A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the client's daily warfarin.
Which of the following laboratory tests should the nurse plan to report to obtain the prescription for the warfarin?

Choice A rationale:

Documenting the desire to be an organ donor in writing is a legal requirement and ensures that the individual's wishes are respected after their passing. It also provides clear guidance to healthcare providers and family members about the individual's decision.

Choice B rationale:

There is no specific age requirement to become an organ donor. People of various ages can register as organ donors, and eligibility often depends on the condition of the organs at the time of death.

Choice C rationale:

Once someone is listed as an organ donor, their name can be removed if they change their mind. It's essential for individuals to inform their family members about their decision and ensure their wishes are respected.

Choice D rationale:

The nurse can indeed be a witness for the consent to donate. Being a witness ensures the authenticity of the individual's decision to become an organ donor and can be helpful in legal and ethical contexts.

The correct answer is choice d. Increasingly severe headache.

Choice A rationale:

Tachycardia is not typically associated with increased intracranial pressure (ICP). In fact, bradycardia (a slower heart rate) is more commonly seen as part of Cushing’s triad, which indicates increased ICP.

Choice B rationale:

Hypotension is not a common sign of increased ICP. Instead, hypertension (high blood pressure) is often observed as the body attempts to maintain cerebral perfusion pressure.

Choice C rationale:

Narrowed pulse pressure is not a typical indicator of increased ICP. Widened pulse pressure (the difference between systolic and diastolic blood pressure) is more commonly associated with increased ICP.

Choice D rationale:

Increasingly severe headache is a classic symptom of increased ICP. As pressure within the skull rises, it can cause significant pain and discomfort, making this a key indicator to monitor in patients with traumatic brain injury.
