A nurse is preparing to administer ciprofloxacin 250 mg PO every 12 hr. Available is ciprofloxacin 100 mg tablets. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.5"]
Given:
Prescribed dose: 250 mg of ciprofloxacin per dose
Available tablets: 100 mg tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 100 mg tablets are needed to make 250 mg of ciprofloxacin.
Set up a proportion to solve for the unknown number of tablets (X):
100 mg/tablet = 250 mg/X tablets
Cross-multiplying gives us:
100 mg x X tablets = 250 mg x 1 tablet
Simplifying:
100X = 250
Solving for X:
X = 250 / 100 = 2.5 tablets

Correct Answer is A
Explanation
A) Under the tongue: Ergotamine is prescribed for sublingual administration, which means the medication should be placed under the tongue for absorption. Sublingual administration allows the medication to be absorbed directly into the bloodstream through the mucous membranes, bypassing the gastrointestinal system and providing a quicker onset of action.
B) Vaginal: Vaginal administration is not indicated for ergotamine, as this is not a typical route for the medication. Ergotamine is commonly used via sublingual, oral, or rectal routes for migraine treatment, but not vaginally.
C) Topical: Ergotamine is not typically administered topically. The medication is designed for sublingual or oral use, so applying it topically would not provide the intended therapeutic effects for treating a migraine.
D) Subcutaneous: While some medications are administered subcutaneously (under the skin), ergotamine is not commonly given via this route. The prescribed route is sublingual, and administering it subcutaneously would not align with the prescription and could potentially lead to improper absorption and reduced effectiveness.
Correct Answer is ["2722"]
Explanation
Let's convert pounds to grams.
We know that 1 pound= 453.592 grams.
Convert 6 pounds to grams, we multiply:
6 pounds x 453.592 grams/pound = 2721.552 grams
Rounding this to the nearest whole number gives 2722 grams.
