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.
40 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/hr / 60 min/hr = 2 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 D
Explanation
The nurse should instruct the client to cleanse the skin before applying a nitroglycerin transdermal patch 1.
This is because it is important to apply the patch to a clean, dry skin area with little or no hair that is free of scars, cuts, or irritation 1.
Choice A is incorrect because it is not recommended to use an old patch with medication residue.
Instead, always remove a previous patch before applying a new one 1.
Choice B is incorrect because a nitroglycerin patch should not be kept in place for 72 hours before replacing.
Instead, it should be worn for 12 to 14 hours and then removed 2.
Choice C is incorrect because the patch should not be applied to a hairy area of the skin for better adherence.
Instead, it should be applied to an area with little or no hair 1.
Correct Answer is B
Explanation
The nurse should administer 2 tablets of lorazepam 1 mg to give a total dose of 2 mg.
This is calculated by dividing the desired dose (2 mg) by the available dose (1 mg/tablet) to get the number of tablets needed: 2 mg / (1 mg/tablet) = 2 tablets.
Choice A, 1 tablet, is not the correct answer because it would only provide a total dose of 1 mg.
Choice C, 3 tablets, is not the correct answer because it would provide a total dose of 3 mg.
Choice D, 4 tablets, is not the correct answer because it would provide a total dose of 4 mg.
