The best answer is C: Obtain stat CT scan or MRI.

Here's Why: Unnecessary arterial punctures should be avoided due to the possibility of creating a contraindication to the use of fibrinolytic therapy. The verbal symptoms assist in reaching a diagnosis, but do not require urgent evaluation. Unless there are specific cardiac symptoms, angiography of coronary vessels is not part of the routine stroke evaluation. Early determination of the stroke’s etiology via CT or MRI scans allows timely implementation of the proper intervention (fibrinolytic vs. surgical).

The best answer is A: True.

Here's Why: Children who desaturate enough hemoglobin to produce cyanosis are at high risk for cardiopulmonary arrest. Cyanosis should be treated immediately to prevent organ damage and/or arrest.

The best answer is B: False.

Here's Why: Even if the patient has lost the capacity to understand and participate in his/her care, federal law prohibits disclosure of confidential information without the patient’s express permission. Thus, if the patient has lost the ability to participate, the legal duty lies with the person with the contract to provide proper health care. In the event that the patient has legally assigned someone as a surrogate decision-maker, that person becomes the patient in the eyes of the law and is empowered to have access to the medical record, and make decisions on behalf of the patient. Some states have laws that create a “lineage” of decision makers. All practitioners should know their state law in the area, and encourage all of their patients to assign durable power of attorney for health care prior to a catastrophic event.
