A nurse is preparing to administer 0.45% NaCl 250 mL IV to infuse over 90 minutes. The drop factor of the manual IV tubing is 15 gtt/mL. What is the flow rate in gtt/min? (Round to the nearest whole number & fill in the blank with the numerical value only)
The Correct Answer is ["42"]
Total volume to be infused = 250 mL
Total infusion time = 90 minutes
Drop factor = 15 gtt/mL
- Calculate the flow rate in drops per minute (gtt/min):
Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Total infusion time (minutes)
= (250 mL × 15 gtt/mL) / 90 minutes
= 3750 gtt / 90 minutes
= 41.666... gtt/min
- Round to the nearest whole number:
Rounded flow rate = 42 gtt/min

Correct Answer is ["7.9"]
Explanation
Convert the ounces to a fraction of a pound:
16 ounces = 1 pound.
6 ounces = 6/16 pound
= 0.375 pound
Total weight in pounds = 17 pounds + 0.375 pound = 17.375 pounds
1 kg= 2.2 pounds
Weight in kg = 17.375 pounds / 2.2 pounds/kg
=7.8977 kg
Round to the nearest tenth:
Rounded weight = 7.9 kg
Correct Answer is C
Explanation
A. "Opioid-induced constipation typically resolves on its own after a few weeks of treatment.": This is incorrect. Unlike other opioid side effects such as nausea or sedation, constipation does not typically resolve over time. It often persists and requires proactive management throughout opioid therapy.
B. "Avoid physical activity to prevent exacerbating your back pain.": While activity should be adjusted to the patient’s condition, light physical activity like walking actually helps stimulate bowel function. Complete avoidance of movement can worsen constipation.
C. "Start taking stool softeners along with your opioid medication.": This is the most appropriate advice. Prophylactic use of stool softeners or stimulant laxatives is recommended when initiating opioid therapy, as constipation is a nearly universal side effect due to slowed gastrointestinal motility.
D. "You should wait to see if constipation develops before taking any specific measures.": Waiting for constipation to develop can lead to discomfort and complications like fecal impaction. Preventive strategies should be started as soon as opioid treatment begins.
