After receiving a vaccination for a communicable disease, the patient was asked to return in 2 to 3 weeks to get an antibody titer and asks why blood testing can’t be done immediately. How should the RN (registered nurse) respond?
It takes about 14 days to develop antibodies and immunity to the disease after vaccine administration.
The laboratory ran out of blood specimen tubes and is unable to perform the test today.
It takes about 14 days to develop antigens and immunity to the disease after vaccine administration.
After receiving the vaccine, you might transmit the communicable disease to the laboratory.
The Correct Answer is A
Choice A rationale
It takes about 14 days to develop antibodies and immunity to the disease after vaccine administration. This is why the patient is asked to return in 2 to 3 weeks for an antibody titer. The immune system needs time to respond to the vaccine and produce detectable levels of antibodies.
Choice B rationale
The laboratory running out of blood specimen tubes is not a valid reason for delaying the antibody titer. This choice does not provide an accurate explanation for the patient.
Choice C rationale
It takes about 14 days to develop antibodies, not antigens, and immunity to the disease after vaccine administration. This choice contains incorrect information about the immune response.
Choice D rationale
After receiving the vaccine, the patient is not likely to transmit the communicable disease to the laboratory. This choice does not provide a valid reason for delaying the antibody titer.

Correct Answer is A
Explanation
Choice A rationale
A hypertensive crisis is characterized by severely elevated blood pressure, which can cause severe headache and blurred vision due to increased intracranial pressure.
Choice B rationale
Migraines can cause severe headaches and visual disturbances, but in a patient with a history of hypertension, a hypertensive crisis is more likely.
Choice C rationale
Sinus infections can cause headaches and facial pain, but not typically blurred vision.
Choice D rationale
Gastroenteritis causes gastrointestinal symptoms like diarrhea and vomiting, not headaches and blurred vision.
Correct Answer is A
Explanation
Choice A rationale
Cerebral ischemia due to an embolus that originates in the left atrium is a common complication of chronic atrial fibrillation (AFib). AFib causes irregular and chaotic electrical signals in the atria, leading to poor blood flow and the formation of blood clots. These clots can travel to the brain, causing a stroke. This is the most acute and severe event associated with chronic AFib.
Choice B rationale
Development of ventricular fibrillation is a life-threatening arrhythmia that can occur in patients with severe heart disease, but it is not a common acute event in chronic AFib. Ventricular fibrillation involves the ventricles and is characterized by rapid, erratic electrical impulses, leading to ineffective heart contractions and sudden cardiac arrest.
Choice C rationale
Ischemia of the cerebellum due to a ruptured intracranial aneurysm is not directly related to chronic AFib. While AFib increases the risk of stroke, it does not specifically cause aneurysms or cerebellar ischemia. Aneurysms are typically related to other risk factors such as hypertension and vascular abnormalities.
Choice D rationale
Prolonged capillary refill secondary to a complete lack of cardiac output is a sign of severe cardiac dysfunction or shock. While AFib can lead to heart failure and reduced cardiac output, it does not typically cause a complete lack of cardiac output. The most acute event related to AFib is the formation of emboli and subsequent stroke.
