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).

A loading dose of terbutaline (Brethine) 250 mcg IV is prescribed for a client in preterm labor. Brethine 20 mg is added to 1,000 mL of D5W. How many milliliters of the solution should the nurse administer?
- A. 45
- B. 15 mL
- C. 4
- D. 13
Correct Answer: D
Rationale: To calculate the amount of terbutaline to administer, first convert the dose to the same unit. 250 mcg = 0.25 mg. Next, set up a proportion: 20 mg is to 1000 mL as 0.25 mg is to X mL. Cross multiply and solve for X: 20 X = 0.25 1000. X = (0.25 1000) / 20 = 12.5 mL. Therefore, the nurse should administer 13 mL of the solution.

An infant with tetralogy of Fallot becomes acutely cyanotic and hyperneic. Which action should the nurse implement first?
- A. Place the infant in a knee-chest position.
- B. Administer morphine sulfate.
- C. Start intravenous fluids.
- D. Provide 100% oxygen by face mask.
Correct Answer: A
Rationale: In a tetralogy of Fallot situation, placing the infant in a knee-chest position is the initial priority to help increase systemic vascular resistance, which reduces the right-to-left shunt and improves oxygenation. This position can assist in optimizing oxygen levels before considering other interventions.

A new mother calls the nurse stating that she wants to start feeding her 6-month-old child something besides breast milk, but is concerned that the infant is too young to start eating solid foods. How should the nurse respond?
- A. Advise the mother to wait at least another month before starting any solid foods.
- B. Instruct the mother to offer a few spoons of 2 or 3 pureed fruits at each meal.
- C. Reassure the mother that the infant is old enough to eat iron-fortified cereal.
- D. Encourage the mother to schedule a developmental assessment of the infant.
Correct Answer: C
Rationale: At 6 months, infants are generally ready to start eating iron-fortified cereals as their iron stores begin to deplete. Introducing iron-fortified cereals at this age helps meet the infant's nutritional needs, particularly for iron, which becomes deficient as the infant's iron reserves diminish. It is a safe and appropriate first food to introduce to infants around 6 months of age, along with continued breastfeeding or formula feeding.
