A client who is scheduled for induction of labor receives a prescription for oxytocin 2 milliunits/min intravenously (IV). The IV bag contains oxytocin 20 units in lactated Ringer’s 1 liter.

How many mL/hour should the nurse program the infusion pump to deliver? .

Answer and Explanation

The Correct Answer is ["6"]

The correct answer is calculated as follows:

Step 1: Identify the total amount of oxytocin in the IV bag. The bag contains 20 units of oxytocin in 1 liter (or 1000 mL) of lactated Ringer’s solution.

Step 2: Convert the oxytocin units to milliunits. 1 unit = 1000 milliunits, so 20 units = 20,000 milliunits.

Step 3: Calculate the concentration of the oxytocin solution in milliunits/mL. Divide the total amount of oxytocin in milliunits by the total volume of the solution in mL.

So, 20,000 milliunits ÷ 1000 mL = 20 milliunits/mL.

Step 4: Calculate the infusion rate in mL/hour. The prescription is for an infusion rate of 2 milliunits/min. Since the concentration of the solution is 20 milliunits/mL, we divide the prescribed rate by the concentration to get the rate in mL/min. So, 2 milliunits/min ÷ 20 milliunits/mL = 0.1 mL/min.

Step 5: Convert the infusion rate to mL/hour. Multiply the rate in mL/min by the number of minutes in an hour. So, 0.1 mL/min × 60 min/hour = 6 mL/hour. Therefore, the nurse should program the infusion pump to deliver 6 mL/hour.

Correct Answer is A

Explanation

Choice A rationale

A postpartum client experiencing severe pain and a sensation of pressure in her perineum, along with the formation of a perineal hematoma, is in a potentially serious situation. The nurse should first assess the client’s heart rate and blood pressure. This is because a perineal hematoma can lead to significant blood loss, which could cause changes in these vital signs.

Choice B rationale

While monitoring urinary output and IV fluid intake can be important in the overall assessment of a postpartum client, these are not the most immediate concerns when a perineal hematoma is forming.

Choice C rationale

Checking hemoglobin and hematocrit levels can provide information about the client’s blood volume and potential blood loss. However, this would likely be done after initial vital signs are assessed and stabilized.

Choice D rationale

Assessing abdominal contour and bowel sounds would not be the most immediate concern in this situation. These assessments would be more relevant if there were concerns about postpartum complications related to the client’s gastrointestinal system.

A. Initiate phototherapy for the newborn. B. Review the mother’s medical records for blood type and Rh factor. C. Measure bilirubin levels using transcutaneous bilirubinometry. D. Evaluate the results of the cord blood Coomb’s test.

Correct Answer is C

Explanation

Choice A rationale

Initiating phototherapy for the newborn is a treatment for jaundice, not a diagnostic step. It would be premature to start this treatment without confirming the diagnosis and assessing the severity of jaundice.

Choice B rationale

Reviewing the mother’s medical records for blood type and Rh factor can be useful in cases where Rh incompatibility is suspected. However, this would not be the immediate next step when observing a yellow tint on the baby’s skin.

Choice C rationale

Measuring bilirubin levels using transcutaneous bilirubinometry is the appropriate next step when jaundice is suspected in a newborn. This non-invasive test can quickly and accurately

measure bilirubin levels, helping to determine the severity of jaundice and guide treatment decisions.

Choice D rationale

Evaluating the results of the cord blood Coomb’s test can help identify cases of immune- mediated hemolytic disease of the newborn, a potential cause of neonatal jaundice. However, this would not typically be the first step taken when jaundice is observed.
