1. A 34-week primigravida woman with preeclampsia is receiving Lactated Ringer’s 500ml with magnesium sulfate 20 grams at the rate of 3g/hr. How many ml/hr should the nurse program the infusion pump?

Correct answer: A

Rationale: To calculate the infusion rate, divide the total quantity to be infused (500ml) by the total time (1 hour) which equals 500ml/hr. Since the magnesium sulfate is being given at 3g/hr, and 1g of magnesium sulfate is in 5ml of solution, the rate will be 3g/hr x 5ml/g = 15ml/hr. Therefore, the total infusion rate should be 500ml/hr + 15ml/hr = 515ml/hr. Hence, the nurse should program the infusion pump to deliver 75ml/hr (515ml/hr total - 500ml/hr Lactated Ringer's rate). This choice is correct because it accounts for both the Lactated Ringer's and magnesium sulfate rates. Choice B, 100ml/hr, is incorrect as it does not consider the additional magnesium sulfate infusion rate. Choice C, 50ml/hr, is incorrect because it does not account for the magnesium sulfate infusion. Choice D, 25ml/hr, is incorrect as it is too low and does not consider the magnesium sulfate being infused concurrently.

2. A 6-year-old with heart failure (HF) gained 2 pounds in the last 24 hours. Which intervention is more important for the nurse to implement?

Correct answer: C

Rationale: Assessing bilateral lung sounds is crucial in this scenario as it can provide essential information about potential fluid accumulation in the lungs, indicating worsening heart failure. This assessment can guide immediate interventions to prevent further deterioration in the patient's condition.

3. Upon admission to the prenatal clinic, a 23-year-old woman informs the nurse that her last menstrual period began on February 15, and that previously her periods were regular. Her pregnancy test is positive. What is this client's expected date of delivery (EDD)?

Correct answer: A

Rationale: To determine the expected date of delivery (EDD) using Nägele's rule, add 7 days to the first day of the last menstrual period (LMP) which is February 15, resulting in February 22. Then, subtract 3 months from February 22, which gives November 22 as the estimated due date.

4. 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. Providing a quiet environment with subdued lighting may be beneficial for the client's comfort but is not the highest priority in this situation. Assessing deep tendon reflexes every 4 hours is important when administering magnesium sulfate, but it is not the highest priority compared to having calcium gluconate available. Inserting a Foley catheter with a urimeter to monitor hourly output is not the highest priority when preparing to administer magnesium sulfate in this scenario.

5. A client addicted to heroin and newly pregnant asks a nurse about ensuring her baby's health while on methadone. What should the nurse advise?

Correct answer: C

Rationale: Initiating prenatal care promptly is essential for monitoring the well-being of both the mother and the fetus, particularly in high-risk pregnancies involving substance use. Early prenatal care allows for timely interventions, education, and support to promote a healthier pregnancy and birth outcomes. Choice A is incorrect because while group therapy may be beneficial, initiating prenatal care is more crucial at this stage. Choice B is incorrect as abrupt discontinuation of methadone can be harmful and should be managed under medical supervision. Choice D is incorrect as genetic testing is not the immediate priority in this scenario.
