A prescription reads: Triamcinolone 0.1% cream Apply to trunk b.i.d. p.r.n. Disp. 1 lb How much cream should the patient receive?

Rationale

454 g of Triamcinolone cream should be dispensed to the patient.

The prescription indicates that 1 lb of cream should be dispensed. Since 1 pound is equivalent to approximately 454 grams, this is the correct amount of cream to provide.

A (240 mg) YOUR ANSWER

240 mg is a much smaller quantity than what is prescribed. This amount translates to only 0.24 grams, which is insufficient for the treatment intended by the prescription. The patient requires significantly more cream to meet the dosage specified.

B (30 oz) YOUR ANSWER

30 ounces is equivalent to approximately 850 grams, which exceeds the prescribed amount of 1 lb. This option is incorrect because it does not align with the specific quantity indicated in the prescription, which is 454 grams.

C (454 g) CORRECT

This choice correctly represents the conversion of 1 lb into grams, as there are 454 grams in a pound. Therefore, this option accurately reflects the amount of Triamcinolone cream that should be dispensed based on the prescription.

D (2200 mL) YOUR ANSWER

2200 mL is equivalent to 2.2 liters, which is far more than the volume contained in 1 lb of cream. Since the cream's density is approximately 1 g/mL, this would suggest a weight of 2200 grams, indicating a substantial overestimation in the amount prescribed.

Conclusion

The prescription specifies the dispensing of Triamcinolone cream as 1 lb, which converts to 454 grams. This amount is critical for ensuring the patient receives the correct dosage for their treatment. Other options misrepresent the required quantity, either underestimating or overestimating the amount needed, thus making 454 g the only accurate choice.
