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?
The Correct Answer is ["2"]
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

Correct Answer is ["33"]
Explanation
Given:
Total volume to infuse: 100 mL
Infusion time: 60 minutes
Drop factor of tubing: 20 gtt/mL
To find:
Drip rate (gtt/min)
Step 1: Calculate the total number of drops
Total drops = Total volume x Drop factor
Total drops = 100 mL x 20 gtt/mL = 2000 gtt
Step 2: Calculate the drip rate
Drip rate = Total drops / Infusion time in minutes
Drip rate = 2000 gtt / 60 minutes = 33.33 gtt/min
Step 3: Round to the nearest whole number
33 gtt/min.
Correct Answer is ["C","E","H","I"]
Explanation
Findings that require follow-up:
Uterus boggy at 24 hr postpartum:
A boggy uterus indicates poor uterine contraction, which can lead to postpartum hemorrhage. Effective uterine contraction is crucial to prevent excessive bleeding after delivery, and this finding warrants immediate intervention, such as fundal massage or administering uterotonic medications.
Lochia rubra with foul odor:
Foul-smelling lochia is a sign of potential infection, often indicative of endometritis, which is an infection of the uterine lining. The presence of this odor requires prompt follow-up and possibly antibiotic treatment to prevent further complications.
Elevated temperature (38.3°C/100.9°F) at 24 hr postpartum:
A postpartum fever may indicate infection, such as endometritis or a urinary tract infection (UTI). This fever should be investigated further to determine the cause and appropriate treatment, as untreated infections can lead to serious complications.
Increased heart rate (105/min) at 24 hr postpartum:
Tachycardia in the postpartum period can be a sign of infection or early signs of hemodynamic instability, possibly due to blood loss or infection. Close monitoring is necessary, and the healthcare provider should be notified to evaluate the cause and initiate treatment if necessary.
