A nurse is preparing to administer amoxicillin 2 gm/day PO divided into two doses.
The amount available is amoxicillin 500 mg tablets.
How many tablets should the nurse administer with each dose?
The Correct Answer is ["2"]
Let’s solve the medication math problem step by step:
Step 1: Identify the total daily dose of amoxicillin. The total daily dose is 2 gm/day.
Step 2: Convert the total daily dose from grams to milligrams, as the available medication is in milligrams. We know that 1 gm = 1000 mg, so 2 gm = 2000 mg.
Step 3: The total daily dose is divided into two doses. So, each dose will be 2000 mg ÷ 2 = 1000 mg.
Step 4: Determine the number of tablets for each dose. Each tablet contains 500 mg of amoxicillin. So, the number of tablets for each dose is 1000 mg ÷ 500 mg/tablet = 2 tablets.
So, the nurse should administer 2 tablets of amoxicillin with each dose.

Correct Answer is ["2.5 "]
Explanation
Step 1: Identify the given values. The nurse needs to administer 2.5 mg of hydromorphone. The available amount is 5 mg/5 mL.
Step 2: Set up the calculation. We need to find out how many mL correspond to 2.5 mg. We can set up a proportion using the given values:
5 mL5 mg=x mL2.5 mg
Step 3: Solve for x. Cross-multiply and solve for x:
5 mg×x mL=2.5 mg×5 mL
Step 4: Simplify the equation:
x=5 mg.5 mg×5 mL
Step 5: Calculate the value of x:
x=2.5 mL
So, the nurse should administer 2.5 mL of the hydromorphone elixir.
Correct Answer is ["B","C"]
Explanation
Choice A rationale:
This statement is incorrect. Sulfonamides should be taken for the full time of treatment, even if the patient begins to feel better after a few days. If the medication is stopped too soon, the symptoms may return.
Choice B rationale:
This statement is correct. Sulfonamides can cause increased photosensitivity, which means the skin can be more sensitive to the sun and burn more easily. Therefore, patients should be educated to use sunscreen and protective clothing with sun exposure.
Choice C rationale:
This statement is correct. Sulfonamides are best taken with a full glass (8 ounces) of water. Several additional glasses of water should be taken every day, unless otherwise directed by the doctor. Drinking extra water will help to prevent some unwanted effects of sulfonamides.
Choice D rationale:
This statement is incorrect. Restricting daily fluid intake to 1000ml per day while on sulfonamides could increase the risk of crystalluria that can cause kidney stones or decreased kidney function. Therefore, patients should increase their water intake while taking these medications.
