A client is ordered digoxin 0.25mg po. daily. On hand is a liquid in a dropper bottle labeled 500mcg/10mL. How many milliliters will be administered?
The Correct Answer is ["5"]
Given:
Desired dose: Digoxin 0.25 mg PO daily
Available concentration: Digoxin 500 mcg/10 mL
To find:
Volume to administer (in mL)
Step 1: Convert desired dose to micrograms
We know that 1 milligram (mg) is equal to 1000 micrograms (mcg). Therefore, to convert the desired dose from mg to mcg, we multiply by 1000:
Desired dose (mcg) = Desired dose (mg)x 1000
Desired dose (mcg) = 0.25 mg x 1000 = 250 mcg
Step 2: Set up the proportion
We can use the following proportion to solve the problem:
(Desired dose) / (Available concentration) = Volume to administer
Step 3: Substitute the values
Plugging in the given values, we get:
(250 mcg) / (500 mcg/10 mL) = Volume to administer
Step 4: Simplify
To simplify, we can invert the denominator and multiply:
(250 mcg) x (10 mL / 500 mcg) = Volume to administer
The "mcg" units cancel out, leaving us with:
(250 x 10 mL) / 500 = Volume to administer
Step 5: Calculate
Performing the multiplication and division, we get:
2500/ 500 = Volume to administer
5 mL = Volume to administer

Correct Answer is ["33"]
Explanation
Given:
Total volume to infuse: 100 mL
Infusion time: 60 minutes
Drop factor of tubing: 20 gtt/mL
To find:
Drip rate (gtt/min)
Step 1: Calculate the total number of drops
Total drops = Total volume x Drop factor
Total drops = 100 mL x 20 gtt/mL = 2000 gtt
Step 2: Calculate the drip rate
Drip rate = Total drops / Infusion time in minutes
Drip rate = 2000 gtt / 60 minutes = 33.33 gtt/min
Step 3: Round to the nearest whole number
33 gtt/min.
Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"D"}
Explanation
Uterine rupture: A client in active labor with a history of prior vaginal birth is at risk for uterine rupture, particularly when experiencing intense contractions and increasing pelvic pressure. While previous vaginal delivery lowers the risk compared to a history of cesarean section, prolonged or strong contractions can still contribute to uterine rupture, especially if there is an undiagnosed uterine scar or excessive uterine stress.
Increasing pelvic pressure: The client reports increasing pelvic pressure despite receiving an epidural, which can be a sign of impending uterine rupture. While pelvic pressure is expected during labor, a sudden or intense sensation, particularly in the setting of strong contractions and rapid cervical dilation, warrants close monitoring.
