A client is ordered ampicillin 0.5 g po every 6 hours. On hand are ampicillin capsules labeled 250mg. How many capsules will the nurse administer for single dose?

A) At the umbilicus:
After delivery, the fundus is typically located at or just below the umbilicus in the immediate postpartum period, but it will gradually descend over the next few days. By 8 hours postpartum, the fundus is often slightly below the umbilicus, not directly at the umbilicus. The fundus will continue to shrink in size and move downward toward the pelvic region as the uterus contracts and involutes.

B) At a non-palpable depth:
A fundus that is non-palpable is generally expected later in the postpartum period, typically by 10-14 days after delivery, as the uterus contracts and returns to its pre-pregnancy size. At 8 hours postpartum, the fundus is still palpable, generally just below the umbilicus, and should be evaluated for firmness and position.

C) Just above the symphysis pubis:
The fundus is usually higher than the symphysis pubis at 8 hours postpartum, as it is still in the process of descending from the higher position it occupied during pregnancy. It would be expected to be just below the umbilicus or about 1 to 2 finger widths below it. By the second or third day postpartum, the fundus begins to move lower toward the symphysis pubis as it continues to involute.

D) Just below the umbilicus:
Eight hours after delivery, the nurse should expect to palpate the fundus just below the umbilicus. This is a typical finding as the uterus begins to contract and shrink after the delivery of the placenta. The fundus will descend about 1-2 cm per day postpartum, so by 8 hours, it is usually just slightly below the level of the umbilicus.

Given:

Desired dose: Ampicillin 0.5 g PO

Available concentration: Ampicillin capsules 250 mg each

To find:

Number of capsules to administer for a single dose

Step 1: Convert desired dose to milligrams

We know that 1 gram (g) is equal to 1000 milligrams (mg). Therefore, to convert the desired dose from grams to milligrams, we multiply by 1000:

Desired dose (mg) = Desired dose (g) x 1000

Desired dose (mg) = 0.5 g x 1000 = 500 mg

Step 2: Calculate the number of capsules

To find the number of capsules, we divide the desired dose by the strength of each capsule:

Number of capsules = Desired dose / Capsule strength

Number of capsules = 500 mg / 250 mg/capsule = 2 capsules
