A nurse is calculating the dose of medication for a client. The prescribed dose is 2.5 mg/kg. The client weighs 70 kg. What dosage of medication should the nurse prepare?
700 mg
175 mg
250 mg
35 mg
The Correct Answer is B
A. 700 mg results from an incorrect calculation, perhaps by misapplying the weight or dose.
B. The dosage calculation is performed by multiplying the prescribed dose (2.5 mg/kg) by the client's weight (70 kg): 2.5 mg/kg x 70 kg = 175mg.
C. 250 mg does not align with the given weight or prescribed dose.
D. 35 mg is significantly lower than the calculated dosage.

C. Selective toxicity refers to the ability of an anti-infective to kill or inhibit the growth of microorganisms without causing harm to the host. This principle is fundamental in developing effective antimicrobial agents that target pathogens while minimizing toxicity to human cells.
