A teenage client is admitted to the emergency department following a bee sting. The client arrives with a body rash and 30 minutes later becomes short of breath.
The client's vital signs are a heart rate of 130 beats/minute, respirations of 40 breaths/minute, and a blood pressure of 90/52 mm Hg. The client is exhibiting clinical manifestations of which type of immune reaction?

Choice A rationale:

Diminished breath sounds in the right lung: This finding suggests that there is still some inflammation or fluid in the right lung, which is not consistent with fully effective treatment. Normal breath sounds should be clear and equal bilaterally.

PaCO2 55 mm Hg on a blood gas: This finding is slightly elevated, indicating that the patient may be having some difficulty clearing carbon dioxide from the lungs. A normal PaCO2 is 35-45 mm Hg.

Rhonchi in the right lung: Rhonchi are a type of abnormal breath sound that is caused by secretions in the airways. This finding suggests that there is still some inflammation or infection in the right lung.

Choice B rationale:

Oxygen saturation greater than 94%: This finding is within the normal range and indicates that the patient is getting enough oxygen.

Client ambulates without shortness of breath: This finding is a positive sign that the patient's respiratory status is improving. Symmetric chest expansion: This finding indicates that both lungs are expanding equally, which is a good sign.

Choice C rationale:

The assessment findings are mixed, with some findings suggesting improvement (oxygen saturation, ambulation without shortness of breath, symmetric chest expansion) and some findings suggesting that the infection is not fully resolved (diminished breath sounds, elevated PaCO2, rhonchi). This suggests that the treatment has been partially effective, but that the patient may need further treatment to fully resolve the pneumonia.

Choice D rationale:

It is important to evaluate the effectiveness of treatment over time, but the assessment findings in this case are clear enough to determine that the treatment has been partially effective.

The correct answer is choice A, C, and D.

Choice A rationale:

The patient’s oxygen saturation is at 94%, which is just below the normal range of 95-100% for healthy adults breathing room air. Administering oxygen 2 to 4 liters to maintain oxygen saturation at or above 95% is a standard intervention to ensure adequate oxygenation.

Choice B rationale:

A stat ventilation/perfusion (V/Q) scan is typically ordered for suspected pulmonary embolism, which is not indicated by the patient’s current data. The patient’s symptoms do not specifically suggest a V/Q mismatch that would necessitate this diagnostic test.

Choice C rationale:

A chest x-ray is a common diagnostic tool for evaluating the lungs and heart, especially when a patient presents with symptoms that may indicate respiratory or cardiac issues. Given the patient’s temperature and heart rate, which are slightly elevated, a chest x-ray can help identify any potential underlying conditions.

Choice D rationale:

Ordering a CBC, BMP, and blood cultures can help identify the cause of the patient’s fever and tachycardia. These tests provide valuable information about the patient’s immune response, electrolyte balance, kidney function, and whether there is a bacterial infection.

Choice E rationale:

While sending sputum for culture and sensitivity could be helpful if a respiratory infection is suspected, the patient’s data does not strongly indicate a respiratory infection as the primary issue. Therefore, this test may not be the most immediate need.
