ATI Fluid Electrolyte and Acid-Base Regulation
1. The nurse in the medical ICU is caring for a patient who is in respiratory acidosis due to inadequate ventilation. What diagnosis could the patient have that could cause inadequate ventilation?
- A. Endocarditis
- B. Multiple myeloma
- C. Guillain-Barr syndrome

Rationale:
2. Diagnostic testing has been ordered to differentiate between normal anion gap acidosis and high anion gap acidosis in an acutely ill patient. What health problem typically precedes normal anion gap acidosis?
- A. Metastases
- B. Excessive potassium intake
- C. Water intoxication
- D. Excessive administration of chloride

Rationale:
3. After administering 40 mEq of potassium chloride, a nurse evaluates the clients response. Which manifestations indicate that treatment is improving the clients hypokalemia? (Select all tha do not t apply.)
- A. Strong productive cough
- B. Active bowel sounds
- C. U waves present on the electrocardiogram (ECG)

Correct answer: C
Rationale:
4. Which electrolyte is important in the formation of the thyroid hormones?
- A. Sodium
- B. Iodine
- C. Iron
- D. Chloride
Correct answer: B
Rationale: Iodine is the correct answer because it is essential for the synthesis of thyroid hormones. The thyroid gland incorporates iodine into thyroid hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones are crucial for regulating metabolism, growth, and development. Sodium, iron, and chloride are not directly involved in the formation of thyroid hormones, making them incorrect choices.
5. Which of the following organs does not contribute to fluid output from the body?
- A. Lungs
- B. Skin
- C. Intestine
- D. Lungs, skin, and intestine
Correct answer: D
Rationale: The correct answer is D. All the listed organs (lungs, skin, and intestines) contribute to fluid loss from the body. Lungs contribute to fluid loss through respiration, skin through sweating, and intestines through excretion. Therefore, none of the organs listed in the options retain fluids within the body. Choices A, B, and C are incorrect because all of these organs play a role in fluid output from the body.
