Order: Ampicillin (Principen) 150 mg PO every 6 hours
Available: Ampicillin (Principen) 125mg per 5 ml
How many mL of ampicillin are needed for one dose?
( Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero. TYPE THE ANSWER ONLY, no label )
The Correct Answer is ["6"]
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

Correct Answer is A
Explanation
A. Adequacy of circulation:
This assessment is the highest priority for a client who has undergone a procedure to bypass arteries in the right leg. Monitoring for signs of adequate blood flow, such as color, temperature, capillary refill, and pulses in the operated leg, is critical to identify and address any circulation issues early.
B. Patency of airway:
While maintaining a patent airway is always a priority in postoperative care, it is not the immediate concern in a client who has just undergone a leg bypass procedure. Airway management is essential, but assessing circulation in the operated limb takes precedence.
C. Movement of lower leg:
Assessing movement of the lower leg is important for detecting signs of impaired motor function or complications. However, it is secondary to assessing the adequacy of circulation, which is critical for preventing ischemia and other circulatory issues.
D. Neurovascular status of the left leg:
While monitoring the neurovascular status of the left leg is a valid aspect of the overall assessment, the priority in the immediate postoperative period is to assess the surgical site (right leg) to ensure that blood flow is adequate and that there are no immediate complications.
Correct Answer is ["20"]
Explanation
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.
