question 8 of 10.
np helmick has ordered 2 mg of zofran to be given now and then every 8 hours as needed for nausea. the available zofran tablets are 4 mg scored tablets. how many tablets will you administer for the single dose?

Explanation:

Question 7:

Step1: Identify the dosage - needed and tablet - strength

The doctor wants the patient to take 80 mg of Lasix, and the available Lasix tablets are 20 mg each.

Step2: Calculate the number of tablets

Use the formula $n=\frac{D}{S}$, where $D$ is the desired dose (80 mg) and $S$ is the strength of each tablet (20 mg). So $n = \frac{80}{20}=4$ tablets.

Question 8:

Step1: Identify the dosage - needed and tablet - strength

The ordered dose of Zofran is 2 mg, and the available Zofran tablets are 4 mg scored tablets.

Step2: Calculate the number of tablets

Since the tablets are scored and the dose is 2 mg and tablet strength is 4 mg, we use the formula $n=\frac{D}{S}$, where $D = 2$ mg and $S = 4$ mg. So $n=\frac{2}{4}=0.5$ tablets.

Question about Ondansetron:

Step1: Identify the dosage - needed and solution - strength

The ordered dose of Ondansetron is 3 mg, and the available solution is 4 mg/2 mL.

Step2: Set up a proportion

Let $x$ be the volume to be administered. We have the proportion $\frac{4}{2}=\frac{3}{x}$. Cross - multiply to get $4x = 3\times2$, so $4x=6$.

Step3: Solve for $x$

$x=\frac{6}{4}=1.5$ mL.

Answer:

Question 7: 4 tabs
Question 8: 0.5 tabs
Ondansetron: 1.5 mL
