A client is admitted to the emergency department with fever, chills, and severe left costovertebral pain.Which diagnostic test should be prioritized to evaluate the underlying cause of these symptoms?
Complete blood count (CBC).
Urinalysis with culture.
Chest X-ray.
CT scan of the abdomen and pelvis.
The Correct Answer is B
Choice A rationale
A complete blood count (CBC) can provide information about the client's overall health and presence of infection, but it does not specifically address the potential underlying cause related to the urinary system.
Choice B rationale
Urinalysis with culture is the most relevant diagnostic test for evaluating the underlying cause of fever, chills, and severe left costovertebral pain. These symptoms suggest a possible urinary tract infection or pyelonephritis, which can be confirmed with urinalysis and culture.
Choice C rationale
A chest X-ray would not be the priority in this scenario as the symptoms suggest a urinary tract issue rather than a respiratory problem. A chest X-ray is more useful for assessing lung conditions.
Choice D rationale
A CT scan of the abdomen and pelvis can be helpful in evaluating the extent of a urinary tract infection or identifying other causes of abdominal pain, but it is typically not the first-line diagnostic test. Urinalysis with culture is more specific for identifying urinary infections. .

Correct Answer is A
Explanation
Choice A rationale
The oral mucosa is the most reliable indicator of central cyanosis because it reflects the oxygenation of central tissues. When there is a lack of oxygen in the bloodstream, the lips and mucous membranes, such as the oral mucosa, appear blue or cyanotic. This is a clear sign that the central tissues are not receiving adequate oxygenation.
Choice B rationale
The sclera of the eye is not a reliable indicator of central cyanosis. The sclera is white and does not change color due to oxygen levels. Instead, it may become yellow in jaundice or red in inflammation but does not reflect central cyanosis.
Choice C rationale
The ear lobes are peripheral areas and do not reliably indicate central cyanosis. Peripheral cyanosis can occur due to local blood flow issues, and ear lobes can appear blue in cold conditions even when central oxygenation is normal.
Choice D rationale
The soles of the feet, similar to the ear lobes, are peripheral areas and not reliable indicators of central cyanosis. Cyanosis in the feet can result from poor peripheral circulation rather than central hypoxia.
Correct Answer is ["B","C","D"]
Explanation
Choice A rationale
Lying down after meals can increase the risk of acid reflux in individuals with a hiatal hernia. Patients are often advised to remain upright after eating to minimize symptoms.
Choice B rationale
Elevating the head of the bed helps prevent gastric contents from refluxing into the esophagus, reducing symptoms of hiatal hernia and promoting better sleep.
Choice C rationale
Reducing caffeine and spicy foods can help manage symptoms, as these substances can irritate the stomach lining and exacerbate reflux in hiatal hernia patients.
Choice D rationale
Maintaining a healthy weight is important because excess weight can increase abdominal pressure and contribute to the worsening of hiatal hernia symptoms.
Choice E rationale
Drinking less fluid is not typically a recommendation for hiatal hernia. Adequate hydration is important for overall health, and reducing fluid intake may not have a significant impact on symptoms.
