The nurse is caring for a client with diabetic ketoacidosis (DKA) receiving intravenous (IV) regular insulin. The most recent potassium was 2.9 mEq/L. The nurse should take which priority action:

Assess the client urine output (UOP)

Obtain a 12-lead electrocardiogram (ECG)

Notify the primary healthcare provider (PMHCP)

Stop the regular insulin infusion

Answer and Explanation

The Correct Answer is C

Choice A rationale: Assessing the UOP is important, but not as urgent as correcting the potassium imbalance.

Choice B rationale: Obtaining a 12-lead ECG can help monitor the cardiac status, but it does not address the cause of the problem.

Choice C rationale: The PMHCP can order potassium replacement to prevent cardiac arrhythmias and other adverse effects of low potassium levels.

Choice D rationale: Stopping the regular insulin infusion can worsen the DKA and increase the risk of cerebral edema and coma.

Correct Answer is B

Explanation

Choice A rationale: Anterior spinal artery syndrome is caused by ischemia of the anterior two-thirds of the spinal cord, resulting in loss of motor function and pain and temperature sensation below the level of the lesion.

Choice B rationale: This is a condition that occurs when the nerve roots in the lower end of the spinal cord are compressed, causing symptoms such as lower back pain, sciatica, saddle anesthesia, bladder and bowel dysfunction, and sexual dysfunction.

Choice C rationale: Horner's syndrome is caused by damage to the sympathetic nerve fibers in the neck or chest, resulting in drooping eyelid, constricted pupil, and lack of sweating on one side of the face.

Choice D rationale: Brown-Séquard syndrome is caused by hemisection of the spinal cord, resulting in ipsilateral loss of motor function and proprioception and contralateral loss of pain and temperature sensation below the level of the lesion.

A. Biopsy B. Urea breath test C. Endoscopy D. Computed tomography (CT) scan

Correct Answer is D

Explanation

Choice A rationale: Biopsy during an endoscopy can help confirm the presence of duodenal ulcers by analyzing tissue samples.

Choice B rationale: Urea breath test is used to detect the presence of Helicobacter pylori, a bacterium associated with duodenal ulcers.

Choice C rationale: Endoscopy is a standard procedure for diagnosing duodenal ulcers by directly visualizing the upper gastrointestinal tract.

Choice D rationale: While a CT scan can be useful in some cases, it's less commonly used for diagnosing duodenal ulcers compared to other diagnostic methods like endoscopy,

biopsy, or urea breath test.
