Fluid and Electrolytes ATI Questions

Question 1 of 5

The nurse is evaluating a patient's laboratory results. Based upon the laboratory findings, what results will cause the release of an antidiuretic hormone (ADH)?

Correct Answer: A

Rationale: Increased serum sodium causes increased thirst and the release of ADH by the posterior pituitary gland.

Question 2 of 5

A nurse preparing to start an IV on a newly admitted patient teaches the patient about the procedure and begins to prepare the site. The nurse should always start by:

Correct Answer: C

Rationale: Before preparing the skin, the nurse should ask the patient if he or she is allergic to latex or iodine, which are products commonly used in setting up for IV therapy. A local reaction could result in irritation to the IV site or, in the extreme, it could result in anaphylaxis, which can be life threatening.

Question 3 of 5

The nurse preparing a site for the insertion of an IV catheter should treat excess hair at the site by:

Correct Answer: C

Rationale: Hair can be a source of infection and should be removed by clipping. Shaving the area can cause skin abrasions, and depilatories can irritate the skin.

Question 4 of 5

A nurse is visiting an 84-year-old woman living at home and recovering from hip surgery. The woman seems confused and has poor skin turgor, and she states that 'she stops drinking water early in the day because it is too difficult to get up during the night to go to the bathroom.' The nurse explains to the woman that:

Correct Answer: B

Rationale: The correct answer is B. In elderly patients, fluid deficits can lead to confusion and cognitive impairment. Limiting fluids can disrupt the body's balance, leading to such symptoms. Adjusting the timing of fluids can help maintain hydration without causing nighttime interruptions. Choices A, C, and D are incorrect because they do not address the underlying issue of fluid imbalance causing confusion. Choice A suggests unnecessary hospital readmission and medication adjustments. Choice C incorrectly normalizes confusion post-surgery and suggests it is safe not to urinate at night, which can exacerbate the issue. Choice D inaccurately attributes confusion to sleep loss rather than fluid imbalance.

Question 5 of 5

The triage nurse notes upon assessment in the emergency room that the patient with anxiety is hyperventilating. The nurse is aware that hyperventilation is the most common cause of which acid-base imbalance?

Correct Answer: B

Rationale: The most common cause of acute respiratory alkalosis is hyperventilation. Extreme anxiety can lead to hyperventilation.
