A nurse is obtaining a medication history from a client who reports taking 1 oz of magnesium hydroxide daily as a laxative. The nurse should identify that this dose equates to how many mL?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: Using a soft bristled tooth brush can prevent gum bleeding and irritation that may occur with a hard bristled tooth brush. Gum bleeding can be a sign of excessive anticoagulation and increased risk of bleeding.

Choice B reason: Reporting black or bloody bowel movements is important because it can indicate gastrointestinal bleeding, which can be a serious complication of warfarin therapy. Gastrointestinal bleeding can cause anemia, shock, and even death if not treated promptly.

Choice C reason: Limiting all fruits and vegetables is not necessary for a client taking warfarin. However, some fruits and vegetables, especially those that are high in vitamin K, can interfere with the effect of warfarin and increase the risk of clotting. Vitamin K is found in green leafy vegetables, such as spinach, kale, broccoli, and cabbage, and some fruits, such as avocado, kiwi, and grapes. The client should maintain a consistent intake of vitamin K and avoid sudden changes in their diet.

Choice D reason: Reporting coffee ground or bloody emesis is also important because it can indicate upper gastrointestinal bleeding, which can be another serious complication of warfarin therapy. Upper gastrointestinal bleeding can cause hematemesis, melena, anemia, and hypovolemic shock.

Choice E reason: Shaving with an electric razor instead of a razor blade can prevent skin cuts and bleeding that may occur with a razor blade. Skin cuts and bleeding can be a sign of excessive anticoagulation and increased risk of bleeding.

To calculate the amount of voriconazole to be administered, we can follow these steps:

Convert the client's weight from pounds to kilograms.

Calculate the total amount of voriconazole needed based on the client's weight.

Determine the volume of the medication to be administered based on the concentration of the available solution.

Let's proceed with the calculations:

Converting the client's weight from pounds to kilograms:

Client's weight = 127 lb

1 lb ≈ 0.453592 kg

Client's weight ≈ 127 lb 0.453592 kg/lb ≈ 57.61 kg

Calculating the total amount of voriconazole needed:

Voriconazole dose = 6 mg/kg 57.61 kg ≈ 345.66 mg

Determining the volume of the medication to be administered:

Available voriconazole concentration = 5 mg/mL

Volume to be administered = 345.66 mg / 5 mg/mL ≈ 69.132 mL

Rounding to the nearest whole number, the nurse should administer 69 mL of voriconazole.
