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?

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. A pregnant woman comes to the prenatal clinic for an initial visit. In reviewing her childbearing history, the client indicates that she has delivered premature twins, one full-term baby, and has had no abortions. Which GTPAL should the LPN/LVN document in this client's record?

Correct answer: D

Rationale: The correct GTPAL for this client is 3-1-1-0-3. G (Gravida) is 3, indicating a total of 3 pregnancies. T (Term) is 1, representing 1 full-term delivery. P (Preterm) is 1, not 2 as mentioned in the question, as twins count as one pregnancy event. A (Abortions) is 0, and L (Living) is 3, indicating 3 living children (twins count as 1). Therefore, the correct answer is 3-1-1-0-3.

3. After administering the varicella vaccine to a 5-year-old child, which instruction should the nurse provide the child’s parent?

Correct answer: D

Rationale: After receiving the varicella vaccine, applying a cool pack to the injection site can help reduce discomfort. This intervention is a simple and effective way to manage local reactions at the site of the vaccination, providing comfort to the child and potentially reducing swelling or pain. Choices A, B, and C are incorrect because chewable children’s aspirin is not typically recommended after vaccination, keeping the child home is not necessary unless advised by a healthcare provider, and monitoring fever alone is not the primary instruction post-varicella vaccination.

4. While caring for a laboring client on continuous fetal monitoring, the nurse notes a fetal heart rate pattern that falls and rises abruptly with a 'V' shaped appearance. What action should the nurse take first?

Correct answer: A

Rationale: In cases of fetal heart rate patterns showing abrupt falls and rises with a 'V' shaped appearance, it indicates possible cord compression. Changing the maternal position, such as moving the mother onto her side, can relieve the pressure off the cord and help improve fetal oxygenation, making it the priority intervention to address the decelerations.

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.
