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 10-year-old is admitted to the orthopedic unit with a diagnosis of slipped femoral capital epiphysis (SFCE). What focus should the nurse include in this child’s plan of care?

Correct answer: B

Rationale: In the case of slipped femoral capital epiphysis, surgical intervention is often required. Post-surgery care is crucial to prevent complications such as infection and ensure proper healing. This care includes monitoring and managing pin and incision sites for signs of infection, promoting wound healing, and preventing postoperative complications. The focus on pin and incision care is essential for the child's recovery and overall well-being.

3. The nurse is measuring the frontal occipital circumference (FOC) of a 3-month-old infant, notes that the FOC has increased by 5 cm since birth, and observes that the child’s head appears large in relation to body size. Which action is most important for the nurse to take next?

Correct answer: C

Rationale: Palpating the anterior fontanel for tension and bulging is essential to assess for increased intracranial pressure, which could be indicated by the enlarged head circumference. This assessment can help identify potential neurological issues that need prompt attention.

4. Which physical assessment data should the nurse consider a normal finding for a primigravida client who is 12 hours postpartum?

Correct answer: C

Rationale: A pulse rate of 56 bpm is a normal finding for a primigravida client who is 12 hours postpartum. Bradycardia (pulse rate 50-70 bpm) can be a normal postpartum occurrence due to increased stroke volume and decreased cardiac output after delivery. Unilateral lower leg pain and saturating two perineal pads per hour are not normal findings and require further assessment. A soft, spongy fundus could indicate uterine atony, which is abnormal postpartum.

5. 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.
