A client is ordered Mylanta 1 tablespoon by mouth after meals and at bedtime. How many milliliters should the client take with each dose?
5 mL
10 mL
15 mL
30 mL
The Correct Answer is C
A. 5ML: One tablespoon is equivalent to 15 milliliters, so 5 milliliters is too little for the prescribed dose.
B. 10ML: This amount is also insufficient, as it does not match the standard conversion of one tablespoon to milliliters.
C. 15ML: This is the correct conversion, as one tablespoon is equal to 15 milliliters.
D. 30ML: This amount is double the correct dose, which could lead to overmedication and potential side effects.

Correct Answer is A
Explanation
To calculate the dose of brentuximab in mg that the client should receive, we need to multiply the weight of the client in kg by the prescribed dose of 1.8 mg/kg:.
Dose (in mg) = Weight (in kg) x Dose (in mg/kg).
Dose (in mg) = 60 kg x 1.8 mg/kg. Dose (in mg) = 108 mg.
Now we need to calculate the volume of medication to administer. Since the medication available is 50 mg per 10 mL, we can use proportion to calculate the volume:.
50 mg is to 10 mL as 108 mg is to X mL. 50/10 = 108/X.
Cross-multiplying, we get:. 50X = 108 x 10.
X = (108 x 10)/50. X = 21.6 mL.
Therefore, the nurse should administer 21.6 mL of brentuximab to the client.
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%.
