A physician orders Dobutamine 10 mcg/kg/min for a patient. The patient is 110 lb.
How many milligrams per hour should the patient receive?
0.5 mg/hr
30 mg/hr
60 mg/hr
145 mg/hr
The Correct Answer is B
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
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 D
Explanation
According to the web, the abdomen is the preferred site for insulin injection because insulin is absorbed more quickly and predictably there.
This helps to maintain a stable blood glucose level and avoid hypoglycemia or hyperglycemia.
The other choices are not answers because:
Choice A (it is the least painful location for this injection) is incorrect because pain depends on various factors, such as needle size, injection technique, and individual sensitivity. The abdomen may not be the least painful location for everyone.
Choice B (it causes less bruising at the site) is incorrect because bruising can occur at any injection site if the needle damages a blood vessel. The abdomen does not have less blood vessels than other sites.
Choice C (there are fewer insulin side effects when given in this site) is incorrect because insulin side effects are not related to the injection site, but to the dose, type, and quality of insulin. The abdomen does not reduce the risk of side effects such as allergic reactions, weight gain, or low blood sugar.
