A nurse is preparing to administer Lactated Ringer's solution IV to infuse at 120 mL/hr for a client who has a respiratory disorder. The drop factor in the manual IV tubing is 60 gtt/mL. The nurse should set the flow rate to deliver how many gtts/min?
20 gtt/min.
30 gtt/min.
120 gtt/min.
50 gtt/min.
The Correct Answer is C
The nurse should set the flow rate to deliver 40 gtts/min.
This can be calculated by multiplying the infusion rate (120 mL/hr) by the drop factor (60 gtt/mL) and then dividing by the number of minutes in an hour (60 min/hr): (120 mL/hr) * (60 gtt/mL) / (60 min/hr) = 120 gtt/min
Choice A is not the best answer because setting the flow rate to deliver 20 gtts/min would not provide the desired infusion rate of 120 mL/hr.
Choice B is not the best answer because setting the flow rate to deliver 30 gtts/min would not provide the desired infusion rate of 120 mL/hr.
Choice D is not the best answer because setting the flow rate to deliver 50 gtts/min would provide a higher infusion rate than desired.

Correct Answer is A
Explanation
The nurse should include in the teaching that the client should use a soft-bristled toothbrush.
Heparin is an anticoagulant that decreases the clotting ability of the blood 1.
Using a soft-bristled toothbrush can help prevent bleeding of the gums while brushing teeth.
Choice B is incorrect because heparin should not be injected deep into the thigh muscle.
Instead, it should be given subcutaneously (under the skin) 2.
Choice C is incorrect because black and tarry stools are not an expected side effect of heparin.
Choice D is incorrect because easy bruising does not indicate that the medication is effective.
Instead, easy bruising may be a side effect of heparin and should be reported to the healthcare provider 1.
