ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse is assessing a client who has acute pancreatitis and is at risk for an acid-base imbalance. For which manifestation of this acid-base imbalance should the nurse assess?

A. Agitation
B. Kussmaul respirations
C. Seizures
D. Positive Chvosteks sign

Correct answer: B

Rationale:

2. A nurse assesses a client who is experiencing an acid-base imbalance. The clients arterial blood gas values are pH 7.34, PaO2 88 mm Hg, PaCO2 38 mm Hg, and HCO3 19 mEq/L. Which assessment should the nurse perform first?

A. . Cardiac rate and rhythm
B. Skin and mucous membranes
C. Musculoskeletal strength
D. Level of orientation

Correct answer: A

Rationale:

3. 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

Rationale:

4. What is the most important regulator of the amount of sodium in the body?

A. Kidneys
B. Small intestine
C. Large intestine
D. Skin

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys play a crucial role in regulating the amount of sodium in the body. They achieve this by filtering blood and controlling the excretion or reabsorption of sodium. The small intestine is primarily responsible for nutrient absorption, not sodium regulation. The large intestine is mainly involved in water absorption and waste elimination, not sodium balance. The skin helps regulate body temperature through sweating and does not directly regulate sodium levels.

5. Under normal circumstances, the kidneys provide the greatest means of water loss. Which organ provides the second greatest means of water loss?

A. Skin
B. Lungs
C. Intestines
D. Muscles

Correct answer: A

Rationale: The correct answer is A: Skin. After the kidneys, the skin is the second largest route of water loss through perspiration. Choice B, Lungs, is incorrect as the lungs primarily exchange gases and do not play a significant role in water loss. Choice C, Intestines, is also incorrect as water loss through the intestines is minimal since most water is reabsorbed during digestion. Choice D, Muscles, is incorrect as muscles are not a major source of water loss in the body.
