Question 1 of 5
A nurse is preparing to administer methylnaltrexone 12 mg subcutaneously to a client who has opioid-induced constipation. Available is methylnaltrexone 8 mg/0.4 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.6
Rationale:
Correct
Answer: 0.6 mL
Rationale:
1. Calculate the total dose needed: 12 mg
2. Determine the concentration: 8 mg/0.4 mL
3. Use the formula: dose required/concentration on hand = volume to administer
4. Substitute values: 12 mg/8 mg = x/0.4 mL
5. Solve for x: x = (12 mg * 0.4 mL) / 8 mg = 0.6 mL
Summary:
-
Choice A: Incorrect, as it does not align with the correct calculation.
-
Choices B to G: Irrelevant, as they do not provide any valid reasoning or calculations.
