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
The absence of burning epigastric pain after eating indicates that the treatment for peptic ulcer disease (PUD) secondary to H. pylori has been effective. This suggests that the ulcer has healed and the inflammation has subsided.
Choice B rationale
Coffee-ground emesis indicates the presence of blood in the vomit, which suggests ongoing bleeding and is not a sign of effective treatment for PUD.
Choice C rationale
A decrease in alcohol intake is beneficial for overall health but does not directly indicate the effectiveness of treatment for PUD secondary to H. pylori.
Choice D rationale
Normalization of hemoglobin levels is important but does not specifically indicate the effectiveness of treatment for PUD secondary to H. pylori. The primary indicator would be the resolution of symptoms such as burning epigastric pain.
Correct Answer is A
Explanation
Choice A rationale
Serum amylase is typically elevated in acute pancreatitis. It is one of the key diagnostic markers for this condition.
Choice B rationale
Serum potassium levels are not typically elevated in acute pancreatitis. Potassium levels are more commonly associated with kidney function and electrolyte balance.
Choice C rationale
Serum calcium levels are usually decreased, not elevated, in acute pancreatitis. Hypocalcemia can occur due to fat saponification in the pancreas.
Choice D rationale
Serum sodium levels are not typically elevated in acute pancreatitis. Sodium levels are more related to overall fluid balance and kidney function.
