A nurse has identified a fluid volume deficit in the patient who has suffered prolonged vomiting and diarrhea.

Which assessment data is most important in identifying that the patient may be developing prerenal acute kidney injury (AKI)?

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.

Choice A rationale
The tripod position helps to improve breathing by allowing the diaphragm to expand more effectively. This position reduces the work of breathing and helps to increase lung capacity, which is beneficial for patients with emphysema.
Choice B rationale
Pursed lip breathing is a technique that helps to keep the airways open longer, allowing more air to escape and reducing the work of breathing. This method helps to improve ventilation and oxygenation in patients with emphysema.
Choice C rationale
Staying current with yearly vaccinations is important for overall health, but it is not a specific strategy for better breathing in emphysema patients. Vaccinations help prevent respiratory infections, which can exacerbate emphysema symptoms.
Choice D rationale
Taking an antihistamine every day is not a recommended strategy for better breathing in emphysema patients. Antihistamines are typically used to treat allergies and may have side effects that could worsen breathing difficulties.
Choice E rationale
Inhaling slowly and deeply helps to maximize lung expansion and improve oxygenation. This technique can help to reduce shortness of breath and improve overall breathing efficiency in patients with emphysema.
Choice F rationale
Sleeping with 2 pillows to prop oneself up helps to reduce the work of breathing by preventing the diaphragm from being compressed. This position can help to improve breathing and reduce shortness of breath during sleep.
Choice G rationale
Measuring peak flow is a useful tool for monitoring lung function, but it is not a specific strategy for better breathing in emphysema patients. Peak flow measurements can help to track the progression of the disease and adjust treatment plans accordingly.
Choice H rationale
Taking a leukotriene inhibitor every day is not a recommended strategy for better breathing in emphysema patients. Leukotriene inhibitors are typically used to treat asthma and may not be effective for emphysema.
