A nurse is preparing to administer ampicillin 500 mg IM every 6 hr. Available is ampicillin 500 mg vial. The package insert instructs adding 1.8 mL of sterile water to yield ampicillin 250 mg/mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the amount of megestrol oral suspension that the nurse should administer, we can use the following formula:

Amount to administer (mL) = (Desired dose in mg) / (Amount of drug in 1 mL)

Given:

Desired dose = 200 mg

Amount of drug in 1 mL = 40 mg/mL

Now, let's calculate the amount to administer:

Amount to administer (mL) = 200 mg / 40 mg/mL

Amount to administer (mL) = 5 mL

Rounding to the nearest whole number, the nurse should administer 5 mL of the megestrol oral suspension.

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.
