ATI Fluid Electrolyte and Acid-Base Regulation
1. You are making initial shift assessments on your patients. While assessing one patients peripheral IV site, you note edema around the insertion site. How should you document this complication related to IV therapy?
- A. Air emboli
- B. Phlebitis
- C. Infiltration
- D. Fluid overload
Correct answer: C
Rationale:
2. Which hormone is made in the pituitary gland and increases water absorption in the kidney?
- A. Intracellular fluid
- B. Interstitial fluid
- C. Plasma
- D. ADH
Correct answer: D
Rationale: The correct answer is D, ADH (Antidiuretic hormone). ADH is produced by the pituitary gland and functions to increase water reabsorption in the kidneys. Choices A, B, and C are incorrect as they do not refer to a hormone responsible for increasing water absorption in the kidney.
3. A nurse assesses a client who has a radial artery catheter. Which assessment should the nurse complete first?
- A. . Amount of pressure in fluid container
- B. Date of catheter tubing change
- C. Percent of heparin in infusion container
- D. . Presence of an ulnar pulse
Correct answer: D
Rationale:
4. What happens first in dehydration?
- A. Intercellular fluid volume drops first.
- B. Plasma volume drops first.
- C. Interstitial fluid drops first.
- D. Neither interstitial nor intracellular fluid volume are affected.
Correct answer: C
Rationale: In dehydration, the body first draws fluid from the interstitial space to maintain blood volume, leading to a decrease in interstitial fluid volume. This is why choice C is correct. Choice A is incorrect because intracellular fluid is not the first to be affected. Choice B is also incorrect as plasma volume reduction typically occurs after interstitial fluid loss. Choice D is incorrect as dehydration impacts both interstitial and intracellular fluid volumes.
5. The ICU nurse is caring for a patient who experienced trauma in a workplace accident. The patient is complaining of having trouble breathing with abdominal pain. An ABG reveals the following results: pH 7.28, PaCO2 50 mm Hg, HCO3 23 mEq/L. The nurse should recognize the likelihood of what acidbase disorder?
- A. Respiratory acidosis
- B. Metabolic alkalosis
- C. Respiratory alkalosis
- D. Mixed acidbase disorder
Correct answer: D
