A nurse is caring for a client with congestive heart failure (CHF). Which of the following symptoms would indicate worsening of the condition?

The client reports increased shortness of breath.

The client has a temperature of 37°C (98.6°F).

The client has a blood pressure of 120/80 mmHg.

The client reports occasional dizziness.

Answer and Explanation

The Correct Answer is A

Choice A rationale
Increased shortness of breath is a key symptom of worsening congestive heart failure (CHF). It indicates that the heart is not effectively pumping blood, leading to fluid buildup in the lungs and increased respiratory effort.
Choice B rationale
A temperature of 37°C (98.6°F) is within the normal range and does not indicate worsening CHF. Monitoring the patient’s temperature is important, but it is not a sign of CHF exacerbation.
Choice C rationale
A blood pressure of 120/80 mmHg is within the normal range and does not indicate worsening CHF. Blood pressure should be monitored, but this reading does not suggest an acute issue.
Choice D rationale
Occasional dizziness can be a symptom of many conditions, including CHF, but it is not as specific or critical as increased shortness of breath. It should be monitored, but it does not indicate an immediate worsening of CHF.

Correct Answer is B

Explanation

Choice A rationale
Deep vein thrombosis (DVT) can lead to pulmonary embolism but does not directly cause chest pain and shortness of breath.
Choice B rationale
Pulmonary embolus (PE) is characterized by chest pain, shortness of breath, and hemoptysis (coughing up blood), especially in patients on bed rest.
Choice C rationale
Anemia can cause fatigue and shortness of breath but not typically chest pain and hemoptysis.
Choice D rationale
Right heart failure can cause shortness of breath and edema but not typically chest pain and hemoptysis.

A. It takes about 14 days to develop antibodies and immunity to the disease after vaccine administration. B. The laboratory ran out of blood specimen tubes and is unable to perform the test today. C. It takes about 14 days to develop antigens and immunity to the disease after vaccine administration. D. After receiving the vaccine, you might transmit the communicable disease to the laboratory.

Correct Answer is A

Explanation

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.
