A patient who is newly diagnosed with erosive esophagitis secondary to gastroesophageal reflux disease (GERD) reports to the home health nurse that there has been only a minimal reduction in symptoms after taking lansoprazole PO for one full week.
Which action should the nurse take?

Choice A rationale:

Checking the patient's temperature again is not a priority at this time. The patient's temperature is within the normal range, and there is no indication that it is the cause of the patient's hypoxia.

Focusing on temperature measurement could delay more crucial interventions to address the patient's breathing difficulty.

Choice B rationale:

While monitoring the patient's heart rate is important, it is not the most immediate priority in this situation. The patient's heart rate is elevated, but it is not dangerously high.

The elevated heart rate is likely a compensatory response to the patient's low oxygen saturation. Addressing the underlying cause of the hypoxia, which is likely respiratory in nature, will also help to stabilize the heart rate.

Choice C rationale:

Observing the patient's breathing is the most important action the nurse can take at this time. The patient's respirations are rapid and shallow, indicating respiratory distress.

This is a serious condition that requires immediate intervention. By observing the patient's breathing, the nurse can assess the severity of the distress and determine the best course of action.

The nurse can observe for signs of increased work of breathing, such as use of accessory muscles, nasal flaring, and retractions. They can also auscultate the lungs to assess for any abnormal breath sounds, such as wheezing or crackles.

This information will help the nurse to determine the underlying cause of the respiratory distress and to initiate appropriate interventions, such as administering oxygen, positioning the patient, or calling for assistance from a respiratory therapist.

Choice D rationale:

Checking the patient's blood pressure is not a priority at this time. The patient's blood pressure is within the normal range. While it is important to monitor the patient's blood pressure, it is not the most immediate concern in this situation.

Choice A rationale:

Pneumonia is the most likely diagnosis given the rapid development of pulmonary infiltrates within a 24-hour period. Pneumonia is an infection of the lungs that can be caused by bacteria, viruses, or fungi. It typically presents with symptoms such as fever, cough, shortness of breath, and chest pain. The presence of pulmonary infiltrates on imaging studies, such as a chest X-ray, is a key diagnostic feature of pneumonia.

The distribution of the infiltrates, involving the lower lobes with a predominance on the right side, is also consistent with pneumonia. This is because the lower lobes are more susceptible to pneumonia due to their anatomy and gravity.

The absence of active processes on Day 1 makes other diagnoses less likely. For example, tuberculosis typically develops more slowly over weeks or months, and bronchitis usually does not cause pulmonary infiltrates.

Pulmonary embolism can cause pulmonary infiltrates, but it would typically be associated with other symptoms such as sudden onset of shortness of breath, chest pain, and tachycardia.

Choice B rationale:

Tuberculosis is a chronic infection that typically develops slowly over weeks or months. It is less likely to cause rapid development of pulmonary infiltrates as seen in this case.

Tuberculosis often involves the upper lobes of the lungs, and it may be associated with other symptoms such as fever, night sweats, and weight loss.

Choice C rationale:

Bronchitis is an inflammation of the bronchi, the large airways that carry air to the lungs. It typically causes a cough, but it does not usually cause pulmonary infiltrates.

Bronchitis is often caused by a virus, and it usually resolves on its own within a few weeks.

Choice D rationale:

Pulmonary embolism is a blockage of a pulmonary artery, one of the blood vessels that carries blood to the lungs. It can cause pulmonary infiltrates, but it would typically be associated with other symptoms such as sudden onset of shortness of breath, chest pain, and tachycardia.

Pulmonary embolism is often caused by a blood clot that travels from a vein in the leg to the lungs.
