74. How many 10 mg tablets need to be dispensed?
Answer: D
42 tablets need to be dispensed.
To fulfill the required dosage, a total of 42 tablets of 10 mg each must be dispensed.
A) 6
Dispensing 6 tablets would only provide a total of 60 mg, which is significantly less than necessary. This option does not meet the dosage requirement and is therefore incorrect.
B) 12
Dispensing 12 tablets would yield a total of 120 mg. While this amount is higher than the 60 mg needed, it still does not satisfy the requirement of providing sufficient dosage, making this option incorrect.
C) 24
Dispensing 24 tablets results in a total of 240 mg, which far exceeds the required dosage. This option is not appropriate as it supplies too much medication, thus it is incorrect.
D) 42
Dispensing 42 tablets of 10 mg each provides a total of 420 mg, which meets and exceeds the required daily dosage of 60 mg. This option correctly addresses the question's requirement and is therefore the correct choice.
Conclusion
The correct answer is 42 tablets, as it meets the necessary dosage requirements effectively. All other options fail to provide the correct amount, either under-dosing or over-dosing the patient. Hence, option D is the only viable choice based on the context of the question.
