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?

• 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.

2. A 28-year-old client in active labor complains of cramps in her leg. What intervention should be implemented?

• A. Massage the calf and foot.
• B. Extend the leg and dorsiflex the foot.
• C. Lower the leg off the side of the bed.
• D. Elevate the leg above the heart.

Correct answer: B

Rationale: During active labor, if a client complains of leg cramps, extending the leg and dorsiflexing the foot can help relieve the muscle cramps by stretching the affected muscles. This intervention promotes circulation and can alleviate discomfort associated with leg cramps.

3. A breastfeeding infant, screened for congenital hypothyroidism, is found to have low levels of thyroxine (T4) and high levels of thyroid-stimulating hormone (TSH). What is the best explanation for this finding?

• A. The thyroxine level is low because the TSH level is high.
• B. High thyroxine levels do not normally occur in breastfeeding infants.
• C. The thyroid gland does not produce normal levels of thyroxine for several weeks after birth.
• D. The TSH is high because of the low production of T4 by the thyroid.

Correct answer: D

Rationale: High TSH and low T4 levels indicate that the thyroid gland is not producing enough hormones, which is a sign of congenital hypothyroidism. In this case, the high TSH is a compensatory response by the body to stimulate the thyroid to produce more T4. Choice A is incorrect because TSH does not directly affect T4 levels; rather, it is the other way around where low T4 levels lead to high TSH levels. Choice B is incorrect because high thyroxine levels are not expected in congenital hypothyroidism. Choice C is incorrect as the thyroid gland should be producing normal levels of thyroxine shortly after birth, making this explanation unlikely in the context of congenital hypothyroidism.

4. The client is 30 weeks pregnant and experiencing preterm labor. Which medication should the nurse anticipate administering to promote fetal lung maturity?

• A. Betamethasone (Celestone).
• B. Magnesium sulfate.
• C. Terbutaline (Brethine).
• D. Ampicillin.

Correct answer: A

Rationale: Betamethasone (Celestone) is the medication of choice to promote fetal lung maturity in cases of preterm labor. It helps accelerate surfactant production in the fetal lungs, reducing the risk of respiratory distress syndrome. Administering betamethasone to the mother can improve the baby's lung function and overall outcome if preterm birth occurs. Magnesium sulfate is commonly used to prevent seizures in preeclampsia or eclampsia. Terbutaline is a tocolytic agent used to suppress preterm labor contractions. Ampicillin is an antibiotic used for various bacterial infections but does not promote fetal lung maturity.

5. Insulin therapy is initiated for a 12-year-old child who is admitted with diabetic ketoacidosis (DKA). Which action is most important for the nurse to include in the child’s plan of care?

• A. Monitor serum glucose for adjustment in the infusion rate of regular insulin (Novolin R).
• B. Determine the child’s compliance schedule for subcutaneous NPH insulin (Humulin N).
• C. Demonstrate to the parents how to program an insulin pen for daily glucose regulation.
• D. Consult with the healthcare provider about the use of insulin detemir (Levemir Flex Pen).

Correct answer: A

Rationale: In managing diabetic ketoacidosis (DKA), monitoring serum glucose levels is crucial to adjust the infusion rate of regular insulin effectively. This helps in controlling blood glucose levels and preventing complications associated with DKA. Close monitoring and adjustments based on glucose levels are essential for the successful management of DKA. Choice B is incorrect as it focuses on a different type of insulin and compliance schedule without addressing the immediate needs of managing DKA. Choice C is not the priority action and involves educating parents on a different method of insulin administration. Choice D is also not the most important action as it suggests consulting with the healthcare provider about a different type of insulin rather than focusing on immediate glucose monitoring for insulin adjustment in DKA management.
