Nursing Elites

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. At 20 weeks gestation, a client is scheduled for an ultrasound. In preparing the client for the procedure, the nurse should explain that the primary reason for conducting this diagnostic study is to obtain which information?

• A. Sex and size of the fetus.
• B. Chromosomal abnormalities.
• C. Fetal growth and gestational age.
• D. Lecithin-sphingomyelin ratio.

Correct answer: C

Rationale: The primary reason for an ultrasound at 20 weeks gestation is to assess fetal growth, gestational age, and anatomical development. This evaluation helps ensure the fetus is developing appropriately and can detect any potential issues that may require intervention. Choices A, B, and D are incorrect because at 20 weeks, the primary focus of the ultrasound is not to determine the sex of the fetus, detect chromosomal abnormalities, or assess the lecithin-sphingomyelin ratio. While these factors may be evaluated in pregnancy, they are not the primary reasons for an ultrasound at 20 weeks gestation.

3. Immediately after birth, a newborn infant is suctioned, dried, and placed under a radiant warmer. The infant has spontaneous respirations, and the nurse assesses an apical heart rate of 80 beats/minute and respirations of 20 breaths/minute. What action should the nurse take next?

• A. Initiate positive pressure ventilation.
• B. Intervene after the one-minute Apgar assessment.
• C. Initiate CPR on the infant.
• D. Assess the infant's blood glucose level.

Correct answer: A

Rationale: A heart rate below 100 bpm in a newborn indicates bradycardia and requires intervention. Positive pressure ventilation should be initiated to improve oxygenation and help increase the infant's heart rate. This intervention is crucial to support the newborn's transition to extrauterine life and prevent further complications.

4. A 36-week primigravida is admitted to labor and delivery with severe abdominal pain and bright red vaginal bleeding. Her abdomen is rigid and tender to touch. The fetal heart rate (FHR) is 90 beats/minute, and the maternal heart rate is 120 beats/minute. What action should the nurse implement first?

• A. Alert the neonatal team and prepare for neonatal resuscitation
• B. Notify the healthcare provider from the client’s bedside
• C. Obtain written consent for an emergency cesarean section
• D. Draw a blood sample for stat hemoglobin and hematocrit

Correct answer: B

Rationale: In this scenario, the priority action for the nurse is to notify the healthcare provider from the client's bedside. The clinical presentation of severe abdominal pain, bright red vaginal bleeding, rigid and tender abdomen, along with fetal bradycardia (FHR 90 bpm) and maternal tachycardia (120 bpm) indicates an urgent need for medical intervention. Notifying the healthcare provider promptly allows for immediate assessment and decision-making to address the critical condition and ensure timely and appropriate management for both the mother and fetus.

5. Which intervention is most helpful in relieving postpartum uterine contractions or 'afterpains'?

• A. Lying prone with a pillow on the abdomen.
• B. Using a breast pump.
• C. Massaging the abdomen.
• D. Giving oxytocic medications.

Correct answer: A

Rationale: Lying prone with a pillow on the abdomen is the most helpful intervention in relieving postpartum uterine contractions or 'afterpains.' This position provides counter-pressure and support to the uterus, helping to alleviate discomfort and promote uterine involution. Choice B, using a breast pump, is not effective in relieving afterpains as it focuses on milk expression. Massaging the abdomen (Choice C) may help with discomfort but does not provide the same level of support as lying prone with a pillow. Giving oxytocic medications (Choice D) is not typically the first-line intervention for afterpains unless there are specific medical indications.
