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.).
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.
Correct Answer is A
Explanation
The nurse should instruct the patient to avoid taking verapamil with grapefruit.
Studies have demonstrated an interaction between verapamil and grapefruit juice, which is likely due to an inhibition of intestinal metabolism resulting in increased oral bioavailability1.
This means that grapefruit can interfere with the enzymes that break down verapamil in your digestive system, potentially leading to dangerous health problems2.
Choices B, C, and D are incorrect because there is no known interaction between verapamil and spinach, broccoli, or carrots.
