HESI Maternity Test Bank Questions
Question 1 of 5
The caregiver observes a mother giving her 11-month-old ferrous sulfate (iron drops), followed by 2 ounces of orange juice. What should the caregiver do next?
Correct Answer: D
Rationale: The high vitamin C content in orange juice aids in the absorption of iron. Providing positive feedback to the mother for administering the iron drops with orange juice is appropriate as it enhances iron absorption, benefiting the infant. Encouraging and acknowledging correct medication administration can help reinforce good practices and build confidence in the caregiver.
Question 2 of 5
The healthcare provider is assessing a 2-hour-old infant born by cesarean delivery at 39-weeks gestation. Which assessment finding should receive the highest priority when planning the infant's care?
Correct Answer: C
Rationale: A high respiratory rate in a newborn is concerning as it may indicate respiratory distress, which requires immediate attention to ensure adequate oxygenation. Monitoring and addressing respiratory issues take precedence over other parameters in the initial assessment of a newborn.
Question 3 of 5
The healthcare provider is preparing to administer magnesium sulfate to a laboring client whose blood pressure has increased from 110/60 mmHg to 140/90 mmHg. Which action is the highest priority?
Correct Answer: B
Rationale: Having calcium gluconate readily available is crucial when administering magnesium sulfate, as it serves as the antidote in case of magnesium toxicity. Magnesium sulfate can lead to respiratory depression and cardiac arrest in cases of overdose or toxicity, making the prompt availability of calcium gluconate essential for immediate administration to counteract these effects.
Question 4 of 5
The caregiver observes a mother giving her 11-month-old ferrous sulfate (iron drops), followed by 2 ounces of orange juice. What should the caregiver do next?
Correct Answer: D
Rationale: The high vitamin C content in orange juice aids in the absorption of iron. Providing positive feedback to the mother for administering the iron drops with orange juice is appropriate as it enhances iron absorption, benefiting the infant. Encouraging and acknowledging correct medication administration can help reinforce good practices and build confidence in the caregiver.
Question 5 of 5
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?
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. In this case, with 20 grams of magnesium sulfate in 500 mL of solution, 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. This calculation ensures the correct dose is delivered within the specified time frame.
