A nurse in the emergency department is preparing to administer naloxone 0.4 mg IV bolus to a client who has opioid-induced respiratory depression. Available is naloxone injection 0.2 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2"]

To calculate the amount of naloxone to administer, you can use the following formula:

Amount to administer (mL) = Total dose required (mg) / Concentration of drug (mg/mL)

Given:

Total dose required = 0.4 mg

Concentration of drug = 0.2 mg/mL

Let's calculate the amount to administer:

Amount to administer (mL) = 0.4 mg / 0.2 mg/mL

Now, perform the calculation:

Amount to administer (mL) = 2 mL

So, the nurse should administer 2 mL of naloxone intravenously as a bolus dose to the client.

Correct Answer is C

Explanation

When dealing with a client who is manipulative and disruptive but not demonstrating behaviors that are a threat to self or others, it is essential for the nurse to set clear and consistent boundaries for behavior. This helps establish a therapeutic environment and maintains the safety and well-being of both the client and others in the milieu.

Allowing the client to refuse medications is an important aspect of respecting their autonomy and right to make decisions about their own care, as long as they are not posing a risk to themselves or others. It is important to communicate with the client about the potential consequences of refusing medications and provide information about the benefits of taking prescribed medications to support their mental health.

The other options are not appropriate for the following reasons:

A- Informing the client that a family member will be called to help: Involving family members can be helpful in some situations, but it should not be used as a way to manipulate the client into compliance with treatment. Calling a family member without the client's consent may also violate the client's privacy and autonomy.

B- Preparing discharge paperwork since the client is refusing assistance: Discharging the client solely because they are refusing medication may not be appropriate or ethical if they are not posing a threat to themselves or others. Discharging the client without addressing the underlying issues may not be in the client's best interest and may not resolve the disruptive behavior.

D- Informing the client that without medications, their mental status will not improve: While it is important to provide the client with information about the benefits of medication, using this information as a threat or coercion tactic may not be therapeutic or effective. The nurse should focus on building a trusting relationship with the client and supporting them in making informed decisions about their care.

Correct Answer is ["0.6"]

Explanation

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.
