A nurse is preparing to administer dextrose 3.5% in water (D3.5W) 1200 mL to infuse over 24 hours.
The drop factor of the manual IV infusion is 15 gtt/mL.
How many gtt/min should the nurse set the infusion to deliver? (Round to the nearest whole number.
Use a leading zero if it applies. Do not use a trailing zero.).
25 gtt/min.
13 gtt/min.
42 gtt/min.
15 gtt/min.
The Correct Answer is B
Step 1: Calculate the total infusion time in minutes.
24 hours × (60 minutes/hour) = 1440 minutes.
Step 2: Calculate the infusion rate in mL/min.
1200 mL ÷ 1440 minutes = 0.833 mL/min.
Step 3: Calculate the drop rate in gtt/min.
0.833 mL/min × 15 gtt/mL = 12.495 gtt/min.
Step 4: Round to the nearest whole number.
12.495 ≈ 13 gtt/min.
Answer: 13 gtt/min.

Correct Answer is C
Explanation
This is the first step in controlling bleeding and preventing hematoma formation 1.
Applying direct pressure to the wound with a sterile gauze or a clean cloth can help stop the bleeding 2.
Choice A is not the best answer because a tourniquet should only be used as a last resort to control life-threatening bleeding from a limb 2.
Choice B is not the best answer because placing the client in a modified Trendelenburg position is not necessary for this situation.
Choice D is not the best answer because settling the client in a reclining position is not necessary for this situation.
Correct Answer is B
Explanation
To calculate the volume of cefixime oral suspension that the nurse should administer, you need to divide the prescribed dose (200 mg) by the concentration of the suspension (100 mg/mL).
This gives you 200 mg ÷ 100 mg/mL = 2 mL.
Therefore, the nurse should administer 2 mL of cefixime oral suspension.
Choice A is incorrect because 1.9 mL would provide a dose of 190 mg.
Choice C is incorrect because 2.1 mL would provide a dose of 210 mg.
Choice D is incorrect because 2.2 mL would provide a dose of 220 mg.
