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.)
The Correct Answer is ["0.6"]
Step 1: Determine the dosage available per mL.
- Available dosage is 8 mg in 0.4 mL.
- Calculation: 8 mg ÷ 0.4 mL = 20 mg/mL.
- Result: 20 mg/mL.
Step 2: Calculate the volume needed for 12 mg.
- Required dosage is 12 mg.
- Calculation: 12 mg ÷ 20 mg/mL = 0.6 mL.
- Result: 0.6 mL.
So, the nurse should administer 0.6 mL of methylnaltrexone.

Correct Answer is C
Explanation
Option C demonstrates empathy and active listening. By acknowledging the client's emotions and expressing concern, the nurse creates a safe and supportive environment for the client to share their feelings. This response encourages the client to open up and express what they are going through, allowing the nurse to better understand the situation and provide appropriate care and support.
Options A and D are also empathetic but may not prompt the client to share their feelings or concerns as effectively as Option C.
Option B is not appropriate as it minimizes the client's emotions and may discourage them from expressing their feelings further.
