A nurse is caring for a client who has heart failure and a prescription for digoxin 125 mcg PO daily. Available is digoxin PO 0.25 mg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the volume of morphine sulfate to administer, we can use the following formula:

Volume (mL) = Dose (mg) / Concentration (mg/mL)

Plugging in the known values:

• Dose = 2 mg
• Concentration = 10 mg/mL

Volume (mL) = 2 mg / 10 mg/mL

Volume (mL) = 0.2 mL

Therefore, the nurse should administer 0.2 mL of morphine sulfate per dose.

Rounded to the nearest tenth: 0.2 mL

A. "I can change who I designate as my health care proxy at any time": This statement is correct. Clients have the right to change their designated health care proxy at any time as long as they are competent to do so. It's important for clients to know that they have flexibility in selecting their proxy based on their preferences and trust in the individual's ability to represent their wishes.
B. "I have to choose a family member as my health proxy": This statement requires clarification. While many clients may choose a family member as their health care proxy, it is not a requirement. Clients have the autonomy to choose any individual they trust to make medical decisions on their behalf, whether it's a family member, friend, or even a legal representative. It's crucial to ensure that the chosen proxy understands the client's wishes and is willing and able to advocate for them.
C. "If I become incapacitated, end-of-life choices will be made by my proxy": This statement is accurate. A health care proxy is designated to make medical decisions on behalf of the client if they become incapacitated and are unable to make decisions for themselves. The proxy is responsible for advocating for the client's wishes, including end-of-life preferences, if outlined in the advance directive or communicated to the proxy beforehand.
D. "The health care proxy does not go into effect until I am incapable of making decisions": This statement is generally correct. Health care proxies typically become active only when the client is deemed incapacitated and unable to make decisions for themselves, as determined by a healthcare provider. However, the specifics may vary depending on state laws and the language of the advance directive document. It's essential for clients to understand when the proxy's authority begins and how it transitions based on their capacity to make decisions.
