-weeks gestation, the LPN/LVN recommends that she and her husband consider attending childbirth preparation classes. When is the best time for the couple to attend these classes?

• A. At 16 weeks gestation.
• B. At 20 weeks gestation.
• C. At 24 weeks gestation.
• D. At 30 weeks gestation.

Correct answer: D

Rationale: The best time for the couple to attend childbirth preparation classes is around 30 weeks gestation, which is during the third trimester. Attending classes at this time allows the couple to learn essential information and skills as labor and delivery are approaching, maximizing the benefit of the classes. Option A is too early in the second trimester, and the couple might forget important details by the time labor approaches. Option B is also early in the second trimester, and attending later allows for better preparation. Option C is still in the second trimester, and waiting until the third trimester provides more practical knowledge closer to delivery.
