HESI Maternity Test Bank Questions

Question 1 of 5

Twenty minutes after a continuous epidural anesthetic is administered, a laboring client's blood pressure drops from 120/80 to 90/60. What action should the healthcare provider take?

Correct Answer: C

Rationale: Placing the woman in a lateral position is the appropriate action to improve venous return and cardiac output, helping to stabilize the blood pressure. This position can alleviate pressure on the inferior vena cava, reducing the risk of hypotension associated with epidural anesthesia.

Question 2 of 5

What action should be implemented when preparing to measure the fundal height of a pregnant client?

Correct Answer: A

Rationale: Having the client empty her bladder before measuring the fundal height is essential to ensure an accurate measurement. A full bladder can impact the fundal height measurement by displacing the uterus and affecting the accuracy of the assessment.

Question 3 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.

Question 4 of 5

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

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.

Question 5 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.
