The healthcare provider prescribes 0.075 mg of levothyroxine by mouth (PO) daily. The medication is labeled, "50 mcg tablets." How many tablets should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.5"]
To calculate the number of tablets, we need to use the formula:
Number of tablets = Dose (mg) / Strength (mg/tablet)
First, we need to convert the dose and the strength from micrograms (mcg) to milligrams (mg) by dividing by 1,000. In this case, 0.075 mg is equivalent to 75 mcg and 50 mcg is equivalent to 0.05 mg.
Plugging in the given values, we get:
Number of tablets = 75 mcg / 50 mcg
Simplifying, we get:
Number of tablets = 1.5
Rounding to the nearest tenth, we get:
Number of tablets = 1.5

Correct Answer is ["3.8"]
Explanation
To calculate the volume of oseltamivir suspension, we need to use the formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Since the client weighs 35 pounds, which is between 34 and 50.6 pounds, the recommended dose is 45 mg BID for 5 days. Plugging in this value and the concentration of oseltamivir suspension, we get:
Volume (mL) = 45 mg / 12 mg/mL
Simplifying, we get:
Volume (mL) = 3.75 mL
Rounding to the nearest tenth, we get:
Volume (mL) = 3.8 mL
Correct Answer is ["0.75"]
Explanation
To calculate the volume of interferon beta-1b solution, we need to use the formula:
Volume (mL) = Dose (mg) x Dilution factor (mL/mg)
The dilution factor is the ratio of the volume of sterile water to the amount of powder in the vial. In this case, it is 1.2 mL / 0.3 mg.
Plugging in the given values, we get:
Volume (mL) = 0.1875 mg x 1.2 mL / 0.3 mg
Simplifying, we get:
Volume (mL) = 0.75 mL
