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.

A 4-week-old premature infant has been receiving epoetin alfa (Epogen) for the last three weeks. Which assessment finding indicates to the healthcare provider that the drug is effective?
- A. Slowly increasing urinary output over the last week.
- B. Respiratory rate changes from the 40s to the 60s.
- C. Changes in apical heart rate from the 180s to the 140s.
- D. Change in indirect bilirubin from 12 mg/dl to 8 mg/dl.
Correct Answer: C
Rationale: The correct answer is C. Epoetin alfa stimulates erythropoiesis, leading to an increase in red blood cell production and improving oxygen-carrying capacity. As the oxygenation status improves, there is a reduction in heart rate. Therefore, changes in apical heart rate from the 180s to the 140s indicate that the drug is effective.
The caregiver observes a mother giving her 11-month-old ferrous sulfate (iron drops), followed by 2 ounces of orange juice. What should the caregiver do next?
- A. Tell the mother to follow the iron drops with infant formula instead of orange juice.
- B. Suggest placing the iron drops in the orange juice and then feeding the infant.
- C. Instruct the mother to feed the infant nothing for 30 minutes after giving the iron drops.
- D. Give the mother positive feedback about the way she administered the medication.
Correct Answer: D
Rationale: The high vitamin C content in orange juice aids in the absorption of iron. Providing positive feedback to the mother for administering the iron drops with orange juice is appropriate as it enhances iron absorption, benefiting the infant. Encouraging and acknowledging correct medication administration can help reinforce good practices and build confidence in the caregiver.

The healthcare provider is preparing to administer magnesium sulfate to a laboring client whose blood pressure has increased from 110/60 mmHg to 140/90 mmHg. Which action is the highest priority?
- A. Provide a quiet environment with subdued lighting.
- B. Have calcium gluconate immediately available.
- C. Assess deep tendon reflexes (DTRs) every 4 hours.
- D. Insert a Foley catheter with a urimeter to monitor hourly output.
Correct Answer: B
Rationale: Having calcium gluconate readily available is crucial when administering magnesium sulfate, as it serves as the antidote in case of magnesium toxicity. Magnesium sulfate can lead to respiratory depression and cardiac arrest in cases of overdose or toxicity, making the prompt availability of calcium gluconate essential for immediate administration to counteract these effects.
