A nurse is preparing to administer levothyroxine 50 micrograms to a client. Available is levothyroxine 0.025 mg/tablet. How many tablets should the nurse administer per dose?
The correct answer and Explanation is :
To determine how many tablets of levothyroxine should be administered to the client, we need to convert the units of the medication from micrograms to milligrams and then calculate the appropriate number of tablets.
Step-by-Step Solution:
- Convert the Dose from Micrograms to Milligrams:
- Levothyroxine dose required: 50 micrograms (mcg)
- Since 1 milligram (mg) is equal to 1000 micrograms, you can convert 50 mcg to mg as follows:
[
\text{50 mcg} \div 1000 = 0.05 \text{ mg}
]
- Determine the Amount of Medication per Tablet:
- The available levothyroxine is in 0.025 mg tablets.
- Calculate the Number of Tablets Needed:
- To find out how many tablets are needed, divide the required dose in mg by the amount of mg per tablet:
[
\text{Number of tablets} = \frac{0.05 \text{ mg}}{0.025 \text{ mg/tablet}}
] - Performing the division:
[
\text{Number of tablets} = 2
]
Explanation:
Levothyroxine is a medication used to treat hypothyroidism by supplementing the thyroid hormone. The dosage of levothyroxine must be accurate to effectively manage thyroid hormone levels and avoid side effects.
In this scenario, the prescribed dose is 50 mcg, which converts to 0.05 mg. The tablets provided are each 0.025 mg. By dividing the required dose (0.05 mg) by the amount per tablet (0.025 mg), we determine that 2 tablets are necessary to meet the dose.
Correct dosage calculations are crucial in nursing practice to ensure that patients receive the appropriate amount of medication. Administering the correct dose helps in achieving therapeutic goals and minimizing the risk of adverse effects associated with under or overdosing.
