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?

• A. 150 mL/hour
• B. 250 mL/hour
• C. 50 mL/hour
• D. 275 mL/hour

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. An expectant father tells the LPN/LVN he fears that his wife 'is losing her mind.' He states she is constantly rubbing her abdomen and talking to the baby, and that she actually reprimands the baby when it moves too much. What recommendation should the nurse make to this expectant father?

• A. Reassure him that these are normal reactions to pregnancy and suggest that he discuss his concerns with the childbirth education nurse.
• B. Help him understand that his wife is experiencing normal maternal behaviors and bonding with the baby, and reassure him that these actions are positive.
• C. Ask him to observe his wife's behavior carefully for the next few weeks and report any similar behavior to the nurse at the next prenatal visit.
• D. Let him know that these behaviors are part of normal maternal-fetal bonding which occur once the mother feels fetal movement.

Correct answer: D

Rationale: The father's concerns about his wife's behaviors can be addressed by explaining that behaviors like talking to the baby and responding to fetal movements are part of normal maternal-fetal bonding. These actions indicate that the mother is connecting with the baby and are positive signs of a healthy pregnancy. The nurse should reassure the father that these behaviors are common and beneficial for the mother-baby relationship during pregnancy.

3. The healthcare provider is assessing a 38-week gestation newborn infant immediately following a vaginal birth. Which assessment finding best indicates that the infant is transitioning well to extrauterine life?

• A. Positive Babinski reflex.
• B. Flexion of all four extremities.
• C. Heart rate of 220 beats/min.
• D. Cries vigorously when stimulated.

Correct answer: D

Rationale: A vigorous cry upon stimulation indicates that the newborn has good respiratory effort and is transitioning well to life outside the womb. It shows that the infant's airways are clear, and they are able to establish effective breathing, a crucial aspect of transitioning successfully to extrauterine life. Choices A, B, and C are not the best indicators of successful transition to extrauterine life. The Babinski reflex and flexion of extremities are normal neonatal reflexes and do not specifically indicate successful transition. A heart rate of 220 beats/min is abnormally high for a newborn and could indicate distress rather than a smooth transition.

4. 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?

• A. 75ml/hr
• B. 100ml/hr
• C. 50ml/hr
• D. 25ml/hr

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.

5. A 38-week primigravida who works at a desk job and sits at a computer for 8 hours each day tells the nurse that her feet have begun to swell. Which instruction would be most effective in preventing pooling of blood in the lower extremities?

• A. Wear support stockings.
• B. Reduce salt in her diet.
• C. Move about every hour.
• D. Avoid constrictive clothing.

Correct answer: C

Rationale: During pregnancy, especially in the third trimester, it is common for women to experience swelling due to decreased circulation. Encouraging the patient to move about every hour helps prevent blood pooling in the lower extremities by promoting circulation. This simple activity can help alleviate swelling and discomfort associated with prolonged sitting.
