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 D
Explanation
Choice A rationale
Hypokalemia can cause muscle weakness and cramps, but it does not typically lead to severe muscle spasms causing exhaustion. The patient’s symptoms of lethargy and weakness are more likely related to electrolyte imbalances and dehydration rather than muscle spasms.
Choice B rationale
While low potassium levels can affect cellular metabolism, the primary issue here is not glycolysis. The patient’s symptoms are more consistent with dehydration and electrolyte imbalances rather than a metabolic shift to glycolysis.
Choice C rationale
Hypokalemia can cause cells to become hyperpolarized, leading to muscle weakness and decreased reflexes. However, the patient’s symptoms of lethargy and weakness are more likely due to dehydration and electrolyte imbalances rather than cellular hyperpolarization.
Choice D rationale
Hypernatremia, or high sodium levels, can cause cellular dehydration, leading to symptoms such as lethargy and weakness. The patient’s lab results and clinical presentation are consistent with hypernatremia-induced cellular dehydration, which explains his symptoms.
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.
