A nurse is preparing to administer 400 mL of 0.9% sodium chloride IV over 8 hours.

The drop factor of the manual IV tubing is 60 gtt/mL.

The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number.

Use a leading zero if it applies. Do not use a trailing zero.).

Answer and Explanation

The Correct Answer is ["50"]

To calculate the flow rate in gtt/min, you need to divide the total volume of the IV fluid (400 mL) by the total infusion time in minutes (8 hours x 60 minutes/hour = 480 minutes) and then multiply by the drop factor of the manual IV tubing (60 gtt/mL).

This gives you a flow rate of (400 mL / 480 minutes) x 60 gtt/mL = 50 gtt/min.

The other choices are not answers because they are not provided in the question.

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.

A. Remove the used patch with medication areas to the inside and discard it in a closed receptacle. B. Keep the current nitroglycerin patch in place for 24 hours per day. C. Cleanse the excess hair from the skin before applying a nitroglycerin patch. D. Apply a second patch in place if angina pain occurs.

Correct Answer is A

Explanation

The client should remove the used patch with medication areas to the inside and discard it in a closed receptacle 1.
Choice B is incorrect because the nitroglycerin patch should not be kept in place for 24 hours per day.
Instead, it should be worn for 12 to 14 hours and then removed 12.
Choice C is incorrect because while 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, there is no specific instruction to cleanse excess hair from the skin before applying the patch.
Choice D is incorrect because a second patch should not be applied if angina pain occurs.
Nitroglycerin transdermal patches are used to reduce the number of angina attacks over a long time and will not relieve an attack that has already started because it works too slowly 1.
Instead, the client should check with their doctor if they also need a fast-acting medicine to relieve the pain of an angina attack 1.
