A nurse is preparing to administer 0.45% sodium chloride 000 mL IV to infuse over 6 hr to a postpartum client. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["167"]
Given:
Total volume: 1000 mL
Time: 6 hours
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
1000 mL/6 hr = X mL/1 hr
Cross-multiplying gives us:
1000 mL x 1 hr = 6 hr x X mL
Simplifying:
1000 = 6X
Solving for X:
X = 1000 / 6 = 166.67 mL/hr
Round to the nearest whole number:
167 mL/hr.

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 ["0.65"]
Explanation
Given:
Prescribed dose: 104 mg of medroxyprogesterone
Available concentration: 104 mg/0.65 mL
Steps to solve:
Concentration is 104 mg/0.65 mL
To administer 104 mg of medroxyprogesterone, the nurse needs to administer exactly 0.65 mL.
