A nurse is preparing to administer medication to a preschooler and must convert the child's weight from pounds to kilograms. The child weighs 30 lb. How many kilograms does the child weigh?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

The correct answer is choiceC. “You should cleanse your eye from the inner to the outer edge prior to putting in the drops.”

Choice A rationale:

Looking to the side when putting in eye drops is not recommended.The correct technique involves looking up to help the drop fall into the eye more easily.

Choice B rationale:

Putting drops directly in the center of the eyeball can cause discomfort and may not be effective.The drops should be placed in the lower eyelid pocket.

Choice C rationale:

Cleansing the eye from the inner to the outer edge helps remove any debris or discharge, reducing the risk of infection and ensuring the drops are effective.

Choice D rationale:

Pressing on the tear duct after putting in eye drops can help prevent the medication from draining away too quickly, ensuring better absorption.

The correct answer is choice A: "I know that I can change my advance directives if I need to in the future."

Choice A rationale:

This statement indicates an understanding of advance directives. Advance directives are legal documents that allow individuals to communicate their preferences for medical treatment in case they become unable to make decisions themselves. It's important for clients to know that they can update or change their advance directives if their wishes or circumstances change over time.

Choice B rationale:

The statement that the health care surrogate will make decisions as soon as the power of attorney is signed is not accurate. Generally, a health care surrogate's authority to make decisions comes into effect when the primary individual is no longer able to make decisions themselves. Signing a power of attorney alone does not grant immediate decision-making power to the surrogate.

Choice C rationale:

The family generally cannot overrule the decisions made by a designated health care surrogate. Once an individual designates a surrogate and provides clear instructions through advance directives, the surrogate's decisions are legally binding and typically override the family's input.

Choice D rationale:

Advance directives are not universally valid across states. Laws and regulations regarding advance directives can vary significantly from state to state. It's important for clients to understand that if they relocate, they may need to update their advance directives to comply with the laws of the new state.
