The health-care provider prescribes phytonadione (AquaMEPHYTON) 250 mcg IM to be administered to an infant within 1 hour of admission to the nursery. A 0.5 ml ampule labeled 2 mg in 1 ml is available. The nurse should administer how many ml? (Enter numeric value only. If rounding is required, round to the nearest hundredth.)
The Correct Answer is ["0.13"]
To calculate the volume of phytonadione (AquaMEPHYTON) to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
First, let's convert the desired dose from micro-grams to milligrams:
250 mcg x (1 mg / 1000 mcg) = 0.25 mg
Then, plug in the values into the formula:
Volume (mL) = 0.25 mg / 2 mg/mL
Calculating the result:
Volume (mL) = 0.125 mL
Rounding to the nearest hundredth, the nurse should administer 0.13 mL of phytonadione (AquaMEPHYTON).

Correct Answer is ["6"]
Explanation
To calculate the total number of tablets needed, we'll first calculate the total amount of azithromycin required for the treatment.
Step 1: Calculate the total azithromycin required:
Total Azithromycin = Day 1 Dose + (Day 2-5 Dose x Number of Days)
Total Azithromycin = 500 mg + (250 mg x 4 days)
Total Azithromycin = 500 mg + 1000 mg
Total Azithromycin = 1500 mg
Step 2: Determine the number of tablets needed:
Number of Tablets = Total Azithromycin (mg) / Tablet Strength (mg)
Number of Tablets = 1500 mg / 250 mg/tablet
Number of Tablets = 6
Therefore, the nurse should give the client a total of 6 tablets of azithromycin for the duration of treatment.
Correct Answer is ["3"]
Explanation
First, let's convert grams to milligrams:
0.3 grams x 1000 mg/gram = 300 mg
Then, set up a proportion:
x capsules / 300 mg = 1 capsule / 100 mg
Cross-multiply:
100x = 300
Solve for x:
x = 300 / 100
x = 3
Therefore, the nurse should administer 3 capsules of docusate sodium (Colace).
