Answer and Explanation

The Correct Answer is ["63"]

Given:

Total volume: 250 mL

Time: 4 hours

Steps to solve:

Determine the flow rate:

Set up a proportion to solve for the unknown flow rate (X):

250 mL/4 hr = X mL/1 hr

Cross-multiplying gives us:

250 mL x 1 hr = 4 hr x X mL

Simplifying:

250 = 4X

Solving for X:

X = 250 / 4 = 62.5 mL/hr

Round to the nearest whole number:

63 mL/hr.

Correct Answer is B

Explanation

A) Frequency: The frequency in this prescription is specified as "qhs" (every night at bedtime), which is a standard and appropriate frequency for this type of treatment. There is no issue with the frequency, as it aligns with common treatment regimens for vaginal infections.
B) Route: The prescribed route for clindamycin is vaginal, which is unusual for antibiotics, as they are typically given orally or intravenously. However, clindamycin can be used vaginally for the treatment of infections such as group B streptococcus during pregnancy. The nurse should clarify the route to ensure that this is the intended administration method, especially considering that clindamycin is more commonly prescribed for oral or IV use.
C) Dosage: The dosage of 5 g is appropriate for vaginal clindamycin treatment for group B streptococcus and falls within typical guidelines for this type of therapy. Clindamycin vaginal suppositories or creams are usually dosed in the range of 5 g, making the dosage correct.

D) Medication: Clindamycin is a suitable antibiotic for treating group B streptococcus infections, including when administered vaginally. It is frequently used for such purposes, especially in pregnant women, to prevent neonatal transmission during labor.

Correct Answer is ["100"]

Explanation

Given:

Total volume: 100 mL

Time: 60 minutes

Steps to solve:

Determine the flow rate:

Set up a proportion to solve for the unknown flow rate (X):

100 mL/60 min = X mL/1 min

Cross-multiplying gives us:

100 mL x 1 min = 60 min x X mL

Simplifying:

100 = 60X

Solving for X:

X = 100 / 60 = 1.67 mL/min

Convert to mL/hr:

1.67 mL/min x 60 min/hr = 100 mL/hr
