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. A 6-week-old infant diagnosed with pyloric stenosis has recently developed projectile vomiting. Which assessment finding indicates to the nurse that the infant is becoming dehydrated?

• A. Weak cry without tears.
• B. Bulging fontanel.
• C. Visible peristaltic wave.
• D. Palpable mass in the right upper quadrant.

Correct answer: A

Rationale: In infants, a weak cry without tears is a classic sign of dehydration. Tears are produced by the lacrimal glands, and reduced tear production is a result of dehydration. This assessment finding should alert the nurse to the infant's dehydration status, requiring prompt intervention to prevent further complications.

3. 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.

4. A pregnant woman in the first trimester of pregnancy has hemoglobin of 8.6 g/dl and a hematocrit of 25.1%. What food should the nurse encourage this client to include in her diet?

• A. Carrots
• B. Chicken
• C. Yogurt
• D. Cheese

Correct answer: B

Rationale: During pregnancy, it is common for women to experience a drop in hemoglobin levels, leading to anemia. Chicken is a good dietary source of iron, which is essential for increasing hemoglobin levels. Iron from animal sources, such as chicken, is more readily absorbed by the body compared to plant-based sources. Therefore, encouraging the client to include chicken in her diet can help improve her hemoglobin levels and combat anemia.

5. The healthcare provider is reviewing the serum laboratory findings for a 5-day-old infant with congenital adrenal hyperplasia. Which laboratory result should be reported to the healthcare provider immediately?

• A. Bilirubin of 1.5 mg/dl.
• B. Glucose of 80 mg/dl.
• C. Potassium of 4.5 mEq/L.
• D. Sodium of 119 mEq/L.

Correct answer: D

Rationale: Low sodium levels in congenital adrenal hyperplasia can indicate salt-wasting crisis, which is a life-threatening emergency requiring immediate medical attention. Monitoring sodium levels is crucial to prevent complications such as dehydration and shock in these patients.
