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

Answer and Explanation

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 C

Explanation

The Tylenol 3 medication contains codeine 30 mg and acetaminophen (APAP) 300 mg per tablet.

The physician has ordered Tylenol 3 30 mg every 4-6 hours as needed for pain. Therefore, the nurse should administer 1 tablet (containing 30 mg of codeine and 300 mg of APAP) every 4-6 hours as needed for pain..

It is important to note that the maximum daily dose of acetaminophen is 4,000 mg. Therefore, the nurse should monitor the total daily dose of acetaminophen the patient receives from all sources to ensure it does not exceed 4,000 mg.

A. The nurse should give one tablet of medication daily. B. The nurse should give two tablets of medication thrice daily. C. The nurse should give half a tablet of medication to the client daily. D. The nurse should give four tablets of medication to the client every eight hours.

Correct Answer is B

Explanation

The nurse should give two tablets of medication thrice daily. To find the number of tablets to administer, use the formula: (dose / tablet strength). In this case, (15 g/day / 0.5 g/tablet) = 30 tablets/day.

Divide by three to get the number of tablets per dose: 30 / 3 = 10 tablets/dose.

Each tablet has a score mark, which means it can be split in half.

Therefore, the nurse should give two tablets (or four halves) of medication thrice daily. Niacinamide is a form of vitamin B3 that is essential for many cellular functions and energy production. Niacinamide can be used to treat niacin deficiency, which can cause pellagra, a condition characterized by skin lesions, diarrhea, and mental confusion.

Niacinamide may also have anti-inflammatory and antioxidant effects and may benefit skin health and neurological function..
