A patient with acute myelogenous leukemia (AML) asks the nurse why their bones are making more white blood cells when they already have so many. The nurse clarifies that the large number of leukemic white cells they have:
attempt to take over the function of the abnormal white blood cells.
will help to protect them against infection.
are larger in size than normal white blood cells and clog the bone marrow.
are not as effective as normal white cells to protect against infection.
The Correct Answer is D
Choice A reason: This is not a correct explanation for the large number of leukemic white cells. Leukemic white cells are abnormal white blood cells that do not function properly. They do not attempt to take over the function of the abnormal white blood cells, but rather crowd out the normal ones.
Choice B reason: This is also not a correct explanation for the large number of leukemic white cells. Leukemic white cells do not help to protect against infection, but rather increase the risk of infection. They impair the immune system's ability to fight off bacteria, viruses, and other pathogens.
Choice C reason: This is a partially correct explanation for the large number of leukemic white cells. Leukemic white cells are larger in size than normal white blood cells, and they can clog the bone marrow. This can interfere with the production of other blood cells, such as red blood cells and platelets. However, this is not the only reason for the large number of leukemic white cells.
Choice D reason: This is the best explanation for the large number of leukemic white cells. Leukemic white cells are not as effective as normal white cells to protect against infection, because they are immature and dysfunctional. They do not respond to signals from the immune system, and they do not recognize or destroy foreign invaders. They also prevent the normal white cells from doing their job.

Correct Answer is B
Explanation
Choice A reason: Notifying the health care provider of the patient's status is an important action, but not the first priority. The nurse should first assess the patient for any possible triggers of the autonomic dysreflexia, which is a life-threatening condition that occurs in patients with spinal cord injury above the level of T6. It is characterized by a sudden and severe increase in blood pressure, flushing, sweating, headache, and blurred vision.
Choice B reason: Assessing patient for tight clothing around the waist or a full bladder is the first priority action. These are common triggers of autonomic dysreflexia, which cause irritation or stimulation of the nerves below the level of injury. The nurse should remove any tight clothing, catheterize the patient if needed, or perform a bowel evacuation to relieve the pressure and prevent further complications.
Choice C reason: Reviewing the medication administration record for an antihypertensive order is a secondary action, after identifying and removing the trigger of autonomic dysreflexia. The nurse should administer the prescribed antihypertensive medication, such as nifedipine or nitroglycerin, to lower the blood pressure and prevent stroke, seizure, or cardiac arrest.
Choice D reason: Initiating oxygen via a nasal cannula and elevating patient's legs is not an appropriate action for a patient with autonomic dysreflexia. Oxygen therapy is not indicated for this condition, unless the patient has hypoxia or respiratory distress. Elevating the patient's legs can worsen the blood pressure by increasing the venous return and the cardiac output. The nurse should keep the patient in a sitting position to promote the blood flow to the lower extremities and reduce the blood pressure.
Correct Answer is B
Explanation
Choice A reason: This is incorrect. Numbness of the fingers is not an early sign of a migraine with an aura, but rather a symptom of a sensory aura, which occurs after the visual aura and before the headache. A sensory aura is a tingling or numb sensation that affects one side of the body, usually the face, arm, or hand.
Choice B reason: This is correct. Visual disturbances are an early sign of a migraine with an aura, which precedes the headache by 10 to 60 minutes. A visual aura is a temporary change in vision, such as seeing flashes, zigzags, blind spots, or shimmering shapes.
Choice C reason: This is incorrect. Lethargy is not an early sign of a migraine with an aura, but rather a symptom of the postdrome phase, which occurs after the headache subsides. The postdrome phase is a period of recovery, where the patient may feel tired, weak, or confused.
Choice D reason: This is incorrect. Vertigo is not an early sign of a migraine with an aura, but rather a symptom of a vestibular migraine, which is a type of migraine that affects the balance and hearing. Vertigo is a sensation of spinning or dizziness that may occur with or without a headache.
