A nurse has to administer 10 mcg/kg of digoxin to a client who weighs 30 lb. The nurse has available digoxin 1 mg/mL. How many mL would the nurse administer to the child?
0.14 mL
0.136 mL
136 mL
300 mL
The Correct Answer is B
To calculate the dose of digoxin in micrograms (mcg) that the child should receive, we need to first convert the weight of the child from pounds to kilograms:.
30 lb / 2.205 = 13.61 kg.
Next, we can calculate the dose of digoxin in mcg:. Dose (in mcg) = Weight (in kg) x Dose (in mcg/kg). Dose (in mcg) = 13.61 kg x 10 mcg/kg.
Dose (in mcg) = 136.1 mcg.
Now we need to calculate the volume of digoxin solution to administer. Since the concentration of the digoxin solution is 1 mg/mL, we can use proportion to calculate the volume:.
1 mg is to 1 mL as 136.1 mcg is to X mL. 1/1 = 136.1/X.
Cross-multiplying, we get:. 1X = 136.1 x 1.
X = 136.1 mL.
Therefore, the nurse should administer 0.1361 mL (136.1 mcg) of digoxin to the child.

Correct Answer is A
Explanation
Dextrose 50%, add 1 mL to 4 mL injectable saline. To obtain 5 mL of 10% dextrose, 0.5 mL of the 50% dextrose should be diluted with 4.5 mL of sterile water or normal saline. Therefore, the nurse should add 1 mL of the 50% dextrose to 4 mL of injectable saline to get a final concentration of 10% dextrose in 5 mL. This will give the client the appropriate dose.
Choice B is incorrect because adding 2 mL of the 50% dextrose to 3 mL of saline would give a final concentration of 20%, which is higher than the prescribed concentration of 10%.
Choice C is incorrect because adding 3 mL of the 50% dextrose to 2 mL of saline would give a final concentration of 30%, which is significantly higher than the prescribed concentration of 10%.
Choice D is incorrect because adding 4 mL of the 50% dextrose to 1 mL of saline would give a final concentration of 40%, which is much higher than the prescribed concentration of 10%.
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.
