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. During a prenatal visit, the nurse discusses with a client the effects of smoking on the fetus. When compared with nonsmokers, mothers who smoke during pregnancy tend to produce infants who have

• A. lower Apgar scores.
• B. lower birth weights.
• C. respiratory distress.
• D. a higher rate of congenital anomalies.

Correct answer: B

Rationale: Smoking during pregnancy is associated with intrauterine growth restriction, leading to lower birth weights. This occurs due to the harmful effects of smoking on fetal development, which can result in reduced nutrient and oxygen supply to the fetus, impacting its overall growth and leading to lower birth weights. Choices A, C, and D are incorrect as smoking during pregnancy primarily affects fetal growth and development, leading to lower birth weights rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.

3. The healthcare provider is preparing to administer methylergonovine maleate (Methergine) to a postpartum client. Based on what assessment finding should the healthcare provider withhold the drug?

• A. Respiratory rate of 22 breaths/min
• B. A large amount of lochia rubra
• C. Blood pressure 149/90
• D. Positive Homan’s sign

Correct answer: C

Rationale: A blood pressure of 149/90 is an indication to withhold Methergine due to its potential to further increase blood pressure. Methergine is a medication that can cause vasoconstriction, leading to elevated blood pressure. In this case, administering Methergine could exacerbate the elevated blood pressure, posing a risk to the patient. Therefore, it is crucial to withhold the medication in the presence of hypertension to prevent adverse effects. The other options are not directly related to the administration of Methergine. A respiratory rate of 22 breaths/min is within the normal range. A large amount of lochia rubra may indicate normal postpartum bleeding. A positive Homan’s sign is associated with deep vein thrombosis, which is not a contraindication for administering Methergine.

4. The healthcare provider receives a newborn within the first minutes after vaginal delivery and intervenes to establish adequate respirations. What priority issue should the healthcare provider address to ensure the newborn's survival?

• A. Heat loss.
• B. Fluid balance.
• C. Bleeding tendencies.
• D. Hypoglycemia.

Correct answer: A

Rationale: Corrected Rationale: Immediately after birth, newborns are at high risk for heat loss, which can lead to cold stress and associated complications. Maintaining thermal regulation is crucial to prevent hypothermia and ensure the newborn's survival. By addressing heat loss as a priority issue, the healthcare provider can help stabilize the newborn's temperature and support overall well-being. Choices B, C, and D are not the priority issues immediately after birth. While fluid balance, bleeding tendencies, and hypoglycemia are important considerations in newborn care, heat loss is the primary concern right after delivery to prevent complications related to thermal regulation.

5. The healthcare provider is assessing a 38-week gestation newborn infant immediately following a vaginal birth. Which assessment finding best indicates that the infant is transitioning well to extrauterine life?

• A. Positive Babinski reflex.
• B. Flexion of all four extremities.
• C. Heart rate of 220 beats/min.
• D. Cries vigorously when stimulated.

Correct answer: D

Rationale: A vigorous cry upon stimulation indicates that the newborn has good respiratory effort and is transitioning well to life outside the womb. It shows that the infant's airways are clear, and they are able to establish effective breathing, a crucial aspect of transitioning successfully to extrauterine life. Choices A, B, and C are not the best indicators of successful transition to extrauterine life. The Babinski reflex and flexion of extremities are normal neonatal reflexes and do not specifically indicate successful transition. A heart rate of 220 beats/min is abnormally high for a newborn and could indicate distress rather than a smooth transition.
