A nurse needs to administer medication to a patient who weighs 170 pounds. If the dosage is 2 milligrams per kilogram, how much medication should the nurse administer in milligrams? (Round your answer to the nearest whole number.) Hint: 1 pound = 0.454 kilograms

Rationale

The nurse should administer 154 milligrams of medication.

To determine the correct dosage, the patient's weight in pounds must be converted to kilograms. The weight of 170 pounds is approximately 77.11 kilograms (170 pounds × 0.454 kg/pound). Multiplying this weight by the dosage of 2 mg/kg results in about 154.22 milligrams, which rounds to 154 milligrams.

A (77 milligrams) YOUR ANSWER

This choice is incorrect because it does not reflect the correct conversion of the patient's weight from pounds to kilograms or the proper calculation of the dosage. The dosage calculation must be based on the patient's total weight in kilograms, which is significantly higher.

B (374 milligrams) YOUR ANSWER

This option is incorrect as it results from an incorrect assumption about the patient's weight or a miscalculation of the dosage. The correct conversion and multiplication do not yield this amount, indicating a fundamental miscalculation in determining the required dosage.

C (154 milligrams) CORRECT

This is the correct choice. The calculation starts with converting 170 pounds to approximately 77.11 kilograms. Multiplying this by 2 mg/kg gives the proper dosage of about 154 milligrams after rounding.

D (187 milligrams) YOUR ANSWER

This choice is incorrect as it suggests a higher dosage than necessary. It likely stems from a miscalculation in converting the weight or in calculating the required dosage based on the conversion to kilograms.

Conclusion

The correct administration of medication relies on accurately converting weight from pounds to kilograms and applying the prescribed dosage. In this scenario, the proper calculations confirm that the nurse should administer 154 milligrams based on the patient's weight of 170 pounds. Other options did not adhere to the proper conversion or dosage calculation, underscoring the importance of accuracy in medical dosing.
