1. 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. Choice A is incorrect as it does not reflect the correct calculation. Choice B is incorrect as it does not consider the accurate conversion and calculation. Choice C is incorrect as it is not the result of the correct proportion calculation.
2. A client at 32 weeks gestation is hospitalized with severe pregnancy-induced hypertension (PIH), and magnesium sulfate is prescribed to control the symptoms. Which assessment finding indicates the therapeutic drug level has been achieved?
- A. 4+ reflexes
- B. Urinary output of 50 ml per hour
- C. A decrease in respiratory rate from 24 to 16
- D. A decreased body temperature
Correct answer: C
Rationale: A decrease in respiratory rate from 24 to 16 indicates that magnesium sulfate is effectively reducing central nervous system irritability, a desired therapeutic effect. This decrease in respiratory rate signifies that the drug has reached a therapeutic level to control symptoms of severe pregnancy-induced hypertension. Choices A, B, and D are incorrect because 4+ reflexes, urinary output, and body temperature are not direct indicators of achieving a therapeutic level of magnesium sulfate for controlling PIH symptoms.
3. A client who is receiving oxytocin to augment early labor begins to experience tachysystolic tetanic contractions with variable fetal heart decelerations. Which action should the nurse implement?
- A. Turn off the oxytocin infusion.
- B. Reposition the fetal monitor transducers.
- C. Decrease the rate of the oxytocin infusion.
- D. Alert the charge nurse about the patient's condition.
Correct answer: A
Rationale: When a client experiences tachysystolic tetanic contractions with variable fetal heart decelerations, indicating uterine hyperstimulation, the priority action is to turn off the oxytocin infusion. This step aims to reduce uterine activity, which can compromise fetal oxygenation and lead to adverse outcomes.
4. The nurse is caring for a postpartum client who is complaining of severe pain and a feeling of pressure in her perineum. Her fundus is firm, and she has a moderate lochial flow. On inspection, the nurse finds that a perineal hematoma is beginning to form. Which assessment finding should the nurse obtain first?
- A. Urinary output and fluid intake.
- B. Hemoglobin and hematocrit.
- C. Abdominal contour and bowel sounds.
- D. Heart rate and blood pressure.
Correct answer: D
Rationale: In a postpartum client with a perineal hematoma, assessing heart rate and blood pressure is crucial as it can help determine the client's circulatory status. A perineal hematoma has the potential to cause significant blood loss leading to hypovolemia. Monitoring vital signs like heart rate and blood pressure can provide immediate information on the client's hemodynamic stability and guide further interventions if needed.
5. After breastfeeding for 10 minutes at each breast, a new mother calls the nurse to the postpartum room to help change the newborn's diaper. As the mother begins the diaper change, the newborn spits up the breast milk. What action should the nurse implement first?
- A. Wipe away the spit-up and assist the mother with the diaper change.
- B. Sit the newborn upright and burp by rubbing or patting the upper back.
- C. Place the newborn in a position with the head lower than the feet.
- D. Turn the newborn to the side and use bulb suction for the mouth and nares.
Correct answer: B
Rationale: After a newborn spits up breast milk following feeding, the priority action for the nurse is to sit the newborn upright and burp by rubbing or patting the upper back. This position helps release trapped air and reduces the likelihood of further spit-up or aspiration. It is essential to address this first to prevent potential complications and ensure the newborn's comfort and safety.
