ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse is caring for a client who is having a subclavian central venous catheter inserted. The client begins to report chest pain and difficulty breathing. After administering oxygen, which action should the nurse take next?

Correct answer: B

Rationale:

2. A gerontologic nurse is teaching students about the high incidence and prevalence of dehydration in older adults. What factors contribute to this phenomenon? Select all that do not apply.

Correct answer: D

Rationale:

3. 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.

4. Electrolytes:

Correct answer: D

Rationale: The correct answer is D. Electrolytes are substances that dissociate into ions when dissolved in water, allowing the solution to conduct electricity. Choice A is incorrect because glucose does not form electrolytes when added to water. Choice B is incorrect as it states that electrolytes dissociate but do not form ions, which is inaccurate as electrolytes do form ions in water solutions. Choice C is also incorrect as it states that electrolytes form ions but may not necessarily dissociate, which goes against the definition of electrolytes that must dissociate into ions for conductivity. Therefore, choice D is the most accurate as it correctly describes that electrolytes dissociate in water solutions and form ions, highlighting the essential characteristics of electrolytes.

5. Which hormones increase the amount of water in the body?

Correct answer: D

Rationale: The correct answer is D, ADH and aldosterone. Both antidiuretic hormone (ADH) and aldosterone increase water retention by the kidneys, thereby increasing blood volume. ADH acts on the kidneys to increase water reabsorption, while aldosterone acts on the kidneys to promote sodium reabsorption, leading to water retention. Choice A, ADH, is partially correct as it alone increases water retention. Choice B, aldosterone, is also partially correct as it alone increases water retention. Choice C, ANH (atrial natriuretic hormone), actually decreases water retention by promoting sodium excretion and inhibiting aldosterone release.
