A client receives a prescription for dextrose 5% in water 500 mL IV to be infused over 4 hours.
The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the
infusion? (Enter numerical value only. If rounding is required, round to the nearest whole
number.)
Hide Correct Answer and Explanation
31
To find out how many gtt/min the nurse should regulate the infusion;
We can use the following formula:
Flow rate (gtt/min) = Total volume (mL) / Time (min) × Drop factor (gtt/mL)
Given:
Total volume = 500 mL
Time = 4 hours = 240 minutes (since 1 hour = 60 minutes)
Drop factor = 15 gtt/mL
Substituting the given values into the formula:
Flow rate (gtt/min) =500 mL/240 min ×15 gtt/mL
After performing the calculation, we find that the flow rate equals 31.25 gtt/min.
So, the nurse should regulate the infusion to 31 gtt/min (rounded to the nearest whole
number)
37.5
Determine the concentration of magnesium sulfate in the IV bag:
The IV bag contains 4 grams (4000 mg) of magnesium sulfate in 500 mL.
Concentration = 4000 mg / 500 mL = 8 mg/mL
Determine the prescribed infusion rate:
The prescription is for 300 mg/hour.
Calculate the infusion rate in mL/hour:
Infusion rate (mL/hour) = Prescribed dose (mg/hour) / Concentration (mg/mL)
Infusion rate (mL/hour) = 300 mg/hour / 8 mg/mL
Infusion rate (mL/hour) = 37.5 mL/hour

Calculations:
Desired dose: 1.2 million units
Available dose: 600,000 units/2 mL
To find the volume to administer, we can use the following formula:
Volume to administer = (Desired dose / Available dose) * Volume per dose
, Volume to administer = (1,200,000 units / 600,000 units/mL) * 2 mL = 4 mL
Therefore, the nurse should administer 4 mL of the penicillin solution.
D. Decrease cigarette use to a pack per day.
Term 2 of 56
A client with anemia secondary to chronic kidney disease (CKD) started a prescription for
epoetin alfa two months ago. Which client finding best indicates that the medication is
effective?
Reference Range:Hemoglobin (Hgb) [14 to 18 g/dl. (8.7 to 11.2 mmol/L)]
A. Food diary shows increased consumption of iron-rich foods.
B. Reports of increased energy levels and decreased fatigue.
C. Takes concurrent iron therapy without adverse effects.
D. Hemoglobin level increased to 12 g/dL (7.45 mmol/L).
B. Take measures to avoid dehydration and over-heating
D. Hemoglobin level increased to 12 g/dL (7.45 mmol/L).
D. Decrease cigarette use to a pack per day.
D. Double the dose if a dose is missed.
, Term 3 of 56
A male client is admitted for observation because he is reporting progressively increasing
fatigue over the past month and a brief episode of dizziness that occurred today. He has a
history of heartburn and indigestion that he self-treats with ibuprofen and antacids. Which
assessment finding should the nurse report immediately to the healthcare provider?
Reference Ranges:Hemoglobin (14 to 18 g/dL (8.7 to 11.2 mmol/L)]Hematocrit [42% to 52% (0.42
to 0.52 volume fraction)]Gastric pH [1.5 to 3.5]
A. Hematocrit 42% (0.42 volume fraction).
B. Hemoglobin 13 g/dL (8.07 mmol/L).
C. Positive guaiac of stool.
D. Gastric pH 2.0.
C. Positive guaiac of stool
A. Begin therapy 1 week before the next normal menstrual cycle.
B. Take measures to avoid dehydration and over-heating
D. Avoid the use of alcohol.
