1. A healthcare professional is preparing to administer magnesium sulfate 2 g/hr IV to a client who is in preterm labor. Available is 20 g of magnesium sulfate in 500 mL of dextrose 5% in water (D5W). How many mL/hr should the IV infusion pump be set to administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 60
• B. 30
• C. 50
• D. 80

Correct answer: C

Rationale: To administer magnesium sulfate 2 g/hr IV, the healthcare professional should set the IV infusion pump to administer 50 mL/hr. The calculation is as follows: 20 g / 500 mL = 2 g / X mL, X = 50 mL/hr. Choice A (60 mL/hr) is incorrect as it does not match the calculated rate. Choice B (30 mL/hr) is incorrect as it is half of the calculated rate. Choice D (80 mL/hr) is incorrect as it is higher than the calculated rate.

2. A client at 8 weeks of gestation with iron deficiency anemia is prescribed iron supplements. Which beverage should the nurse reinforce the client to take the supplements with for better absorption?

• A. Ice water
• B. Low-fat or whole milk
• C. Tea or coffee
• D. Orange juice

Correct answer: D

Rationale: The correct answer is 'Orange juice.' Orange juice is recommended to be taken with iron supplements because vitamin C present in orange juice enhances iron absorption, improving the effectiveness of the supplement. It is essential to take iron supplements with a source of vitamin C to optimize iron absorption and address iron deficiency anemia. Ice water (Choice A), low-fat or whole milk (Choice B), and tea or coffee (Choice C) are not ideal choices to take with iron supplements as they do not contain vitamin C, which is crucial for enhancing iron absorption.

3. When calculating the Apgar score of a newborn at 1 minute after delivery, which of the following findings would result in a score of 6?

• A. 4
• B. 5
• C. 6
• D. 7

Correct answer: C

Rationale: The Apgar score is calculated based on five parameters: heart rate, respiratory effort, muscle tone, reflex irritability, and color. In this case, the newborn's findings at 1 minute after delivery indicate a heart rate >100/min (2 points), slow, weak cry (1 point), some flexion of extremities (1 point), grimace in response to suctioning (1 point), and body pink with blue extremities (1 point). Adding these points together results in a total Apgar score of 6, reflecting the newborn's initial assessment for their overall well-being. Choice A (4) is too low based on the given findings, while Choice B (5) is also lower than the correct score of 6. Choice D (7) is too high as it would require additional findings to reach that score.

4. While assisting with the care of a client in active labor, a nurse observes clear fluid and a loop of pulsating umbilical cord outside the client's vagina. Which of the following actions should the nurse perform first?

• A. Place the client in the Trendelenburg position
• B. Apply finger pressure to the presenting part
• C. Administer oxygen at 10 L/min via a non-rebreather
• D. Call for assistance

Correct answer: D

Rationale: In the scenario of umbilical cord prolapse during labor, the nurse should first call for assistance. Umbilical cord prolapse is a critical obstetric emergency that requires immediate attention and skilled assistance. Calling for help ensures that additional support is on the way to provide prompt intervention. Placing the client in the Trendelenburg position (Choice A) is no longer recommended as it may worsen the situation. Applying finger pressure to the presenting part (Choice B) can further compress the cord. Administering oxygen (Choice C) is important but should come after addressing the prolapsed cord.

5. A healthcare provider is assessing a newborn 1 hr after birth. Which of the following respiratory rates is within the expected reference range for a newborn?

• A. 22/min
• B. 48/min
• C. 100/min
• D. 110/min

Correct answer: B

Rationale: The expected respiratory rate for a newborn is between 30 to 60 breaths per minute. A rate of 48 breaths per minute falls within this range, indicating normal respiratory function for a newborn. Choice A (22/min) is below the expected range, Choices C (100/min) and D (110/min) are above the expected range for a newborn's respiratory rate.
