Correct Answer is {"dropdown-group-1":"D"}

Explanation

A. Modify: Clients do not have the legal or ethical authority to independently alter prescribed medications or treatments, as this could compromise safety and therapeutic effectiveness. Changes must be approved by the prescribing provider.

B. Sell: Clients cannot sell prescribed medications; doing so is illegal and poses serious safety and legal risks. Medications are intended solely for the individual for whom they are prescribed.

C. Delay: While clients may request to delay treatments, this is not an inherent right. Delays require negotiation with healthcare providers and consideration of clinical consequences.

D. Refuse: Clients have the right to refuse medications or treatments based on autonomy, informed consent, and personal or religious beliefs. Nurses must respect this decision, provide education about risks and benefits, and document the refusal while ensuring safety.

Correct Answer is C

Explanation

Calculation:

  • Identify the ordered dose and available concentration

Ordered Dose: 2 mg

Available Concentration: 4 mg/2 mL

  • Calculate the volume to administer

Volume to administer = (Ordered Dose ÷ Available Dose) × Volume of Concentration

Volume to administer = (2 ÷ 4) × 2

Volume to administer = 0.5 × 2

= 1 mL
