Question

use critical thinking to answer the following.

1. you are to administer 4 tab with a dosage strength of 0.04 mg each. what total dosage are you giving?
2. you have given 2 1/2 (2.5) tab with a strength of 1.25 mg per tablet. what total dosage is this?
3. the tablets your patient is to receive are labeled 0.1 mg, and you are to give 3 1/2 (3.5) tab. what total dosage is this?
4. you gave your patient 3 tab labeled 0.75 mg each, and he was to receive a total of 2.25 mg. did he receive the correct dosage?
5. the tablets available for your patient are labeled 12.5 mg, and you are to give 4 1/2 (4.5) tab. what total dosage will this be?
6. your patient is to receive a dosage of 4.5 mg. the tablets available are labeled 3.5 mg, and there are 2 1/2 tab in his medication drawer. is this a correct dosage?

Explanation:

Step1: Multiply number of tablets by dosage per tablet

For question 11: $4\times0.04 = 0.16$ mg
For question 12: $2.5\times1.25=3.125$ mg
For question 13: $3.5\times0.1 = 0.35$ mg
For question 14: Calculate actual dosage given, $3\times0.75 = 2.25$ mg, and compare with required dosage. Since $2.25$ mg (given) = $2.25$ mg (required), the dosage is correct.
For question 15: $4.5\times12.5=56.25$ mg
For question 16: Calculate actual dosage available, $2.5\times3.5 = 8.75$ mg. Since $8.75$ mg $
eq4.5$ mg, it is not a correct dosage.

Answer:

1. $0.16$ mg
2. $3.125$ mg
3. $0.35$ mg
4. Yes
5. $56.25$ mg
6. No
