A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin?

The client weighs 198 lb, which is equivalent to (198 ÷ 2.2 = 90kg.

Therefore, the amount of mannitol for the test dose is 0.2 g/kg x 90 kg = 18 g. The nurse should administer 18 g of mannitol IV bolus over 5 min as a test dose to the client who has severe oliguria.

Choice A rationale:

While providing end-of-life education is important, it is not a specific requirement under the Patient Self-Determination Act. The act primarily focuses on ensuring that patients' wishes regarding medical treatment and interventions are respected through advance directives.

Choice B rationale:

Documenting in the client's medical record if the client has advance directives is a requirement under the Patient Self-Determination Act. This documentation ensures that healthcare providers are aware of the patient's preferences regarding medical treatment, especially in end-of-life situations. Advance directives may include living wills or durable power of attorney for healthcare, allowing patients to express their choices regarding medical interventions and appointing someone to make decisions on their behalf if they are unable to do so.

Choice C rationale:

Providing the client with a list of eligible individuals who can serve as a health care proxy is not a requirement under the Patient Self-Determination Act. While it can be helpful, the act primarily emphasizes documenting and respecting the patient's existing advance directives.

Choice D rationale:

Ensuring the client has an attorney for assistance with end-of-life documents is not a requirement under the Patient Self-Determination Act. While legal advice can be beneficial, the act primarily focuses on healthcare providers' responsibilities in documenting and respecting patients' advance directives.
