A client with impetigo receives a prescription for azithromycin (Zithromax) 500 mg PO on day 1, then 250 mg/day on days 2 through 5 for a total administration of 1.5 gram. The pharmacy has 250 mg tablets available. How many tablets total should the nurse give to the client for the duration of treatment? (Enter numeric value only.)
The Correct Answer is ["6"]
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 ["5.8"]
Explanation
To calculate the infusion rate, we'll follow these steps:
1. Calculate the desired dose rate in mcg/minute:
Desired Dose Rate = Weight (kg) x Dose (mcg/kg/minute)
Desired Dose Rate = 86 kg x 8 mcg/kg/minute
Desired Dose Rate = 688 mcg/minute
2. Convert micro-grams to milligrams:
688 mcg x (1 mg / 1000 mcg) = 0.688 mg/minute
3. Calculate the concentration of dopamine in the IV solution:
Dopamine Concentration = Dopamine (mg) / Solution Volume (mL)
Dopamine Concentration = 800 mg / 500 mL
Dopamine Concentration = 1.6 mg/mL
4. Set up a proportion:
x mL/hour / 0.688 mg/minute = 60 minutes/hour / 1.6 mg/mL
5. Cross-multiply and solve for x:
x mL/hour = 0.688 mg/minute x 60 minutes/hour / 1.6 mg/mL
x mL/hour ≈ 25.8 mL/hour
Therefore, the nurse should program the infusion pump to deliver approximately 25.8 mL/hour.
Correct Answer is ["2"]
Explanation
To determine the number of tablets needed, we can set up a proportion:
x tablets / 0.6 mg = 1 tablet / 0.4 mg
Cross-multiplying:
0.4x = 0.6
Solving for x:
x = 0.6 / 0.4
x = 1.5
Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.
Therefore, the nurse should administer 2 tablets of nitroglycerin 0.4 mg sublingually if the client experiences chest pain
