A nurse is preparing to administer levothyroxine 0.75 mg PO once a day. The amount available is levothyroxine 88 mcg/tablet. How many tablets 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.)
The Correct Answer is ["9"]
Step 1: Convert the dosage from mg to mcg. 0.75 mg × 1000 = 750 mcg Result: 750 mcg
Step 2: Determine the number of tablets needed. 750 mcg ÷ 88 mcg/tablet = 8.5227 tablets Result: 8.5227 tablets
Step 3: Round the result to the nearest whole number. 8.5227 tablets rounded to the nearest whole number = 9 tablets Result: 9 tablets
The nurse should administer 9 tablets per dose.

Correct Answer is C
Explanation
A: A simple face mask provides a moderate concentration of oxygen but does not have a one-way valve to deliver the highest concentration of oxygen.
B: A Venturi mask delivers a precise concentration of oxygen but is not designed to provide the highest concentration of oxygen with a one-way valve.
C: A non-rebreather mask is the correct choice. It has a one-way valve that prevents exhaled air from re-entering the bag, allowing the delivery of the highest concentration of oxygen to the client.
D: A partial rebreather mask provides a high concentration of oxygen but does not have a one-way valve, making it less effective than a non-rebreather mask for delivering the highest oxygen concentration.
