Answer:

Yes, the doctor's order within the desired range

Step-by-step explanation:

Given:

Dosage of Rocephin ordered = 200 mg

Mass of the infant = 15.4 lb

1 lb = 0.453592 kg

thus,

15.4 lb = 0.453  × 15.4 = 6.97 kg

Dosage is provided every 8 hours

thus,

Number of dosage per day = \frac{\textup{24 hours}}{\textup{8}} = 3

Hence,

the total dosage ordered per day = 200 × 3 = 600 mg

Dosage ordered per kg of infant per day = \frac{\textup{600}}{\textup{6.97}}

or

Dosage ordered per kg of infant per day = 86.083 mg/kg per day

Yes, the doctor's order within the desired range

Multi-step K is the midpoint of JL, JL=4x-2, and JK=7. Find x, KL, and JL
ddd [48]
If K is midpoint of JL then JK = 0.5JL

JL = 4x - 2; JK = 7

The equation:
0.5(4x - 2) = 7
2x - 1 = 7      |add 1 to both sides
2x = 8        |divide both sides by 2
<u>x = 4</u>

<u>JL</u> = 4(4) - 2 = 16 - 2 = <u>14</u>

<u>KL</u> = JK =<u> 7</u>
