Ordered: furosemide (Lasix) 20mg

Available: furosemide (Lasix) 2 mg/2 mL

Administer: ____mL
Answer and Explanation

The Correct Answer is ["20"]

To administer the ordered dose of furosemide (Lasix) 20mg, you need to calculate the amount of mL required from the available solution. The available solution has a concentration of 2 mg/2 mL, which means that for every 2 mL of solution, there are 2 mg of furosemide. To find the amount of mL needed to deliver 20 mg of furosemide, you can use the following formula:

mL = (ordered dose / available dose) x available volume

Plugging in the values, we get:

mL = (20 mg / 2 mg) x 2 mL

mL = 10 x 2 mL

mL = 20 mL

Therefore, you need to administer 20 mL of the available solution to give the patient 20 mg of furosemide.

Correct Answer is B

Explanation

A. Place the client on bed rest in supine position:

While bed rest might be appropriate for certain respiratory conditions, it is not a specific intervention for crackles. In fact, changing the client's position, such as having them sit up, may enhance lung function and help with breathing.

B. Repeat auscultation after asking the client to breathe deeply and cough:

This is the correct action. Repeating auscultation after having the client take deep breaths and cough can provide additional information about the nature of the crackles and may help clear the airways temporarily.

C. Prepare to administer antibiotics:

Administering antibiotics would be considered if the crackles are indicative of a respiratory infection. However, determining the need for antibiotics would require a more comprehensive assessment, including diagnostic tests.

D. Instruct the client to limit fluid intake to less than 2,000 mL/day:

Limiting fluid intake is not a direct intervention for crackles. This action is typically considered in conditions like heart failure where there is a risk of fluid overload. It is not the primary intervention for addressing crackles in the lungs.

Correct Answer is ["6"]

Explanation

To calculate the amount of ampicillin needed for one dose, we need to use a proportion. We can set up the proportion as follows:

150 mg / x mL = 125 mg / 5 mL

We can cross-multiply and solve for x:

150 * 5 = 125 * x

750 = 125 * x

x = 750 / 125

x = 6

Therefore, we need 6 mL of ampicillin for one dose
