A nurse is preparing to administer Lactated Ringer's 1000 mL IV to infuse over 6 hours. The drop factor of the manual IV tubing is 10 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 ["28"]
Total volume to be infused = 1000 mL
Infusion time in hours = 6 hours
Minutes per hour = 60 minutes/hour
Total infusion time in minutes = 6 hours × 60 minutes/hour = 360 minutes
Drop factor = 10 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)
= (1000 mL × 10 gtt/mL) / 360 minutes
= 10000 gtt / 360 minutes
= 27.777... gtt/min
- Round to the nearest whole number:
= 28 gtt/min

Correct Answer is ["2"]
Explanation
Desired dose rate = 0.6 mg/hr
Available concentration = 50 mg / 150 mL
- Calculate the concentration in mg/mL:
Concentration (mg/mL) = 50 mg / 150 mL
= 1/3 mg/mL
- Calculate the flow rate in mL/hr:
Flow rate (mL/hr) = Desired dose rate (mg/hr) / Concentration (mg/mL)
= 0.6 mg/hr / (1/3 mg/mL)
= 0.6 × 3 mL/hr
Flow rate (mL/hr) = 1.8 mL/hr
- Round to the nearest whole number:
= 2 mL/hr
Correct Answer is A
Explanation
A. "I should report a persistent cough to my provider.": A dry, persistent cough is a common side effect of ACE inhibitors like Lisinopril. Reporting this symptom is important, as the provider may consider switching to another class of antihypertensives if it becomes bothersome.
B. "I should take this medication as needed.": Lisinopril must be taken consistently every day to manage blood pressure effectively. Taking it only when symptoms are present is inappropriate and can lead to poor control and serious complications.
C. "I should expect to have facial swelling when taking this medication.": Facial swelling (angioedema) is a serious and potentially life-threatening adverse effect, not something to expect or tolerate. If it occurs, the medication should be stopped and medical help sought immediately.
D. "I should increase my intake of potassium-rich foods.": Lisinopril can increase serum potassium levels, leading to hyperkalemia. Clients should be advised to avoid excessive potassium intake and may need periodic lab monitoring.
