A nurse administers 25 mg of a medication to a client from a vial that has 50 mg reconstituted single-dose medication. The client requires two intramuscular injections per day. What is the number of vials required for 5 days?
2 vials
5 vials
10 vials
75 vials
The Correct Answer is B
If one dose of medication is 25 mg and each vial contains 50 mg of medication, then each vial contains two doses..
To calculate the number of vials required for 5 days of treatment, we first need to calculate the total number of doses required. Since the client requires two injections per day, the total number of doses required for 5 days would be:.
Total number of doses = 2 doses/day x 5 days. Total number of doses = 10 doses.
Since each vial contains two doses, we need a total of 10/2 = 5 vials for 5 days of treatment..
Therefore, the nurse would need 5 vials of the medication for 5 days of treatment for the client.

Correct Answer is B
Explanation
To calculate the dose of dobutamine in mg/hr, we need to convert the patient's weight from pounds (lb) to kilograms (kg) and then use the ordered dose of 10 mcg/kg/min.
1 lb = 0.453592 kg (rounded to 6 decimal places) Patient's weight in kg = 110 lb x 0.453592 kg/lb
Patient's weight in kg = 49.89512 kg (rounded to 5 decimal places)
Now we can calculate the dose of dobutamine in mg/hr using the following formula:
Dose (in mg/hr) = Weight (in kg) x Dose (in mcg/kg/min) x 60 (to convert minutes to hours) / 1000 (to convert mcg to mg)
Dose (in mg/hr) = 49.89512 kg x 10 mcg/kg/min x 60 / 1000
Dose (in mg/hr) = 29.937072 mg/hr (rounded to 3 decimal places)
Therefore, the patient should receive a dose of approximately 29.9 mg/hr of dobutamine.
Correct Answer is B
Explanation
We can use proportion to calculate the volume of Primaxin to administer:. 275 mg is to X mL as 500 mg is to 2 mL.
275/X = 500/2.
Cross-multiplying, we get:. 500X = 275 x 2.
X = (275 x 2)/500. X = 1.1 mL.
Therefore, the nurse should administer 1.1 mL of Primaxin to the patient, rounded to the nearest tenth.
