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 C
Explanation
Choice A rationale
Wearing an N95 mask is appropriate for airborne precautions, such as tuberculosis, but not specifically for MRSA, which requires contact precautions.
Choice B rationale
Wearing a facemask is suitable for droplet precautions, such as influenza, but MRSA is primarily spread through direct contact, not droplets.
Choice C rationale
Using a separate disposable blood pressure cuff for patients with draining wounds helps prevent the spread of MRSA. MRSA can be transmitted via contaminated medical equipment.
Choice D rationale
Strict hand washing measures are essential but should be performed more frequently than once every 8-hour shift. Hand hygiene should be practiced before and after patient contact.
Correct Answer is A
Explanation
Choice A rationale
Septic shock is a severe infection leading to systemic inflammation, characterized by high fever (39°C), low blood pressure (90/60 mmHg), and signs of organ dysfunction. It is a medical emergency requiring immediate intervention.
Choice B rationale
Cardiogenic shock is caused by the heart’s inability to pump blood effectively, leading to hypotension and signs of poor perfusion, but not necessarily high fever.
Choice C rationale
Neurogenic shock results from a disruption in the autonomic pathways, leading to hypotension and bradycardia, but not high fever.
Choice D rationale
Anaphylactic shock is a severe allergic reaction causing hypotension, respiratory distress, and other symptoms, but not typically high fever.
