To begin talking with a newly admitted patient about pain management, the nurse would most appropriately state:

To calculate the amount of medication the nurse should give, you can use the formula:

Amount to Give (in ml) = Dose Required (in mg) / Concentration (in mg/ml)

In this case:

Dose Required = 400 mg

Concentration = 300 mg/ml

Now, plug these values into the formula:

Amount to Give (in ml) = 400 mg / 300 mg/ml ≈ 1.33 ml

The nurse should give approximately 1.33 ml of the medication.

A. Changing the subject:
Changing the subject refers to diverting the conversation away from the topic the patient wants to discuss. This can be seen as a blocking technique if used to avoid uncomfortable or challenging discussions. It's essential to stay focused on the patient's concerns to ensure effective communication.

B. Offering false reassurance:
Offering false reassurance occurs when a healthcare provider tries to comfort a patient by stating that everything will be fine, even if they cannot guarantee the outcome. While well-intentioned, this can hinder communication because it may discourage the patient from sharing their genuine concerns, fearing they won't be taken seriously.

C. Inattentive listening:
Inattentive listening happens when a healthcare provider is physically present but not mentally engaged in the conversation. This can occur due to distractions or preoccupation with other thoughts. It hampers effective communication because the patient may feel neglected or unheard, leading to dissatisfaction and misunderstandings.

D. Giving information:
Providing information is a fundamental aspect of healthcare communication. However, if done without actively listening to the patient's concerns or without considering their emotional state, it might not address the underlying issues. Effective communication involves both giving information and actively listening to the patient's thoughts, feelings, and questions.
