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.

Answer and Explanation

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 D

Explanation

Choice D rationale

Ensuring a clear airway is the priority intervention in cases of diabetic ketoacidosis with hypoxia. Hypoxia refers to a deficiency in the amount of oxygen reaching tissues. Without a clear airway, oxygen cannot be effectively delivered to the lungs, and subsequently to the bloodstream and tissues. Addressing the client's airway ensures that oxygenation can be improved promptly, which is critical in preventing further complications and maintaining vital functions.

Choice A rationale

While it is important to monitor blood glucose levels in diabetic ketoacidosis, it is not the immediate priority when the client is also experiencing hypoxia. Blood glucose testing does not directly address the oxygen deficiency, which needs urgent attention to prevent severe outcomes.

Choice B rationale

Administering a bronchodilator can help improve breathing in some cases; however, it is not the first step in managing hypoxia and diabetic ketoacidosis. The primary focus should be on ensuring a patent airway to facilitate adequate oxygen delivery.

Choice C rationale

Monitoring vital signs is essential in managing any acute condition; however, in this scenario, ensuring a clear airway to address hypoxia is the most critical intervention. Monitoring alone does not resolve the immediate issue of oxygen deprivation.
