A nurse is preparing to administer amoxicillin 750 mg PO. Available is amoxicillin liquid suspension 250 mg/5 mL. How many mL should the nurse administer?
(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 belimumab that the nurse should administer, we can use the following steps:

Convert the patient's weight from pounds to kilograms.

Multiply the patient's weight in kilograms by the dosage of belimumab (10 mg/kg) to find the total dosage required.

Determine the volume of the drug needed using the concentration of the available belimumab solution.

Given:

Patient's weight = 136 lb

Dosage of belimumab = 10 mg/kg

Available concentration of belimumab = 80 mg/mL

Let's calculate step by step:

Convert patient's weight from pounds to kilograms:

Patient's weight in kg = 136 lb × (1 kg / 2.2 lb) ≈ 61.8 kg

Calculate the total dosage required:

Total dosage = 10 mg/kg × 61.8 kg ≈ 618 mg

Determine the volume of the drug needed using the concentration of the available belimumab solution:

Volume of drug = Total dosage / Concentration of belimumab

Volume of drug = 618 mg / 80 mg/mL ≈ 7.7 mL

Rounding to the nearest whole number, the nurse should administer 8 mL of the belimumab.

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.
