) You are finally well!  But now your child is sick!  You know there have been mistakes in orders so you are on the internet t
rjkz [21]

Answer:

The doctor's dosage was not appropriate.

The right dosage is from 56.625 mg to 113.25 mg of Antibiotic to be given every 6 hour for the child with weight 25 lbs.

Step-by-step explanation:

It is given that 20 to 40 mg/kg/day is the recommended dosage.

Now, the doctor's order is 150 mg of antibiotic to be given every 6 hours. And my child weighs 25 lbs.

Now, 1 lb is equivalent to 0.453 kg.

So, my child's weight is (25 × 0.453) = 11.325 kg.

So, the doctor's order is 150 mg of antibiotic to be given every 6 hours for a child of weight 11.325 kg.

Hence, the dosage is [(150 × 4) ÷ 11.325] = 52.98 mg/kg/day.

So, this is not within the limit of 20 to 40 mg/kg/day.

Therefore, the doctor's dosage was not appropriate.

Now, let the appropriate dosage is x mg per every 6 hours for a child with weight 25 lbs i.e. 11.325 kg.

So, 20 \leq  \frac{4x}{11.325} \leq 40

⇒ 20\leq 0.3532x \leq 40

⇒ 56.625 \leq  x \leq  113.25

So, the right dosage is from 56.625 mg to 113.25 mg of antibiotic to be given every 6 hours for the child with weight 25 lbs. (Answer)

If the domain of f(n) = -4n - 3 is (-1, 1/4,4}, what is the range?
ahrayia [7]

Answer:

Range= \{1,-4,-19\}

Step-by-step explanation:

Given

f(n) = -4n - 3

n = \{-1,1/4,4\} --- domain

Required

Determine the range

To do this, we simply substitute the values of n in the given expression

So, we have:

n = -1

f(-1) = -4 * -1 - 3 =4 - 3 = 1

n = 1/4

f(-1) = -4 * 1/4 - 3 =-1 - 3 = -4

n=4

f(-1) = -4 * 4 - 3 =-16 - 3 = -19

Hence, the range is:

Range= \{1,-4,-19\}
