Question

question 1 of 10. dr. padilla has ordered 250 mg of rocephin by im injection for mr. smith. you have on hand rocephin 1g/4 ml. how many mls should you administer to mr. smith? question 2 of 10. dr. miller has ordered 320 mg of acetaminophen by mouth for ms. penna. available you have 160 mg/5ml. how many ml would you administer? question 3 of 10. dr. kim has ordered for you to administer methylpredisolone 80 mg im now. available is methylpredisolone 40mg/1ml. how many ml should the nurse administer? question 4 of 10. dr. wills ordered eliquis 5mg twice a day by mouth for mr. rybka. eliquis comes in 2.5mg tablets. what is the total number of tablets mr. rybka would take in a day?

Explanation:

Question 1:

Step1: Calculate daily dose of Eliquis

Mr. Rybka takes Eliquis 5 mg twice - a - day, so the daily dose is $5\times2 = 10$ mg.

Step2: Calculate number of tablets

Eliquis comes in 2.5 mg tablets. Let the number of tablets be $n$. Using the formula $n=\frac{\text{total dose}}{\text{dose per tablet}}$, we have $n=\frac{10}{2.5}=4$ tablets.

Question 2:

Step1: Set up proportion for acetaminophen

We know the concentration of acetaminophen is 160 mg/5 mL and the ordered dose is 320 mg. Let the volume to be administered be $V$ mL. Using the proportion $\frac{160}{5}=\frac{320}{V}$.

Step2: Solve for $V$

Cross - multiply: $160V = 320\times5$. Then $V=\frac{320\times5}{160}=10$ mL.

Question 3:

Step1: Set up proportion for Methylprednisolone

The concentration of Methylprednisolone is 40 mg/1 mL and the ordered dose is 80 mg. Let the volume to be administered be $x$ mL. Using the proportion $\frac{40}{1}=\frac{80}{x}$.

Step2: Solve for $x$

Cross - multiply: $40x = 80\times1$. Then $x=\frac{80\times1}{40}=2$ mL.

Answer:

Question 1: 4 tablets
Question 2: 10 mL
Question 3: 2 mL
